SUPPLEMENTARY INFORMATION:

I. Executive Summary

A. Purpose

    This final rule updates the prospective payment rates for inpatient 
rehabilitation facilities (IRFs) for Fiscal Year (FY) 2026 (that is, 
for discharges occurring on or after October 1, 2025, and on or before 
September 30, 2026) under section 1886(j)(3)(C) of the Social Security 
Act (the Act). As required by section 1886(j)(5) of the Act, this final 
rule includes the classification and weighting factors for the IRF 
prospective payment system (PPS) case-mix groups (CMGs), and a 
description of the methodologies and data used in computing the 
prospective payment rates for FY 2026.
    For the IRF Quality Reporting Program (QRP), this rule finalizes 
our proposals to remove two quality measures: (1) the COVID-19 
Vaccination Coverage among Healthcare Personnel (HCP) measure, 
beginning with the FY 2026 IRF QRP, and (2) the COVID-19 Vaccine: 
Percent of Patients/Residents Who Are Up to Date measure, beginning 
with the FY 2028 IRF QRP. Next, we are finalizing proposals to remove 
four Standardized Patient Assessment Data Elements under the Social 
Determinant of Health (SDOH) category from the IRF Patient Assessment 
Instrument (IRF-PAI) beginning with the FY 2028 IRF QRP. We are also 
finalizing proposals amending our reconsideration policy. Finally, we 
provide summaries of the comments received in response to a Request for 
Information (RFI) on four separate considerations: (1) future measure 
concepts for the IRF QRP; (2) potential revisions to the IRF-Patient 
Assessment Instrument (PAI); (3) potential revisions to the data 
submission deadlines for assessment data collected for the IRF QRP; and 
(4) advancing digital quality measurement in IRFs.

B. Summary of Major Provisions

    In this final rule, we use the methods described in the FY 2025 IRF 
PPS final rule (89 FR 64276) to update the prospective payment rates 
for FY 2026 using the most current and complete data available at this 
time, which is FY 2024 IRF claims and FY 2023 IRF cost report data, as 
discussed in section VI, of this final rule.
    For the IRF QRP, this rule will remove two quality measures, remove 
four SDOH standardized patient assessment data elements, and amend our 
reconsideration policy. We also include summaries of comments received 
in response to Requests for Information (RFIs) on four separate 
considerations.

II. Background

A. Statutory Basis and Scope for IRF PPS Provisions

    Section 1886(j) of the Act provides for the implementation of a 
per-discharge PPS for inpatient rehabilitation hospitals and inpatient 
rehabilitation units of a hospital (collectively, hereinafter referred 
to as IRFs). Payments under the IRF PPS encompass inpatient operating 
and capital costs of furnishing covered rehabilitation services (that 
is, routine, ancillary, and capital costs), but not direct graduate 
medical education costs, costs of approved nursing and allied health 
education activities, bad debts, and other services or items outside 
the scope of the IRF PPS. A complete discussion of the IRF PPS 
provisions appears in the original FY 2002 IRF PPS final rule (66 FR 
41316) and the FY 2006 IRF PPS final rule (70 FR 47880) and we provided 
a general description of the IRF PPS for FYs 2007 through 2019 in the 
FY 2020 IRF PPS final rule (84 FR 39055 through 39057). A general 
description of the IRF PPS for FYs 2020 through 2025, along with 
detailed background information for various other aspects of the IRF 
PPS, is now available on the CMS website at <a href="https://www.cms.gov/files/document/irf-regulatory-and-legislative-history.pdf">https://www.cms.gov/files/document/irf-regulatory-and-legislative-history.pdf</a>.
    Under the IRF PPS from FYs 2002 through 2005, the prospective 
payment rates were computed across 100 distinct CMGs, as described in 
the FY 2002 IRF PPS final rule (66 FR 41316). We constructed 95 CMGs 
using rehabilitation impairment categories (RICs), functional status 
(both motor and cognitive), and age (in some cases, cognitive status 
and age may not be a factor in defining a CMG). In addition, we 
constructed five special CMGs to account for very short stays and for 
patients who expire in the IRF.
    For each of the CMGs, we developed relative weighting factors to 
account for a patient's clinical characteristics and expected resource 
needs. Thus, the weighting factors accounted for the relative 
difference in resource use across all CMGs. Within each CMG, we created 
tiers based on the estimated effects that certain comorbidities would 
have on resource use.
    We established the Federal PPS rates using a standardized payment 
conversion factor (formerly referred to as the budget-neutral 
conversion factor). For a detailed discussion of the budget-neutral 
conversion factor, please refer to our FY 2004 IRF PPS final rule (68 
FR 45684 through 45685). In the FY 2006 IRF PPS final rule (70 FR 
47880), we discussed in detail the methodology for determining the 
standard payment conversion factor.
    We applied the relative weighting factors to the standard payment 
conversion factor to compute the unadjusted prospective payment rates 
under the IRF PPS from FYs 2002 through 2005. Within the structure of 
the payment system, we then made adjustments to account for interrupted 
stays, transfers, short stays, and deaths. Finally, we applied the 
applicable adjustments to account for geographic variations in wages 
(wage index), the percentage of low-income patients, location in a 
rural area (if applicable), and outlier payments (if applicable) to the 
IRFs' unadjusted prospective payment rates.
    For cost reporting periods that began on or after January 1, 2002, 
and before October 1, 2002, we determined the final prospective payment 
amounts using the transition methodology prescribed in section 
1886(j)(1) of the Act. Under this provision, IRFs transitioning into 
the PPS were paid a blend of the Federal IRF PPS rate and the payment 
that the IRFs would have received had the IRF PPS not been implemented. 
This provision also allowed IRFs to elect to bypass this blended 
payment and immediately be paid 100 percent of the Federal IRF PPS 
rate. The transition methodology expired as of cost reporting periods 
beginning on or after October 1, 2002 (FY 2003), and payments for all 
IRFs now consist of 100 percent of the Federal IRF PPS rate.
    Section 1886(j) of the Act confers broad statutory authority upon 
the Secretary to propose refinements to the IRF PPS. In the FY 2006 IRF 
PPS final rule (70 FR 47880) and in correcting amendments to the FY 
2006 IRF PPS final rule (70 FR 57166), we finalized a number of 
refinements to the IRF PPS case-mix classification system (the CMGs and 
the corresponding relative weights) and the case-level and facility-
level adjustments. These refinements included the adoption of the 
Office of Management and Budget's (OMB's) Core-Based Statistical Area 
market definitions; modifications to the CMGs, tier comorbidities; and 
CMG relative weights, implementation of a new teaching status 
adjustment for IRFs; rebasing and revising the market basket used to 
update IRF payments, and updates to the rural, low-income percentage 
(LIP), and high-cost outlier adjustments. Beginning with the FY 2006 
IRF PPS final rule (70 FR 47908 through 47917), the market basket used 
to update IRF payments was a market basket reflecting the operating and 
capital cost structures for freestanding IRFs, freestanding inpatient 
psychiatric facilities (IPFs), and long-term care hospitals (LTCHs). 
Any reference to the FY 2006 IRF PPS final rule in this proposed rule 
also includes the provisions effective in the correcting amendments. 
For a detailed discussion of the final key policy changes for FY 2006, 
please refer to the FY 2006 IRF PPS final rule.
    In response to COVID-19 Public Health Emergency (PHE), we published 
two interim final rules with comment period affecting IRF payment and 
conditions for participation. The interim final rule with comment 
period (IFC) entitled ``Medicare and Medicaid Programs; Policy and 
Regulatory Revisions in Response to the COVID-19 Public Health 
Emergency,'' published on April 6, 2020 (85 FR 19230) (hereinafter 
referred to as the April 6, 2020 IFC), included certain changes to the 
IRF PPS medical supervision requirements at 42 CFR 412.622(a)(3)(iv) 
and 412.29(e) during the PHE for COVID-19. In addition, in the April 6, 
2020 IFC, we removed the post-admission physician evaluation 
requirement at Sec.  412.622(a)(4)(ii) for all IRFs during the PHE for 
COVID-19. In the FY 2021 IRF PPS final rule, to ease documentation and 
administrative burden, we permanently removed the post-admission 
physician evaluation documentation requirement at Sec.  
412.622(a)(4)(ii) beginning in FY 2021.
    A second IFC, entitled ``Medicare and Medicaid Programs, Basic 
Health Program, and Exchanges; Additional Policy and Regulatory 
Revisions in Response to the COVID-19 Public Health Emergency and Delay 
of Certain Reporting Requirements for the Skilled Nursing Facility 
Quality Reporting Program,'' was published on May 8, 2020 (85 FR 27550) 
(hereinafter referred to as the May 8, 2020 IFC). Among other changes, 
the May 8, 2020 IFC included a waiver of the ``3-hour rule'' at Sec.  
412.622(a)(3)(ii) to reflect the waiver required by section 3711(a) of 
the Coronavirus Aid, Relief, and Economic Security Act (CARES Act) 
(Pub. L. 116-136, enacted on March 27, 2020). In the May 8, 2020 IFC, 
we also modified certain IRF coverage and classification requirements 
for freestanding IRF hospitals to relieve acute care hospital capacity 
concerns in States (or regions, as applicable) experiencing a surge 
during the PHE for COVID-19. In addition to the policies adopted in our 
IFCs, we responded to the PHE with numerous blanket waivers \1\ and 
other

[[Page 37680]]

flexibilities,\2\ some of which are applicable to the IRF PPS. CMS 
finalized these policies in the Calendar Year 2023 Hospital Outpatient 
Prospective Payment and Ambulatory Surgical Center Payment Systems 
final rule with comment period (87 FR 71748). Subsequently, on May 11, 
2023, the U.S. Department of Health and Human Services (``HHS'') 
declared the expiration of the COVID-19 PHE. (See <a href="https://www.hhs.gov/about/news/2023/02/09/fact-sheet-covid-19-public-health-emergency-transition-roadmap.html">https://www.hhs.gov/about/news/2023/02/09/fact-sheet-covid-19-public-health-emergency-transition-roadmap.html</a>.) As a result, the ``3-hour rule'' waiver at 
Sec.  412.622(a)(3)(ii) and other IRF flexibilities were terminated.

B. Provisions of the Affordable Care Act and the Medicare Access and 
CHIP Reauthorization Act of 2015 (MACRA) Affecting the IRF PPS in FY 
2012 and Beyond

    The Patient Protection and Affordable Care Act (Pub. L. 111-148) 
was enacted on March 23, 2010. The Health Care and Education 
Reconciliation Act of 2010 (Pub. L. 111-152), which amended and revised 
several provisions of the Patient Protection and Affordable Care Act, 
was enacted on March 30, 2010. In this final rule, we refer to the two 
statutes collectively as the ``Affordable Care Act'' or ``ACA''.
    The ACA included several provisions that affect the IRF PPS in FYs 
2012 and beyond. In addition to what was previously discussed, section 
3401(d) of the ACA also added section 1886(j)(3)(C)(ii)(I) of the Act 
(providing for a ``productivity adjustment'' for FY 2012 and each 
subsequent FY). The productivity adjustment for FY 2026 is discussed in 
section VI. of this final rule. Section 1886(j)(3)(C)(ii)(II) of the 
Act provides that the application of the productivity adjustment to the 
market basket percentage increase may result in an update that is less 
than 0.0 for a FY and in payment rates for a FY being less than such 
payment rates for the preceding FY.
    Section 3004(b) of the ACA and section 411(b) of the MACRA (Pub. L. 
114-10, enacted on April 16, 2015) also addressed the IRF PPS. Section 
3004(b) of ACA reassigned the previously designated section 1886(j)(7) 
of the Act to section 1886(j)(8) of the Act and inserted a new section 
1886(j)(7) of the Act, which contains requirements for the Secretary to 
establish a QRP for IRFs. Under that program, data must be submitted in 
a form and manner and at a time specified by the Secretary. Beginning 
in FY 2014, section 1886(j)(7)(A)(i) of the Act requires the 
application of a 2-percentage point reduction to the IRF market basket 
percentage increase otherwise applicable to an IRF (after application 
of paragraphs (C)(iii) and (D) of section 1886(j)(3) of the Act) for a 
FY if the IRF does not comply with the requirements of the IRF QRP for 
that FY. Application of the 2-percentage point reduction may result in 
an update that is less than 0.0 for a FY and in payment rates for a FY 
being lower than payment rates for the preceding FY. Reporting-based 
reductions to the IRF market basket percentage increase are not 
cumulative; they only apply for the FY involved. Section 411(b) of the 
MACRA amended section 1886(j)(3)(C) of the Act by adding paragraph 
(iii), which required us to apply for FY 2018, after the application of 
section 1886(j)(3)(C)(ii) of the Act, an increase factor of 1.0 percent 
to update the IRF prospective payment rates.

C. Operational Overview of the Current IRF PPS

    As described in the FY 2002 IRF PPS final rule (66 FR 41316), upon 
the admission and discharge of a Medicare Part A fee-for-service (FFS) 
patient, the IRF is required to complete the appropriate sections of a 
Patient Assessment Instrument (PAI), designated as the IRF-PAI. In 
addition, beginning with IRF discharges occurring on or after October 
1, 2009, the IRF is also required to complete the appropriate sections 
of the IRF-PAI upon the admission and discharge of each MA patient, as 
described in the FY 2010 IRF PPS final rule (74 FR 39762) and the FY 
2010 IRF PPS correction notice (74 FR 50712). All required data must be 
electronically encoded into the IRF-PAI software product. Generally, 
the software product includes patient classification programming called 
the Grouper software. The Grouper software uses specific IRF-PAI data 
elements to classify (or group) patients into distinct CMGs and account 
for the existence of any relevant comorbidities.
    The Grouper software produces a five-character CMG number. The 
first character is an alphabetic character that indicates the 
comorbidity tier. The last four characters are numeric characters that 
represent the distinct CMG number. A free download of the Grouper 
software is available on the CMS website at <a href="https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/InpatientRehabFacPPS/Software.html">https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/InpatientRehabFacPPS/Software.html</a>. The Grouper software is also embedded in the internet 
Quality Improvement and Evaluation System (iQIES) User tool available 
in iQIES at <a href="https://www.cms.gov/medicare/quality-safety-oversight-general-information/iqies">https://www.cms.gov/medicare/quality-safety-oversight-general-information/iqies</a>.
    Once a Medicare Part A FFS patient is discharged, the IRF submits a 
Medicare claim as a Health Insurance Portability and Accountability Act 
of 1996 (HIPAA) (Pub. L. 104-191, 110 Stat. 1936 August 21, 1996) 
compliant electronic claim or, if the Administrative Simplification 
Compliance Act of 2002 (ASCA) (Pub. L. 107-105, enacted on December 27, 
2002) permits, a paper claim (a UB-04 or a CMS-1450 as appropriate) 
using the five-character CMG number and sends it to the appropriate 
Medicare Administrative Contractor (MAC). In addition, once a MA 
patient is discharged, in accordance with the Medicare Claims 
Processing Manual, chapter 3, section 20.3 (Pub. 100-04), hospitals 
(including IRFs) must submit to their MAC an informational-only bill 
(type of bill (TOB) 111) that includes Condition Code 04. This will 
ensure that the MA days are included in the hospital's Supplemental 
Security Income (SSI) ratio (used in calculating the IRF LIP 
adjustment) for FY 2007 and beyond. Claims submitted to Medicare must 
comply with- both ASCA and HIPAA.
    Section 3 of the ASCA amended section 1862(a) of the Act by adding 
paragraph (22), which requires the Medicare program, subject to section 
1862(h) of the Act, to deny payment under Part A or Part B for any 
expenses for items or services for which a claim is submitted other 
than in an electronic form specified by the Secretary. Section 1862(h) 
of the Act, in turn, provides that the Secretary shall waive such 
denial in situations in which there is no method available for the 
submission of claims in an electronic form or the entity submitting the 
claim is a small provider. In addition, the Secretary also has the 
authority to waive such denial in such unusual cases as the Secretary 
finds appropriate. For more information, see the ``Medicare Program; 
Electronic Submission of Medicare Claims'' final

