Medicare Program; Prospective Payment System for Long-Term Care 
Hospitals: Annual Payment Rate Updates and Policy Changes

AGENCY: Centers for Medicare & Medicaid Services (CMS), HHS.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: This final rule establishes the annual update of the payment 
rates for the Medicare prospective payment system (PPS) for inpatient 
hospital services provided by long-term care hospitals (LTCHs). It also 
changes the annual period for which the rates are effective. The rates 
will be effective from July 1 to June 30 instead of from October 1 
through September 30, establishing a ``long-term care hospital rate 
year'' (LTCH PPS rate year). We also change the publication schedule 
for these updates to allow for an effective date of July 1. The payment 
amounts and factors used to determine the updated Federal rates that 
are described in this final rule have been determined based on this 
revised LTCH PPS rate year. The annual update of the long-term care 
diagnosis-related groups (LTC-DRG) classifications and relative weights 
remains linked to the annual adjustments of the acute care hospital 
inpatient diagnosis-related group system, and will continue to be 
effective each October 1.
    The outlier threshold for July 1, 2003, through June 30, 2004, is 
also derived from the LTCH PPS rate year calculations.
    In addition, we are making an adjustment to the short-stay outlier 
policy for certain LTCHs and a policy change eliminating bed-number 
restrictions for pre-1997 LTCHs that have established satellite 
facilities and elect to be paid 100 percent of the Federal rate or when 
the LTCH is fully phased-in to 100 percent of the Federal prospective 
rate after the transition period.

EFFECTIVE DATE: The provisions of this final rule are effective June 
30, 2003.

I. Background

A. Legislative and Regulatory Authority

    The Medicare, Medicaid, and SCHIP (State Children's Health 
Insurance Program) Balanced Budget Refinement Act of 1999 (BBRA) (Pub. 
L. 106-113) and the Medicare, Medicaid, and SCHIP Benefits Improvement 
and Protection Act of 2000 (BIPA) (Pub. L.106-554) provide for payment 
for both the operating and capital-related costs of hospital inpatient 
stays in long-term care hospitals (LTCHs) under Medicare part A based 
on prospectively set rates. The Medicare prospective payment system for 
LTCHs applies to hospitals described in section 1886(d)(1)(B)(iv) of 
the Social Security Act (the Act), effective for cost reporting periods 
beginning on or after October 1, 2002.
    Section 1886(d)(1)(B)(iv)(I) of the Act defines a LTCH as ``a 
hospital which has an average inpatient length of stay (as determined 
by the Secretary) of greater than 25 days.'' Section 
1886(d)(1)(B)(iv)(II) of the Act also provides an alternative 
definition of LTCHs: Specifically, a hospital that first received 
payment under section 1886(d) of the Act in 1986 and has an average 
inpatient length of stay (as determined by the Secretary) of greater 
than 20 days and has 80 percent or more of its annual Medicare 
inpatient discharges with a principal diagnosis that reflects a finding 
of neoplastic disease in the 12-month cost reporting period ending in 
FY 1997.
    Section 123 of Public Law 106-113 requires the prospective payment 
system for LTCHs to be a per discharge system with a diagnosis-related 
group (DRG) based patient classification system that reflects the 
differences in patient resources and costs in LTCHs while maintaining 
budget neutrality.
    Section 307(b)(1) of Public Law 106-554, among other things, 
mandates that the Secretary shall examine and may provide for 
adjustments to payments under the LTCH PPS, including adjustments to 
DRG weights, area wage adjustments, geographic reclassification, 
outliers, updates, and a disproportionate share adjustment.
    In a Federal Register document issued on August 30, 2002 (67 FR 
55954), we implemented the LTCH PPS authorized under Public Law 106-113 
and Public Law 106-554. This system uses information from LTCH patient 
records to classify patients into distinct long-term care diagnosis-
related groups (LTC-DRGs) based on clinical characteristics and 
expected resource needs. Payments are calculated for each LTC-DRG and 
provisions are made for appropriate payment adjustments. Payment rates 
under the LTCH PPS are updated annually and published in the Federal 
Register.
    The LTCH PPS replaced the reasonable cost-based payment system 
under the Tax Equity and Fiscal Responsibility Act of 1982 (TEFRA), 
Public Law 97-248, for payments for inpatient services provided by a 
LTCH with a cost reporting period beginning on or after October 1, 
2002. (The regulations implementing the TEFRA (reasonable cost-based) 
payment provisions are located at 42 CFR part 413.) With the 
implementation of the prospective payment system for inpatient acute 
care hospitals authorized by the Social Security Amendments of 1983 
(Public Law 98-21), which added section 1886(d) to the Act, certain 
hospitals, including LTCHs, were excluded from the PPS for acute care 
hospitals and were paid their reasonable costs for inpatient services 
subject to a per discharge limitation or target amount under the TEFRA 
system. For each cost reporting period, a hospital-specific ceiling on 
payments was determined by multiplying the hospital's updated target 
amount by the number of total current year Medicare discharges. The 
August 30, 2002, final rule further details payment policy under the 
TEFRA system (67 FR 55954).
    In the August 30, 2002, final rule, we presented an in-depth 
discussion of the LTCH PPS, including the patient classification 
system, relative weights, payment rates, additional payments, and the 
budget neutrality requirements mandated by section 123 of Public Law 
106-113. The same final rule, that established regulations for the LTCH 
PPS under 42 CFR part 412, subpart O, also contained provisions related 
to covered inpatient services, limitation on charges to beneficiaries, 
medical review requirements, furnishing of inpatient hospital services 
directly or under arrangement, and reporting and recordkeeping 
requirements.
    We refer readers to the August 30, 2002, final rule (67 FR 
55954)for a comprehensive discussion of the research and data that 
supported the establishment of the LTCH PPS.

B. Criteria for Classification as a LTCH

    LTCHs must have a provider agreement with Medicare and (1) must 
have an average Medicare inpatient length of stay of greater than 25 
days, or (2), for a hospital that was first excluded from the PPS in 
1986, must have an average inpatient length of stay for all patients, 
including both Medicare and non-Medicare inpatients, of greater than 20 
days and demonstrate that at least 80 percent of its annual Medicare 
inpatient discharges in the 12-month cost reporting period ending in FY 
1997 have a principle diagnosis that reflects a finding of neoplastic 
disease. Subject to the provisions of Sec.  412.23(e)(3), for the first 
type of LTCHs as noted above, the average Medicare inpatient length of 
stay is determined based on all covered and noncovered days of stay of 
Medicare patients as calculated by dividing the total number of covered 
and noncovered days of stay of Medicare inpatients (less leave or pass 
days) by the number of total Medicare discharges for the hospital's 
most recent complete cost reporting period. Fiscal intermediaries 
verify that LTCHs meet the average length of stay requirements. We note 
that the inpatient days of a patient who is admitted to a LTCH without 
any remaining Medicare days of coverage, regardless of the fact that 
the patient is a Medicare beneficiary, will not be included in the 
above calculation. Because Medicare would not be paying for any of the 
patient's treatment, data on the patient's stay would not be included 
in our systems. In order for noncovered days of a LTCH

[[Page 34124]]

hospitalization to be included, a patient must have at least one 
remaining benefit day as described in Sec.  409.61.
    The fiscal intermediary's determination of whether or not a 
hospital qualifies as an LTCH is based on the hospital's discharge data 
from its most recent cost reporting period and is effective at the 
start of the hospital's next cost reporting period, as set forth under 
Sec.  412.22(d). If a hospital does not meet the length of stay 
requirement, the hospital may provide the intermediary with data 
indicating a change in the hospital's average length of stay by the 
same method for the immediately preceding 6-month period (Sec.  
412.23(e)(3)(ii)). (For procedural efficiency and in order to comply 
with the timing requirement of Sec.  412.22(d), we have a longstanding 
policy of allowing hospitals to submit data for a period greater than 
5-months for this purpose.) Requirements for hospitals seeking 
classification as LTCHs that have undergone a change in ownership, as 
described in Sec.  489.18, are set forth in Sec.  412.23(e)(3)(iii).
    LTCHs that exist as hospitals-within-hospitals or satellite 
facilities must also meet the criteria set forth in Sec.  412.22(e) or 
Sec.  412.22(h), respectively, to be excluded from the IPPS and paid 
under the LTCH PPS.
    The following hospitals are paid under special payment provisions, 
as described in Sec.  412.22(c) and, therefore, are not subject to the 
LTCH PPS rules:
    [sbull] Veterans Administration hospitals.
    [sbull] Hospitals that are reimbursed under State cost control 
systems approved under 42 CFR Part 403.
    [sbull] Hospitals that are reimbursed in accordance with 
demonstration projects authorized under section 402(a) of Public Law 
90-248 (42 U.S.C. 1395b-1) or section 222(a) of Public Law 92-603 (42 
U.S.C. 1395b-1 (note)) (statewide all-payer systems, subject to the 
rate-of-increase test at section 1814(b) of the Act).
    [sbull] Nonparticipating hospitals furnishing emergency services to 
Medicare beneficiaries.

C. Transition Period for Implementation of the LTCH PPS

    In the August 30, 2002, final rule, we provided for a 5-year 
transition period from cost-based reimbursement to fully Federal 
prospective payment for LTCHs (67 FR 56038). During the 5-year period, 
two payment percentages are to be used to determine a LTCH's total 
payment under the PPS. The blend percentages are as follows:

------------------------------------------------------------------------
                                            Prospective     Cost-based
 Cost reporting periods beginning on or       payment      reimbursement
                  after                    Federal rate        rate
                                            percentage      percentage
------------------------------------------------------------------------
October 1, 2002.........................              20              80
October 1, 2003.........................              40              60
October 1, 2004.........................              60              40
October 1, 2005.........................              80              20
October 1, 2006.........................             100               0
------------------------------------------------------------------------

D. Limitation on Charges to Beneficiaries

    In the August 30, 2002, final rule, we presented an in-depth 
discussion of beneficiary liability under the LTCH prospective payment 
system (67 FR 55974-55975). Under Sec.  412.507, as consistent with 
other established hospital prospective payment systems, a LTCH may not 
bill a Medicare beneficiary for more than the deductible and 
coinsurance amounts as specified under Sec. Sec.  409.82, 409.83, and 
409.87 and for items and services as specified under Sec.  489.30(a), 
if the Medicare payment to the LTCH is the full LTC-DRG payment amount. 
However, if the Medicare payment was for a short-stay outlier case 
(Sec.  412.529) that was less than the full LTC-DRG payment amount, the 
LTCH could also charge the beneficiary for services for which the costs 
of those services or the days those services were provided were not a 
basis for calculating the Medicare short-stay outlier payment (Sec.  
412.507).
    Since the origin of the Medicare system, the intent of our 
regulations has been to set limits on beneficiary liability and to 
clearly establish the circumstances under which the beneficiary would 
be required to assume responsibility for payment; that is, upon 
exhausting benefits described in 42 CFR part 409, subpart F. The 
discussion in the August 30, 2002, final rule was not meant to 
establish rates or payments for, or define, Medicare-eligible expenses. 
While we regulate beneficiary liability for coinsurance and deductibles 
for hospital stays that are covered by Medicare, payments from Medigap 
insurers to providers for inpatient hospital coverage after Medicare 
benefits are exhausted are not regulated by us. Furthermore, 
regulations beginning at Sec.  403.200 and the 1991 National 
Association of Insurance Commissioners (NAIC) Model Regulation for 
Medicare Supplemental Insurance, which was incorporated by reference 
into section 1882 of the Act, govern the relationship between Medigap 
insurers and beneficiaries.

