I. Executive Summary

A. Purpose

    This major final rule revises payment policies under the Medicare 
PFS and makes other policy changes, including to the implementation of 
certain provisions of the Full-Year Continuing Appropriations and 
Extensions Act, 2025 (Pub. L. 119-4, March 15, 2025), Further 
Continuing Appropriations and Other Extensions Act of 2024 (Pub. L. 
118-22, November 17, 2023), Consolidated Appropriations Act, 2023 (Pub. 
L. 117-328, December 29, 2022), Inflation Reduction Act of 2022 (IRA) 
(Pub. L. 117-169, August 16, 2022), Consolidated Appropriations Act, 
2022 (Pub. L. 117-103, March 15, 2022), Consolidated Appropriations 
Act, 2021 (CAA, 2021) (Pub. L. 116-260, December 27, 2020), Bipartisan 
Budget Act of 2018 (BBA of 2018) (Pub. L. 115-123, February 9, 2018), 
the Substance Use-Disorder Prevention that Promotes Opioid Recovery and 
Treatment for Patients and Communities Act (SUPPORT Act) (Pub. L. 115-
271, October 24, 2018) and Consolidated Appropriations Act, 2026 (Pub. 
L. 119-75, February 3, 2026), related to Medicare Part B payment. In 
addition, this final rule includes other Medicare payment and 
eligibility provisions described in sections III. and IV.
    This final rule updates policies for the Medicare Prescription Drug 
Inflation Rebate Program codified at 42 CFR parts 427 and 428 
consistent with sections 1847A(i) and 1860D--14B of the Social Security 
Act (the Act). For the Medicare Part B Drug Inflation Rebate Program, 
this rule describes the identification of the Consumer Price Index for 
all Urban Consumers (CPI-U) for the payment amount benchmark quarter 
and the rebate period in certain instances when CPI-U survey data are 
unavailable and the calculation of the Part B rebate amount in such 
instances; clarifies the definition of ``first marketed date''; and 
clarifies that certain skin substitutes would not be excluded from the 
definition of a Part B rebatable drug. For the Medicare Part D Drug 
Inflation Rebate Program, this rule describes the identification of the 
CPI-U for the payment amount benchmark period and applicable period in 
certain instances when CPI-U survey data are unavailable and the 
calculation of the Part D rebate amount in such instances; modifies the 
methodology finalized in the CY 2026 PFS final rule to account for 
340B-eligible units for AIDS Drug Assistance Program (ADAP) clients for 
the applicable period beginning October 1, 2025; and requires Medicare 
providers and suppliers that are 340B covered entities to submit Part D 
340B claims data to the Medicare Part D Claims Data 340B Repository 
beginning in 2027.
    This final rule modifies policies for the Shared Savings Program, 
which is a voluntary program that started in 2012. The program allows 
groups of providers and suppliers to form or participate in Accountable 
Care Organizations (ACOs), and to be held accountable for the quality 
and total cost of care for an assigned population of Medicare fee-for-
service (FFS) beneficiaries.

B. Summary of the Key Provisions

    Section 1848 of the Act requires us to establish payments under the 
PFS, based on national uniform relative value units (RVUs) that account 
for the relative resources used in furnishing a service. The statute 
requires that RVUs be established for three categories of resources: 
work, practice expense (PE), and malpractice (MP) expense. In addition, 
the statute requires that each year we establish, by regulation, the 
payment amounts for physicians' services paid under the PFS, including 
geographic adjustments to reflect the variations in the costs of 
furnishing services in different geographic areas.
    In this major final rule, we are finalizing RVUs for CY 2027 for 
the PFS to ensure that our payment systems are updated to reflect 
changes in medical practice and the relative value of services, as well 
as changes in the statute. This final rule also includes discussions 
and provisions regarding several other Medicare Part B payment 
policies, and other policies regarding programs administered by CMS.
    Specifically, this final rule addresses:

<bullet> Determination of PE RVUs (section II.B.)
<bullet> Payment for Medicare Telehealth Services (section II.C.)
<bullet> Valuation of Specific Codes, Including Potentially Misvalued

<bullet> Regulatory Impact Analysis (section VI.)