[[Page 37681]]

rule (70 FR 71008). Our instructions for the limited number of Medicare 
claims submitted on paper are available at <a href="https://www.cms.gov/manuals/downloads/clm104c25.pdf">https://www.cms.gov/manuals/downloads/clm104c25.pdf</a>.
    Section 3 of the ASCA operates in the context of the administrative 
simplification provisions of HIPAA, which include, among others, the 
requirements for transaction standards and code sets codified in 45 CFR 
part 160 and part 162, subparts A and I through R (generally known as 
the Transactions Rule). The Transactions Rule requires covered 
entities, including covered healthcare providers, to conduct covered 
electronic transactions according to the applicable transaction 
standards. (See the CMS program claim memoranda at <a href="https://www.cms.gov/ElectronicBillingEDITrans/">https://www.cms.gov/ElectronicBillingEDITrans/</a> and listed in the addenda to the Medicare 
Intermediary Manual, Part 3, section 3600.)
    The MAC processes the claim through its software system. This 
software system includes pricing programming called the ``Pricer'' 
software. The Pricer software uses the CMG number, along with other 
specific claim data elements and provider-specific data, to adjust the 
IRF's prospective payment for interrupted stays, transfers, short 
stays, and deaths, and then applies the applicable adjustments to 
account for the IRF's wage index, percentage of low-income patients, 
rural location, and outlier payments. For discharges occurring on or 
after October 1, 2005, the IRF PPS payment also reflects the teaching 
status adjustment that became effective as of FY 2006, as discussed in 
the FY 2006 IRF PPS final rule (70 FR 47880).

III. Summary of Provisions of the Final Rule

    In this FY 2026 IRF PPS final rule, we are finalizing our proposal 
to update the IRF PPS for FY 2026 and the IRF QRP for FY 2026 and FY 
2028.
    The finalized policy changes and updates to the IRF prospective 
payment rates for FY 2026 will be as follows:
    <bullet> Update the CMG relative weights and average length of stay 
values for FY 2026 in a budget neutral manner, as discussed in section 
V of this final rule.
    <bullet> Update the IRF PPS payment rates for FY 2026 by the IRF 
market basket percentage increase, based upon the most current data 
available, with a productivity adjustment required by section 
1886(j)(3)(C)(ii)(I) of the Act, as described in section VI.
    <bullet> Update the FY 2026 IRF PPS payment rates by the FY 2026 
wage index, applying the second year of the phase-out of the rural 
adjustment for IRFs transitioning from rural to urban, and the labor-
related share in a budget-neutral manner, as discussed in section VI.
    <bullet> Describe the calculation of the IRF standard payment 
conversion factor for FY 2026, as discussed in section VI.
    <bullet> Update the outlier threshold amount for FY 2026, as 
discussed in section VI.
    <bullet> Update the cost-to-charge ratio (CCR) ceiling and urban/
rural average CCRs for FY 2026, as discussed in section VI.
    The policy changes and updates to the IRF QRP for FY 2026 will be 
as follows:
    <bullet> Remove the COVID-19 Vaccination Coverage among Healthcare 
Personnel (HCP) measure.
    <bullet> Amend the Reconsideration Policy.
    The proposed policy changes and updates to the IRF QRP for FY 2028 
will be as follows:
    <bullet> Remove the COVID-19 Vaccine: Percent of Patients/Residents 
Who Are Up to Date measure.
    <bullet> Remove four SDOH standardized patient assessment data 
elements items from the IRF-PAI.
    We summarize the comments we received on the following four RFIs:
    <bullet> Request for information on future measure concepts for the 
IRF QRP.
    <bullet> Request for information on potential revisions to the IRF-
PAI.
    <bullet> Request for information on potential revisions to the data 
submission deadlines for assessment data collected for the IRF QRP.
    <bullet> Request for information on advancing digital quality 
measurement in IRFs.

IV. Public Comments

A. Analysis of and Responses to Public Comments

    We received 69 timely responses from the public, many of which 
contained multiple comments on the FY 2026 IRF PPS proposed rule (90 FR 
18534). We received comments from various trade associations, inpatient 
rehabilitation facilities, individual physicians, therapists, 
clinicians, healthcare industry organizations, healthcare consulting 
firms, technology vendors, academic institutions, and anonymous 
persons. The following sections, arranged by subject area, include a 
summary of the public comments that we received, and our responses.

B. General Comments on the FY 20206 IRF PPS Proposed Rule

    In addition to the comments we received on specific proposals 
contained within the proposed rule (which we address later in this 
final rule), commenters also submitted more general observations on the 
IRF PPS and IRF care generally.
    Comment: We received comments that were outside the scope of the FY 
2026 IRF PPS proposed rule. These comments related to adopting a 
national healthcare system, updating the facility level adjustments 
based on a 3-year average that is capped for the teaching coefficient, 
and considering a future proposal to expand the role of PAs in IRFs and 
modify paragraphs (a)(3)(iv) and (a)(4)(ii) of Sec.  412.622. Although 
comments also raised concerns regarding several issues related to MA 
plans, we did not propose changes to MA and Medicaid managed care plan 
regulations in this rule. One commenter urged CMS to allow the 
rehabilitation physician the opportunity to determine which disciplines 
should provide care within the 3-hour or level of intensity of services 
rule and recommended recreational therapy interventions (when 
applicable) to be counted towards the level of intensity rule.
    Response: We thank the commenters for bringing these issues to our 
attention, and we will take these comments into consideration for 
potential policy refinements or direct the comments to the appropriate 
subject matter experts.

V. Updates to the Case-Mix Group (CMG) Relative Weights and Average 
Length of Stay (ALOS) Values for FY 2026

    As specified in Sec.  412.620(b)(1), we calculate a relative weight 
for each CMG that is proportional to the resources needed for an 
average inpatient rehabilitation case in that CMG. For example, cases 
in a CMG with a relative weight of 2, on average, will cost twice as 
much as cases in a CMG with a relative weight of 1. Relative weights 
account for the variance in cost per discharge due to the variance in 
resource utilization among the payment groups, and their use helps to 
ensure that IRF PPS payments support beneficiary access to care, as 
well as provider efficiency.
    In this final rule, we update the CMG relative weights and ALOS 
values for FY 2026. Typically, we use the most recent available data to 
update the CMG relative weights and ALOS values. For FY 2026, we are 
using the FY 2024 IRF claims and FY 2023 IRF cost report data (CMS Form 
2552-10, OMB No 0938-0050). These data are the most current and 
complete data available at the time of this final rule. Currently, only 
a small portion of the FY 2024 IRF cost report data is available for 
analysis, but the

[[Page 37682]]

majority of the FY 2024 IRF claims data are available for analysis.
    In the FY 2026 IRF PPS proposed rule, we proposed that if more 
recent data became available after the publication of the proposed rule 
and before the publication of this final rule, we would use such data 
to determine the FY 2026 CMG relative weights and ALOS values in this 
final rule.
    We proposed to apply these data using the same methodologies that 
we have used to update the CMG relative weights and ALOS values each FY 
since we implemented an update to the methodology. The detailed cost-
to-charge ratio (CCR) data from the cost reports of IRF provider units 
of primary acute care hospitals is used for this methodology, instead 
of CCR data from the associated primary care hospitals, to calculate 
IRFs' average costs per case, as discussed in the FY 2009 IRF PPS final 
rule (73 FR 46372). In calculating the CMG relative weights, we use a 
hospital-specific relative value method to estimate the operating 
(routine and ancillary services) and capital costs of IRFs. The process 
to calculate the CMG relative weights for this final rule is as 
follows:
    Step 1. We estimate the effects that comorbidities have on costs.
    Step 2. We adjust the cost of each Medicare discharge (case) to 
reflect the effects found in Step 1.
    Step 3. We use the adjusted costs from Step 2 to calculate CMG 
relative weights, using the hospital-specific relative value method.
    Step 4. We normalize the FY 2026 CMG relative weights using a 
normalization factor that results in the average CMG relative weights 
in FY 2026 being the same as the average CMG relative weights in the FY 
2025 IRF PPS final rule (89 FR 64276).
    Consistent with the methodology that we have used to update the IRF 
classification system in each instance in the past, we are updating the 
CMG relative weights for FY 2026 in such a way that total estimated 
aggregate payments to IRFs for FY 2026 are the same with or without the 
changes (that is, in a budget-neutral manner) by applying a budget 
neutrality factor to the standard payment amount. To calculate the 
appropriate budget neutrality factor for use in updating the FY 2026 
CMG relative weights, we use the following steps:
    Step 1. Calculate the estimated total amount of IRF PPS payments 
for FY 2026 (with no changes to the CMG relative weights).
    Step 2. Calculate the estimated total amount of IRF PPS payments 
for FY 2026 by applying the proposed changes to the CMG relative 
weights (as discussed in this proposed rule).
    Step 3. Divide the amount calculated in Step 1 by the amount 
calculated in Step 2 to determine the budget neutrality factor of 
0.9985 that would maintain the same total estimated aggregate payments 
in FY 2026 with and without the proposed changes to the final CMG 
relative weights.
    Step 4. Apply the budget neutrality factor from Step 3 to the FY 
2026 IRF PPS standard payment amount after the application of the 
budget-neutral wage adjustment factor.
    In section V of this final rule, we discuss the proposed use of the 
existing methodology to calculate the proposed standard payment 
conversion factor for FY 2026.
    In Table 2, ``Relative Weights and Average Length of Stay Values 
for Case -Mix Groups,'' we present the CMGs, the comorbidity tiers, the 
corresponding relative weights, and the ALOS values for each CMG and 
tier for FY 2026. The ALOS for each CMG is used to determine when an 
IRF discharge meets the definition of a short stay transfer, which 
results in a per diem case level adjustment.

    Generally, updates to the CMG relative weights result in some 
increases and some decreases to the CMG relative weight values. Table 3 
shows how we estimate that the application of the revisions for FY 2026 
would affect particular CMG relative weight values, which would affect 
the overall distribution of payments within CMGs and tiers. We note 
that, because we implement the CMG relative weight revisions in a 
budget-neutral manner (as previously described), total estimated 
aggregate payments to IRFs for FY 2026 would not be affected as a 
result of the CMG relative weight revisions. However, the revisions 
would affect the distribution of payments within CMGs and tiers.

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

    As shown in Table 3, 99.2 percent of all IRF cases are in CMGs and 
tiers that would experience less than a 5 percent change (either 
increase or decrease) in the CMG relative weight value as a result of 
the revisions for FY 2026. The changes in the ALOS values for FY 2026, 
compared with the FY 2025 ALOS values, are small and do not show any 
particular trends in IRF length of stay patterns.
    We invited public comment on our proposed updates to the CMG 
relative weights and ALOS values for FY 2026.
    The following is a summary of the public comments received on the 
proposed updates to the CMG relative weights and ALOS and our 
responses:
    Comment: Public comments generally supported CMS' update to the CMG 
relative weights and average length of stay values and encouraged CMS 
to use the latest available data to update these values in the final 
rule. A few commenters recommend future refinements to computing the 
CMGs and use of the ALOS.
    Response: We appreciate these commenters' support for updating the 
relative weights and ALOS values for FY 2026. We have updated our data 
between the FY 2026 IRF PPS proposed and this final rule to ensure that 
we use the most recent available data in calculating IRF PPS payments.
    The methodology that we use to update the CMG relative weights uses 
the most recent cost data reported by IRFs to compute relative weights 
that reflect the relative costliness of different IRF cases in a budget 
neutral manner. We increase or decrease relative weights of the CMGs 
annually, including for those CMGs associated with the 13 conditions 
that qualify for the 60 percent rule, under 42 CFR 412.29(b)(2), based 
only on the cost data reported to us by IRFs each year.
    We believe that these data accurately reflect the severity of the 
IRF patient population and the associated costs of caring for these 
patients in the IRF setting. The CMG relative weights are updated each 
year based on the most recent available data for the full population of 
IRF Medicare fee-for-service beneficiaries. This ensures that the IRF 
case -mix system is as reflective as possible of changes in the IRF 
patient populations and the associated coding practices and ensures 
that IRF payments appropriately reflect the relative costs of caring 
for all types of IRF patients.
    Comment: The Medicare Payment Advisory Commission (MedPAC) 
submitted a comment recommending that CMS consider using an average-
cost weighting method, rather than the current hospital-specific 
relative value method (HSRV), for calculating the CMG relative weights, 
to improve the relationship between costs and payments and increase the 
uniformity of profitability across IRF cases.
    Response: We did not propose any changes to the current HSRV method 
used to assign payment weights for FY 2025 and believe that a careful 
evaluation of the advantages and disadvantages of moving to an average-
cost weighting method is essential, given the major distributional 
shifts that would be associated with such a change. The purpose of the 
HSRV method is, in part, to place a greater emphasis on more efficient 
IRF providers (that is, those that treat complex IRF patients at lower 
costs). CMS believes moving to an average-cost weighting method places 
more emphasis on high cost IRF providers, which could have higher costs 
because they are operating less efficiently. We will continue 
evaluating the effects of changing from HSRV weighting to average-cost 
weighting. The results of this analysis will inform future rulemaking.
    After consideration of the comments we received, we are finalizing 
our proposal to update the CMG relative weights and ALOS values for FY 
2026 using the same methodologies that we have used to update the CMG 
relative weights and ALOS values for each FY since we implemented an 
update to the methodology in FY 2009, as shown in Table 2 of this final 
rule. These updates are effective for FY 2026, that is, for discharges 
occurring on or after October 1, 2025, and on or before September 30, 
2026.

VI. FY 2026 IRF PPS Payment Update

A. Background

    Section 1886(j)(3)(C) of the Act requires the Secretary to 
establish an increase factor that reflects changes over time in the 
prices of an appropriate mix of goods and services for which payment is 
made under the IRF PPS. According to section 1886(j)(3)(A)(i) of the 
Act, the increase factor shall be used to update the IRF prospective 
payment rates for each FY. Section 1886(j)(3)(C)(ii)(I) of the Act 
requires the application of the productivity adjustment described in 
section 1886(b)(3)(B)(xi)(II) of the Act. Thus, we proposed to update 
the IRF PPS payments for FY 2026 by a market basket percentage increase 
as required by section 1886(j)(3)(C) of the Act based upon the most 
current data available, with a productivity adjustment as required by 
section 1886(j)(3)(C)(ii)(I) of the Act.
    We have utilized various market baskets through the years in the 
IRF PPS. For a discussion of these market baskets, we refer readers to 
the FY 2016 IRF PPS final rule (80 FR 47046).
    Beginning with FY 2024, we finalized a rebased and revised IRF 
market basket

[[Page 37688]]

to reflect a 2021 base year. The FY 2024 IRF PPS final rule (88 FR 
50966 through 50988) contains a complete discussion of the development 
of the 2021-based IRF market basket.