E. System Implementation for the LTCH PPS

    When we established the regulations to implement the LTCH PPS on 
August 30, 2002 (67 FR 55954), effective for cost reporting periods 
that began on or after October 1, 2002, we did not have computer system 
changes in place that were necessary to accommodate claims processing 
and payment under the system. However, after January 1, 2003, we made 
the necessary system changes. Accordingly, after January 1, 2003, the 
fiscal intermediary has been required to reconcile the payment amounts 
that had been made to LTCHs for all covered inpatient hospital services 
furnished to Medicare beneficiaries from cost reporting periods that 
began on or after October 1, 2002, through January 1, 2003, with the 
amounts that were payable under the LTCH PPS methodology. Because the 
LTCH PPS was effective at the start of the LTCH's first cost reporting 
period that began on or after October 1, 2002, only those LTCHs with 
cost reporting periods that started October 1, 2002, through January 1, 
2003, will experience the payment reconciliation necessitated by this 
3-month period prior to systems implementation. The claims submission 
procedure of using ICD-9-CM codes has not changed following the systems 
implementation of the LTCH PPS.
    We also want to note that as of October 16, 2002, a LTCH that was 
required to comply with the Administrative Simplification Standards 
under the Health Insurance Portability and Accountability Act (HIPAA) 
(Pub. L. 104-191) and that had not obtained an extension in compliance 
with the Administrative Compliance Act (Pub. L. 107-105) is obligated 
to comply with the standards for submitting claim forms to the

[[Page 34125]]

LTCH's Medicare fiscal intermediary (45 CFR 162.1002 and 45 CFR 
162.1102). Beginning October 16, 2003, LTCHs that obtained an extension 
and that are required to comply with the HIPPA Administrative 
Simplification Standards must start submitting electronic claims in 
compliance with the HIPPA regulations cited above, among others.

II. Publication of Proposed Rulemaking

    On March 7, 2003, we published a proposed rule in the Federal 
Register (67 FR 11234) that set forth the proposed annual update of the 
payment rates for the Medicare prospective payment system (PPS) for 
inpatient hospital services provided by long-term care hospitals 
(LTCHs). In that rule, we proposed to change the annual period during 
which the updated payment rates for the LTCH PPS would be effective 
from October 1 through September 30 to a LTCH PPS rate year from July 1 
through June 30. We also proposed to change the publication schedule 
for these updates to allow for an effective date of July 1. The 
proposed payment amounts and factors used to determine the proposed 
updated Federal rates that were described in the March 7, 2003, 
proposed rule were determined based on the proposed revised update LTCH 
PPS rate year. However, the annual update of the long-term care 
diagnosis-related groups (LTC-DRG) classifications and relative weights 
remain linked to the annual adjustments of the acute care hospital 
inpatient diagnosis-related group system, effective each October 1. In 
the March 7, 2003, proposed rule, we also proposed the outlier 
threshold for July 1, 2003, through June 30, 2004, that was derived 
from the proposed LTCH PPS rate year calculations. We also proposed a 
change for outlier payments under the LTCH PPS. In addition, we 
proposed a policy change eliminating bed-number restrictions for pre-
1997 LTCHs that have established satellite facilities and that elect to 
be paid 100 percent of the Federal rate or when the LTCH is fully 
phased-in to 100 percent of the Federal prospective rate after the 
transition period.
    We received a total of 32 timely items of correspondence containing 
multiple comments on the proposed rule. The major issues addressed by 
the commenters included: The establishment of the LTCH PPS rate year 
and its relation to the update of the Federal rates; the LTC-DRGs and 
the wage index; satellite policy and budget neutrality calculations; 
high-cost and short-stay outliers; market basket and labor share; 
disproportionate share (DSH) and Graduate Medical Education (GME) 
policies.
    Summaries of the public comments received and our responses to 
those comments are described below under the appropriate subject 
heading.

III. Summary of the Major Contents of This Final Rule

    In this final rule, we set forth the annual update to the payment 
rates for the Medicare LTCH PPS and make other policy changes. The 
following is a summary of the major areas that we are addressing in 
this final rule:

A. Change in the Annual Update

    We are changing the annual update to the Federal payment rate under 
the LTCH PPS from the Federal fiscal year (October 1 through September 
30) to a ``LTCH PPS rate year'' of July l through June 30, beginning 
July l, 2003, as discussed in section IV. of this preamble. (In this 
final rule, we define the LTCH PPS rate year as the period from July 1 
to June 30 for updates to the LTCH PPS.) As noted below, we will now 
publish information on the annual update in the Federal Register on or 
before May 1 prior to the start of each long-term care hospital 
prospective payment system rate year that begins July 1, unless for 
good cause it is published after May 1, but before June 1. We have 
already noted that the annual update of the LTC-DRGs will be published 
in the proposed and final rules for the IPPS. We also recognize that it 
may be necessary to address issues affecting LTCHs at a time that does 
not conform to the schedule above. In such a situation, we would use 
another Federal Register document (that is, the acute care hospital 
inpatient prospective payment system (IPPS) proposed rule or final 
rule) as the vehicle to present that issue.

B. Update Changes

    [sbull] In section IV. of this preamble, the annual update of the 
LTC-DRG classifications and relative weights remain linked to the 
annual adjustments of the acute care hospital inpatient DRG system, 
which are based on the annual revisions to the International 
Classification of Diseases, Ninth Revision, Clinical Modification (ICD-
9-CM) codes, effective each October 1.
    [sbull] In section VI. of this preamble, we discuss a policy change 
on how Medicare payment under the LTCH PPS will be made to certain 
LTCHs that have satellite facilities.
    [sbull] In sections VII. through XI. of this preamble, we discuss 
our determination of the LTCH PPS rates that are applicable to the LTCH 
PPS rate year of July 1, 2003, through June 30, 2004, including 
revisions to the wage index, the excluded hospital with capital market 
basket that will be applied to the current standard Federal rate to 
determine the prospective payment rates, the applicable adjustments to 
payments, the outlier threshold, the short-stay outlier policy for 
certain LTCHs, the transition period, and the budget neutrality factor.
    [sbull] In section XII. of this preamble, we discuss our continuing 
monitoring efforts to evaluate the LTCH PPS.
    [sbull] In section XIV. of this preamble, we set forth an analysis 
of the impact of the changes in this final rule on Medicare 
expenditures and on Medicare-participating LTCHs and Medicare 
beneficiaries.

IV. Changes in the Annual Update of the LTCH PPS

    In existing regulations at Sec.  412.535 that were issued in the 
August 30, 2002, final rule, we specify a schedule for publishing 
information on the LTCH PPS on or before August 1, which coincided with 
the statutorily mandated publication schedule for the IPPS. In the 
March 7, 2003, proposed rule, we proposed to revise Sec.  412.535 to 
provide generally for a change in the annual rate update for the LTCH 
PPS, starting on July 1.
    Section 1886(e)(5)(A) of the Act requires that, for the IPPS, the 
proposed rule be published in the Federal Register ``not later than the 
April 1 before each fiscal year; and the final rule, not later than the 
August 1 before such fiscal year.'' The statute imposes no such 
publication schedule for the LTCH PPS. In the August 30, 2002, final 
rule, we stated that we were considering changing the publication 
schedule of the LTCH PPS annual rulemaking cycle in order to avoid 
concurrent publication of annual rules for these two systems for 
purposes of administrative feasibility and efficiency (67 FR 55977). In 
considering a change in the publication schedule of the LTCH PPS final 
rule, we contemplated a change in the effective date for updating the 
Federal rates for the LTCH PPS. Therefore, in the March 7, 2003, 
proposed rule, we proposed changing the effective date of the annual 
update for the LTCH PPS from October 1 to July 1 of each year in order 
to facilitate a timely publication of these two significant payment 
updates (IPPS and LTCH PPS). Thus, the annual update of the LTCH PPS 
Federal rates would no longer be linked to the start of the Federal 
fiscal year, as is the update of the IPPS. We had proposed that this 
change would necessitate publication of the final rule for the

[[Page 34126]]

LTCH PPS by no later than June 1 of each year (proposed revised Sec.  
412.535).
    In the March 7, 2003, proposed rule, we also proposed to amend 
Sec.  412.503 to include a definition of ``LTCH PPS rate year''. A 
``LTCH PPS rate year'' would mean the 12-month period of July 1 through 
June 30. In the proposed rule, we stated that we would use this period 
for those calculations related to updating the Federal rate for 
payments under the LTCH PPS. We also stated that the determination of 
the proposed fixed-loss threshold for outlier payment calculations, 
under Sec.  412.525(a), would also be calculated based on the LTCH PPS 
rate year. (Section VII.C. of this final rule includes a more detailed 
discussion of our outlier policy.)
    Proposing a change for the annual Federal rate update period for 
the LTCH PPS also necessitated a proposed recalculation of the excluded 
hospital market basket with capital estimate for the proposed 
forthcoming payment year, July 1, 2003, through June 30, 2004. In the 
August 30, 2002, final rule, we established a Federal rate of $34,956 
that was computed based on the excluded hospital with capital market 
basket calculated for the 12-month Federal fiscal year of October 1, 
2002, through September 30, 2003. As already noted, we proposed to 
change the Federal rate update for the LTCH PPS from the Federal fiscal 
year to a 12-month LTCH PPS rate year of July 1 through June 30, and 
the proposed rates in the March 7, 2003, proposed rule were based on 
this period. Because the Federal rate of $34,956 was originally 
computed based on a 12-month year, but in actuality will only be used 
for 9 months, if the proposed change in the LTCH PPS rate update year 
was finalized, we proposed, in the March 7, 2003, proposed rule, to 
make a budget neutral adjustment to the market basket update taking 
this 3-month differential into account in setting the Federal rate for 
July 1, 2003, through June 30, 2004. In addition, we proposed that the 
change in the 2004 LTCH PPS rate year would be budget neutral. In 
section VII.B.1 of this final rule, we describe this adjustment in 
greater detail.
    In the March 7, 2003, proposed rule, we proposed to update the LTCH 
PPS wage index that adjusts for differences in area wages under Sec.  
412.525(c) using the FY 1999 IPPS wage data because these are the best 
available wage data (as discussed in section VII.C. of this preamble).
    We also stated that we were proposing to recalculate the budget 
neutrality offset to account for the effect of the transition period 
and the policy allowing LTCHs to elect 100 percent Federal rate 
payments rather than the transition blend.
    We also proposed an updated fixed-loss amount for determining 
outlier payments based on the updated proposed Federal rate (as 
discussed in section VII. of this preamble).
    In section IV.C. of the March 7, 2003, proposed rule, we stated 
that we did not propose an update to the LTC-DRG classifications or 
relative weights at this time. Currently, the LTC-DRG patient 
classifications used by the LTCH PPS for FY 2003 are based directly on 
the same version of DRGs used by the IPPS, that is, GROUPER 20.0. 
Therefore, we did not propose any change to the timing of the annual 
update of the LTC-DRG classifications and relative weights. They will 
remain linked to the annual adjustments of the acute care hospital 
inpatient DRG system, which are based on the annual revisions to the 
ICD-9-CM codes, effective each October 1. Table 3 of the Addendum to 
the August 30, 2002, final rule (67 FR 56076-56084), which were 
reprinted as Table 3 of the Addendum to the March 7, 2003, proposed 
rule, contains the LTC-DRG classifications and relative weights that we 
proposed to continue to apply to discharges occurring during the period 
of July 1, 2003, through September 30, 2003. As an aid in calculating 
payment under the short-stay outlier policy, under Sec.  412.529, we 
also are including, in column 3 of Table 3, the proposed five-sixths 
average length of stay that will be applied to each LTC-DRG in 
determining whether the LTCH stay is a short-stay outlier. The average 
length of stay for each DRG based on the FY 2001 MedPAR data, which 
were used for the FY 2003 LTCH PPS final rule, are still the best 
available complete LTCH discharge data available at this time.
    The revised LTC-DRG classifications and relative weights for 
discharges occurring from October 1, 2003, through September 30, 2004, 
for payments under the LTCH PPS during that period would continue to be 
updated on a Federal fiscal year cycle as is the case for the acute 
care hospital inpatient DRG system. The FY 2004 DRGs and relative 
weights for the IPPS had not yet been proposed by the time the March 7, 
2003, proposed rule was published and we were unable to propose updated 
LTC-DRGs and relative weights (which would be based on the proposed 
updated acute care hospital inpatient DRGs). Thus, we proposed that the 
LTC-DRG classifications and relative weights would be presented for 
public comment in the proposed rule for the IPPS and finalized in the 
IPPS final rule, with an effective date of October 1, 2003.
    The proposed change in the LTCH PPS rate year for the LTCH PPS from 
October 1 through September 30 to July 1 through June 30 means that, 
although the Federal rate calculations in the August 30, 2002, final 
rule were based on a 12-month year, only 9 months will elapse before 
the July 1, 2003, update. In the March 7, 2003, proposed rule, we 
proposed to make a prospective adjustment to the market basket update 
to take into account this 3-month differential in setting the rates for 
July 1, 2003, through June 30, 2004.
    Specifically, we explained that the proposed updates for the 
proposed 2004 LTCH PPS rate year would be affected as follows:
    [sbull] The proposed update to the standard Federal rate calculated 
in accordance with Sec.  412.523(c)(3) would be adjusted to account for 
updating the standard Federal rate on July 1, 2003, instead of October 
1, 2003.
    [sbull] The fixed-loss amount for determining high-cost outlier 
payments under Sec.  412.525(a) would also be updated based on the 
Federal rate effective for July 1, 2003, through June 30, 2004.
    In section VI.B.1 of the March 7, 2003, proposed rule, we discussed 
the proposed computational adjustments resulting from our proposed 
establishment of a LTCH PPS rate year beginning July 1, 2003, through 
June 30, 2004.
    In the March 7, 2003, proposed rule, we stated that several 
provisions of the LTCH PPS would not be affected by the change in the 
annual rate update year for the LTCH PPS from October 1 to July 1 
because these policies are not based on any of the Federal rate 
calculations for the LTCH PPS. Specifically, the following provisions 
would not be affected:
    [sbull] The transition blends provided for under Sec.  412.533(a) 
will not be affected because they are linked to the start of each 
LTCH's cost reporting period, rather than to the start of the Federal 
fiscal year. (LTCHs being paid under the transition blend methodology 
will receive those blends for the entire 5-year transition period, 
unless they elect payments based on 100 percent of the Federal rate.) 
For instance, for cost reporting periods that began on or after October 
1, 2002, and before October 1, 2003, the total payment for a LTCH is 80 
percent of the amount that will be calculated under the reasonable 
cost-based payment system for that specific LTCH and 20 percent of the 
Federal prospective payment amount. For cost reporting periods 
beginning on or after October 1, 2003, and before October 1, 2004, the 
total payment for a LTCH is