C. Summary of Costs and Benefits

    Based on our estimates, the Office of Information and Regulatory 
Affairs in the Office of Management and Budget has determined that this 
final rule is economically significant under section 3(f)(1) of 
Executive Order 12866. As required by section 1848(d)(1)(A) of the Act, 
beginning in 2026, there are two separate conversion factors (CFs): one 
for items and services furnished by a qualifying APM participant (QP) 
as defined in section 1833(z)(2) of the Act and 42 CFR 414.1305 
(referred to as the qualifying APM conversion factor) and another for 
items and services furnished by clinicians who are not QPs (referred to 
as the nonqualifying APM conversion factor), equal to the respective 
conversion factor for the previous year multiplied by the update 
established under section 1848(d)(20) of the Act for such respective 
conversion factor for such year. Under these provisions, the 2027 
qualifying APM conversion factor represents a projected decrease of 
$0.62 (-1.83 percent) from the current conversion factor of $33.5675. 
Similarly, the 2027 nonqualifying APM conversion factor represents a 
projected decrease of $0.77 (-2.31 percent) from the current conversion 
factor of $33.4009.

Regulatory Impact Analysis, of this final rule.

D. Public Comments in Response on the CY 2027 PFS Proposed Rule

    We received approximately 43,100 timely pieces of correspondence on 
the CY 2027 PFS proposed rule that appeared in the Federal Register on 
July 14, 2026 (91 FR 43842 through 44557). We received comments from 
individuals, providers and suppliers, practitioners, and advocacy 
groups. We provide summaries of the public comments, and our responses 
are set forth in the various sections of this final rule under the 
appropriate headings. We note that we received some public comments 
that were outside the scope of the CY 2027 PFS proposed rule.

II. Provisions of the Rule for the PFS

A. Background

    In accordance with section 1848 of the Social Security Act (the 
Act), CMS has paid for physicians' services under the Medicare 
physician fee schedule (PFS) since January 1, 1992. The PFS relies on 
national relative values that are established for work, practice 
expense (PE), and malpractice (MP), which are adjusted for geographic 
cost variations. These values are multiplied by a conversion factor 
(CF) to convert the relative value units (RVUs) into payment rates. The 
concepts and methodology underlying the PFS were enacted as part of the 
Omnibus Budget Reconciliation Act of 1989 (OBRA '89) (Pub. L. 101-239, 
December 19, 1989), and the Omnibus Budget Reconciliation Act of 1990 
(OBRA '90) (Pub. L. 101-508, November 5, 1990). The final rule 
published in the November 25, 1991 Federal Register (56 FR 59502) set 
forth the first fee schedule used for Medicare payment for physicians' 
services.
    We note that throughout this final rule, unless otherwise noted, 
the term ``practitioner'' is used to describe both physicians and 
nonphysician practitioners (NPPs) who are permitted to bill Medicare 
under the PFS for the services they furnish to Medicare beneficiaries.