B. FY 2026 Market Basket Update and Productivity Adjustment

1. FY 2026 Market Basket Update
    For FY 2026 (that is, beginning October 1, 2025, and ending 
September 30, 2026), we proposed to update the IRF PPS payments by a 
market basket percentage increase as required by section 1886(j)(3)(C) 
of the Act, with a productivity adjustment as required by section 
1886(j)(3)(C)(ii)(I) of the Act. For FY 2026, we proposed to use the 
same methodology described in the FY 2025 IRF PPS final rule (89 FR 
64285 through 64286).
    Consistent with historical practice, we proposed to estimate the 
market basket update for the IRF PPS for FY 2026 based on IHS Global 
Inc.'s (IGI's) \3\ forecast using the most recent available data at the 
time of rulemaking. IGI is a nationally recognized economic and 
financial forecasting firm with which CMS contracts to forecast the 
components of the market baskets. Based on IGI's fourth quarter 2024 
forecast with historical data through the third quarter of 2024, the 
proposed 2021-based IRF market basket percentage increase for FY 2026 
was projected to be 3.4 percent. We also proposed that if more recent 
data became available after the publication of the proposed rule and 
before the publication of this final rule (for example, a more recent 
estimate of the market basket percentage increase or productivity 
adjustment), we would use such data, if appropriate, to determine the 
FY 2026 IRF market basket update in this final rule. Based on IGI's 
second quarter 2025 forecast with historical data through the first 
quarter of 2025, the 2021-based IRF market basket percentage increase 
for FY 2026 is 3.3 percent.

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

2. FY 2026 Productivity Adjustment
    According to section 1886(j)(3)(C)(i) of the Act, the Secretary 
shall establish an increase factor based on an appropriate percentage 
increase in a market basket of goods and services. Section 
1886(j)(3)(C)(ii) of the Act requires that, after establishing the 
increase factor for a FY, the Secretary shall reduce such increase 
factor for FY 2012 and each subsequent FY, by the productivity 
adjustment described in section 1886(b)(3)(B)(xi)(II) of the Act. 
Section 1886(b)(3)(B)(xi)(II) of the Act sets forth the definition of 
this productivity adjustment. The statute defines the productivity 
adjustment to be equal to the 10-year moving average of changes in 
annual economy-wide, private nonfarm business multifactor productivity 
(as projected by the Secretary for the 10-year period ending with the 
applicable FY, year, cost reporting period, or other annual period) 
(the ``productivity adjustment''). The U.S. Department of Labor's 
Bureau of Labor Statistics (BLS) publishes the official measures of 
productivity for the U.S. economy. We note that previously the 
productivity measure referenced in section 1886(b)(3)(B)(xi)(II) of the 
Act, was referred to by BLS as private nonfarm business multifactor 
productivity. Beginning with the November 18, 2021, release of 
productivity data, BLS replaced the term multifactor productivity (MFP) 
with total factor productivity (TFP). BLS noted that this is a change 
in terminology only and will not affect the data or methodology. As a 
result of this change, the productivity measure referenced in section 
1886(b)(3)(B)(xi)(II) of the Act is now published by BLS as private 
nonfarm business total factor productivity. However, as mentioned 
above, the data and methods are unchanged. Please see <a href="http://www.bls.gov">www.bls.gov</a> for 
the BLS historical published TFP data. A complete description of IGI's 
TFP projection methodology is available on the CMS website at <a href="https://www.cms.gov/data-research/statistics-trends-and-reports/medicare-program-rates-statistics/market-basket-research-and-information">https://www.cms.gov/data-research/statistics-trends-and-reports/medicare-program-rates-statistics/market-basket-research-and-information</a>. In 
addition, in the FY 2022 IRF final rule (86 FR 42374), we noted that 
effective with FY 2022 and forward, CMS changed the name of this 
adjustment to refer to it as the productivity adjustment rather than 
the MFP adjustment.
    As stated in the proposed rule, using IGI's fourth quarter 2024 
forecast, the 10-year moving average growth of TFP for FY 2026 was 
projected to be 0.8 percent. In accordance with section 1886(j)(3)(C) 
of the Act, we proposed to base the FY 2026 IRF market basket 
percentage increase, which is used to determine the applicable 
percentage increase for the IRF payments, on IGI's fourth quarter 2024 
forecast of the 2021-based IRF market basket. We proposed to then 
reduce the market basket percentage increase by the proposed 
productivity adjustment for FY 2026 of 0.8 percentage point (the 10-
year moving average growth of TFP for the period ending FY 2026 based 
on IGI's fourth quarter 2024 forecast). Therefore, the proposed FY 2026 
IRF market basket update was 2.6 percent (3.4 percent market basket 
percentage increase reduced by the 0.8 percentage point productivity 
adjustment). Furthermore, we proposed that if more recent data became 
available after the publication of the proposed rule and before the 
publication of this final rule (for example, a more recent estimate of 
the market basket percentage increase and productivity adjustment), we 
would use such data, if appropriate, to determine the FY 2026 IRF 
market basket percentage increase and productivity adjustment in this 
final rule.
    Using IGI's second quarter 2025 forecast, the 10-year moving 
average growth of TFP for FY 2026 is projected to be 0.7 percent. Thus, 
in accordance with section 1886(j)(3)(C) of the Act, the FY 2026 market 
basket percentage increase, which is used to determine the applicable 
percentage increase for the IRF payments, is equal to 3.3 percent using 
IGI's second quarter 2025 forecast of the 2021-based IRF market basket. 
We then reduce this percentage increase by the estimated productivity 
adjustment for FY 2026 of 0.7 percentage point (the 10-year moving 
average growth of TFP for the period ending FY 2026 based on IGI's 
second quarter 2025 forecast). Therefore, more recent data would 
provide a FY 2026 IRF update equal to 2.6 percent (3.3 percent market 
basket percentage increase reduced by the 0.7 percentage point 
productivity adjustment).
    In its March 2025 Report to Congress, MedPAC recommended that 
Congress should reduce the IRF PPS base payment rate by 7 percent for 
FY 2026.\4\ As discussed, and in accordance with sections 1886(j)(3)(C) 
and 1886(j)(3)(D) of the Act, the Secretary proposed to update the IRF 
PPS payment rates for FY 2026 by the proposed IRF market basket update 
of 2.6 percent.
---------------------------------------------------------------------------

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

    Based on more recent data, the current estimate of the 
productivity-adjusted IRF market basket increase factor for FY 2026 
remains 2.6 percent. Section 1886(j)(3)(C) of the Act does not provide 
the Secretary with the authority to apply a different update factor to 
IRF PPS payment rates for FY 2026.
    We invited public comments on the proposed FY 2026 market basket 
percentage increase and productivity adjustment. The following is a 
summary of the public comments received and our responses.

[[Page 37689]]

    Comment: Several commenters expressed agreement with the general 
strategy of increasing the standard payment conversion factor. However, 
many raised concerns that the proposed FY 2026 IRF payment increase is 
insufficient. Respondents indicated that the proposed payment 
adjustment fails to keep up with the significant cost increases faced 
by IRFs, including those related to labor, drugs, medical supplies, 
personal protective equipment (PPE), and capital investments. 
Additionally, they highlighted other challenges such as staffing 
shortages, supply chain disruptions, escalating cybersecurity 
investment needs, higher administrative costs due to MA and commercial 
plan practices, and uncertain inflation expectations resulting from 
recent and proposed tariff adjustments on goods like medical supplies 
and pharmaceuticals from key supplier countries.
    Several commenters mentioned that the increasing disparity between 
payment inflation and cost inflation is exerting significant financial 
pressure on hospitals, leading to a substantial reduction in their 
profit margins. A few commenters have expressed that an analysis of the 
data in CMS' IRF Rate-Setting File suggests that nearly 40 percent of 
all IRFs are projected to experience negative total PPS profit margins 
for FY 2025, including over half of hospital-based IRF units and 
teaching IRFs. Additionally, one commenter referred to MedPAC's March 
2025 Report to Congress, which highlighted that non-profit IRFs tend to 
have lower profit margins compared to for-profit IRFs. The report 
recommends that Congress reduce the IRF base payment by 7 percent for 
FY 2026. However, the commenter suggested that this recommendation 
might not be applicable if the analysis had distinctly considered for-
profit and non-profit IRFs, as non-profit IRFs typically exhibit 
smaller profit margins. One commenter, MedPAC, stated that the 
Secretary is required to update the IRF PPS rates by the market basket 
minus a productivity adjustment; however, based on the review of many 
payment adequacy indicators, including beneficiary access to IRF 
services, the supply of providers, and aggregate IRF Medicare margins 
(which have been above 13 percent since 2015), the Commission concluded 
that Medicare's current payment rates for IRFs are more than adequate.
    Most commenters highlighted that persistent labor shortages and 
high-cost inflation necessitate increased payment rates for all IRFs. 
They urged CMS to consider the most current inflation data or update 
the market basket to reflect actual input costs. One commenter noted 
that rural IRFs face even more cost pressures amplified by severe 
workforce shortages, heavy dependence on traveling clinicians and 
contract staff, lack of community-based alternatives leading to longer 
patient stays, and significant transportation and access issues.
    Several commenters indicated that the underlying construction of 
the IRF market basket may have limitations that do not adequately 
capture inflation pressures. They stated that it is perplexing how 
hospitals, especially labor-intensive IRFs, could experience a change 
in the market basket that is significantly below general inflation. The 
commenters noted that the IRF market basket relies on projected growth 
in generalized hospital goods and services, which does not consider the 
specialized training and experience required by therapists, nurses, and 
other clinicians in IRFs. Additionally, some commenters highlighted 
that IRFs often incur higher costs for advanced rehabilitation 
technologies and specialized medications, which may not be adequately 
reflected in the market basket. An example the commenter provided was 
CMS' use of the Employment Cost Index (ECI) to measure changes in labor 
compensation in the market basket. The commenters stated that the ECI 
might not fully capture growth in employment and labor costs, as it 
does not account for changes driven by shifts between different 
categories of labor. However, the commenters emphasized that this is 
just one potential issue and encouraged CMS to comprehensively 
reexamine the market basket to identify other areas for refinement.
    Several commenters suggested that CMS review the current 
forecasting approach used for determining the IRF PPS market basket 
update, indicating there may be a systemic issue with IGI's forecasting 
that tends toward under-forecasting growth. They observed that since 
the COVID-19 PHE, IGI's forecasted growth for the IRF market basket has 
consistently been lower than the actual market basket growth. While 
acknowledging that forecasts are inherently imperfect, they asserted 
that past forecasts were more balanced. The commenters expressed 
concern that without action from CMS, these missed forecasts will 
become permanently embedded in the standard payment rate for IRFs and 
will continue to accumulate. Additionally, they pointed out that these 
underpayments affect other payments as well, including those for the 
growing MA patient population and commercial insurer payment rates. 
Some commenters mentioned that CMS has provided larger increases to MA 
plans, such as a recent 5.06 percent rate increase for 2026, and 
questioned why there is a significant difference between the MA rate 
increase and the IRF FFS rate increase. One commenter noted that the 
authorizing statute for the IRF PPS allows CMS to determine a suitable 
index for the market basket update and to make appropriate adjustments 
to IRF PPS payments and this implies that CMS is not required to use 
IGI data, or solely such data, as the basis for the IRF PPS increase 
factor.
    Response: We acknowledge and appreciate commenters' concerns 
regarding recent trends in inflation. We are required to update IRF PPS 
payments by the market basket update adjusted for productivity, as 
directed by section 1886(j)(3)(C) of the Act. Specifically, section 
1886(j)(3)(C)(i) of the Act states that the increase factor shall be 
based on an appropriate percentage increase in a market basket of goods 
and services comprising services for which payment is made. In the FY 
2024 IRF PPS final rule, we rebased the IRF market basket to reflect a 
2021 base year (88 FR 50966 through 50982). We believe the increase in 
the 2021-based IRF market basket adequately reflects the average change 
in the price of goods and services hospitals purchase to provide IRF 
medical services and is technically appropriate to use as the IRF 
payment update factor.
    The IRF market basket is a fixed-weight, Laspeyres-type index that 
measures the change in price over time of the same mix of goods and 
services purchased by IRFs in the base period. As we discussed in 
response to similar comments in the FY 2024 IRF PPS final rule (88 FR 
50983) and the FY 2025 IRF PPS final rule (89 FR 64286), the IRF market 
basket update would reflect the prospective price pressures described 
by the commenters as increasing during a high inflation period but 
would inherently not reflect other factors that might increase the 
level of costs (such as increases in volume or intensity). We note that 
cost changes (that is, the product of price and quantities) would only 
be reflected when a market basket is rebased, and the base year weights 
are updated to a more recent time period.
    We respectfully disagree that the IRF market basket does not 
consider the specialized costs faced by IRFs, as the market basket 
weights are derived directly from IRF cost report data, which 
inherently captures and reflects the specific cost structures of 
inpatient rehabilitation facilities, including expenditures for 
specialized