[[Page 34127]]

60 percent of the amount that will be calculated under the reasonable 
cost-based payment system for that specific LTCH and 40 percent of the 
Federal prospective payment amount.
    [sbull] The 5-year phase-in of the adjustment for differences in 
area wage levels under Sec.  412.525(c) will not be affected because 
they are linked to the start of each LTCH's cost reporting period, 
rather than to the start of the Federal fiscal year. For cost reporting 
periods that began on or after October 1, 2002, and before September 
30, 2003, the applicable LTCH PPS wage index is one-fifth of the full 
LTCH wage index value, and for cost reporting periods beginning on or 
after October 1, 2003, and before September 30, 2004, the applicable 
LTCH PPS wage index is two-fifths of the full LTCH wage index value.
    [sbull] The LTC-DRGs and their relative weights and the GROUPER 
will not be affected since they will continue to be updated effective 
October 1 through September 30 each year based on the changes to the 
DRGs published in the IPPS final rule.
    We received eight comments regarding our proposal to change the 
effective date of the annual update for the LTCH PPS from October 1 to 
July 1 of each year.
    Comment: Two commenters supported the establishment of the LTCH PPS 
rate year, but suggested that publishing the final rule each year by 
May 1, rather than by June 1 would allow LTCHs additional time for 
adjustments to their payment systems.
    Response: We thank the commenters for endorsing the establishment 
of the revised LTCH PPS rate year. In changing the effective date of 
the LTCH PPS rate year update and the resulting publication dates of 
the proposed and final regulations for the system, we stated that this 
shift in the schedule would promote ``administrative feasibility and 
efficiency,'' by avoiding concurrent rulemaking and publishing with the 
IPPS final rule. As we have already noted, section 1886(e)(5)(A) of the 
Act requires that, for the IPPS, the proposed rule be published in the 
Federal Register ``not later than the April 1 before each fiscal year; 
and the final rule, not later than the August 1 before such fiscal 
year,'' but no similar requirement is imposed on the LTCH PPS.
    Publishing a final rule annually by May 1 in order to allow 60-days 
between publication and effective date of the LTCH PPS rate update does 
not invalidate our stated objectives. Therefore, we will revise the 
regulations to require publication of the final LTCH rule by May 1 of 
each year unless for ``good cause'' we are unable to publish by that 
date, but before June 1. (We note that ``good cause'' used in this 
context is not coextensive and is broader than the ``good cause'' 
standard used in the Administrative Procedures Act (A.P.A.) at 5 U.S.C. 
section 553(d)(3).)
    Comment: Several commenters took issue with the proposed change in 
the effective date of the annual update for the LTCH PPS from October 1 
to July 1 of each year while still retaining the October 1 effective 
date for updating LTC-DRG classifications and weights. They believe 
that this policy change will be burdensome to LTCHs, requiring two 
separate updates during one cost reporting period as well as increased 
systems costs. These commenters urged us to remain with the existing 
update and publication schedule and some suggested deferring the change 
until full implementation of the LTCH PPS in FY 2006. One commenter 
raised the issue that this ``fragmentary'' implementation of individual 
updates will increase potential payment calculation errors for LTCHs. 
Another commenter urged us to pay LTCHs as a ``pass through'' for any 
expenses that they incur in complying with the new regulations, should 
they be made final.
    One commenter stated that administrative feasibility and efficiency 
at CMS did not justify burdening LTCHs in this manner. One of the 
commenters asserted that the costs for updating LTCH billing systems to 
accommodate this change in the LTCH PPS rate year will have a 
considerable impact on LTCHs as Small Businesses and, therefore, should 
have been reviewed under the A.P.A and the Regulatory Flexibility Act 
(RFA).
    Response: In response to these commenters, we first want to 
establish the fact that we have no requirement that LTCHs maintain 
payment systems or coding software in order to be paid under the LTCH 
PPS. We understand that it is common for many hospitals, consultants, 
and industry associations to do so, but we believe that some of the 
commenters who oppose the proposed change in the LTCH PPS rate year for 
the LTCH PPS to July 1 through June 30 while retaining October 1 
through September 30 for the LTC-DRG update are oversimplifying what 
presently exists from a systems standpoint. Currently, all providers 
with cost reporting periods beginning in any month other than October 
already are subject to two separate updates. In addition, rate changes 
may occur during the fiscal year because of Congressional action for 
services rendered ``on or after'' the date that the rate change was 
effective. Additionally, ongoing audit and review procedures, provider-
generated appeals procedures, and either administrative or judicial 
decisions also can produce hospital-level rate changes not associated 
with the start of a Federal fiscal year.
    As noted above, we do not require providers to process claims or to 
determine LTC-DRG assignments, but should a LTCH or any other group 
choose to duplicate the PRICER software that is required for fiscal 
intermediaries, or the GROUPER software that we use, it is an 
individual business determination.
    We primarily want to remind the commenters that the determination 
of Medicare payments based on submitted claims is solely a 
responsibility of each fiscal intermediary. Since payments to LTCHs 
will be based on claims processing done by fiscal intermediaries, we do 
not understand one commenter's assertion that we should not implement 
this policy because one of the payment consequences in establishing the 
LTCH PPS rate year will be to cause potential calculation errors by 
LTCHs.
    Nowhere in our regulations are LTCHs required to maintain the 
systems capability to calculate payments. Therefore, although 
individual LTCHs and other groups may elect, for their own purposes, to 
purchase software packages in order to duplicate work done by our 
contractors, we do not agree that those costs should be paid as a pass-
through by us. Moreover, we continue to believe that since the start of 
cost reporting periods for many LTCHs, as well as acute care hospitals, 
have not generally coincided with the October starting date of the 
Federal fiscal year, those hospitals that choose to have their own 
payment software are very familiar with the virtually seamless routine 
of inputting new numbers to their existing systems when a final rule is 
published. We do not believe that this policy will be unduly burdensome 
to such LTCHs. We also point out to the commenters that with 
publication of the proposed rule on March 7, 2003, we have complied 
with the A.P.A. As to the RFA, as stated in the proposed rule (68 FR 
11259), this rule would not have a significant impact on small entities 
(this includes small businesses).
    In response to the two comments suggesting that we delay 
implementation of this policy until full phase-in of the LTCH PPS in FY 
2006, based on our evaluation of the above comments, we do not believe 
that such a decision is warranted.
    Comment: One commenter suggested that if we found it necessary to

[[Page 34128]]

reschedule the effective date and publication cycle of one of the post-
acute care prospective payment systems, we should do so for Home Health 
Agency (HHA) or Skilled Nursing Facilities (SNF) which are not DRG-
based, and, therefore, not linked to the October 1 update.
    Response: As we have noted elsewhere in this final rule, there is 
no statutory authority requiring the update of the LTCH PPS to coincide 
with the October 1 start of the Federal fiscal year. On the contrary, 
annual updates linked to the October 1 start of the Federal fiscal year 
are required for both the SNF PPS, under section 1888(e)(4)(H) of the 
Act (implemented in Sec.  413.345), and the HHA PPS, under section 
1895(b)(3)(B) (implemented in Sec.  484.225). Therefore, although we do 
not have the authority to shift the annual update for the SNF PPS or 
the HHA PPS, we believe that such a policy is appropriate under section 
123 of Public Law 106-113 and section 307(b) of Public Law 106-554, 
which conferred broad authority on the Secretary in designing and 
implementing a PPS for LTCHs.
    Comment: One commenter noted that ``the use of two GROUPERs will 
not in and of itself create any hardship on LTCHs [which] will be able 
to adapt to this process. Most hospitals today do not have fiscal years 
that coincide with the federal (sic) fiscal year and must adapt to the 
use of two GROUPERs during their cost reporting year.'' This commenter 
did express concern, however, about the additional rate changes caused 
by the cost report reconciliation if the proposed outlier policy was 
finalized. The commenter suggested that we require fiscal 
intermediaries to update cost to charge ratios either at July 1 or 
October 1 in order to limit the number of changes during a 12-month 
period of time.
    Response: We agree with the commenter's assessment of most LTCHs' 
(and acute care hospital's) ability to adapt to the use of two GROUPERs 
during one cost reporting period. Regarding rate changes brought about 
by changes in our outlier policy, as noted elsewhere in this final 
rule, all discussions of the outlier policy are presented in the IPPS 
high-cost outlier final rule.
    In this final rule, we amend Sec.  412.535 to indicate that 
information on the unadjusted Federal payment rates and a description 
of the methodology and data used to calculate the payment rates under 
the LTCH PPS will be published in the Federal Register on or before May 
1 prior to the beginning of each LTCH PPS rate year beginning July 1, 
unless for good cause we are unable to make the May 1 publication date, 
but before June 1. We proposed that information on the DRG 
classification system and associated weighting factors, with the DRGs 
from which the LTC-DRGs are derived, would be published in the proposed 
IPPS rule and, ultimately, the final rule for the IPPS (the final IPPS 
rule is published on or before August 1 of each Federal fiscal year). 
Section XIV. of this final rule contains an impact analysis that 
reflects the impact of these changes.