B. Determination of PE RVUs

1. Overview
    Practice expense (PE) is the portion of the resources used in 
furnishing a service that reflects the general categories of physician 
and practitioner expenses, such as office rent and personnel wages, but 
excluding malpractice (MP) expenses, as specified in section 
1848(c)(1)(B) of the Act. As required by section 1848(c)(2)(C)(ii) of 
the Act, we use a resource-based system for determining PE RVUs for 
each physicians' service. We develop PE RVUs by considering the direct 
and indirect practice resources involved in furnishing each service. 
Direct expense categories include clinical labor, medical supplies, and 
medical equipment. Indirect expenses include administrative labor, 
office expenses, and all other expenses. The sections that follow 
provide more detailed information about the methodology for translating 
the resources involved in furnishing each service into service specific 
PE RVUs. We refer readers to the CY 2010 Physician Fee Schedule (PFS) 
final rule with comment period (74 FR 61743 through 61748) for a more 
detailed explanation of the PE methodology.
2. Practice Expense Methodology
a. Direct Practice Expense
    We determine the direct PE for a specific service by adding the 
costs of the direct resources (that is, the clinical staff, medical 
supplies, and medical equipment) typically involved with furnishing 
that service. The costs of the resources are calculated using the 
refined direct PE inputs assigned to each CPT code in our PE database, 
which are generally based on our review of recommendations received 
from the American Medical Association (AMA)/Specialty Society Relative 
Value Scale (RVS) Update Committee (referred to as the RUC) and those 
provided in response to public comment periods. For a detailed 
explanation of the direct PE methodology, including examples, we refer 
readers to the 5-year review of work RVUs under the PFS and changes to 
the PE methodology in the CY 2007 PFS proposed rule (71 FR 37242) and 
the CY 2007 PFS final rule with comment period (71 FR 69629).
b. Indirect Practice Expense per Hour Data
    We use survey data on indirect PEs incurred per hour (PE/HR) worked 
to develop the indirect portion of the PE RVUs. Prior to CY 2010, we 
primarily used the PE/HR by specialty obtained from the AMA's 
Socioeconomic Monitoring System (SMS). The AMA administered a new 
survey in CY 2007 and CY 2008, the Physician Practice Information 
Survey (PPIS). The PPIS is a multispecialty, nationally representative, 
PE survey of physicians and NPPs paid under the PFS using a survey 
instrument and methods highly consistent with those used for the SMS 
and the supplemental surveys. The PPIS gathered information from 3,656 
respondents across 51 physician specialty and health care professional 
groups. We have stated that we believe the PPIS is the most 
comprehensive source of PE survey information available. We used the 
PPIS data to update the PE/HR data for the CY 2010 PFS for almost all 
of the Medicare-recognized specialties that participated in the survey.
    When we began using the PPIS data in CY 2010, we did not change the 
PE RVU methodology or how the PE/HR data are used. We only updated the 
PE/HR data based on the new survey. Furthermore, as we explained in the 
CY 2010 PFS final rule with comment period (74 FR 61751), because of 
the magnitude of payment reductions for some specialties resulting from 
the use of the PPIS data, we transitioned its use over a 4-year period 
from the previous PE RVUs to the PE RVUs developed using the new PPIS 
data. As provided in the CY 2010 PFS final rule with comment period (74 
FR 61751), the transition to the PPIS data was complete for CY 2013. 
Therefore, PE RVUs from CY 2013 forward are developed based entirely on 
the PPIS data, except as noted in this section.
    Section 1848(c)(2)(H)(i) of the Act requires us to use the medical 
oncology supplemental survey data submitted in 2003 for oncology drug 
administration services. Therefore, the PE/HR for medical oncology, 
hematology, and hematology/oncology reflects the continued use of these 
supplemental survey data.
    Supplemental survey data on independent labs from the College of 
American Pathologists were implemented for payments beginning in CY 
2005. Supplemental survey data from the National Coalition of Quality 
Diagnostic Imaging Services (NCQDIS), representing independent 
diagnostic testing facilities (IDTFs), were blended with supplementary 
survey data from the American College of Radiology (ACR) and 
implemented for payments beginning in CY 2007. Neither IDTFs nor 
independent labs participated in the PPIS. Therefore, we continue to 
use the PE/HR that was developed from their supplemental survey data.
    Consistent with our past practice, the previous indirect PE/HR 
values from the supplemental surveys for these specialties were updated 
to CY 2006 using the Medicare Economic Index (MEI) to put them on a 
comparable basis with the PPIS data.
    We also do not use the PPIS data for reproductive endocrinology and 
spine surgery since these specialties are not separately recognized by 
Medicare, nor

[[Page 70995]]