[[Page 37690]]

rehabilitation technologies, advanced therapeutic equipment, and the 
unique staffing mix required for IRF services, ensuring that these 
facility-specific costs are appropriately represented in the market 
basket calculation. Additionally, we note that the IRF market basket is 
designed to reflect national-level inflationary price pressures 
affecting IRFs, and separate payment adjustments, such as rural add-on 
payments and wage index adjustments, exist to address geographic cost 
variations and specific challenges faced by rural facilities. 
Therefore, we believe the 2021-based IRF market basket appropriately 
reflects IRF cost structures.
    To measure price growth for IRF wages and salaries costs in the IRF 
market basket, since IRF-specific information is unavailable, we use 
the ECI for Wages and Salaries for All Civilian workers in Hospitals. 
As stated in the FY 2024 IRF final rule (88 FR 50978) and FY 2025 IRF 
final rule (89 FR 64286), we believe that this ECI is the best 
available price proxy to account for the occupational skill mix within 
IRFs and in the absence of an IRF-specific ECI, we believe that the 
highly skilled hospital workforce captured by the ECI for Wages and 
Salaries for All Civilian workers in Hospitals (inclusive of 
therapists, nurses, other clinicians, etc.) is a reasonable price proxy 
for the compensation component of the IRF market basket. The FY 2024 
IRF and FY 2025 IRF final rules provide a detailed discussion as it 
relates to contract labor in IRFs and their share of overall IRF 
compensation costs and hours.
    To reflect expected price growth for each of the cost categories in 
the IRF market basket, we rely on impartial economic forecasts of the 
price proxies used in the market basket from IGI, which is a nationally 
recognized economic and financial forecasting firm with which CMS 
contracts to forecast the components of the market baskets. At the time 
of the FY 2026 IRF PPS proposed rule, based on IGI's fourth quarter 
2024 forecast with historical data through the third quarter of 2024, 
the 2021-based IRF market basket update was forecasted to be 3.4 
percent for FY 2026, reflecting forecasted compensation price growth of 
3.6 percent. We also note that when developing its forecast for labor 
prices, IGI considers overall labor market conditions (including rise 
in contract labor employment due to tight labor market conditions) as 
well as trends in contract labor wages, which both have an impact on 
wage pressures for workers employed directly by the hospital.
    As is our general practice, in the FY 2026 IRF PPS proposed rule, 
we proposed that if more recent data became available, we would use 
such data, if appropriate, to derive the final FY 2026 IRF market 
basket update for the final rule. For this final rule, we now have an 
updated forecast of the price proxies underlying the market basket that 
incorporates more recent historical data and reflects a revised outlook 
regarding the U.S. economy and expected price inflation for FY 2026. 
Based on IGI's second quarter 2025 forecast with historical data 
through the first quarter of 2025, we are projecting a FY 2026 IRF 
market basket percentage increase of 3.3 percent (reflecting forecasted 
compensation price growth of 3.4 percent). Based on IGI's second 
quarter 2025 forecast, we are also projecting a productivity adjustment 
of 0.7 percentage point. Therefore, for FY 2026 a final IRF 
productivity-adjusted market basket update of 2.6 percent (3.3 percent 
less 0.7 percentage point) will be applicable, this update is unchanged 
from the proposed IRF market basket update of 2.6 percent. We note that 
the final FY 2026 IRF market basket increase is slightly lower than in 
the proposed rule (by 0.1 percentage point) reflecting economic 
uncertainty. Additionally, the expectation for slower economic growth 
contributes to a slightly lower productivity adjustment for FY 2026.
    CMS understands that the market basket updates may differ from 
other overall inflation indexes such as the topline CPI; however, we 
would reiterate that these topline indexes are not comparable since 
they measure different mixes of products, services, or wages than the 
IRF market basket. Additionally, the market basket updates 
appropriately differ from other payment updates (such as projected 
increase in the average per capita payments to Medicare Advantage 
organizations) that are not consistent in concept with the statutory 
requirement as they would reflect anticipated volume and intensity of 
services.
    Regarding whether IRF PPS payments are adequate to cover costs, 
MedPAC's analysis and recommendations as published in MedPAC's March 
2025 \5\ Report to Congress concluded that Medicare's current payment 
rates for IRFs are more than adequate based on aggregate Medicare 
margins above 13 percent since 2015. With respect to the commenters' 
concern about payments to non-profits, MedPAC acknowledged that margins 
continued to vary widely across types of IRFs, with higher margins in 
IRFs that were freestanding, for profit, urban, larger, and with a 
greater share of FFS Medicare days.

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

    We do not have statutory authority to vary payment under the IRF 
PPS according to non-profit status but are continuing to explore 
changes to the IRF PPS within our regulatory authority, such as 
alternative approaches to case mix groups (replacing the hospital-
specific relative value weighting with average cost weighting), which 
has been recommended by MedPAC's 2024 Report to Congress.\6\

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

    Finally, we acknowledge the commenter's recommendation that we 
reexamine the market basket to identify other potential areas for 
refinement. We will continue to review the IRF market basket, and any 
future changes will be proposed in rulemaking.
    Comment: Several commenters recommended that we not apply the 
productivity adjustment. One commenter urged CMS to consider its 
regulatory authority to modify the productivity adjustment or make a 
PHE- and inflation-related exception in its application for the FY 2026 
update. Additionally, one commenter requested a temporary suspension of 
the productivity adjustment to the IRF market basket due to recent 
declines in hospital productivity. A commenter asserted an imbalance 
between economy-wide productivity measures and IRF-specific 
productivity changes, encouraging CMS to explore all available avenues 
within the agency's existing authority to provide additional financial 
relief for IRFs. Other commenters requested that CMS carefully monitor 
the impact of these productivity adjustments on the rehabilitation 
hospital sector, provide feedback to Congress as appropriate, and 
reduce the productivity adjustment.
    Response: Section 1886(j)(3)(C)(ii)(I) of the Act requires the 
application of the productivity adjustment, described in section 
1886(b)(3)(B)(xi)(II), to the IRF PPS market basket increase factor. As 
required by statute, the FY 2026 productivity adjustment is derived 
based on the 10-year moving average growth in economy-wide, private 
nonfarm business total factor productivity for the period ending FY 
2026. We recognize the concerns of the commenters regarding the 
appropriateness of the productivity adjustment; however, as we 
explained in response to similar comments in the

[[Page 37691]]

FY 2023, FY 2024 and FY 2025 IRF PPS final rules, we are required under 
section 1886(j)(3)(C)(ii)(I) of the Act to apply the specific 
productivity adjustment described here.
    We have always made available on the CMS website the general method 
for calculating the productivity adjustment. This includes providing a 
link (<a href="http://www.bls.gov/productivity">http://www.bls.gov/productivity</a>/) to the most recent BLS 
historical TFP data, which allows interested parties to obtain 
historical TFP annual index levels for 1987 through 2024. We also 
provided the IGI projection model (<a href="https://www.cms.gov/research-statistics-data-and-systems/statistics-trends-and-reports/medicareprogramratesstats/downloads/tfp_methodology.pdf">https://www.cms.gov/research-statistics-data-and-systems/statistics-trends-and-reports/medicareprogramratesstats/downloads/tfp_methodology.pdf</a>), which is used 
to derive annual TFP growth rates for 2025 and 2026. The annual index 
level derived from this method is then interpolated to quarterly 
levels, and the FY 2026 productivity adjustment is equal to the percent 
change in the 40-quarter moving average projected level for the period 
ending September 30, 2026, relative to the 40-quarter moving average 
projected level for the period ending September 30, 2025. We believe 
our methodology for the productivity adjustment is consistent with 
section 1886(b)(3)(B)(xi)(II) of the Act, which states that the 
productivity adjustment is equal to the 10-year moving average of 
changes in annual economy-wide private nonfarm business multi-factor 
productivity (as projected by the Secretary for the 10-year period 
ending with the applicable fiscal year, year, cost reporting period, or 
other annual period).
    At the time of this final rule, the FY 2026 productivity adjustment 
reflects BLS historical TFP data through 2024 (released on March 21, 
2025) and IGI's forecasted TFP growth for 2025 and 2026. The average 
annual growth rate of historical TFP published by BLS for 2017 through 
2024 is currently 0.9 percent and IGI is projecting average TFP growth 
of about 0.0 percent for 2025 and 2026 based on IGI's second-quarter 
2025 forecast. Combining the historical and projected TFP data over the 
entire 10-year time period results in a compound annual growth rate of 
TFP of 0.7 percent for 2026. The productivity adjustment (based on the 
10-year period ending with FY 2026) for the FY 2026 IRF final rule is 
0.1 percentage point lower than in the FY 2026 IRF proposed rule and 
primarily reflects the incorporation of a revised outlook from IGI that 
has lower projected economic growth over 2025 and 2026. The 0.7 percent 
productivity adjustment in the FY 2026 final rule is larger than the 
productivity adjustment in prior final rules for FY 2023 and 2024 
mainly due to the incorporation of updated BLS historical data.
    In response to commenters' concerns about the productivity 
adjustment only being applied if it reduces the payment update, we note 
that the productivity adjustment was established under the Affordable 
Care Act with a specific policy intent to encourage efficiency 
improvements in healthcare delivery by linking Medicare payment updates 
to economy-wide productivity gains. The statutory language in section 
1886(j)(3)(C)(ii) of the Act requires that the Secretary reduce (not 
increase) the market basket percentage increase by changes in economy-
wide productivity, therefore, only positive productivity adjustments 
are applied.
    Comment: Many commenters have noted concerns about CMS's estimation 
of the IRF market basket updates since the COVID-19 pandemic, stating 
that it has resulted in underpayments to IRF providers. Organizations 
report cumulative underpayments between 3.5 to 4.6 percentage points 
for fiscal years 2021 to 2024, with an annual financial impact of 
approximately $450 million, highlighting discrepancies between 
forecasted and actual market basket rates. Commenters suggest that CMS 
address these forecast errors as it does in the Skilled Nursing 
Facility (SNF) Prospective Payment System and recommend extending this 
approach to IRFs. Most organizations are requesting a retrospective 
adjustment of 3.5 to 4.6 percentage points for FY 2026, along with 
policy changes for ongoing forecast error correction mechanisms like 
the SNF PPS.
    Concerns have been raised about the IGI forecasting methodology, 
which is perceived to lean towards under-forecasting in the post-
pandemic environment. Commenters highlight that inadequate 
reimbursement may affect patient access to rehabilitation services and 
challenge the long-term stability of IRF providers, potentially causing 
care disruptions. According to the commenters, without correction, 
these forecast errors become embedded in future payment rates, widening 
the gap between actual costs and reimbursement. The consensus among 
commenting organizations is that CMS should implement a one-time market 
basket adjustment for FY 2026 to account for the cumulative 
underpayments due to market basket forecast errors from recent years 
and establish mechanisms to prevent similar issues in the future. 
Commenters assert that CMS has the statutory and regulatory authority 
to make these adjustments, given the precedent set in the SNF payment 
system and the agency's general authority over market basket 
calculations.
    Response: The IRF market basket updates are set prospectively, 
which means that the update relies on a mix of both historical data for 
part of the period for which the update is calculated and forecasted 
data for the remainder. For instance, the FY 2026 market basket update 
in this final rule reflects historical data through the first quarter 
of CY 2025 and forecasted data through the third quarter of CY 2026.
    The forecast error has been both positive and negative during past 
years, and over longer periods of time the cumulative forecast has not 
deviated significantly from the historical measures. Only considering 
the forecast error for years when the IRF market basket update was 
lower than the actual market basket update would not fully account for 
forecast error. After careful consideration of public comments, we are 
finalizing a FY 2026 IRF productivity-adjusted market basket increase 
of 2.6 percent based on the most recent data available. This reflects a 
3.3 percent market basket percentage increase, less the 0.7 percentage 
point productivity adjustment required by law.

C. Labor-Related Share for FY 2026

    Section 1886(j)(6) of the Act specifies that the Secretary is to 
adjust the proportion (as estimated by the Secretary from time to time) 
of IRFs' costs that are attributable to wages and wage-related costs, 
of the prospective payment rates computed under section 1886(j)(3) of 
the Act, for area differences in wage levels by a factor (established 
by the Secretary) reflecting the relative hospital wage level in the 
geographic area of the rehabilitation facility compared to the national 
average wage level for such facilities. The labor-related share is 
determined by identifying the national average proportion of total 
costs that are related to, influenced by, or vary with the local labor 
market. We proposed to continue to classify a cost category as labor-
related if the costs are labor-intensive and vary with the local labor 
market.
    Based on our definition of the labor-related share and the cost 
categories in the 2021-based IRF market basket, we proposed to 
calculate the labor-related share for FY 2026 as the sum of the FY 2026 
relative importance of Wages and Salaries, Employee Benefits, 
Professional Fees: Labor-Related, Administrative and Facilities Support 
Services, Installation, Maintenance, and Repair Services, All Other: 
Labor-

[[Page 37692]]

Related Services, and a portion of the Capital-Related relative 
importance from the 2021-based IRF market basket. For more details 
regarding the methodology for determining specific cost categories for 
inclusion in the 2021-based IRF labor-related share, see the FY 2024 
IRF PPS final rule (88 FR 50985 through 50988).
    The relative importance reflects the different rates of price 
change for these cost categories between the base year (2021) and FY 
2026. We calculate the labor-related relative importance from the IRF 
market basket, and it approximates the labor-related portion of the 
total costs after taking into account historical and projected price 
changes between the base year and FY 2026. The price proxies that move 
the different cost categories in the market basket do not necessarily 
change at the same rate, and the relative importance captures these 
changes. Based on IGI's fourth quarter 2024 forecast of the 2021-based 
IRF market basket, the sum of the FY 2026 relative importance for Wages 
and Salaries, Employee Benefits, Professional Fees: Labor-Related, 
Administrative and Facilities Support Services, Installation 
Maintenance & Repair Services, and All Other: Labor-Related Services 
was 70.8 percent. We proposed that the portion of Capital-Related costs 
that are influenced by the local labor market is 46 percent. Since the 
relative importance for Capital-Related costs was 8.1 percent of the 
2021-based IRF market basket for FY 2026, we proposed to take 46 
percent of 8.1 percent to determine the labor-related share of Capital-
Related costs for FY 2026 of 3.7 percent. Therefore, we proposed a 
total labor-related share for FY 2026 of 74.5 percent (the sum of 70.8 
percent for the proposed labor-related share of operating costs and 3.7 
percent for the proposed labor-related share of Capital-Related costs). 
We also proposed that if more recent data subsequently became available 
after publication of the proposed rule and before the publication of 
this final rule (for example, a more recent estimate of the labor-
related share), we would use such data, if appropriate, to determine 
the FY 2026 IRF labor-related share in this final rule.
    Based on IGI's second quarter 2025 forecast for the 2021-based IRF 
market basket, the sum of the FY 2026 relative importance for Wages and 
Salaries, Employee Benefits, Professional Fees: Labor-related, 
Administrative and Facilities Support Services, Installation 
Maintenance & Repair Services, and All Other: Labor-Related Services is 
70.7 percent. The portion of Capital-Related costs that is influenced 
by the local labor market is estimated to be 46 percent, which is the 
same percentage applied to the 2016-based IRF market basket (84 FR 
39088 through 39089). Since the relative importance for Capital is 8.1 
percent of the 2021-based IRF market basket in FY 2026, we took 46 
percent of 8.1 percent to determine the labor-related share of Capital-
Related costs for FY 2026 of 3.7 percent. Therefore, the total labor-
related share for FY 2026 based on more recent data is 74.4 percent 
(the sum of 70.7 percent for the operating costs and 3.7 percent).
    We invited public comments on the proposed labor-related share for 
FY 2026.
    The following is a summary of the public comments received and our 
responses.
    Comment: One commenter stated that the proposed 0.1 percent 
increase to the labor-related share is inadequate in the context of the 
current economic climate of rising labor costs, inflationary pressures, 
and workforce shortages. The commenter respectfully requests that CMS 
reconsider the proposed labor-related share allocations to ensure they 
more accurately reflect the increased resource requirements necessary 
to maintain compliance and sustain high-quality patient care.
    Response: We proposed to use the FY 2026 relative importance values 
for the labor-related cost categories from the 2021-based IRF market 
basket because it accounts for more recent data regarding price 
pressures and cost structure of IRFs. This methodology is consistent 
with the determination of the labor-related share since the 
implementation of the IRF PPS. As stated in the FY 2026 IRF proposed 
rule, we also proposed that if more recent data became available, we 
would use such data, if appropriate, to determine the FY 2026 labor-
related share for the final rule. Based on IGI's second quarter 2025 
forecast with historical data through the first quarter of 2025, the FY 
2026 labor-related share for the final rule is 74.4 percent, reflecting 
expectations of a slight softening of the labor market cost pressures 
since the proposed rule forecast. We note the FY 2026 labor-related 
share is unchanged from the FY 2025 labor-related share. After 
consideration of the public comments we received, we are finalizing a 
FY 2026 labor-related share of 74.4 percent.

the FY 2025 final labor-related share using the 2021-based IRF market 
basket relative importance.