V. Changes in Long-Term Care Diagnosis-Related Group (LTC-DRG) 
Classifications and Relative Weights

A. Background

    Section 123 of Public Law 106-113 specifically requires that the 
PPS for LTCHs be a per discharge system with a DRG-based patient 
classification system reflecting the differences in patient resources 
and costs in LTCHs while maintaining budget neutrality. Section 
307(b)(1) of Public Law 106-554 modified the requirements of section 
123 of Public Law 106-113 by specifically requiring that the Secretary 
examine ``the feasibility and the impact of basing payment under such a 
system [the LTCH PPS] on the use of existing (or refined) hospital 
diagnosis-related groups (DRGs) that have been modified to account for 
different resource use of long-term care hospital patients as well as 
the use of the most recently available hospital discharge data.''
    In accordance with section 307(b)(1) of Public Law 106-554 and 
Sec.  412.515 of our existing regulations, the LTCH PPS uses 
information from LTCH patient records to classify patient cases into 
distinct long-term care diagnosis-related groups (LTC-DRGs) based on 
clinical characteristics and expected resource needs. The LTC-DRGs used 
as the patient classification component of the LTCH PPS correspond to 
the DRGs in the IPPS. We apply weights to the existing hospital 
inpatient DRGs to account for the difference in resource use by 
patients exhibiting the case complexity and multiple medical problems 
characteristic of LTCHs.
    In a departure from the IPPS, we use low volume LTC-DRGs (less than 
25 LTCH cases) in determining the LTC-DRG weights, since LTCHs do not 
typically treat the full range of diagnoses as do acute care hospitals. 
In order to deal with the large number of low volume DRGs (all DRGs 
with fewer than 25 cases), we group low volume DRGs into 5 quintiles 
based on average charge per discharge. (A listing of the composition of 
low volume quintiles appears in the August 30, 2002, final rule at 67 
FR 55986.) We also take into account adjustments to payments for cases 
in which the stay at the LTCH is five-sixths of the geometric average 
length of stay and classify these cases as short-stay outlier cases. (A 
detailed discussion of the application of the Lewin Group model that 
was used to develop the LTC-DRGs appears in the August 30, 2002, final 
rule at 67 FR 55978.)

B. Patient Classifications Into DRGs

    Generally, under the LTCH PPS, Medicare payment is made at a 
predetermined specific rate for each discharge; that payment varies by 
the LTC-DRG to which a beneficiary's stay is assigned. Cases are 
classified into LTC-DRGs for payment based on the following six data 
elements:
    (1) Principal diagnosis.
    (2) Up to eight additional diagnoses.
    (3) Up to six procedures performed.
    (4) Age.
    (5) Sex.
    (6) Discharge status of the patient.
    Upon the discharge of the patient from a LTCH, the LTCH must assign 
appropriate diagnosis and procedure codes from the ICD-9-CM. As of 
October 16, 2002, a LTCH that was required to comply with the HIPAA 
Administrative Simplification Standards and that had not obtained an 
extension in compliance with the Administrative Compliance Act (Pub. L. 
107-105) is obligated to comply with the standards at 45 CFR 162.1002 
and 45 CFR 162.1102. Completed claim forms are to be submitted to the 
LTCH's Medicare fiscal intermediary.
    Medicare fiscal intermediaries enter the clinical and demographic 
information into their claims processing systems and subject this 
information to a series of automated screening processes called the 
Medicare Code Editor (MCE). These screens are designed to identify 
cases that require further review before assignment into a DRG can be 
made. During this process, the following type of cases are selected for 
further development:
    [sbull] Cases that are improperly coded. (For example, diagnoses 
are shown that are inappropriate, given the sex of the patient. Code 
68.6, Radical abdominal hysterectomy, would be an inappropriate code 
for a male.)
    [sbull] Cases including surgical procedures not covered under 
Medicare. (For example, organ transplant in a nonapproved transplant 
center.)
    [sbull] Cases requiring more information. (For example, ICD-9-CM 
codes are required to be entered at their highest level of specificity. 
There are valid 3-digit, 4-digit, and 5-digit codes. That is,

[[Page 34129]]

code 136.3, Pneumocystosis, contains all appropriate digits, but if it 
is reported with either fewer or more than 4 digits, the claim will be 
rejected by the MCE as invalid.)
    [sbull] Cases with principal diagnoses that do not usually justify 
admission to the hospital. (For example, code 437.9, Unspecified 
cerebrovascular disease. While this code is valid according to the ICD-
9-CM coding scheme, a more precise code should be used for the 
principal diagnosis.)
    After screening through the MCE, each claim will be classified into 
the appropriate LTC-DRG by the Medicare LTCH GROUPER. The LTCH GROUPER 
is specialized computer software based on the same GROUPER used by the 
IPPS. The GROUPER software was developed as a means of classifying each 
case into a DRG on the basis of diagnosis and procedure codes and other 
demographic information (age, sex, and discharge status). Following the 
LTC-DRG assignment, the Medicare fiscal intermediary will determine the 
prospective payment by using the Medicare PRICER program, which 
accounts for hospital-specific adjustments. As provided for under the 
IPPS, we provide an opportunity for the LTCH to review the LTC-DRG 
assignments made by the fiscal intermediary and to submit additional 
information within a specified timeframe (Sec.  412.513(c)).
    The GROUPER is used both to classify past cases in order to measure 
relative hospital resource consumption to establish the DRG weights and 
to classify current cases for purposes of determining payment. The 
records for all Medicare hospital inpatient discharges are maintained 
in the MedPAR file. The data in this file are used to evaluate possible 
DRG classification changes and to recalibrate the DRG weights during 
our annual update. DRG weights are based on data for the population of 
LTCH discharges, reflecting the fact that LTCH patients represent a 
different patient mix than patients in short-term acute care hospitals.

C. Organization of DRGs

    The DRGs are organized into 25 Major Diagnostic Categories (MDCs), 
most of which are based on a particular organ system of the body; the 
remainder involve multiple organ systems (such as MDC 22, Burns). 
Accordingly, the principal diagnosis determines MDC assignment. Within 
most MDCs, cases are then divided into surgical DRGs and medical DRGs. 
Surgical DRGs are assigned based on a surgical hierarchy that orders 
operating room (O.R.) procedures or groups of O.R. procedures by 
resource intensity. The GROUPER does not recognize all ICD-9-CM 
procedure codes as procedures that affect DRG assignment, that is, 
procedures which are not surgical (for example, EKG), or minor surgical 
procedures (for example, 86.11, Biopsy of skin and subcutaneous 
tissue).
    The medical DRGs are generally differentiated on the basis of 
diagnosis. Both medical and surgical DRGs may be further differentiated 
based on age, sex, discharge status, and presence or absence of 
complications or comorbidities (CC). We note that CCs are defined by 
certain secondary diagnoses not related to, or not inherently a part 
of, the disease process identified by the principal diagnosis. (For 
example, the GROUPER would not recognize a code from the 800.0x series, 
Skull fracture, as a CC when combined with principal diagnosis 850.4, 
Concussion with prolonged loss of consciousness, without return to 
preexisting conscious level.) In addition, we note that the presence of 
additional diagnoses does not automatically generate a CC, as not all 
DRGs recognize a comorbid or complicating condition in their 
definition. (For example, DRG 466, Aftercare without History of 
Malignancy as Secondary Diagnosis, is based solely on the principal 
diagnosis, without consideration of additional diagnoses for DRG 
determination.)
    In its June 2000 Report to Congress, MedPAC recommended that the 
Secretary ``* * * improve the hospital inpatient prospective payment 
system by adopting, as soon as practicable, diagnosis-related group 
refinements that more fully capture differences in severity of illness 
among patients.'' (Recommendation 3A, p. 63) We have determined it is 
not practical at this time to develop a refinement to inpatient 
hospital DRGs based on severity due to time and resource requirements. 
However, this does not preclude us from development of a severity-
adjusted DRG refinement in the future. That is, a refinement to the 
list of comorbidities and complications could be incorporated into the 
existing DRG structure. It is also possible a more comprehensive 
severity adjusted structure may be created if a new code set is 
adopted. That is, if ICD-9-CM is replaced by ICD-10-CM (for diagnostic 
coding) and ICD-10-PCS (for procedure coding) or by other code sets, a 
severity concept may be built into the resulting DRG assignments. Of 
course any change to the code set would be adopted through the process 
established in the HIPAA Administrative Simplification provisions.

D. Update of LTC-DRGs

    For FY 2003, the LTC-DRG patient classification system was based on 
LTCH data from the FY 2001 MedPAR file, which contained hospital bills 
received through March 31, 2001, for hospital discharges occurring in 
FY 2001. The patient classification system consisted of 510 DRGs that 
formed the basis of the FY 2003 LTCH PPS GROUPER. The 510 LTC-DRGs 
included two ``error DRGs''. As in the IPPS, we included two error DRGs 
in which cases that cannot be assigned to valid DRGs will be grouped. 
These two error DRGs are DRG 469 (Principal Diagnosis Invalid as a 
Discharge Diagnosis) and DRG 470 (Ungroupable). (See the August 1, 
2001, Medicare Program final rule, Changes to the Hospital Inpatient 
Prospective Payment Systems and Rates and Costs of Graduate Medical 
Education; Fiscal Year 2002 Rates (66 FR 40062).) The other 508 LTC-
DRGs are the same DRGs used in the IPPS GROUPER for FY 2003 (Version 
20.0).
    In the health care industry, annual changes to the ICD-9-CM codes 
are effective for discharges occurring on or after October 1 each year. 
Thus, the manual and electronic versions of the GROUPER software, which 
are based on the ICD-9-CM codes, are also revised annually and 
effective for discharges occurring on or after October 1 each year. As 
discussed earlier, the patient classification system for the LTCH PPS 
(LTC-DRGs) is based on the IPPS patient classification system (CMS-
DRGs), which is updated annually and effective for discharges occurring 
on or after October 1 through September 30 each year. The updated DRGs 
and GROUPER software are based on the latest revision to the ICD-9-CM 
codes, which are published annually in the IPPS proposed rule and final 
rule. The new or revised ICD-9-CM codes are not used by the industry 
for either the IPPS or the LTCH PPS until the beginning of the next 
Federal fiscal year (effective for discharges occurring on or after 
October 1 through September 30). (The use of the ICD-9-CM codes in this 
manner is consistent with current usage and the HIPAA regulations.) 
October 1 is also when the changes to the CMS-DRGs and the next version 
of the GROUPER software becomes effective.
    As indicated previously in the March 7, 2003, proposed rule, we 
proposed to make the annual update to the LTCH PPS effective from July 
1 through June 30 each year. As a result of this change, we proposed 
that the LTCH PPS would