do we have a method to blend the PPIS data with Medicare-recognized 
specialty data.
    Previously, we established PE/HR values for various specialties 
without SMS or supplemental survey data by crosswalking them to other 
similar specialties to estimate a proxy PE/HR. For specialties that 
were part of the PPIS for which we previously used a crosswalked PE/HR, 
we instead used the PPIS based PE/HR. We use crosswalks for specialties 
that did not participate in the PPIS. These crosswalks have been 
generally established through notice and comment rulemaking and are 
available in the file titled ``CY 2027 PFS Final Rule PE/HR'' on the 
CMS website under downloads for the CY 2027 PFS final rule at <a href="https://www.cms.gov/medicare/payment/fee-schedules/physician/federal-regulation-notices">https://www.cms.gov/medicare/payment/fee-schedules/physician/federal-regulation-notices</a>.
c. Allocation of PE to Services
    To establish PE RVUs for specific services, it is necessary to 
establish the direct and indirect PE associated with each service.
(1) Direct Costs
    The relative relationship between the direct cost portions of the 
PE RVUs for any two services is determined by the relative relationship 
between the sum of the direct cost resources (that is, the clinical 
staff, medical supplies, and medical equipment) typically involved with 
furnishing each of the services. The costs of these resources are 
calculated from the refined direct PE inputs in our PE database. For 
example, if one service has a direct cost sum of $400 from our PE 
database and another service has a direct cost sum of $200, the direct 
portion of the PE RVUs of the first service would be twice as much as 
the direct portion of the PE RVUs for the second service.
(2) Indirect Costs
    Under current policy, we allocate the indirect costs at the code 
level based on the direct costs specifically associated with a code and 
the greater of either the clinical labor costs or the work RVUs. We 
also incorporate the survey data described earlier in the PE/HR 
discussion. The general approach to developing the indirect portion of 
the PE RVUs is as follows:
    <bullet> For a given service, we use the direct portion of the PE 
RVUs calculated as previously described and the average percentage that 
direct costs represent of total costs (based on survey data) across the 
specialties that furnish the service to determine an initial indirect 
allocator. That is, the initial indirect allocator is calculated so 
that the direct costs equal the average percentage of direct costs of 
those specialties furnishing the service. For example, if the direct 
portion of the PE RVUs for a given service is 2.00 and direct costs, on 
average, represent 25 percent of total costs for the specialties that 
furnish the service, the initial indirect allocator would be calculated 
so that it equals 75 percent of the total PE RVUs. Thus, in this 
example, the initial indirect allocator would equal 6.00, resulting in 
a total PE RVU of 8.00 (2.00 is 25 percent of 8.00 and 6.00 is 75 
percent of 8.00).
    <bullet> Next, under current policy, we add the greater of the work 
RVUs or clinical labor portion of the direct portion of the PE RVUs to 
this initial indirect allocator. In our example, if this service had a 
work RVU of 4.00 and the clinical labor portion of the direct PE RVU 
was 1.50, we would add 4.00 (since the 4.00 work RVUs are greater than 
the 1.50 clinical labor portion) to the initial indirect allocator of 
6.00 to get an indirect allocator of 10.00. In the absence of any 
further use of the survey data, the relative relationship between the 
indirect cost portions of the PE RVUs for any two services would be 
determined by the relative relationship between these indirect cost 
allocators. For example, if one service had an indirect cost allocator 
of 10.00 and another service had an indirect cost allocator of 5.00, 
the indirect portion of the PE RVUs of the first service would be twice 
as great as the indirect portion of the PE RVUs for the second service.
    <bullet> Then, we incorporate the specialty specific indirect PE/HR 
data into the calculation. In our example, if, based on the survey 
data, the average indirect cost of the specialties furnishing the first 
service with an allocator of 10.00 was half of the average indirect 
cost of the specialties furnishing the second service with an indirect 
allocator of 5.00, the indirect portion of the PE RVUs of the first 
service would be equal to that of the second service.
    In the CY 2007 PFS final rule with comment period, we implemented 
the ``bottom up'' methodology for the development of PE RVUs (71 FR 
69630-69643). We finalized the use of the work RVU or the clinical 
labor portion of the direct PE RVU, whichever is greater, to allocate 
indirect costs. We also finalized a modified formula for a global 
service (that is, a service with a professional component (PC) and a 
technical component (TC)) to utilize both the work RVU and the clinical 
labor PE RVU to allocate indirect costs. As noted in the CY 2007 PFS 
final rule with comment period, we do this to recognize that, for the 
PC service, indirect PEs will be allocated using the work RVUs, and for 
the TC service, indirect PEs will be allocated using the direct PE RVU 
and the clinical labor PE RVU. This also allows the global component 
RVUs to equal the sum of the PC and TC RVUs.
    In recent years, as we have conducted analyses aimed at improving 
the accuracy of payment under the PFS, we have re-examined this 
longstanding policy that effectively allocates a larger share of 
indirect PE RVUs to services that can be reported using technical, 
professional, and global components than to those that cannot. We refer 
the reader to a report by RAND Corporation, under contract with CMS, 
which addresses several approaches to improving the accuracy of other 
PFS services relative to services that have a professional and 
technical component. This report is available at <a href="https://www.rand.org/pubs/research_reports/RRA4720-2.html">https://www.rand.org/pubs/research_reports/RRA4720-2.html</a>.
    This longstanding policy inadvertently advantages services that can 
be reported using technical, professional, and global components, 
referred to as ``triplet services'' in the report by RAND Corporation, 
because indirect PE RVUs are allocated on the sum, whereas services 
that can only be reported as a global service, referred to as ``non-
triplet services'' in the report, depend on the maximum (rather than 
sum) of clinical labor PE RVUs and physician work RVUs. This is an 
unintended advantage of the arithmetic required for the global 
component RVUs to equal the sum of the PC and TC RVUs. As we stated in 
the proposed rule, we believe it would be more accurate than the 
current PE methodology to use the same allocation methodology for all 
PFS services. Therefore, we proposed to allocate indirect PE using both 
the work RVU and the clinical labor RVU for all services, with the 
exception of codes with 10- and 90-day global periods, instead of just 
applying that methodology to those services that can be reported using 
technical, professional, and global components (typically diagnostic 
and imaging services). In the description of the calculation of the PE 
methodology noted later in the section, we indicate the portion of the 
methodology that would be calculated differently under this proposal.
    We received public comments on this proposal. The following is a 
summary of the comments we received and our responses.
    Comment: Several commenters stated that CMS did not provide a 
rationale for excluding 10- and 90-day global codes from the proposed 
revised indirect PE