D. Wage Adjustment for FY 2026

1. Background
    Section 1886(j)(6) of the Act requires the Secretary to adjust the 
proportion of rehabilitation facilities' costs attributable to wages 
and wage-related costs (as estimated by the Secretary from time to 
time) by a factor (established by the Secretary) reflecting the 
relative hospital wage level in the geographic area of the 
rehabilitation facility compared to the national average wage level for 
those facilities. The Secretary is required to update the IRF PPS wage 
index on the basis of information available to the Secretary on the 
wages and wage-related costs to furnish rehabilitation services. Any 
adjustments or updates made under section 1886(j)(6) of the Act for a 
FY are made in a budget-neutral manner.
    In the FY 2023 IRF PPS final rule (87 FR 47054 through 47056) we 
finalized a policy to apply a 5-percent cap on any decrease to a 
provider's wage index from its wage index in the prior year, regardless 
of the circumstances causing the decline. We amended IRF PPS 
regulations at Sec.  412.624(e)(1)(ii) to reflect this permanent cap on 
wage index decreases. Additionally, we finalized a policy that a new 
IRF would be paid the wage index for the area in which it is 
geographically located for its first full or partial FY with no cap 
applied because a new IRF would not have a wage index in the prior FY. 
A full discussion of the adoption of this policy is found in the FY 
2023 IRF PPS final rule.
    For FY 2026, we proposed to maintain the policies and methodologies 
described in the FY 2025 IRF PPS final rule (89 FR 64276) related to 
the labor market area definitions and the wage index methodology for 
areas with wage data. Thus, we use the core based statistical areas 
(CBSAs) labor market area definitions and the FY 2026 pre-
reclassification and pre-floor hospital wage index data. In accordance 
with section 1886(d)(3)(E) of the Act, the FY 2026 pre-reclassification 
and pre-floor hospital wage index is based on data submitted for 
hospital cost reporting periods beginning on or after October 1, 2021, 
and before October 1, 2022 (that is, FY 2022 cost report data).
    In addition, we will continue to use the same methodology discussed 
in the FY 2008 IRF PPS final rule (72 FR 44299) to address those 
geographic areas in which there are no hospitals and, thus, no hospital 
wage index data on which to base the calculation for the FY 2026 IRF 
PPS wage index. For FY 2026, the only rural area without wage index 
data available is in North Dakota. For urban areas without specific 
hospital wage index data, we will continue using the average wage 
indexes of all urban areas within the State to serve as a reasonable 
proxy for the wage index of that urban CBSA as proposed and finalized 
in FY 2006 (70 FR 47927). For FY 2026, the only urban area without wage 
index data available is CBSA 25980, Hinesville Fort Stewart, Georgia.
    We invited public comments on our proposals regarding the Wage 
Adjustment for FY 2026.
    The following is a summary of the public comments received and our 
responses on the proposed revisions to the Wage Adjustment for FY 2026.
    Comment: Many commenters supported the existing 5 percent wage 
index cap and expressed appreciation of having a policy to cap and 
phase in the wage index changes that a provider can experience in a 
given year. One commenter expressed frustration that the wage index 
values of the hospitals subject to the cap differ from the currently 
published tables and urged CMS to release wage index tables in the 
final rule that incorporates the cap on Core Based Statistical Areas 
(CBSAs) that meet the 5 percent decrease criteria.
    Response: We appreciate the commenters' support of the permanent 
cap on wage index decreases. We realize that the 5-percent cap on 
annual decreases in the wage index values does not entirely eliminate 
the effects of annual changes in the wage index, but we believe that it 
does substantially reduce the financial impact on IRFs of these annual 
changes. The wage index tables for IRF PPS are provided at the CBSA 
level. The 5-percent cap policy is applied at the provider level. 
Hence, when the 5-percent cap is applicable, each IRF should work 
directly with its Medicare Administrative Contractor (MAC) to 
understand how the 5-percent cap is applied. MACs have more detailed 
information about the location of each IRF and the applicability of the 
5-percent cap to each IRFs situation, and CMS has provided careful 
instructions to the MACs on applying the 5-percent cap policy (see 
publication 100-04 Medicare Claims Processing Manual, Chapter 3).
    Comment: Multiple commenters urged CMS to refine the wage index 
calculations to create parity across provider types in the same market 
areas. They expressed concern over the use of the pre-classification 
and pre-floor IPPS wage index. They noted that since IPPS hospitals can 
reclassify their wage indices, acute care hospitals across the country 
are receiving wage index increases higher than would be assigned their 
Core Based Statistical Areas (CBSAs). One commenter also voiced 
concerns that IPPS hospitals that have benefited from IPPS-specific 
geographic reclassification or other wage adjustments no longer put the 
same resources into the completion of Occupational Mix Surveys. One 
commenter highlighted rural and low- wage index IRFs are particularly 
disadvantaged by the use of the pre-floor IPPS wage index.
    Another commenter noted IRF distinct part units (DPUs) are 
particularly impacted by this and urged CMS to leverage existing data 
to evaluate the policy change using the CMS Form 2552-96, Worksheet S-
3, which captures ``excluded area'' salaries and wage-related costs. 
They urged CMS to also reconsider its policy on the out-migration 
adjustment application to IRF DPUs as they noted they face the same 
challenges in the marketplace as IPPS hospitals. Another commenter 
suggested that CMS utilize more up to date cost reports to calculate 
the IRF PPS wage index.
    Response: We appreciate the commenters' suggestion to adopt the 
IPPS post-classification and post-floor hospital IPPS wage index and 
other IPPS wage index adjustments for the IRF wage index. We also 
acknowledge and appreciate the commenters' concerns regarding 
competition for labor resulting from different applicable wage index 
policies across different settings of care. While we and other 
interested parties have explored potential alternatives to the current 
wage index system in the past, we are not considering a replacement 
system at this time. These concerns will be taken into consideration 
while we continue to explore future potential wage index reforms and 
monitor IRF wage index policies using the most up to date information.
    As most recently discussed in the FY 2025 IRF PPS final rule (89 FR 
64276), we would like to note that the IRF wage index is derived from 
IPPS wage data, that is, the pre-reclassification and pre-floor 
hospital wage index discussed in section VI. of this final rule. As 
such, any effects of this policy on the wage data of IPPS hospitals 
would be extended to the IRF setting, as this data would be used to 
establish the wage index for IRFs in the future. We note that IPPS wage 
index values are based on historical data and typically lag by 4 years.
    As stated in prior years, as we do not have an IRF-specific wage 
index, we are unable to determine the degree, if any, to which these 
IPPS policies under the IRF PPS would be appropriate. However, we 
acknowledge that

[[Page 37694]]

commenters have suggested that such data may be available in CMS Form 
2552-96, Worksheet S-3 and will take this into consideration. Data 
pertaining to any IPPS policies that are applied to the pre-
reclassification/pre-floor wage index is available in the FY 2025 IRF 
PPS FR (89 FR 64276). A full history of the IRF PPS rules is available 
on the CMS website at <a href="https://www.cms.gov/files/document/irf-regulatory-and-legislative-history.pdf">https://www.cms.gov/files/document/irf-regulatory-and-legislative-history.pdf</a>.
    After consideration of the comments we received, we are finalizing 
our proposals regarding the wage adjustment for FY 2026.
2. Core-Based Statistical Areas (CBSAs) for the FY 2026 IRF Wage Index
    The wage index used for the IRF PPS is calculated using the pre-
reclassification and pre-floor hospital wage index data and is assigned 
to the IRF on the basis of the labor market area in which the IRF is 
geographically located. IRF labor market areas are delineated based on 
the CBSAs established by the OMB. The CBSA delineations (which were 
implemented for the IRF PPS beginning with FY 2016) are based on 
revised OMB delineations issued on February 28, 2013, in OMB Bulletin 
No. 13-01. OMB Bulletin No. 13-01 established- revised delineations for 
Metropolitan Statistical Areas, Micropolitan Statistical Areas, and 
Combined Statistical Areas in the United States and Puerto Rico based 
on the 2010 Census and provided guidance on the use of the delineations 
of these statistical areas using standards published in the June 28, 
2010, Federal Register (75 FR 37246 through 37252). We refer readers to 
the FY 2016 IRF PPS final rule (80 FR 47068 through 47076) for a full 
discussion of our implementation of the OMB labor market area 
delineations beginning with the FY 2016 wage index.
    Generally, OMB issues major revisions to statistical areas every 10 
years, based on the results of the decennial census. Additionally, OMB 
occasionally issues updates and revisions to the statistical areas in 
between decennial censuses to reflect the recognition of new areas or 
the addition of counties to existing areas. In some instances, these 
updates merge formerly separate areas, transfer components of an area 
from one area to another or drop components from an area. On July 15, 
2015, OMB issued OMB Bulletin No. 15-01, which provides minor updates 
to and supersedes OMB Bulletin No. 13-01 that was issued on February 
28, 2013. The attachment to OMB Bulletin No. 15-01 provides detailed 
information on the update to statistical areas since February 28, 2013. 
The updates provided in OMB Bulletin No. 15-01 are based on the 
application of the 2010 Standards for Delineating Metropolitan and 
Micropolitan Statistical Areas to Census Bureau population estimates 
for July 1, 2012, and July 1, 2013.
    In the FY 2018 IRF PPS final rule (82 FR 36250 through 36251), we 
adopted the updates set forth in OMB Bulletin No. 15-01 effective 
October 1, 2017, beginning with the FY 2018 IRF wage index. For a 
complete discussion of the adoption of the updates set forth in OMB 
Bulletin No. 15-01, we refer readers to the FY 2018 IRF PPS final rule. 
In the FY 2019 IRF PPS final rule (83 FR 38527), we continued to use 
the OMB delineations that were adopted beginning with FY 2016 to 
calculate the area wage indexes, with updates set forth in OMB Bulletin 
No. 15-01 that we adopted beginning with the FY 2018 wage index.
    On August 15, 2017, OMB issued OMB Bulletin No. 17-01, which 
provided updates to and superseded OMB Bulletin No. 15-01 that was 
issued on July 15, 2015. The attachments to OMB Bulletin No. 17-01 
provide detailed information on the update to statistical areas since 
July 15, 2015, and are based on the application of the 2010 Standards 
for Delineating Metropolitan and Micropolitan Statistical Areas to 
Census Bureau population estimates for July 1, 2014, and July 1, 2015. 
In the FY 2020 IRF PPS final rule (84 FR 39090 through 39091), we 
adopted the updates set forth in OMB Bulletin No. 17-01 effective 
October 1, 2019, beginning with the FY 2020 IRF wage index.
    On April 10, 2018, OMB issued OMB Bulletin No. 18-03, which 
superseded the August 15, 2017, OMB Bulletin No. 17-01, and on 
September 14, 2018, OMB issued OMB Bulletin No. 18-04, which superseded 
the April 10, 2018 OMB Bulletin No. 18-03. These bulletins established 
revised delineations for Metropolitan Statistical Areas, Micropolitan 
Statistical Areas, and Combined Statistical Areas, and provided 
guidance on the use of the delineations of these statistical areas. A 
copy of this bulletin may be obtained at <a href="https://www.whitehouse.gov/wp-content/uploads/2018/09/Bulletin-18-04.pdf">https://www.whitehouse.gov/wp-content/uploads/2018/09/Bulletin-18-04.pdf</a>.
    To this end, as discussed in the FY 2021 IRF PPS proposed (85 FR 
22075 through 22079) and final (85 FR 48434 through 48440) rules, we 
adopted the revised OMB delineations identified in OMB Bulletin No. 
1804 (available at <a href="https://www.whitehouse.gov/wp-content/uploads/2018/09/Bulletin-18-04.pdf">https://www.whitehouse.gov/wp-content/uploads/2018/09/Bulletin-18-04.pdf</a>) beginning October 1, 2020, including a 1 year 
transition for FY 2021 under which we applied a 5-percent cap on any 
decrease in an IRF's wage index compared to its wage index for the 
prior fiscal year (FY 2020). The updated OMB delineations more 
accurately reflect the contemporary urban and rural nature of areas 
across the country, and the use of such delineations allows us to 
determine more accurately the appropriate wage index and rate tables to 
apply under the IRF PPS. OMB issued further revised CBSA delineations 
in OMB Bulletin No. 20-01, on March 6, 2020 (available on the web at 
<a href="https://www.whitehouse.gov/wp-content/uploads/2020/03/Bulletin-20-01.pdf">https://www.whitehouse.gov/wp-content/uploads/2020/03/Bulletin-20-01.pdf</a>). However, we determined that the changes in OMB Bulletin No. 
20-01 do not impact the CBSA-based labor market area delineations 
adopted in FY 2021. Therefore, we did not propose to adopt the revised 
OMB delineations identified in OMB Bulletin No. 20-01 for FY 2022 
through FY 2024.
    On July 21, 2023, OMB issued OMB Bulletin No. 23-01 (available at 
<a href="https://www.whitehouse.gov/wp-content/uploads/2023/07/OMB-Bulletin-23-01.pdf">https://www.whitehouse.gov/wp-content/uploads/2023/07/OMB-Bulletin-23-01.pdf</a>) which updates and supersedes OMB Bulletin No. 20-01 based upon 
the 2020 Standards for Delineating Core Based Statistical Areas (``the 
2020 Standards'') published by OMB on July 16, 2021 (86 FR 37770). OMB 
Bulletin No. 23-01 revised CBSA delineations that are comprised of 
counties and equivalent entities (for example, boroughs; a city and 
borough; and a municipality in Alaska; planning regions in Connecticut; 
parishes in Louisiana; municipios in Puerto Rico; and independent 
cities in Maryland, Missouri, Nevada, and Virginia). As discussed in 
the FY 2025 IRF PPS final rule (89 FR 64291 through 64304), we adopted 
the revised OMB delineations identified in OMB Bulletin No. 23-01.
3. Second Year of the 3-Year Phase Out of the Rural Adjustment
    For FY 2026, CMS is continuing the 3-year budget-neutral phase-out 
of the rural adjustment for FY 2024 IRFs transitioning from rural to 
urban status in FY 2025 under the revised CBSA delineations. As stated 
in the FY 2025 IRF PPS final rule (89 FR 64276), the purpose of this 
gradual phase-out of the rural adjustment for these facilities is to 
reduce the potential negative financial impacts associated with this 
reclassification. In FY 2026, the second year of this phase-out, 
affected IRFs will receive the full FY 2026 wage index along with one-
third of the FY 2024 rural adjustment. This step is part of a gradual 
reduction of the 14.9 percent rural adjustment over three fiscal years

[[Page 37695]]