[[Page 34130]]

use two GROUPERS during the course of a 12-month period: One GROUPER 
for 3 months (from July 1 through September 30); and an updated GROUPER 
for 9 months (from October 1 through June 30). The need to use two 
GROUPERs is based upon the October 1 effective date of the updated ICD-
9-CM coding system. As previously discussed, new ICD-9-CM codes may 
result in changes to the structure of the DRGs. In order for the 
industry to be on the same schedule (for both the IPPS and the LTCH 
PPS) for the use of the most current ICD-9-CM codes, it was necessary 
for us to propose to apply two GROUPER programs to the LTCH PPS. 
Although we did not believe that this would have any adverse effect on 
LTCHs, we were interested in receiving comments on this issue. LTCHs 
would continue to code diagnosis and procedures using the most current 
version of the ICD-9-CM coding system.
    Currently, for Federal FY 2003, we are using Version 20.0 of the 
GROUPER software for both the IPPS and the LTCH PPS. For discharges 
beginning on October 1, 2003 (Federal FY 2004), in the March 7, 2003, 
LTCH PPS proposed rule, we proposed to use Version 21.0 of the GROUPER 
software for both the IPPS and the LTCH PPS. Thus, changes to the CMS-
DRGs (the DRGs on which the LTC-DRGs are based), and their relative 
weights, as well as the LTC-DRGs and their relative weights that will 
be effective for October 1, 2003, through September 30, 2004, are 
presented in the IPPS FY 2004 proposed rule that was published on May 
19, 2003, in the Federal Register (68 FR 27154). Accordingly, we will 
notify LTCHs of any revised LTC-DRG relative weights based on the final 
DRGs and Version 21.0 GROUPER for the IPPS that would be effective 
October 1, 2003.
    Comment: Two commenters suggested that we synchronize the LTCH rate 
year (that is, July 1 through June 30) with the update of the LTC DRGs 
which occurs on October 1 by delaying the October 1 update until the 
following July 1. As an alternative, one commenter suggested that the 
LTCHs could continue to use the LTC-DRG weights determined the previous 
October 1 until the start of the next LTCH rate year (July 1, 2004), 
and conduct a readjustment for the LTCH PPS on July 1 of the following 
year.
    Response: With regard to the commenters' suggestion to continue to 
use the current ICD-9-CM and DRG Grouper Version 20 until June 30, 
2004, delaying the update until the following year, we believe that 
this suggestion is not feasible. This would require coders to use two 
different ICD-9-CM versions, one for IPPS use (Version 21 will be 
implemented October 1, 2003) and another for LTCH PPS. Moreover, the 
HIPPA (45 CFR part 162) requires that the ICD-9-CM be the standard 
medical code set and each code set is valid within the dates specified 
by the organization (Department of Health and Human Services) 
responsible for maintaining that code set. The use of other than the 
current code set (most recent update to the ICD-9-CM will be effective 
October 1, 2003) would be in direct violation of the current HIPPA 
requirements.
    In this final rule, while we are adopting the proposed use of two 
GROUPER software programs over the course of the LTCH rate year, one 
GROUPER for 3 months (from July 1 through September 30); and an updated 
GROUPER for 9 months (from October 1 through June 30), the existing 
GROUPER and the updated GROUPER will be in effect for 12 months. These 
two GROUPER programs will be the same programs in use for the IPPS.

E. ICD-9-CM Coding System

1. Uniform Hospital Discharge Data Set (UHDDS) Definitions
    Because the assignment of a case to a particular LTC-DRG will help 
determine the amount that will be paid for the case, it is important 
that the coding is accurate. Classifications and terminology used in 
the LTCH PPS are consistent with the ICD-9-CM and the UHDDS, as 
recommended to the Secretary by the National Committee on Vital and 
Health Statistics (``Uniform Hospital Discharge Data: Minimum Data Set, 
National Center for Health Statistics, April 1980'') and as revised in 
1984 by the Health Information Policy Council (HIPC) of the U.S. 
Department of Health and Human Services.
    We wish to point out that the ICD-9-CM coding terminology and the 
definitions of principal and other diagnoses of the UHDDS are 
consistent with the requirements of the HIPPA Administrative 
Simplification Act of 1996 (45 CFR part 162). Furthermore, the UHDDS 
has been used as a standard for the development of policies and 
programs related to hospital discharge statistics by both governmental 
and nongovernmental sectors for over 30 years. In addition, the 
following definitions (as described in the 1984 Revision of the UHDDS, 
approved by the Secretary of Health and Human Services for use starting 
January 1986) are requirements of the ICD-9-CM coding system, and have 
been used as a standard for the development of the CMS-DRGs:
    [sbull] Diagnoses include all diagnoses that affect the current 
hospital stay.
    [sbull] Principal diagnosis is defined as the condition established 
after study to be chiefly responsible for occasioning the admission of 
the patient to the hospital for care.
    [sbull] Other diagnoses (also called secondary diagnoses or 
additional diagnoses) are defined as all conditions that coexist at the 
time of admission, that develop subsequently, or that affect the 
treatment received or the length of stay or both. Diagnoses that relate 
to an earlier episode of care that have no bearing on the current 
hospital stay are excluded.
    [sbull] All procedures performed will be reported. This includes 
those that are surgical in nature, carry a procedural risk, carry an 
anesthetic risk, or require specialized training.
    We provide LTCHs with a 60-day window after the date of the notice 
of the initial LTC-DRG assignment to request review of that assignment. 
Additional information may be provided by the LTCH to the fiscal 
intermediary as part of that review.
2. Maintenance of the ICD-9-CM Coding System
    The ICD-9-CM Coordination and Maintenance (C&M) Committee is a 
Federal interdepartmental committee, co-chaired by the National Center 
for Health Statistics (NCHS) and CMS, that is charged with maintaining 
and updating the ICD-9-CM system. The C&M Committee is jointly 
responsible for approving coding changes, and developing errata, 
addenda, and other modifications to the ICD-9-CM to reflect newly 
developed procedures and technologies and newly identified diseases. 
The C&M Committee is also responsible for promoting the use of Federal 
and non-Federal educational programs and other communication techniques 
with a view toward standardizing coding applications and upgrading the 
quality of the classification system.
    The NCHS has lead responsibility for the ICD-9-CM diagnosis codes 
included in the Tabular List and Alphabetic Index for Diseases, while 
CMS has lead responsibility for the ICD-9-CM procedure codes included 
in the Tabular List and Alphabetic Index for Procedures.
    The C&M Committee encourages participation by health-related 
organizations in the above process and holds public meetings for 
discussion of educational issues and proposed coding changes twice a 
year at the CMS Central Office located in Baltimore, Maryland. The 
agenda and dates of the meetings

[[Page 34131]]

can be accessed on the CMS Web site at: http://www.cms.gov/paymentsystems/icd9
.
    All changes to the ICD-9-CM coding system affecting DRG assignment 
are addressed annually in the IPPS proposed and final rules. Because 
the DRG-based patient classification system for the LTCH PPS is based 
on the IPPS DRGs, these changes will also affect the LTCH PPS LTC-DRG 
patient classification system.
    As discussed above, the ICD-9-CM coding changes that have been 
adopted by the C&M Committee become effective at the beginning of each 
Federal fiscal year, October 1. Regardless of the change to the annual 
update of the LTCH PPS year to July 1, coders will use the most current 
updated ICD-9-CM coding book from October 1 through September 30 of 
each year. This means that coders and LTCHs that use the updated ICD-9-
CM coding system will be on the same schedule (effective October 1) as 
the rest of the health care industry. The newest version of ICD-9-CM is 
not available for use until October 1, which would be 4 months after 
the date that we will publish the LTCH annual payment rate update final 
rule. The new codes on which the LTC-DRGs are based will go into effect 
and be available for use for discharges occurring on or after October 1 
through September 30 of each year. This annual schedule of the revision 
to the ICD-9-CM coding system and the change of the ICD-9-CM coding 
books or electronic coding programs has been in effect since the 
adoption of Revision 9 of the ICD in 1979.
    Of particular note to LTCHs will be the invalid diagnosis codes 
(Table 6C) and the invalid procedure codes (Table 6D) located in the 
annual proposed and final rules for the IPPS. Claims with invalid codes 
will not be processed by the Medicare claims processing system.
3. Coding Rules and Use of ICD-9-CM Codes in LTCHs
    We emphasize the need for proper coding by LTCHs. Inappropriate 
coding of cases can adversely affect the uniformity of cases in each 
LTC-DRG and produce inappropriate weighting factors at recalibration. 
We continue to urge LTCHs to focus on improved coding practices. 
Because of concerns raised by LTCHs concerning correct coding, we have 
asked the American Hospital Association (AHA) to provide additional 
clarification or instruction on proper coding in the LTCH setting. The 
AHA will provide this instruction via their established process of 
addressing questions through their publication ``Coding Clinic for ICD-
9-CM''. Written questions or requests for clarification may be 
addressed to the Central Office on ICD-9-CM, American Hospital 
Association, One North Franklin, Chicago, IL 60606. A form for the 
question(s) is available to be downloaded and mailed on AHA's Web site 
at: www.ahacentraloffice.org. In addition, current coding guidelines 
are available at the National Center for Health Statistics (NCHS) Web 
site: www.cdc.gov/nchs.icd9.htm.
    In conjunction with the cooperating parties (AHA, AHIMA, and NCHS), 
we have reviewed actual medical records and are concerned about the 
quality of the documentation under the LTCH PPS, as was the case at the 
beginning of the IPPS. We fully believe that, with experience, the 
quality of the documentation and coding will improve, just as it did 
for the IPPS. As noted above, the cooperating parties have plans to 
assist their members with improvement in documentation and coding 
issues for the LTCHs through specific questions and coding guidelines. 
The importance of good documentation is emphasized in the revised ICD-
9-CM Official Guidelines for Coding and Reporting (October 1, 2002): 
``A joint effort between the attending physician and coder is essential 
to achieve complete and accurate documentation, code assignment, and 
reporting of diagnoses and procedures. The importance of consistent, 
complete documentation in the medical record cannot be overemphasized. 
Without such documentation, the application of all coding guidelines is 
a difficult, if not impossible, task. (Coding Clinic for ICD-9-CM, 
Fourth Quarter 2002, page 115).
    To improve medical record documentation, LTCHs should be aware that 
if the patient is being admitted for continuation of treatment of an 
acute or chronic condition, guidelines at section I.B.10 of the Coding 
Clinic for ICD-9-CM, Fourth Quarter 2002 (page 129) are applicable 
concerning selection of principal diagnosis. To clarify coding advice 
issued in the August 30, 2002 final rule (67 FR 55979-55981), we would 
like to point out that, at Guideline I.B.12, Late Effects, a late 
effect is considered to be the residual effect (condition produced) 
after the acute phase of an illness or injury has terminated (Coding 
Clinic for ICD-9-CM, Fourth Quarter 2002, page 129). We have received a 
question regarding whether a LTCH should report the ICD-9-CM code(s) 
for an unresolved acute condition instead of the code(s) for late 
effect of rehabilitation. Depending on the documentation in the medical 
record, either code could be appropriate in a LTCH. Since 
implementation of the LTCH PPS, our Medicare fiscal intermediaries have 
been conducting training and providing assistance to LTCHs in correct 
coding. We have also issued manuals containing procedures as well as 
coding instructions to LTCHs and fiscal intermediaries. We will 
continue to conduct such training and provide guidance on an as-needed 
basis. We also refer readers to the detailed discussion on correct 
coding practices in the August 30, 2002, final rule (67 FR 55979-
55981).
    Comment: Two commenters expressed their support for our adherence 
to the official ICD-9-CM coding guidelines.
    Response: We appreciate the commenters support and anticipate 
working closely with both the AHA and the AHIMA to increase awareness 
of proper documentation and correct coding in the LTCH setting.