[[Page 70996]]

allocation in the proposed rule. Some commenters stated that the RAND 
analysis published alongside the proposed rule did not exclude these 
global codes, disagreed with CMS' exclusion of 10- and 90-day global 
codes and requested that we finalize their inclusion in the proposal to 
allocate indirect PE using both the work RVU and the clinical labor RVU 
for all services. Some commenters supported the exclusion of the 10- 
and 90-day global period codes from the proposal. They reiterated our 
ongoing questions and concerns about the current valuation of work and 
clinical labor RVUs for 10- and 90-day global period codes noted 
elsewhere in section II.B. of this final rule, and said that the 
proposed change should not be extended to those codes until the other 
questions and concerns are addressed. Another commenter requested that 
the exclusion of the 10- and 90-day global period codes does not 
further delay the separate work needed to correct documented 
misvaluation within global surgical payments.
    Response: We appreciate the commenters' feedback and note that we 
inadvertently omitted a specific rationale for their exclusion in the 
proposed rule. We discussed difficulties and concerns with the global 
period codes elsewhere in section II.B. of the proposed rule (91 FR 
43861) and similarly excluded 10- and 90-day global surgery services 
from the new ``CY 2027 PFS Proposed Rule Display Only TC PE RVUs'' 
public use file discussed in the proposed rule. Specifically, the use 
of bundled payments for the 10- and 90-day global surgery services 
results in aggregated valuation for all pre-operative, intra-operative, 
and post-operative services furnished over a defined period (10-, or 
90-day global periods), including services by both physician and 
clinical staff and practice expense without clear visibility into how 
each component contributes to the total bundled valuation. This is the 
rationale referenced previously that was inadvertently omitted from the 
proposed rule.
    This unintended advantage of the arithmetic required for the global 
component RVUs to equal the sum of the PC and TC RVUs has led to 
concerns of incorrect relativities between PFS services. While the RAND 
report recommends allocating indirect PE using the sum of work and 
clinical labor as a default for all services (that is, not just those 
with TC/PC splits), the report also notes that strategies CMS might 
pursue to mitigate these concerns could interact with other aspects of 
Medicare payment policy, leading to unintentional or undesired effects 
or the need for special adjustments or other consideration for certain 
PFS services.
    Additionally, other RAND reports <SUP>1 2 3 4</SUP> and recent OIG 
reports <SUP>5 6</SUP> have consistently found that substantially fewer 
post-operative visits are typically provided to Medicare beneficiaries 
as part of 10- and 90-day global periods compared to the number of 
assumed post-operative visits considered in surgical procedure 
valuation. Including the 10- and 90-day global surgery services in the 
proposed revised indirect PE allocation would have significantly 
increased the indirect PE allocated to these services and amplified the 
payment distortions that result from including too many post-operative 
visits in global packages because there is work and clinical labor 
bundled into the valuation associated with the post-operative visits. 
Similar to how we do not believe codes with technical, professional, 
and global components should be advantaged over other services by the 
indirect PE allocation using both the work RVU and clinical labor RVU, 
we do not believe global period services should be advantaged by the 
proposal because they have additional work & clinical labor RVUs 
bundled into their post-operative periods.