-FYs 2025, 2026, and 2027. Furthermore, this policy does not apply to 
urban IRFs transitioning to rural status, as they will receive the full 
rural adjustment.
    The following is a summary of the public comments received and our 
responses on the proposal regarding the second year of the 3-year phase 
out of the rural adjustment.
    Comment: Public comments supported the phase-out policy for IRFs 
being reclassified from rural to urban CBSAs. Commenters expressed that 
this phase-out policy for loss of the rural adjustment is a reasonable 
way to ensure that no IRF faces a dramatic cut to its reimbursement as 
a result of the new CBSA delineation. One commenter urged CMS to 
evaluate whether the policy disproportionately impacts rural IRFs with 
more low-income patients.
    Response: We appreciate the commenters' feedback on the continued 
phase out policy for IRFs reclassification from rural to urban CBSAs. 
We will continue to monitor whether CBSA delineation changes 
disproportionately impact certain provider populations, such as low-
income patients. Separately, the low-income patient (LIP) adjustment 
will continue to be applied because we did not propose to change the 
low-income patient adjustment (LIP) policy at Sec.  412.624(e)(2).
    After consideration of the comments we received, we are finalizing 
our proposal to continue the 3-year budget-neutral phase-out of the 
rural adjustment for FY 2024 IRFs transitioning from rural to urban 
status in FY 2026 under the revised CBSA delineations.
4. IRF Budget-Neutral Wage Adjustment Factor Methodology
    To calculate the wage-adjusted facility payment for the payment 
rates set forth in this rule, we multiply the unadjusted Federal 
payment rate for IRFs by the FY 2026 labor-related share based on the 
2021-based IRF market basket relative importance (74.4 percent) to 
determine the labor-related portion of the standard payment amount. (A 
full discussion of the calculation of the labor-related share appears 
in section VI of this final rule.) We then multiply the labor-related 
portion by the applicable IRF wage index. The wage index tables are 
available on the CMS website at <a href="https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/InpatientRehabFacPPS/IRF-Rules-and-Related-Files.html">https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/InpatientRehabFacPPS/IRF-Rules-and-Related-Files.html</a>.
    Adjustments or updates to the IRF wage index made under section 
1886(j)(6) of the Act must be made in a budget-neutral manner. We 
calculate a budget-neutral wage adjustment factor as established in the 
FY 2004 IRF PPS final rule (68 FR 45689) and codified at Sec.  
412.624(e)(1), as described in the steps below. We use the listed steps 
to ensure that the FY 2026 IRF standard payment conversion factor 
reflects the update to the wage indexes (based on the FY 2022 hospital 
cost report data) and the update to the labor-related share, in a 
budget-neutral manner:
    Step 1. Calculate the total amount of estimated IRF PPS payments 
using the labor-related-share and the wage indexes from FY 2025 (as 
published in the FY 2025 IRF PPS final rule (89 FR 64276)).
    Step 2. Calculate the total amount of estimated IRF PPS payments 
using the FY 2026 wage index values (based on updated hospital wage 
data and taking into account the permanent 5-percent cap on wage index 
decreases when applicable) and the FY 2026 labor-related share of 74.4 
percent.
    Step 3. Divide the amount calculated in Step 1 by the amount 
calculated in Step 2. The resulting quotient is the proposed FY 2026 
budget-neutral wage adjustment factor of 1.0001.
    Step 4. Apply the budget neutrality factor from Step 3 to the FY 
2026 IRF PPS standard payment amount after the application of the 
market basket percentage increase to determine the FY 2026 standard 
payment conversion factor.
    We discuss the calculation of the standard payment conversion 
factor for FY 2026 in section VI.E. of this final rule.
    We invited public comments on our proposals regarding the Wage 
Adjustment for FY 2026.
    The following is a summary of the public comments received and our 
responses to the proposed revisions to the Wage Adjustment for FY 2026:
    Comment: Several commenters specified that the wage index cap 
policy should be implemented without applying a budget neutrality 
adjustment.
    Response: We do not believe that the permanent 5-percent cap policy 
for the IRF wage index should be applied in a non-budget-neutral 
manner. The statute at section 1886(j)(6) of the Act requires that 
adjustments for geographic variations in labor costs for a FY be made 
in a budget-neutral manner. We refer readers to the FY 2023 IRF PPS 
final rule (87 FR 47054 through 47056) for a detailed discussion on the 
wage index cap policy.
    After consideration of the comments we received, we are finalizing 
our proposals regarding the IRF budget neutral wage adjustment factor 
methodology for FY 2026 without modification.

E. Description of the IRF Standard Payment Conversion Factor 
Methodology and Payment Rates for FY 2026

    To calculate the IRF standard payment conversion factor for FY 
2026, as illustrated in Table 5, we begin by applying the IRF market 
basket update for FY 2026, as adjusted in accordance with sections 
1886(j)(3)(C) of the Act, to the standard payment conversion factor for 
FY 2025 ($18,907). Applying the 2.6 percent IRF market basket update 
for FY 2026 to the standard payment conversion factor for FY 2025 of 
$18,907 yields a FY 2026 standard payment amount of $19,399. Then, we 
apply the budget neutrality factor for the FY 2026 wage index (taking 
into account the policy placing a permanent 5-percent cap on decreases 
to a provider's wage index), and labor-related share of 1.0001, which 
results in an IRF standard payment amount of $19,401. We next apply the 
budget neutrality factor for the CMG relative weights of 0.9985, which 
results in the IRF standard payment conversion factor of $19,371 for FY 
2026.
    We received no comments on the proposed FY 2026 IRF standard 
payment conversion factor methodology and are finalizing the FY 2026 
IRF standard payment conversion factor methodology as proposed.

F. Example of the Methodology for Adjusting the Prospective Payment 
Rates

    Table 7 illustrates the methodology for adjusting the prospective 
payments (as described in section V of this final rule). The following 
examples are based on two hypothetical Medicare beneficiaries, both 
classified as CMG 0104 (without comorbidities). The unadjusted 
prospective payment rate for CMG 0104 (without comorbidities) appears 
in Table 6.
    Example: One beneficiary is in Facility A, an IRF located in rural 
Spencer County, Indiana, and another beneficiary is in Facility B, an 
IRF located in urban Harrison County, Indiana. Facility A, a rural non-
teaching hospital has a Disproportionate Share Hospital (DSH) 
percentage of 5 percent (which would result in a LIP adjustment of 
1.0156), a wage index of 0.8565, and a rural adjustment of 14.9 
percent. Facility B, an urban teaching hospital, has a DSH percentage 
of 15 percent (which would result in a LIP adjustment of 1.0454), a 
wage index of 0.9145, and a teaching status adjustment of 0.0784.
    To calculate each IRF's labor and non-labor portion of the 
prospective payment, we begin by taking the FY 2026 unadjusted 
prospective payment rate for CMG 0104 (without comorbidities) from 
Table 6. Then, we multiply the labor-related share for FY 2026 (74.4 
percent) described in section VI of this final rule by the unadjusted 
prospective payment rate. To determine the non-labor portion of the 
prospective payment rate, we subtract the labor portion of the Federal 
payment from the unadjusted prospective payment.
    To compute the wage-adjusted prospective payment, we multiply the 
labor portion of the Federal payment by the appropriate wage index 
located in the applicable wage index table. This table is available on 
the CMS website at <a href="https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/InpatientRehabFacPPS/IRF-Rules-and-Related-Files.html">https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/InpatientRehabFacPPS/IRF-Rules-and-Related-Files.html</a>.
    The resulting figure is the wage-adjusted labor amount. Next, we 
compute the wage-adjusted Federal payment by adding the wage-adjusted 
labor amount to the non-labor portion of the Federal payment.
    Adjusting the wage-adjusted Federal payment by the facility-level 
adjustments involves several steps. First, we take the wage-adjusted 
prospective payment and multiply it by the appropriate rural and LIP

[[Page 37698]]

adjustments (if applicable). Second, to determine the appropriate 
amount of additional payment for the teaching status adjustment (if 
applicable), we multiply the teaching status adjustment (0.0784, in 
this example) by the wage-adjusted and rural-adjusted amount (if 
applicable). Finally, we add the additional teaching status payments 
(if applicable) to the wage, rural, and LIP-adjusted prospective 
payment rates. Table 7 illustrates the components of the adjusted 
payment calculation.

the adjusted payment for Facility B would be $31,387.83.

VII. Update to Payments for High-Cost Outliers Under the IRF PPS for FY 
2026

A. Update to the Outlier Threshold Amount for FY 2026

    Section 1886(j)(4) of the Act provides the Secretary with the 
authority to make payments in addition to the basic IRF prospective 
payments for cases incurring extraordinarily high costs. A case 
qualifies for an outlier payment if the estimated cost of the case 
exceeds the adjusted outlier threshold. We calculate the adjusted 
outlier threshold by adding the IRF PPS payment for the case (that is, 
the CMG payment adjusted by all of the relevant facility-level 
adjustments) and the adjusted threshold amount (also adjusted by all of 
the relevant facility-level adjustments). Then, we calculate the 
estimated cost of a case by multiplying the IRF's overall Cost-to-
Charge Ratio (CCR) by the Medicare allowable covered charge. If the 
estimated cost of the case is higher than the adjusted outlier 
threshold, we make an outlier payment for the case equal to 80 percent 
of the difference between the estimated cost of the case and the 
outlier threshold.
    In the FY 2002 IRF PPS final rule (66 FR 41362 through 41363), we 
discussed our rationale for setting the outlier threshold amount for 
the IRF PPS so that estimated outlier payments would equal 3 percent of 
total estimated payments. For the FY 2002 IRF PPS final rule, we 
analyzed various outlier policies using 3, 4, and 5 percent of the 
total estimated payments, and we concluded that an outlier policy set 
at 3 percent of total estimated payments would optimize the extent to 
which we could reduce the financial risk to IRFs of caring for high- 
cost patients, while still providing for adequate payments for all 
other (non-high cost outlier) cases.
    Subsequently, we updated the IRF outlier threshold amount in the 
FYs 2006 through 2025 IRF PPS final rules and the FY 2011 and FY 2013 
notices (70 FR 47880, 71 FR 48354, 72 FR 44284, 73 FR 46370, 74 FR 
39762, 75 FR 42836, 76 FR 47836, 76 FR 59256, 77 FR 44618, 78 FR 47860, 
79 FR 45872, 80 FR 47036, 81 FR 52056, 82 FR 36238, 83 FR 38514, 84 FR 
39054, 85 FR 48444, 86 FR 42362, 87 FR 47038, 88 FR 50956, and 89 FR 
64276 respectively) to maintain estimated outlier payments at 3 percent 
of total estimated payments. We also stated in the FY 2009 final rule 
(73 FR 46370 through 46385) that we would continue to analyze the 
estimated outlier payments for subsequent years and adjust the outlier 
threshold amount as appropriate to maintain the 3 percent target.
    To update the IRF outlier threshold amount for FY 2026, we proposed 
to use FY 2024 claims data and the same methodology that we used to set 
the initial outlier threshold amount in the FY 2002 IRF PPS final rule 
(66 FR 41362 through 41363), which is also the same methodology that we 
used to update the outlier threshold amounts for FYs 2006 through 2025. 
The outlier threshold is calculated by simulating aggregate payments 
and using an iterative process to determine a threshold that results in 
outlier payments being equal to 3 percent of total payments under the 
simulation. To determine the outlier threshold for FY 2026, we 
estimated the amount of FY 2026 IRF PPS aggregate and outlier payments 
using the most recent claims available (FY 2024) and the proposed FY 
2026 standard payment conversion factor, labor-related share, and wage 
indexes, incorporating any applicable budget-neutrality adjustment 
factors. The outlier threshold is adjusted either up or down in this 
simulation until the estimated outlier payments equal 3 percent of the 
estimated aggregate payments. Based on an analysis of the preliminary 
data used for the proposed rule, we estimated that IRF outlier payments 
as a percentage of total estimated payments would be approximately 2.8 
percent in FY 2025. Therefore, we proposed to update the outlier 
threshold amount from $12,043 for FY 2025 to $11,971 for FY 2026 to 
maintain estimated outlier payments at approximately 3 percent of total 
estimated aggregate IRF payments for FY 2026.
    We note that, with our longstanding practice when developing 
previous IRF PPS fiscal year rules, we update our data between the FY 
2026 IRF PPS proposed and final rules to ensure that we use the most 
recent available data in calculating IRF PPS payments. We are 
finalizing the outlier threshold amount of $10,062 to maintain 
estimated outlier

payments at approximately 3 percent of total estimated aggregate IRF 
payments for FY 2026.
    We invited public comment on the proposed update to the IRF outlier 
threshold for FY 2026.
    The following is a summary of the public comments received on our 
proposed update to the FY 2026 IRF outlier threshold.
    Comment: Commenters were supportive of the update to the outlier 
threshold for FY 2026 and setting outlier payments at 3 percent of 
total payments. Several commenters advised CMS to continue to monitor 
its approach due to the ongoing impacts of the PHE and total cost of 
care. We received one comment urging CMS to consider a 10 percent cap 
on IRF's outlier payments (as a percentage of total IRF PPS revenues) 
due to a concern that a small number of IRF providers are receiving 
large outlier payments despite their case-mix index being similar to 
average IRFs. The commenter believed that factors other than patient 
complexity and case-mix may be driving these payments and presented 
analysis to support their claim that inefficient cost structures, 
rather than highly complex patients, appear to be driving the 
distribution of overall IRF outlier payments, potentially resulting in 
patients at IRFs that warrant an outlier payment not receiving one.
    Response: We continue to believe that maintaining the outlier pool 
at 3 percent of aggregate IRF payments optimizes the extent to which we 
can reduce financial risk to IRFs of caring for highest-cost patients, 
while still providing for adequate payments for non-outlier cases. We 
continue to monitor our approach to assess whether IRFs who treat 
medically complex patients are adequately compensated.
    We acknowledge commenters' concerns that outlier payments may be 
concentrated among a small subset of providers and may not be 
consistently targeted towards patients with intensive or complex needs. 
As most recently discussed in the FY 2025 IRF PPS Final Rule (89 FR 
64276), our outlier policy is intended to reimburse IRFs for treating 
extraordinarily costly cases. We appreciate the commenters' suggestions 
for additional analysis on our methodology and will take them into 
consideration as we continue to assess our outlier threshold.
    Comment: We received multiple comments that recommended that CMS 
implement a new methodology to set the outlier fixed loss amount using 
a 3-year average approach to promote stability in the outlier threshold 
value and to account for the true cost of care for medically complex 
patients. One commenter noted this method would be consistent with 
facility specific adjustments, including teaching, rural, and Low-
Income Percentage (LIP). Multiple commenters also suggested that CMS 
include historical reconciliation dollars in the outlier projection to 
increase accuracy. Moreover, many commenters expressed concern that 
outlier payments are being concentrated among an increasingly small 
number of providers. One commenter suggested that CMS evaluate the 
variation in outlier spending by provider.
    Response: We thank the commenters for their suggestions regarding 
the outlier threshold. We appreciate the suggestion to modify the 
outlier threshold methodology to use a 3-year average; however, it has 
been our long-standing practice to utilize the most recent full fiscal 
year of data to update the prospective payment rates and determine the 
outlier threshold amount as this data is generally considered to be the 
best overall predictor of experience in the upcoming fiscal year. Any 
future consideration given to imposing a limit on outlier payments or 
adjusting the outlier threshold to account for historical outlier 
reconciliation would need to be carefully assessed and take into 
consideration the effect on access to IRF care for certain high-cost 
populations. We continue to believe maintaining the outlier pool at 3 
percent of aggregate IRF payments optimizes the extent to which we can 
reduce financial risk to IRFs of caring for highest-cost patients while 
still providing for adequate payments for other cases. We appreciate 
the commenters' suggestions for refinements to the outlier methodology 
as well as the suggested areas of analysis and will take them into 
consideration as we continue to assess our outlier methodology.
    Comment: Multiple commenters suggested CMS reduce the 3 percent 
outlier pool threshold to a lower percentage which would increase the 
number of complex patients that qualify for the outlier threshold and 
provide appropriate compensation to IRFs.
    Response: We appreciate the suggestion regarding the outlier 
threshold methodology. As most recently discussed in the FY 2025 IRF 
PPS Final Rule (89 FR 64276) our outlier policy is intended to 
reimburse IRFs for treating extraordinarily costly cases. We continue 
to believe that maintaining the outlier pool at 3 percent of aggregate 
IRF payments optimizes the extent to which we can reduce financial risk 
to IRFs of caring for highest-cost patients, while still providing 
adequate payments for all other cases. We will continue to examine ways 
of enhancing the stability and predictability of the outlier threshold 
from year to year. We appreciate the commenters' suggestion for 
refinements to the outlier methodology as well as the suggested areas 
of analysis and will take them into consideration, as we continue to 
assess our outlier threshold policy to ensure it continues to 
compensate IRFs' appropriately.
    Based on our analysis using this updated data, we estimate that IRF 
outlier payments as a percentage of total estimated payments are 
approximately 2.4 percent in FY 2025. Therefore, we will update the 
outlier threshold amount from $12,043 for FY 2025 to $10,062 for FY 
2026 to account for the increases in IRF PPS payments and estimated 
costs to maintain estimated outlier payments at approximately 3 percent 
of total aggregate IRF payments for FY 2026. After consideration of the 
comments received and considering the most recent available data, we 
are finalizing the outlier threshold amount of $10,062 to maintain 
estimated outlier payments at approximately 3 percent of total 
estimated aggregate IRF payments for FY 2026.