F. Changes to the Method for Updating the LTC-DRG Relative Weights

    As discussed in the March 7, 2003, proposed rule, under the LTCH 
PPS, each LTCH will receive a payment that represents an appropriate 
amount for the efficient delivery of care to Medicare patients. The 
system must be able to account adequately for each LTCH's case-mix in 
order to ensure both fair distribution of Medicare payments and access 
to adequate care for those Medicare patients whose care is more costly. 
Therefore, in accordance with Sec.  412.523(c), we adjust the standard 
Federal PPS rate by the LTC-DRG relative weights in determining payment 
to LTCHs for each case.
    Under this payment system, relative weights for each LTC-DRG are a 
primary element used to account for the variations in cost per 
discharge and resource utilization among the payment groups (Sec.  
412.515). To ensure that Medicare patients who are classified to each 
LTC-DRG have access to an appropriate level of services and to 
encourage efficiency, we calculate a relative weight for each LTC-DRG 
that represents the resources needed by an average inpatient LTCH case 
in that LTC-DRG. For example, cases in a LTC-DRG with a relative weight 
of 2 will, on average, cost twice as much as cases in a LTC-DRG with a 
weight of 1.
    As we discussed in the August 30, 2002, final rule (67 FR 55984-
55995), the LTC-DRG relative weights effective under the LTCH PPS for 
Federal FY 2003 were calculated using the March 2002 update of FY 2001 
MedPAR data and Version 20.0 of the CMS GROUPER software. We use total 
days and total

[[Page 34132]]

charges in the calculation of the LTC-DRG relative weights.
    By nature, LTCHs often specialize in certain areas, such as 
ventilator-dependent patients and rehabilitation and wound care. Some 
case types (DRGs) may be treated, to a large extent, in hospitals that 
have, from a perspective of charges, relatively high (or low) charges. 
Such distribution of cases with relatively high (or low) charges in 
specific LTC-DRGs has the potential to inappropriately distort the 
measure of average charges. To account for the fact that cases may not 
be randomly distributed across LTCHs, we use a hospital-specific 
relative value method to calculate relative weights. We believe this 
method removes this hospital-specific source of bias in measuring 
average charges. Specifically, we reduce the impact of the variation in 
charges across providers on any particular LTC-DRG relative weight by 
converting each LTCH's charge for a case to a relative value based on 
that LTCH's average charge. (See the August 30, 2002, final rule (67 FR 
55985) for further information of the hospital-specific relative value 
methodology.)
    In order to account for LTC-DRGs with low volume (that is, with 
fewer than 25 LTCH cases), we grouped those low volume LTC-DRGs into 
one of five categories (quintiles) based on average charges, for the 
purposes of determining relative weights. For FY 2003 based on the FY 
2001 MedPAR data, we identified 161 LTC-DRGs that contained between 1 
and 24 cases. This list of low volume LTC-DRGs was then divided into 
one of the five low volume quintiles, each containing a minimum of 32 
LTC-DRGs (161/5 = 32 with 1 LTC-DRG as a remainder). Each of the low 
volume LTC-DRGs grouped to a specific quintile received the same 
relative weight and average length of stay using the formula applied to 
the regular LTC-DRGs (25 or more cases), as described below. (See the 
August 30, 2002, final rule (67 FR 55985-55988) for further explanation 
of the development and composition of each of the five low volume 
quintiles for FY 2003.)
    After grouping the cases in the appropriate LTC-DRG, we calculate 
the relative weights by first removing statistical outliers and cases 
with a length of stay of 7 days or less. Next, we adjust the number of 
cases in each LTC-DRG for the effect of short-stay outlier cases under 
Sec.  412.529. The short-stay adjusted discharges and corresponding 
charges were used to calculate ``relative adjusted weights'' in each 
LTC-DRG using the hospital-specific relative value method described 
above. (See the August 30, 2002, final rule (67 FR 55989-55995) for 
further details on the steps for calculating the LTC-DRG relative 
weights.)
    We also adjust the LTC-DRG relative weights to account for 
nonmonotonically increasing relative weights. That is, we make an 
adjustment if cases classified to the LTC-DRG ``with comorbidities 
(CCs)'' of a ``with CC''/``without CC'' pair had a lower average charge 
than the corresponding LTC-DRG ``without CCs'' by assigning the same 
weight to both LTC-DRGs in the ``with CC''/``without CC'' pair. (See 
August 30, 2002, 67 FR 55990-55991). In addition, of the 510 LTC-DRGs 
in the LTCH PPS for FY 2003, based on the FY 2001 MedPAR data, we 
identified 159 LTC-DRGs for which there were no LTCH cases in the 
database. That is, no patients who would have been classified to those 
DRGs were treated in LTCHs during FY 2001 and, therefore, no charge 
data were reported for those DRGs. Thus, in the process of determining 
the relative weights of LTC-DRGs, we were unable to determine weights 
for these 159 LTC-DRGs using the method described above. However, since 
patients with a number of the diagnoses under these LTC-DRGs may be 
treated at LTCHs beginning in FY 2003, we assigned relative weights to 
each of the 159 ``no volume'' LTC-DRGs based on clinical similarity and 
relative costliness to one of the remaining 351 (510-159 = 351) LTC-
DRGs for which we were able to determine relative weights, based on the 
FY 2001 claims data. (A list of the no volume LTC-DRGs and further 
explanation of their relative weight assignment can be found in the 
August 30, 2002, final rule (67 FR 55991-55994).)
    Furthermore, we establish LTC-DRG relative weights of 0.0000 for 
heart, kidney, liver, lung, pancreas, and simultaneous pancreas/kidney 
transplants (LTC-DRGs 103, 302, 480, 495, 512 and 513, respectively) 
because Medicare will only cover these procedures if they are performed 
at a hospital that has been certified for the specific procedures by 
Medicare and presently no LTCH has been so certified. If in the future, 
however, a LTCH applies for certification as a Medicare-approved 
transplant center, we believe that the application and approval 
procedure would allow sufficient time for us to propose appropriate 
weights for the LTC-DRGs effected. At the present time, though, we only 
include these six transplant LTC-DRGs in the GROUPER program for 
administrative purposes because since the LTCH PPS uses the same 
GROUPER program for LTCHs as is used under the IPPS, removing these 
DRGs would be administratively burdensome.
    As we stated in the March 7, 2003, proposed rule, we proposed that 
we would continue to use the same LTC-DRGs and relative weights until 
October 1, 2003. Accordingly, Table 3 in the Addendum to the March 7, 
2003, proposed rule lists the LTC-DRGs and their respective relative 
weights and arithmetic mean length of stay that we proposed would 
continue to be used for the period of July 1, 2003, through September 
30, 2003. (This table is the same as Table 3 of the Addendum to the 
August 30, 2002, final rule (67 FR 56076-56084), except that it 
includes the proposed five-sixth of the average length of stay for 
short-stay outliers under Sec.  412.529.) As we noted in section IV.D. 
of the March 7, 2003, proposed rule, we proposed that the final DRGs 
and GROUPER for FY 2004 that will be used for the IPPS and the LTCH 
PPS, effective October 1, 2003, would be presented in the IPPS FY 2004 
final rule published no later than August 1, 2003, in the Federal 
Register.
    Accordingly, we will notify LTCHs of the revised LTC-DRG relative 
weights for use in determining payments for discharges occurring 
between October 1, 2003, and September 30, 2004, based on the final 
DRGs and Version 21.0 GROUPER published in the IPPS rule on or before 
August 1, 2003.

VI. Policy Change Related to Payments to LTCHs That Are Satellite 
Facilities

Provisions of the Proposed Rule

    In proposing the LTCH PPS (March 7, 2002, 67 FR 13416), we stated 
that we were considering proposing the elimination of the bed limit in 
Sec.  412.22(h)(2)(i) for pre-1997 excluded hospitals once the 
prospective payment system was fully phased-in and all payments were 
based on 100 percent of the Federal prospective payment rates. This 
statement generated a number of comments and in the August 30, 2002, 
final rule (67 FR 56012), we stated our agreement with commenters who 
urged us to adopt a policy eliminating the bed-number restrictions for 
pre-1997 LTCHs with satellite facilities, as soon as a LTCH is paid 
based on 100 percent of the Federal prospective rate. However, we also 
noted that we would address a change in the policy concerning bed 
limits in the next update of the LTCH PPS. Therefore, in the March 7, 
2003, proposed rule (68 FR 11243-11244), we proposed to eliminate the 
application of the bed-number restrictions set forth in Sec.  
412.22(h)(2)(i) for LTCHs established prior to 1997 with satellite 
facilities, effective at the start of the first cost

[[Page 34133]]

reporting year that a LTCH is paid under the 100 percent fully Federal 
prospective payment system. This will be either when a LTCH elects to 
be paid based on 100 percent of the Federal prospective rate or when 
the LTCH is fully transitioned to 100 percent of the Federal 
prospective rate, whichever comes first.
    Section 1886(b)(3) of the Act, as amended by section 4414 of Public 
Law 105-33, required existing LTCHs to be subject to caps on their 
target amounts for cost reporting periods beginning on or after October 
1, 1997, through September 30, 2002. For purposes of calculating these 
caps, the statute required the Secretary to ``estimate the 75th 
percentile of the target amounts for such hospitals within [each] class 
for cost reporting periods ending during fiscal year 1996.'' Section 
1886(b)(3)(H) of the Act, as amended by section 121 of Public Law 106-
113, directed the Secretary to provide for an appropriate wage 
adjustment to the caps on the target amounts for psychiatric and 
rehabilitation hospitals and units and LTCHs effective for cost 
reporting periods beginning on or after October 1, 1999 through 
September 30, 2002. In addition, payment limits were established for 
new excluded hospitals or units (excluding children's hospitals) 
effective October 1, 1997. For new excluded hospitals (that is, post-
1997 LTCHs), section 1886(b)(7) of the Act, as added by section 4416 of 
Public Law 105-33, specified that the payment amount for the facility's 
first two 12-month cost reporting periods, for which the hospital has a 
settled cost report, must not exceed 110 percent of the national median 
of target amounts of similarly classified hospitals for cost reporting 
periods ending during FY 1996, updated by the hospital market basket 
increase percentage to the first cost reporting period in which the 
hospital receives payment, as adjusted by section 1886(b)(7)(C) of the 
Act. The result of sections 4414 and 4416 of Public Law 105-33 was a 
distinction between the LTCHs established prior to, and those 
established after 1997, with lower payment caps for the post-1997 
LTCHs.
    In the July 30, 1999, IPPS final rule (64 FR 41532-41533), we 
promulgated regulations at Sec.  412.22(h)(2)(i) to discourage pre-1997 
excluded hospitals, which had the higher caps on target amounts as 
discussed above (under Sec.  413.40(c)(4)(iii)), from creating 
satellites rather than establishing new hospitals, in order to avoid 
the payment impact of the lower caps that apply to new hospitals (under 
Sec.  413.40(f)(2)(ii)). In the July 30, 1999, IPPS final rule (64 FR 
41490), we required that where a pre-1997 excluded hospital, such as a 
LTCH, established a satellite facility and, in doing so, its total 
beds, in both the parent hospital (or unit) and the satellite facility, 
exceeded the number of State-licensed and Medicare-certified beds in 
the parent hospital on the last day of its last cost reporting period 
beginning before October 1, 1997, the excluded hospital would be paid 
under the inpatient DRG system, instead of receiving payment as an 
excluded hospital under the reasonable cost-based payment system. 
Although the excluded hospital could ``transfer'' beds from the parent 
facility to the satellite, it could not increase its total bed capacity 
(at the parent and satellite(s)) beyond the level the hospital had in 
the most recent cost reporting period beginning before October 1, 1997, 
and still be paid as a hospital excluded from the IPPS. However, no 
such limitation was imposed on a LTCH established after October 1, 
1997. Since this type of hospital would have already been subject to 
the lower payment limit of 110 percent of the national median of target 
amounts for similarly classified hospitals under Sec.  
413.40(f)(2)(ii), it would not benefit by establishing a satellite 
facility instead of a separate free-standing hospital, as would a pre-
1997 LTCH.
    The rationale for applying the bed-limit provision only on pre-1997 
hospitals was the potential for gaming by those hospitals, by creating 
a satellite facility with a higher TEFRA target cap where, in reality, 
the satellite facility should have been a separately certified excluded 
facility, which would have been subject to the lower cap on payments to 
new (post-1997) facilities paid under the TEFRA system. Once the LTCH 
is paid based on 100 percent of the Federal prospective rate, however, 
the LTCH will no longer be subject to TEFRA caps and LTCH prospective 
payments will be the same regardless of when the LTCH was established. 
Therefore, consistent with the March 7, 2003, proposed rule, we are 
eliminating the bed-limit provision once a LTCH is paid based on 100 
percent of the LTCH Federal PPS rate. Finally, under this policy, the 
bed limitation on ``existing'' LTCHs will, however, continue to apply 
to those LTCHs while they are paid based on the transition blend, and, 
therefore, continue to receive a percentage of their payments based on 
the reasonable cost-based payment rules, until these hospitals are paid 
based on 100 percent of the Federal prospective payment rate.
    Comment: Several commenters expressed their strong support for our 
proposal to eliminate the bed number limitation for pre-1997 LTCHs with 
satellite facilities for those LTCHs receiving 100 percent of the 
Federal rate. One commenter recommended that the bed number limitation 
should also be eliminated for the IRFs since they are now receiving 
payment at 100 percent of the Federal rate.
    Response: We appreciate the strong endorsement in response to this 
proposed change. Regarding the commenter who recommended eliminating 
the bed size limitation for IRFs, we would suggest that the commenter 
look to the IRF proposed rule that was published on May 16, 2003 (68 FR 
26785).
    Accordingly, in this final rule, we are adopting the proposal to 
eliminate the bed size limitation for pre-1997 LTCHs with satellite 
facilities once the LTCH is paid at 100 percent of the Federal rate. We 
note that in the preamble to the March 7, 2003, proposed rule, we 
stated the two circumstances under which a LTCH would be paid based on 
100 percent of the Federal rate, which are for the start of the first 
cost reporting period that a LTCH elects fully Federal payment, as set 
forth in Sec.  412.533(c) or when the LTCH PPS is fully phased-in after 
the transition period. We inadvertently omitted the second circumstance 
in the proposed regulation text at Sec.  412.22(h)(6), therefore, we 
are revising that section to reflect this policy.