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

    Comment: A commenter expressed concern with the proposal, stating 
that the proposal was aimed at addressing the assertion in RAND's 
report that the current indirect PE methodology may contribute to 
overutilization of imaging services. The commenter stated that, absent 
evidence demonstrating that indirect PE allocation directly affects 
ordering behavior or utilization patterns, they believe we should 
proceed cautiously before implementing significant redistributions of 
RVUs based on assumptions regarding imaging utilization.
    Response: We appreciate the commenter's feedback. We note that, as 
discussed in the proposed rule, this longstanding policy inadvertently 
advantages services that can be reported using technical, professional, 
and global components, and is an unintended advantage of the arithmetic 
required for the global component RVUs to equal the sum of the PC and 
TC RVUs. We note that we did not propose this change to address any 
utilization patterns discussed in RAND's report, but rather, to address 
the longstanding and unintended advantage because we believe it would 
be more accurate than the current PE methodology to use the same 
allocation methodology for all PFS services.
    Comment: A commenter stated they could not determine whether CMS 
incorporated this proposed modification into the calculation of PE RVUs 
for the proposed rule. They stated that, in the separately published 
Sample Calculation of PE RVUs under Methodology for Selected Codes 
public use file, CMS indicated that the second component of the 
indirect PE allocator for CPT code 99213 is based on the work RVU and 
does not appear to incorporate the clinical labor as proposed.
    Response: We appreciate the commenter's feedback and acknowledge 
the concern. Because this was a proposed change, our methodology public 
use files, such as the Sample Calculation of PE RVUs under Methodology 
for Selected Codes and CY 2027 PFS Proposed Rule Practice Expense 
Algorithm Technical Memo, displayed information regarding the 
methodology in its current state for the proposed rule, so as to not 
presume finalization of a proposal without notice and comment 
rulemaking. We provided the public with Addendum B and CY 2027 PFS 
Proposed Rule Fully Implemented PE RVUs for full transparency into 
implementation of these proposals. We also acknowledge that the formula 
displayed in step (20) of the published Sample Calculation of PE RVUs 
under Methodology for Selected Codes public use file indicated that the 
second part of the indirect PE allocator for CPT code 99213 is based on 
the work RVU but we note that the calculated value displayed in step 
(21) of the published file is correct. For the final rule, we note that 
our methodology public use files reflect all finalized proposals.
    After consideration of the public comments, we are finalizing our 
proposal to allocate indirect PE using both the work RVU and the 
clinical labor RVU for all services, with the exception of codes with 
10- and 90-day global periods, instead of just applying that 
methodology to those services that can be reported using technical, 
professional, and global components.

[[Page 70997]]