B. Update to the IRF Cost-to-Charge Ratio (CCR) Ceiling and Urban/Rural 
Averages for FY 2026

    CCRs are used to adjust charges from Medicare claims to costs and 
are computed annually from facility-specific data obtained from 
Medicare Cost Reports (MCRs). IRF-specific CCRs are used in the 
development of the CMG relative weights and the calculation of outlier 
payments under the IRF PPS. In accordance with the methodology 
described in the FY 2004 IRF PPS final rule (68 FR 45692 through 
45694), we proposed to apply a ceiling to IRFs' CCRs. Using that 
methodology, we proposed to update the national urban and rural CCRs 
for IRFs, as well as the national CCR ceiling for FY 2026, based on 
analysis of the most recent data available. We apply the national urban 
and rural CCRs to:
    <bullet> New IRFs that have not yet submitted their first MCR.
    <bullet> IRFs with an overall CCR that exceeds the national CCR 
ceiling for FY 2026, as discussed below in this section.
    <bullet> Other IRFs for which accurate data to calculate an overall 
CCR are not available.
    Specifically, for FY 2026, we proposed to estimate a national 
average CCR of 0.467 for rural IRFs, which we calculated by taking an 
average of the CCRs for all rural IRFs using their most recently 
submitted cost report data.

[[Page 37700]]

Similarly, we proposed to estimate a national average CCR of 0.398 for 
urban IRFs, which we calculated by taking an average of the CCRs for 
all urban IRFs using their most recently submitted cost report data. We 
applied weights to both of these averages using the IRFs' estimated 
costs, meaning that the CCRs of IRFs with higher total costs factor 
more heavily into the averages than the CCRs of IRFs with lower total 
costs. For this final rule, we used the most recent available cost 
report data (FY 2023). This includes all IRFs whose cost reporting 
periods begin on or after October 1, 2022, and before October 1, 2023. 
If, for any IRF, the FY 2023 cost report was missing or had an ``as 
submitted'' status, we used the most recent FY for which a settled cost 
report was available (that is, from a FY between FY 2004 and FY 2022) 
for that IRF. We do not use cost report data from before FY 2004 for 
any IRF because changes in IRF utilization since FY 2004 resulting from 
the 60 percent rule and IRF medical review activities suggest that 
these older data do not adequately reflect the current cost of care. 
Using updated FY 2023 cost report data for this final rule, we estimate 
a national average CCR of 0.463 for rural IRFs and a national average 
CCR of 0.398 for urban IRFs.
    In accordance with past practice, we proposed to set the national 
CCR ceiling at 3 standard deviations above the mean CCR. Using this 
method, we proposed a national CCR ceiling of 1.54 for FY 2026. This 
means that, if an individual IRF's CCR were to exceed this ceiling of 
1.54 for FY 2026, we will replace the IRF's CCR with the appropriate 
proposed national average CCR (either rural or urban, depending on the 
geographic location of the IRF). We calculated the national CCR ceiling 
by:
    Step 1. Taking the national average CCR (weighted by each IRF's 
total costs, as previously discussed) of all IRFs for which we have 
sufficient cost report data (both rural and urban IRFs combined).
    Step 2. Estimating the standard deviation of the national average 
CCR computed in Step 1.
    Step 3. Multiplying the standard deviation of the national average 
CCR computed in Step 2 by a factor of 3 to compute a statistically 
significant reliable ceiling.
    Step 4. Adding the result from Step 3 to the national average CCR 
of all IRFs for which we have sufficient cost report data, from Step 1.
    We also proposed that if more recent data become available after 
the publication of the proposed rule and before the publication of this 
final rule, we would use such data to determine the FY 2026 national 
average rural and urban CCRs and the national CCR ceiling in the 
proposed rule. Using the FY 2023 cost report data for this proposed 
rule, we estimate a national average CCR ceiling of 1.54, using the 
same methodology.
    We invited public comments on the proposed update to the IRF CCR 
ceiling and the urban/rural averages for FY 2026 and did not receive 
any comments. Consistent with the methodology outlined in the proposed 
rule, and using the most recent cost report data, we are finalizing a 
national average urban CCR at 0.398, the national average rural CCR at 
0.463, and the national average CCR ceiling at 1.54 for FY 2026.

VIII. Inpatient Rehabilitation Facility (IRF) Quality Reporting Program 
(QRP)

A. Background and Statutory Authority

    The Inpatient Rehabilitation Facility Quality Reporting Program 
(IRF QRP) is authorized by section 1886(j)(7) of the Act, and it 
applies to freestanding IRFs, as well as inpatient rehabilitation units 
of hospitals or Critical Access Hospitals (CAHs) paid by Medicare under 
the IRF PPS. Section 1886(j)(7)(A)(i) of the Act requires the Secretary 
to reduce by 2 percentage points the annual increase factor for 
discharges occurring during a FY for any IRF that does not submit data 
in accordance with the IRF QRP requirements set forth in subparagraphs 
(C) and (F) of section 1886(j)(7) of the Act. We have codified our 
program requirements in our regulations at Sec.  412.634.
    In the proposed rule, we proposed to remove two quality measures: 
(1) the COVID-19 Vaccination Coverage among Healthcare Personnel (HCP) 
measure, beginning with the FY 2026 IRF QRP, and (2) the COVID-19 
Vaccine: Percent of Patients/Residents Who Are Up to Date measure, 
beginning with the FY 2028 IRF QRP. We also proposed to remove four 
items previously adopted as standardized patient assessment data 
elements under the social determinants of health (SDOH) category 
beginning with the FY 2028 IRF QRP: one item for Living Situation, two 
items for Food, and one item for Utilities. We also proposed to amend 
our reconsideration policy and process.
    We also sought public comment on several Requests for Information 
(RFIs), specifically on: (1) future measure concepts for the IRF QRP in 
section VII.E of the proposed rule; (2) potential revisions to the IRF-
PAI as described in section VII.F of the proposed rule; (3) potential 
revisions to the data submission deadlines for assessment data 
collected for the IRF QRP as described in section VII.G of the proposed 
rule; (4) advancing digital quality measurement in IRFs as described in 
section VII.H of the proposed rule.

B. General Considerations Used for the Selection of Measures for the 
IRF QRP

    For a detailed discussion of the considerations we use for the 
selection of IRF QRP quality, resource use, or other measures, we refer 
readers to the FY 2016 IRF PPS final rule (80 FR 47083 through 47084).
1. Quality Measures Currently Adopted for the IRF QRP
    The IRF QRP currently has 17 adopted measures, which are listed in 
Table 8.
    For a discussion of the factors, we use to evaluate whether a 
measure should be removed from the IRF QRP, we refer readers to our 
regulations at Sec.  412.634(b)(2). We refer readers to the CY 2013 
OPPS/ASC PPS final rule (77 FR 45194 and 45195) for discussion of our 
policy that allows any quality measure adopted for use in the IRF QRP 
to remain in effect until the measure is removed, suspended, or 
replaced, the FY 2018 IRF PPS final rule (82 FR 36276) which applied 
this policy to standardized patient assessment data we adopt for the 
IRF QRP, and the FY 2019 IRF PPS final rule (83 FR 38556 and 38557) for 
more information on the factors we consider for removing measures and 
standardized patient assessment data.

C. Overview of Quality Measure Proposals

    In the proposed rule, we proposed to remove two measures: (1) the 
COVID-19 Vaccination Coverage among Healthcare Personnel (HCP) measure, 
beginning with the FY 2026 IRF QRP and (2) the COVID-19 Vaccine: 
Percent of Patients/Residents Who Are Up to Date measure, beginning 
with the FY 2028 IRF QRP.
1. Removal of the COVID-19 Vaccination Coverage Among Healthcare 
Personnel (HCP) Measure Beginning With the FY 2026 IRF QRP
    We refer readers to the FY 2022 IRF PPS final rule where we adopted 
the COVID-19 Vaccination Coverage among HCP measure (HCP COVID-19 
measure) into the IRF QRP (86 FR 42385 through 42396) and the FY 2024 
IRF PPS final rule where we modified the HCP COVID-19 measure to 
account for updated vaccine guidance (88 FR 50999 through 51009). To 
report this measure, an IRF must report data on COVID-19 vaccination 
coverage among HCP for at least one week each month. This requires IRFs 
to track current vaccination status for all employees, licensed 
independent practitioners, adult students/trainers and volunteers and 
other contract personnel and log in to the National Healthcare Safety 
Network (NHSN) to report the data monthly either manually in the NHSN 
or by uploading a CSV file (86 FR 42388). The estimated burden of 
collecting this information annually across all 1,166 IRFs is 13,992 
hours at a cost of $503,991.84. We refer readers to section VIII.A.1. 
of this final rule for more details on this estimated burden 
calculation.
    We proposed to remove the HCP COVID-19 measure beginning with the 
FY 2026 IRF QRP under removal Factor 8, the costs associated with a 
measure outweigh the benefit of its continued use in the program (Sec.  
412.634(b)(2)(viii)). When we first adopted the HCP COVID-19 measure, 
the United States was in the midst of a Public Health Emergency (PHE) 
with millions of cases and over 550,000 COVID-19 deaths (86 FR 42385 
and 42386). While preventing the spread of COVID-19 remains a public 
health goal, the PHE ended on May 11, 2023.\7\ In March 2021, when this 
measure was being proposed, the United States was averaging over 5,000 
deaths per week. In April 2023, the last full month of the PHE, weekly 
number of deaths due to COVID-19 averaged around 1,300.\8\ With the end 
of the PHE and the decrease in COVID-19 deaths, we expect the continued 
costs and burden to providers of tracking and monthly reporting on this 
measure to outweigh the benefit of continued information collection on 
COVID-19 vaccination coverage among HCP in IRFs.

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

    If finalized, IRFs that did not report their CY 2024 reporting 
period data for the HCP COVID-19 measure would still be considered 
compliant with the IRF QRP for purposes of their FY 2026 payment 
determination (that is, IRFs that do not report CY 2024 HCP COVID-19 
vaccination data would not be penalized for FY 2026 payments). Any HCP 
COVID-19 Vaccination measure data received by CMS would not be used for 
payment determination.
    We invited public comment on our proposal to remove the COVID-19 
Vaccination Coverage among HCP measure from the IRF QRP beginning with 
the FY 2026 IRF QRP. The following is a summary of the public comments 
received and our responses:
    Comment: Many commenters supported the removal of the COVID-19 
Vaccination Coverage among HCP measure, agreeing that the burden 
required to collect this measure outweighs the benefits. Several 
commenters cited the end of the Public Health Emergency and changes to 
vaccination and booster recommendations in their support. A few 
commenters stated that the availability of vaccines, improved 
treatments, and declining rates of severe

[[Page 37702]]

illness have reduced the need for reporting of HCP vaccination rates.
    A few commenters stated that confusion about the ``up to date'' 
definition led to inaccurate reporting and increased administrative 
tracking and noted that the requirements were not consistent with 
federal and state mandates. These commenters also cited concerns about 
the measure's consideration of medical contraindications and religious 
beliefs. Another commenter stated that the measure has been 
administratively challenging, and that the inclusion of non-employees 
created difficulties for providers.
    Response: We thank these commenters for their support and feedback 
about the measure. We agree that the costs associated with a measure 
outweigh the benefit of its continued use in the program, given the end 
of the PHE.
    Comment: One commenter was opposed to removing the measure, 
recommending that CMS retain one of the COVID-19 vaccine measures to 
ensure public health surveillance for vulnerable populations.
    Response: We appreciate the commenter's concerns for the IRF 
population. However, we note that since the end of the PHE there has 
been an increase in the availability of treatments, including antiviral 
medications used to treat mild to moderate COVID-19 infections in 
vulnerable populations.\9\ Since the number of COVID-19 cases and 
deaths is declining, and the availability of treatments has increased, 
we believe the threat to vulnerable populations, such as IRF patients, 
is also reduced. On these bases, we believe the continued costs and 
burden to providers of reporting this measure outweigh the benefit of 
continued information collection on COVID-19 vaccination coverage among 
HCP in IRFs.

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

    After consideration of the public comments, we are finalizing our 
proposal to remove the COVID-19 Vaccination Coverage among HCP measure 
from the IRF QRP beginning with the FY 2026 IRF QRP.
2. Removal of the COVID-19 Vaccine: Percent of Patients/Residents Who 
Are Up to Date Measure Beginning With the FY 2028 IRF QRP
    We refer readers to the FY 2024 IRF PPS final rule where we adopted 
the COVID-19 Vaccine: Percent of Patients/Residents Who Are Up to Date 
(Patient/Resident COVID-19 Vaccine) measure into the IRF QRP (88 FR 
51026 through 51035). In the FY 2026 IRF PPS proposed rule (90 FR 
18550), we proposed to remove the Patient/Resident COVID-19 Vaccine 
measure beginning with the FY 2028 IRF QRP under removal Factor 8, the 
costs associated with a measure outweigh the benefit of its continued 
use in the program (Sec.  412.634(b)(2)(viii)). The estimated burden of 
collecting this information annually across all 1,166 IRFs is 3,111.5 
hours at a cost of $218,116.15. We refer readers to section IX.A.2. of 
this final rule for more details on this estimated burden reduction.
    When we adopted the Patient/Resident COVID-19 Vaccine measure, 
COVID-19 continued to be a major challenge for IRFs, with older adults 
at a significantly higher risk of mortality, severe disease, and death 
following infection (88 FR 51026).
    IRFs have expressed concerns about data collection challenges and 
increased provider burden in collecting patient immunization data.\10\ 
This is especially true considering the shorter length of stay for IRF 
patients compared to other post-acute settings. While preventing the 
spread of COVID-19 remains a public health goal, the number of COVID-19 
cases and deaths \11\ is declining, and we believe the continued costs 
and burden to providers of reporting this measure outweigh the benefit 
of continued information collection on COVID-19 vaccination coverage 
among patients in IRFs.