VII. Changes to the LTCH PPS Rates for the 2004 LTCH PPS Rate Year

A. Overview of the Development of the Payment Rates

    The LTCH PPS was effective for a LTCH's first cost reporting period 
beginning on or after October 1, 2002. Effective with that cost 
reporting period, LTCHs are paid, during a 5-year transition period, on 
the basis of an increasing proportion of the LTCH PPS Federal rate and 
a decreasing proportion of a hospital's payment under reasonable cost-
based payment system, unless the hospital makes a one-time election to 
receive payment based on 100 percent of the Federal rate (see Sec.  
412.533). New LTCHs (as defined at Sec.  412.23(e)(4)) are paid based 
on 100 percent of the Federal rate, with no phase-in transition 
payments.
    The basic methodology for determining LTCH PPS Federal prospective 
payment rates is set forth in the regulations at Sec. Sec.  412.515 
through 412.532. Below we discuss the proposed factors used to update 
the LTCH PPS standard Federal rate for the proposed 2004 LTCH PPS rate 
year published in

[[Page 34134]]

the March 7, 2003, proposed rule. We also discuss the factors used to 
establish the final update to the LTCH PPS standard Federal rate for 
the 2004 LTCH PPS rate year in this final rule, which will be effective 
for LTCHs paid under the LTCH PPS for discharges occurring on or after 
July 1, 2003, through June 30, 2004. In the final rule published on 
August 30, 2002 (67 FR 56029-56031), for cost reporting periods 
beginning on or after October 1, 2002 (FY 2003), we computed the LTCH 
PPS standard Federal payment rate by updating the best available (FY 
1998 or FY 1999) Medicare inpatient operating and capital costs per 
case data, using the excluded hospital market basket.
    Section 123(a)(1) of Public Law 106-113 requires that the PPS 
developed for LTCHs be budget neutral. Therefore, in calculating the 
standard Federal rate for FY 2003 under Sec.  412.523(d)(2), we set 
total estimated PPS payments equal to estimated payments that would 
have been made under the reasonable cost-based payment methodology had 
the PPS for LTCHs not been implemented. Section 307(a) of Public Law 
106-554 specified that the increases to the hospital-specific target 
amounts and cap on the target amounts for LTCHs for FY 2002 provided 
for by section 307(a)(1) of Public Law 106-554 shall not be taken into 
account in the development and implementation of the LTCH PPS. In 
addition, the statute as amended by section 122 of Public Law 106-113 
provides for enhanced bonus payments for LTCHs for two years, FY 2001 
and FY 2002. Furthermore, as specified at Sec.  412.523(d)(1), the 
standard Federal rate is reduced by an adjustment factor to account for 
the estimated proportion of outlier payments under the LTCH PPS to 
total LTCH PPS payments (8 percent). For further details on the 
development of the FY 2003 standard Federal rate, see the August 30, 
2002, final rule (67 FR 56027-56037). Under the existing regulations at 
Sec.  412.523(c)(3)(ii) for fiscal years after FY 2003, we update the 
standard Federal rate annually to adjust for the most recent estimate 
of the projected increases in prices for LTCH inpatient hospital 
services.

B. Update to the Standard Federal Rate for the 2004 LTCH PPS Rate Year

    In the August 30, 2002, final rule (67 FR 56033), we established a 
LTCH PPS standard Federal rate of $34,956.15 for FY 2003. As discussed 
in the March 7, 2003, proposed rule (68 FR 11248), based on the most 
recent estimate of the excluded hospital with capital market basket, 
adjusted to account for the change in the rate year update cycle for 
the LTCH PPS rates, we proposed that the LTCH PPS standard Federal 
rate, effective from July 1, 2003, through June 30, 2004, would be 
$35,726.64. Based on updated data, including the most recent estimate 
of the excluded hospital with capital market basket adjusted to account 
for the change in the rate year update cycle for the LTCH PPS rates, 
and the policies described in this final rule, the LTCH PPS standard 
Federal rate, effective from July 1, 2003, through June 30, 2004, is 
$35,726.18 (as discussed below).
    In the discussion that follows, we explain how we developed the 
update to the final standard Federal rate for the 2004 LTCH PPS rate 
year in this final rule. The final standard Federal rate for the 2004 
LTCH PPS rate year is calculated based on the final update factor of 
1.0220. Thus, we estimate that the final standard Federal rate for the 
2004 LTCH PPS rate year will increase 2.2 percent compared to the FY 
2003 standard Federal rate.
1. Standard Federal Rate Update
    In the August 30, 2002, final rule, we established at Sec.  412.523 
that, for years after FY 2003, the annual update to the LTCH PPS 
standard Federal rate will be equal to the percentage change in the 
excluded hospital with capital market basket (described in further 
detail below). As we discussed in the August 30, 2002, final rule (67 
FR 56087), in the future we may propose to develop a framework to 
update payments to LTCHs that would account for other appropriate 
factors that affect the efficient delivery of services and care 
provided to Medicare patients. As we stated in the March 7, 2003, 
proposed rule (68 FR 11244), because the LTCH PPS has only recently 
been implemented (for cost reporting periods beginning on or after 
October 1, 2002), we have not yet collected sufficient data to allow 
for the analysis and development of an update framework under the LTCH 
PPS. Therefore, in that same proposed rule, we did not propose an 
update framework for the 2004 LTCH PPS rate year. However, we noted 
that a conceptual basis for the proposal of developing an update 
framework in the future can be found in Appendix B of the August 30, 
2002, final rule (67 FR 56086-56090).
a. Description of the Market Basket for LTCHs for the 2004 LTCH PPS 
Rate Year
    A market basket has historically been used in the Medicare program 
to account for price increases of the services furnished by providers. 
The market basket used for the LTCH PPS includes both operating and 
capital-related costs of LTCHs because the LTCH PPS uses a single 
payment rate for both operating and capital-related costs. The 
development of the LTCH PPS standard Federal rate is discussed in 
further detail in the August 30, 2002 final rule (67 FR 56027-56037).
    Under the reasonable cost-based payment system, the excluded 
hospital market basket was used to update the hospital-specific limits 
on payment for operating costs of LTCHs. The excluded hospital market 
basket is based on operating costs from FY 1992 cost report data and 
includes data from Medicare-participating long-term care, 
rehabilitation, psychiatric, cancer, and children's hospitals. Since 
LTCHs' costs are included in the excluded hospital market basket, this 
market basket index, in part, also reflects the costs of LTCHs. 
However, in order to capture the total costs (operating and capital-
related) of LTCHs, we added a capital component to the excluded 
hospital market basket for use under the LTCH PPS. We refer to this 
index as the excluded hospital with capital market basket.
    As we discussed in both the August 30, 2002, final rule (67 FR 
56016 and 56086-56086) and the March 7, 2003, proposed rule (68 FR 
11245-11247), beginning with the implementation of the LTCH PPS in FY 
2003, the excluded hospital with capital market basket based on FY 1992 
Medicare cost report data has been used for updating payments to LTCHs. 
The FY 1992-based market basket reflected the distribution of costs in 
FY 1992 for Medicare-participating freestanding rehabilitation, long-
term care, psychiatric, cancer, and children's hospitals. This 
information was derived from the FY 1992 Medicare cost reports. A full 
discussion of the methodology and data sources used to construct the FY 
1992-based excluded hospital with capital market basket is included in 
Appendix A of the August 30, 2001, final rule (67 FR 56085-56086). In 
the March 7, 2003, proposed rule, we proposed to revise and rebase the 
excluded hospital with capital market basket, using more recent data, 
that is, using FY 1997 base year data beginning with the proposed 2004 
LTCH PPS rate year.
    As we stated in the March 7, 2003, proposed rule (68 FR 11245-
11247), we believe it was appropriate to propose to revise and rebase 
the LTCH PPS market basket based on the most recent complete data 
available (FY 1997) because these data would more accurately reflect 
LTCHs' current costs. Furthermore, we noted that this proposed revising 
and rebasing of the LTCH PPS market basket from an FY

[[Page 34135]]

1992 base year to a FY 1997 base year would be consistent with the 
rebasing of both the hospital inpatient market basket used under the 
IPPS and the excluded hospital market basket used to update the target 
amounts under the reasonable cost-based payment system for FY 2003, as 
discussed in the August 1, 2002, IPPS final rule (67 FR 50032-50047). 
We received no comments on the proposed revising and rebasing of the 
LTCH PPS market basket. Therefore, in this final rule, we are adopting 
the FY 1997-based excluded hospital with capital market basket as the 
LTCH PPS market basket beginning with the 2004 LTCH PPS rate year. 
Below we are providing a discussion of the development of the FY 1997-
based excluded hospital with capital market basket, as we presented in 
the March 7, 2003, proposed rule (68 FR 11245-11247).
    The operating portion of the FY 1997-based excluded hospital with 
capital market basket that we are using under the LTCH PPS beginning 
with the 2004 LTCH PPS rate year is derived from the FY 1997-based 
excluded hospital market basket used under the reasonable cost-based 
payment system. The methodology we used to develop the operating 
portion of the market basket under the LTCH PPS is the same methodology 
used to revise and rebase the excluded hospital market basket used 
under the reasonable cost-based payment system, which is described in 
greater detail in the August 1, 2002, IPPS final rule (67 FR 50042-
50044). In brief, the operating cost category weights in the FY 1997-
based excluded market basket add up to 100.0. These weights were 
determined based on FY 1997 Medicare cost report data, the 1997 
Business Expenditure Survey, and the 1997 Annual Input-Output data from 
the Bureau of the Census. In determining the FY 1997-based market 
basket, as we discussed in the March 7, 2003, proposed rule (68 FR 
11245-11247), we also revised the market basket by making the same two 
methodological revisions that we established when we revised and 
rebased the hospital inpatient market basket and the excluded hospital 
market basket in the August 1, 2002, IPPS final rule--(1) Changing the 
wage and benefit price proxies to use the Employment Cost Index (ECI) 
wage and benefit data for hospital workers; and (2) adding a cost 
category for blood and blood products.
    When we add the weight for capital costs to the excluded hospital 
market basket, the sum of the operating and capital weights must still 
equal 100.0. Based on data from FY 1997 Medicare cost reports for 
excluded hospitals, the capital cost weight is 8.968 percent. Because 
capital costs account for 8.968 percent of total costs for excluded 
hospitals in FY 1997, operating costs must, therefore, account for 
91.032 percent (100 percent minus 8.968 percent). Each operating cost 
category weight in the FY 1997-based excluded hospital market basket 
from the August 1, 2002, IPPS final rule (67 FR 50442-50444) was 
multiplied by 0.91032 to determine its weight in the FY 1997-based 
excluded hospital with capital market basket.
    As we discussed in the March 7, 2003, proposed rule (68 FR 11245-
11247), the aggregate capital component of the FY 1997-based excluded 
hospital market basket (8.968 percent) was determined from the same set 
of Medicare cost reports used to derive the operating component. The 
detailed capital cost categories of depreciation, interest, and other 
capital expenses were also determined using those Medicare cost 
reports. We needed to determine two sets of weights for the capital 
portion of the proposed revised and rebased market basket. The first 
set of weights identifies the proportion of capital expenditures 
attributable to each capital cost category; the second set represents 
relative vintage weights for depreciation and interest. The vintage 
weights identify the proportion of capital expenditures that is 
attributable to each year over the useful life of capital assets within 
a cost category (see 67 FR 50046-50047, August 1, 2002, for a 
discussion of how vintage weights are determined).
    The cost categories, price proxies, and base-year FY 1992 and FY 
1997 weights for the excluded hospital with capital market basket used 
under the LTCH PPS beginning with the 2004 LTCH PPS rate year are 
presented below in Table I. The vintage weights for the FY 1997-based 
excluded hospital with capital market basket are presented below in 
Table II.