(3) Facility and Non-Facility Costs
    For procedures that can be furnished in a physician's office, as 
well as in a facility setting, where Medicare makes a separate payment 
to the facility for its costs in furnishing a service, we establish two 
PE RVUs: facility and non-facility. The methodology for calculating PE 
RVUs is generally the same for both the facility and non-facility RVUs 
but is applied independently to yield two separate PE RVUs. In 
calculating the PE RVUs for services furnished in a facility, we do not 
include resources that would generally not be provided by physicians 
when furnishing the service. For this reason, the facility PE RVUs are 
generally lower than the non-facility PE RVUs. In the CY 2026 PFS final 
rule (90 FR 49292 through 49296), we finalized a modification in the 
allocation of indirect PE to reduce the portion of the facility PE RVUs 
allocated based on work RVUs to half the amount allocated to non-
facility PE RVUs beginning in CY 2026.
(4) Services With Technical Components and Professional Components
    Diagnostic services are generally comprised of two components: a 
professional component (PC); and a technical component (TC). The PC and 
TC may be furnished independently or by different healthcare providers, 
or they may be furnished together as a global service. When services 
have separately billable PC and TC components, the payment for the 
global service equals the sum of the payment for the TC and PC. To 
achieve this, we use a weighted average of the ratio of indirect to 
direct costs across all the specialties that furnish the global 
service, TCs, and PCs; that is, we apply the same weighted average 
indirect percentage factor to allocate indirect expenses to the global 
service, PCs, and TCs for a service. (The direct PE RVUs for the TC and 
PC sum to the global direct PE RVUs.)
(5) PE RVU Methodology
    For a more detailed description of the PE RVU methodology, we 
direct readers to the CY 2010 PFS final rule with comment period (74 FR 
61745 through 61746). We also direct readers to the file titled 
``Calculation of PE RVUs under Methodology for Selected Codes'' which 
is available on our website under downloads for the CY 2027 PFS final 
rule at <a href="https://www.cms.gov/medicare/payment/fee-schedules/physician/federal-regulation-notices">https://www.cms.gov/medicare/payment/fee-schedules/physician/federal-regulation-notices</a>. This file contains a table that illustrates 
the calculation of PE RVUs as described in this final rule for 
individual codes.
(a) Setup File
    First, we create a setup file for the PE methodology. The setup 
file contains the direct cost inputs, the utilization for each 
procedure code at the specialty and facility/non-facility place of 
service level, and the specialty specific PE/HR data calculated from 
the surveys.
(b) Calculate the Direct Cost PE RVUs
    Sum the costs of each direct input.
    Step 1: Sum the direct costs of the inputs for each service.
    Step 2: Calculate the aggregate pool of direct PE costs for the 
current year. We set the aggregate pool of PE costs equal to the 
product of the ratio of the current aggregate PE RVUs to current 
aggregate work RVUs and the projected aggregate work RVUs.
    Step 3: Calculate the aggregate pool of direct PE costs for use in 
ratesetting. This is the product of the aggregate direct costs for all 
services from Step 1 and the utilization data for that service.
    Step 4: Using the results of Step 2 and Step 3, use the CF to 
calculate a direct PE scaling adjustment to ensure that the aggregate 
pool of direct PE costs calculated in Step 3 does not vary from the 
aggregate pool of direct PE costs for the current year. Apply the 
scaling adjustment to the direct costs for each service (as calculated 
in Step 1).
    Step 5: Convert the results of Step 4 to an RVU scale for each 
service. To do this, divide the results of Step 4 by the CF. Note that 
the actual value of the CF used in this calculation does not influence 
the final direct cost PE RVUs as long as the same CF is used in Step 4 
and Step 5. Different CFs would result in different direct PE scaling 
adjustments, but this has no effect on the final direct cost PE RVUs 
since changes in the CFs and the associated direct scaling adjustments 
offset one another.
(c) Create the Indirect Cost PE RVUs
    Create indirect allocators.
    Step 6: Based on the survey data, calculate direct and indirect PE 
percentages for each physician specialty.
    Step 7: Calculate direct and indirect PE percentages at the service 
level by taking a weighted average of the results of Step 6 for the 
specialties that furnish the service. Note that for services with TCs 
and PCs, the direct and indirect percentages for a given service do not 
vary by the PC, TC, and global service.
    We generally use an average of the 3 most recent years of available 
Medicare claims data to determine the specialty mix assigned to each 
code. Codes with low Medicare service volume require special attention 
since billing or enrollment irregularities for a given year can result 
in significant changes in specialty mix assignment. We finalized a 
policy in the CY 2018 PFS final rule (82 FR 52982 through 52983) to use 
the most recent year of claims data to determine which codes are low 
volume for the coming year (those that have fewer than 100 allowed 
services in the Medicare claims data). For codes that fall into this 
category, instead of assigning a specialty mix based on the specialties 
of the practitioners reporting the services in the claims data, we use 
the expected specialty that we identify on a list developed based on 
medical review and input from expert interested parties. We display 
this list of expected specialty assignments as part of the annual set 
of data files we make available as part of notice and comment 
rulemaking and consider recommendations from the RUC and other 
interested parties on changes to this list annually. Services for which 
the specialty is automatically assigned based on previously finalized 
policies under our established methodology (for example, ``always 
therapy'' services) are unaffected by the list of expected specialty 
assignments. We also finalized in the CY 2018 PFS final rule (82 FR 
52982 through 52983) a policy to apply these service-level overrides 
for both PE and MP, rather than one or the other category.
    In prior years, we reviewed information submitted during the 
proposed rule comment period regarding potential additions to the list 
of expected specialty assignments, to determine whether the specialty 
assignments commenters recommended were appropriate for the services in 
question. Our review process has been based on determining if the 
recommended specialty matched the dominant specialty in the claims 
data. However, we have long held reservations on whether this was the 
most accurate method for implementing updates to the expected specialty 
assignments list. Since these updates to the list were never formally 
proposed in the proposed rule of each calendar year, there was never an 
opportunity for interested parties to comment and provide feedback 
before the assignments were finalized in the final rule. We believe 
that it would provide greater transparency and more opportunities for 
public comment if additions to the expected specialty assignments list 
were instead proposed in each year's proposed rule.