    We proposed that, beginning with patients discharged on or after 
October 1, 2025, IRFs would not be required to collect and submit the 
Patient/Resident COVID-19 Vaccine measure data to CMS. We proposed to 
remove the Patient/Resident COVID-19 Vaccine data item (O0350) from the 
IRF-PAI effective October 1, 2026, since it is not technically feasible 
to remove this item earlier. However, under our proposal, this item 
will become voluntary and IRFs would not be required to collect and 
submit Patient/Resident COVID-19 Vaccine data beginning with patients 
discharged on or after October 1, 2025.
    We invited public comment on our proposal to remove the COVID-19 
Vaccine: Percent of Patients/Residents Who Are Up to Date measure from 
the IRF QRP beginning with the FY 2028 IRF QRP.
    The following is a summary of the public comments received on our 
proposed update to remove the COVID-19 Vaccine:
    Comment: We received many comments in support of the proposal to 
remove the Patient/Resident COVID-19 Vaccine measure, agreeing that the 
administrative burden required to collect this measure outweighs the 
benefits. Several commenters noted the end of the Public Health 
Emergency and changes to vaccination and booster recommendations in 
their support for removing the measure. A few commenters noted that IRF 
patients are medically complex and appreciated the flexibility to 
determine how to support infection control among their patients. A few 
commenters stated that COVID-19 vaccination is driven by primary and 
acute care providers and was not appropriate for the IRF setting. One 
commenter asserted that this measure did not have any benefit to the 
public or Medicare program. A few commenters noted the difficulty of 
collecting accurate patient vaccination status. A few commenters 
supported removal, citing issues with the measure response options, 
including the definition of ``up to date'' and the lack of an option to 
indicate patient refusal or exclusion for medical contraindications or 
religious beliefs. These commenters also noted that some IRFs are not 
able to provide the vaccine to patients and also noted that vaccine 
side effects may impede patients from participating in therapy.
    Response: We thank commenters for their support. We acknowledge 
commenters' difficulty with assessing patient's vaccination status in 
the IRF, given that the IRF length of stay is shorter compared to other 
post-acute care settings. We agree that the costs associated with this 
measure, including the resources spent by IRF staff in trying to 
ascertain patients' vaccination status, outweigh the benefit of its 
continued use in the program, given the end of the PHE, the decrease in 
COVID cases as well as the availability of treatments.
    Comment: We received a few comments that were supportive of the 
measure removal, but requested an earlier timeframe, citing data 
collection burden. These commenters requested that CMS not penalize 
IRFs for failing to report data for the Patient/Resident COVID-19 
Vaccine measure for CY 2024 and January through September 2025. Another 
commenter requested that the Patient/Resident Vaccine item be removed 
from the IRF-PAI on October

[[Page 37703]]

1, 2025, to avoid confusion and workflow delays.
    Response: IRFs have been required to report this measure on the 
IRF-PAI since October 1, 2024. According to internal CMS analysis of 
IRF-PAI data, IRFs have a data submission rate of approximately 99 
percent with regard to the required IRF QRP data elements on the IRF 
PAI. We do not anticipate a substantial number of IRFs to be non-
compliant with FY 2026 IRF QRP due to non-submission of this measure 
for CY 2024 quarter 4. We are consistently monitoring these data as 
they are submitted for trends that may indicate barriers to data 
submission and will continue to do so as we conclude the FY 2026 IRF 
QRP program year.
    Regarding the suggestion to remove the item from the IRF-PAI on 
October 1, 2025, it is not operationally feasible to remove this 
measure from the IRF-PAI, since CMS, IRFs and vendors need more time to 
prepare for an update to the item set and data specifications. Instead, 
we proposed, and are finalizing, that reporting the data on this 
measure using the IRF-PAI will be optional beginning October 1, 2025. 
Because data collected in Q4 of 2025 (October 1, 2025-December 31, 
2025) are used in determining the minimum data completion threshold for 
the FY 2027 IRF QRP determination, we intend to provide updates to the 
website to indicate that the Patient/Resident COVID-19 Vaccine data 
item (O0350) is optional for the final quarter of the data collection 
period for the FY 2027 Annual Increase Factor Determination (that is, 
Q4 of 2025) and we will not penalize IRFs who select not complete this 
item during Q4 of 2025. The item will be optional until it can be 
removed from the IRF-PAI with the next iteration of the IRF-PAI 
scheduled for release October 1, 2026.
    Comment: One commenter was opposed to removing the measure, 
recommending that CMS retain one of the COVID-19 vaccine measures to 
ensure public health surveillance for vulnerable populations.
    Response: We appreciate the commenter's concerns for the IRF 
population. However, we wish to clarify that this measure did not 
provide surveillance data about COVID-19 cases among IRF patients; 
rather it assessed whether patients in submitting IRFs were up to date 
in their COVID-19 vaccinations. Removing this measure will not impact 
the public health surveillance of COVID-19. We also note that since the 
end of the PHE, there has been an increase in the availability of 
treatments, including antiviral medications used to treat mild to 
moderate COVID-19 in vulnerable populations.\12\ As we stated in the 
proposed rule, because the number of COVID-19 cases and deaths is 
declining and the availability of treatments has increased, we believe 
the threat to vulnerable populations, such as IRF patients, is also 
reduced. On these bases, we believe the continued costs and burden to 
providers of reporting this measure outweigh the benefit of continued 
information collection on COVID-19 vaccination coverage among patients 
in IRFs.

    After consideration of the public comments, we are finalizing our 
proposal to remove the COVID-19 Vaccine: Percent of Patients/Residents 
Who Are Up to Date measure from the IRF QRP beginning with the FY 2028 
IRF QRP. Beginning with patients discharged on or after October 1, 
2025, IRFs would not be required to collect and submit the Patient/
Resident COVID-19 Vaccine measure data to CMS, and IRFs who do not 
report this data for Q4 of 2025 will not be penalized for the FY 2027 
Annual Increase Factor Determination.

D. Removal of Four Standardized Patient Assessment Data Elements 
Beginning With the FY 2028 IRF QRP

    We refer readers to the FY 2025 IRF PPS final rule (89 FR 64310 
through 64322) where we finalized the adoption of four items as 
standardized patient assessment data elements under the SDOH category 
from the IRF-PAI: one item for Living Situation (R0310); two items for 
Food (R0320A and R0320B); and one item for Utilities (R0330). As 
finalized in the FY 2025 IRF PPS final rule, IRFs would be required to 
report these data elements using the IRF-PAI beginning with patients 
discharged on or after October 1, 2026 through December 31, 2026 for 
purposes of the FY 2028 IRF QRP and each program year after (89 FR 
64326 through 64327).
    In the proposed rule, we proposed to remove these four standardized 
patient assessment data elements under the SDOH category from the IRF-
PAI as we acknowledge the burden associated with these items at this 
time. We continuously look for ways to balance the need for data 
collections regarding quality care and the burden that such data 
collections may have on healthcare providers. One goal we have is to 
facilitate improved healthcare delivery by requiring different systems 
and software applications to communicate and exchange data. Therefore, 
we would like to work towards the workflow for these specific data 
elements being part of a low burden interoperable electronic system. 
The focus will turn towards how these data and associated 
recommendations can improve care coordination, efficiency, reduction in 
errors and patient experience. As health information technology (IT) 
advances and interoperability of data becomes more standardized, the 
burden to collect and share clinical data on these and other relevant 
patient information will become less burdensome, allowing for better 
outcomes for IRF patients and their families. The objectives of the IRF 
QRP continue to be the improvement of care, quality and health outcomes 
for all patients through transparency and quality measurement, while 
not imposing undue burden on essential health providers. We proposed 
that IRFs would not be required to collect and submit Living Situation 
(R0310), Food (R0320A and R0320B), and Utilities (R0330) items using 
the IRF-PAI beginning with the patients discharged on or after October 
1, 2026, removing the required collection and reporting of these items 
that we previously finalized. We also proposed that collecting these 
items would not be required to meet the IRF QRP requirements to avoid a 
2 percent payment reduction beginning with the FY 2028 IRF QRP.
    In the proposed rule, we calculated that removing these items from 
the data collection for the FY 2028 IRF QRP would keep the 1,166 IRFs 
from incurring 12,446 hours of administrative burden at a cost of 
$872,464.60 (or $748.25 per IRF) at this time (90 FR 18557 and 18558). 
We refer readers to section IX.A.3. of this final rule for more details 
on this estimated burden reduction.
    We invited public comments on our proposal to remove four 
standardized patient assessment data elements collected under the SDOH 
category from the IRF QRP beginning with the FY 2028 IRF QRP.
    The following is a summary of the public comments received on our 
proposal to remove these four standardized patient assessment data 
elements.
    Comment: Many commenters supported the proposed removal of the four 
SDOH assessment data elements, citing that these added complexity and 
administrative burden to the patient assessment process. A few 
commenters expressed concerns about how these data elements can be 
time-consuming to collect and detract from direct patient care. Several 
commenters acknowledged that CMS must work towards a balance of 
provider burden and data collection efforts for quality, ensuring data 
adds

[[Page 37704]]

value to its program and advances health care.
    Many commenters in support of removing the four SDOH data elements 
noted that these SDOH data are important to patient outcomes and 
continue to be a priority among IRFs. They stated, however, this 
information is already part of the best practices for discharge 
planning, used for uncovering barriers to a safe transition and 
preventing readmissions. Several of these commenters believed that most 
IRFs already collect these elements and signaled they will continue to 
do so as they find it beneficial to their patient population, if they 
need it to meet accreditation standards, such as The Joint Commission, 
and for internal quality improvement efforts and population health 
initiatives. By removing the four SDOH data elements from the IRF QRP, 
this commenter asserted that we are preserving flexibility in IRFs 
addressing risk factors in ways that are more clinically relevant.
    Response: We thank commenters for their support. We continue to 
monitor the IRF QRP data collection requirements to look for ways to 
reduce the administrative burden where appropriate while maintaining a 
high standard of quality care. We agree that removing these particular 
items at this time will alleviate some of the burden on providers 
associated with IRF QRP data collection and submission. We intend to 
align the IRF QRP more closely with CMS's overarching goal for improved 
healthcare delivery through health IT advances and less burdensome 
interoperable electronic systems. As we stated in the proposed rule (90 
FR 18534), we plan to refocus efforts on how data elements can improve 
care coordination, efficiency, reduction in errors, and patient 
experience.
    Additionally, we acknowledge that many IRF providers have already 
been tracking SDOH. We agree that collecting this information is 
beneficial for IRFs regardless of the requirements of the IRF QRP, as 
it facilitates discharge planning and contributes to quality 
improvement as well as accreditation efforts.
    Comment: A few commenters support removal of the four SDOH data 
elements from the IRF-PAI because they are not currently used in any 
quality measures or risk adjustment models, or being utilized by CMS in 
an actionable way, and their collection is therefore an unnecessary 
burden on IRFs participating in the QRP. A few other commenters stated 
there was no clear evidence that collecting these items has led to 
measurable improvements in care transitions or outcomes in the IRF 
setting.
    Response: Regarding the comments stating that the data elements 
have not been utilized by CMS in an actionable way, we wish to clarify 
that IRFs have not begun any data collection on the SDOH data elements 
for the IRF QRP. While we finalized the adoption of the four SDOH data 
elements in the FY 2025 IRF PPS final rule, IRFs would have been 
required to report these data elements using the IRF-PAI beginning with 
patients discharged on or after October 1, 2026 (89 FR 64326 through 
64327).
    Regarding comments about evidence for measurable improvements in 
case transitions or outcomes in the IRF setting, while we are not aware 
of evidence in the IRF setting at this time, we will continue to 
monitor this topic as we consider future data elements in the IRF QRP. 
In response to the comments about the SDOH data elements not being used 
in quality measures or for risk adjustment, we note that the IRF QRP 
requires data collections that are not strictly limited to quality 
measures or risk adjustment. Section 1886(j)(7)(F)(ii) of the Act 
requires IRFs to submit standardized patient assessment data required 
under section 1899B(b)(1) of the Act.
    Comment: Many commenters were opposed to CMS's proposal to remove 
the four SDOH data elements from the IRF-PAI and urged CMS to 
reconsider the proposal. These commenters believe that this data adds 
value to IRFs, citing existing literature on how SDOH improves health 
outcomes and how this information facilitates discharge planning by 
providing a proactive approach to risks and earlier intervention. The 
commenters felt that clinical care provided by the IRF can be 
undermined when basic needs are not met. A few commenters noted that 
these items can help reduce healthcare costs by allowing IRFs to 
address these factors as part of a comprehensive and preventative 
approach to care. Other commenters stated the SDOH data elements were 
particularly important in caring for patients with complex or chronic 
conditions and geriatric patients, and that the data can help reduce 
hospital readmissions, emergency department visits and hospitalizations 
when paired with interventions and community support services. Two 
commenters further stated that understanding SDOH factors can 
illuminate drivers behind poor patient outcomes and supports efforts 
towards finding evidence-based, measurable solutions to differences in 
health care among certain populations.
    Response: We appreciate commenters' concerns and feedback regarding 
the importance of collecting these SDOH data elements from IRF patients 
to capture and address unmet needs and particularly highlighting their 
importance for complex patient populations such as those with chronic 
conditions and geriatric patients. We acknowledge commenters' 
experiences using SDOH data to monitor and improve health care outcomes 
may be different for those experiencing unstable housing, food 
insecurity or challenges paying utilities, and recognize feedback from 
some commenters stating that they currently collect and will continue 
to collect this information.
    However, in reviewing the data collection and reporting 
requirements for the FY 2028 IRF QRP, we determined that these SDOH 
items should be removed from the IRF-PAI prior to the start of data 
collection and submission. We have re-evaluated the value of adding 
these SDOH items for the purposes of the IRF QRP against their burden 
at this time. Collecting these SDOH items is not a one-time task but an 
ongoing requirement for every IRF patient admitted to the facility if 
the items became part of the IRF QRP.
    We considered that IRFs have not yet begun to report these data, 
that we do not currently use these items in the IRF QRP for measures or 
risk adjustment, and that these SDOH items are not clinical items 
related to direct patient care while a patient is admitted to an IRF. 
We also have refocused our efforts on modernization of health care and 
health care systems which may support a less burdensome way of 
collecting SDOH items in the future. We continuously review and 
reassess the balance of data collection and IRF provider burden for the 
IRF QRP, and at this time determined these SDOH items should be removed 
prior to implementation.
    The objectives of the IRF QRP continue to be the improvement of 
care, quality and health outcomes for all patients through transparency 
and quality measurement, while balancing burden for IRF providers. As 
outlined in our request for information in the FY 2026 IRF PPS proposed 
rule (90 FR 18554), we are refocusing our efforts to include ways for 
data elements, such as those related to SDOH, being part of a less 
burdensome, more streamlined, and interoperable electronic system. 
Given these administrative goals and efforts to reduce burden for IRFs, 
we do not believe that the value of collecting SDOH data elements via 
the IRF-PAI outweighs the cost and burden of collecting them at this 
time.