\1\ The operating cost category weights in the excluded hospital market basket described in the August 1, 2002
  IPPS final rule (67 FR 50042-50044) add to 100.0. When we add an additional set of cost category weights
  (total capital weight = 8.968 percent) to this original group, the sum of the weights in the new index must
  still add to 100.0. Capital costs account for 8.968 percent of the market basket; operating costs account for
  91.032 percent. Each weight in the FY 1997-based excluded hospital market basket from the August 1, 2002 IPPS

    Table III. compares the FY 1992-based excluded hospital with 
capital market basket to the FY 1997-based excluded hospital with 
capital market basket. As shown in the table and as we discussed in the 
March 7, 2003, proposed rule (68 FR 11247), the revised and rebased 
market basket grows slightly faster over the FY 1999-2001 period than 
the FY 1992-based market basket. The major reason for this was the 
switching of the wage and benefit proxy to the ECI for hospital workers 
from the previous occupational blend. This revision had a similar 
impact on the IPPS and excluded market baskets, as described in the 
August 1, 2002, IPPS final rule (67 FR 50043-50047).

    In the August 30, 2002, LTCH PPS final rule (67 FR 56016 and 56085-
56086), we discussed why we believe the excluded hospital with capital 
market basket provides a reasonable measure of the price changes facing 
LTCHs. However, as we discussed in the March 7, 2003, proposed rule (68 
FR 11247), we have been researching the feasibility of developing a 
market basket specific to LTCH services. This research has included 
analyzing data sources for cost category weights, specifically the 
Medicare cost reports, and investigating other data sources on cost, 
expenditure, and price information specific to LTCHs. Based on this 
research, we did not propose to develop a market basket specific to 
LTCH services.
    As we stated in the March 7, 2003, proposed rule (68 FR 11247), our 
analysis of the Medicare cost reports indicates that the distribution 
of costs among major cost report categories (wages, pharmaceuticals, 
capital) for LTCHs is not substantially different from the 1997-based 
excluded hospital with capital market basket. Data on other major cost 
categories (benefits, blood, contract labor) that we would like to 
analyze were excluded by many LTCHs in their Medicare cost reports. An 
analysis based on only the data available to us for these cost 
categories presented a potential problem since no other major cost 
category weight would be based on LTCH data.
    Furthermore, as we discussed in the March 7, 2003, proposed rule 
(68 FR 11247), we conducted a sensitivity analysis of annual percent 
changes in the market basket when the weights for wages, 
pharmaceuticals, and capital in LTCHs were substituted into the 
excluded hospital with capital market basket. Other cost categories 
were recalibrated using ratios available from the IPPS market basket. 
On average between FY 1995 and FY 2002, the excluded hospital with 
capital market basket shows increases at nearly the same average annual 
rate (2.9 percent) as the market basket with LTCH weights for wages, 
pharmaceuticals, and capital (2.8 percent). This difference is less 
than the 0.25 percentage point criterion that determines whether a 
forecast error adjustment is warranted under the IPPS update framework.
    We believe that an excluded hospital with capital market basket 
adequately reflects the price changes facing LTCHs. In the March 7, 
2003, proposed rule, we stated that we would continue to solicit 
comments about issues particular to LTCHs that should be considered in 
relation to the FY 1997-based excluded hospital with capital market 
basket and to encourage suggestions for additional data sources that 
may be available.
    As we noted above, we received no comments on the proposed revising 
and rebasing of the LTCH PPS market basket. Accordingly, in this final 
rule, we are adopting the FY 1997-based excluded hospital with capital 
market basket as the LTCH PPS market basket for application beginning 
with the 2004 LTCH PPS rate year.
b. LTCH Market Basket Increase for the 2004 LTCH Rate Year
    As we discussed in the March 7, 2003, proposed rule (68 FR 11247), 
for LTCHs paid under the LTCH PPS, we proposed that the 2004 rate year 
update would apply to discharges occurring from July 1, 2003, through 
June 30, 2004. Because we are changing the timeframe of the LTCH PPS 
standard Federal rate annual update, as we discuss in section IV. of 
this preamble, we needed to calculate an update factor that will 
reflect this change in the update cycle. Presently, the current rate 
cycle is October 1, 2002, through September 30, 2003. This means that 
the FY 2003 standard Federal rate ($34,956.15; see the August 30, 2002, 
final rule (67 FR 56033)) was determined based on the market basket 
increase through September 30, 2003. As we explained in the March 7, 
2003, proposed rule (68 FR 11247), since we proposed to change the rate 
update cycle and, therefore, update the standard Federal rate 3 months 
early (that is, July 1, 2003, instead of October 1, 2003), we needed to 
propose an adjustment to the projected full (12-month) market basket 
increase to eliminate the projected increase for the 3-month 
overlapping period (July 1, 2003, through September 30, 2003).
    Thus, we need to account for the fact that the FY 2003 standard 
Federal rate of $34,956.15 already includes an update for the 3-month 
period from July 1, 2003, through September 30, 2003. In the absence of 
this proposed change, as we discussed in the March 7, 2003, proposed 
rule (68 FR 11247-11248), the update for FY 2004 would have been 
calculated using the estimated increase between FY 2003 and FY 2004. 
For the proposed update for the proposed 2004 LTCH PPS rate year, we 
calculated the estimated increase between FY 2003 and the proposed 2004 
LTCH PPS rate year. As we discussed in that same proposed rule, based 
on the fourth quarter 2002 forecast of the proposed revised and rebased 
FY 1997-based excluded hospital with capital market basket, we 
determined that the projected market basket increase for the 3-month 
period of July 1, 2003, through September 30, 2003, would be 0.8 
percentage points. The projected market basket increase for this 3-
month period (0.8 percent) was already included in the FY 2003 standard 
Federal rate and, therefore, needed to be deducted from the projected 
market basket increase for the 12-month period of July 1, 2003, through 
June 30, 2004 (3.3 percent), in order to account for the proposed 
change in the update cycle. Therefore,

[[Page 34138]]

in the March 7, 2003, proposed rule (68 FR 11248), based on Global 
Insights' (formerly DRI-WEFA) fourth quarter 2002 forecast of the 
proposed revised and rebased FY 1997-based excluded hospital with 
capital market basket we proposed an update of 2.5 percent for the 2004 
LTCH PPS rate year.
    We received no comments on our proposed methodology for calculating 
the market basket increase for the 2004 LTCH PPS rate year. Therefore, 
consistent with our historical practice of estimating market basket 
increases, based on Global Insights' (formerly DRI-WEFA) first quarter 
2003 forecast of the revised and rebased FY 1997-based excluded 
hospital with capital market basket, in this final rule using the 
methodology described above, we determined an update of 2.5 percent (as 
shown in Table IV. below) for the 2004 LTCH PPS rate year.

                                                                Percent

* Projected market basket increase for the 3-month period of July 1,
  2003, through September 30, 2003, already included in the FY 2003
  standard Federal rate.
** Projected market basket increase for the 12-month period of July 1,
  2003, through June 30, 2004, from FY 2003.

    In addition, as we discussed in the March 7, 2003, proposed rule 
(68 FR 11248), based on the best available data for 194 LTCHs, we 
estimated that LTCH prospective payment system payments would be 
approximately $1.960 billion for the proposed 2004 LTCH PPS rate year. 
Furthermore, as we discussed in the August 30, 2002, final rule (67 FR 
56027), we proposed that the proposed change to the annual update of 
the FY 2003 factors and rates from a rate year beginning October 1, 
2003, to a rate year beginning July 1, 2003, would maintain budget 
neutrality. In that same final rule, we explained that, as required by 
statute, total estimated LTCH PPS payments in FY 2003 will equal 
estimated payments that would have been made under the reasonable cost-
based principles if the LTCH PPS were not implemented. Therefore, in 
order to maintain budget neutrality for the proposed change in the rate 
update cycle, in the March 7, 2003, proposed rule (68 FR 11248), under 
proposed Sec.  412.523(c)(3)(ii), we proposed to adjust the standard 
Federal rate by a factor of 0.997 (($1.960 billion-$5.66 million)/
$1.960 billion) or -0.003 to account for the resulting additional cost 
of $5.66 million to the FY 2003 Federal budget that we estimated based 
on the most recent data for the 3-month period from July 1, 2003, 
through September 30, 2003. Also, in that same proposed rule, we 
proposed to revise this adjustment factor in this final rule based on 
the best available data.
    In this final rule, based on the best available data for 194 LTCHs, 
we estimated that LTCH prospective payment system payments would be 
approximately $1.960 billion for the 2004 LTCH PPS rate year. As we 
proposed in the March 7, 2003, proposed rule (68 FR 11248), the 
proposed change to the annual update of the FY 2003 factors and rates 
from a rate year beginning October 1, 2003, to a rate year beginning 
July 1, 2003, would be budget neutral because, as we noted above, total 
estimated LTCH PPS payments in FY 2003 must equal estimated payments 
that would have been made under the reasonable cost-based principles, 
if the LTCH PPS were not implemented. Therefore, in order to maintain 
budget neutrality for the change in the rate update cycle, in this 
final rule based on updated data and the final policies discussed in 
this final rule, under Sec.  412.523(c)(3)(ii), we have adjusted the 
2004 LTCH PPS rate year standard Federal rate by a factor of 0.997 
(($1.960 billion-$5.68 million)/$1.960 billion) or -0.003 to account 
for the resulting additional cost of $5.68 million to the FY 2003 
Federal budget that we estimated based on the most recent data for the 
3-month period from July 1, 2003, through September 30, 2003, for 194 
LTCHs.
    In the March 7, 2003, proposed rule (68 FR 11248), we proposed to 
update the current standard Federal rate ($34,956.15) established in 
the August 30, 2002, final rule (67 FR 56033) by 2.2 percent (2.5 
percent minus 0.3 percent) for discharges paid under the LTCH PPS that 
occur on or after July 1, 2003, through June 30, 2004. The proposed 
update represented the most recent estimate of the increase in the 
excluded hospital with capital market basket for the proposed 2004 LTCH 
PPS rate year, adjusted by the above described factor to transition to 
the proposed change in the rate update cycle to July 1, and is based on 
the best available data for 194 LTCHs.
    Comment: One commenter stated that the proposed 2.2 percent 
increase in the LTCH PPS standard Federal rate from $34.956.15 to 
$35,726.64 does not reflect the inflation of input hospital costs.
    Response: As noted above, the proposed update of 2.2 percent was 
based on the most recent estimate of the increase in the proposed 
excluded hospital with capital market basket for the proposed 2004 LTCH 
PPS rate year, adjusted as explained above to transition to the 
proposed change in the rate update cycle to July 1. The proposed update 
and adjustment were based on the best available data for 194 LTCHs 
contained in our database. The most recent estimate of the increase in 
the excluded hospital with capital market basket for the 2004 LTCH PPS 
rate year was determined in a manner that is consistent with our 
historical pra