[[Page 70998]]

    Therefore, we did not finalize any additions to the expected 
specialty assignments list in the CY 2026 PFS final rule (90 FR 49270). 
We stated that we would instead review the list of approximately 75 low 
volume HCPCS codes submitted by commenters and propose additions to the 
list in this year's CY 2027 PFS proposed rule. We will also review any 
submissions for inclusion to the expected specialty assignments list by 
the same February 10th deadline that we have finalized in the past for 
consideration of RUC recommendations and invoice-based updates to 
supply and equipment pricing. We believe that synchronizing submissions 
to the expected specialty assignments list for low volume services with 
the same annual date used for RUC recommendations and invoice 
submissions will help standardize the process, while also providing 
more opportunities for feedback from interested parties by going 
through the annual comment process.
    During the comment period for the CY 2026 PFS rule, several 
commenters stated that they had performed an analysis to identify all 
codes that meet the criteria to receive a specialty override under this 
CMS policy and drafted updated recommendations for codes that meet 
these criteria. Commenters stated that the purpose of assigning a 
specialty to these codes was to avoid the significant adverse impact on 
MP RVUs that results from errors in specialty utilization data 
magnified in representation (percentage) by small sample size. These 
commenters submitted a list of approximately 75 low volume HCPCS codes 
with recommended expected specialty assignments.
    After reviewing the information provided by the commenters to 
determine whether the specialty assignments they recommended were 
appropriate for the services in question, based on determining if the 
recommended specialty matches the dominant specialty in the claims 
data, we proposed the additions to the list of expected specialty 
assignments for low volume services identified in Table A-B1. We agree 
with the commenters that, based on claims data, CPT codes 33277 through 
33281 and 33287 through 33288 should be crosswalked to the Cardiac 
Electrophysiology specialty and that CPT codes 93584 through 93588 
should be crosswalked to the Interventional Cardiology specialty. We 
also agree with commenters that CPT code 23077 should be crosswalked to 
the Surgical Oncology specialty. However, we do not have PE/HR data for 
these specialties as they were not part of the PPIS when it was 
conducted in 2007; therefore, we are crosswalking these CPT codes to 
the closest available specialties (Cardiology for the first two groups 
of codes and All Physicians for CPT code 23077), as listed on Table A-
B1.
    We disagree with the commenters on a series of additional suggested 
assigned specialties. In each case, there was another specialty which 
was reported more than twice as often in the claims data as the 
specialty suggested by commenters and in some cases reported as much as 
five times as often. Therefore, we proposed to crosswalk CPT codes 
15135 and 41000 to the Otolaryngology specialty, CPT codes 26118 and 
26650 to the Orthopedic Surgery specialty, CPT codes 93025 and 93150 to 
the Cardiology specialty, and CPT codes 93152 and 93153 to the 
Pulmonary Disease specialty as these were the dominant specialties in 
the claims data. These crosswalks are included in Table A-B1.

BILLING CODE 4169-69-C
    Comment: Several commenters stated that they concurred with CMS 
that synchronizing submissions to the expected specialty assignments 
list for low volume services with the same annual date used for RUC 
recommendations and invoice submissions will help standardize the 
process, while also providing additional opportunities for feedback 
through annual rulemaking. Commenters stated that they would submit 
additional recommendations for CY 2028 rulemaking before the February 
10, 2027 deadline.
    Response: We appreciate the support for our proposed policy from 
the commenters.
    Comment: Several commenters disagreed with the CMS proposed 
specialty assignment for the 21 codes where CMS diverged from the RUC's 
recommended specialty. For CPT codes 15135, 26118, 26650, 93152, and 
93153,

[[Page 71001]]

commenters stated that, based on the description of work, the list of 
specialty societies that participated in the RUC survey process, and 
with respect to the whole population of patients who might receive this 
service, CMS should use the RUC's recommended specialty assignments 
even though they were not the top reported specialty in 2024 Medicare 
claims data.
    Response: We disagree with the commenters and continue to believe 
that the proposed specialty assignments are the more accurate choice 
for these CPT codes. As we stated in the CY 2018 PFS final rule, we 
agree that the use of service-level overrides for low volume services 
would help mitigate annual fluctuations and provide greater stability 
in the valuation of these services (82 FR 52982). We finalized the 
creation of this list of assigned specialty for low volume services at 
this time with the intention of minimizing these annual fluctuations in 
valuation, not with the goal of matching each CPT code to its idealized 
specialty. We believe that it is more accurate to assign specialties 
based on the actual billing practices for each CPT code as reflected in 
the claims data, not what might have been intended by the CPT Editorial 
Panel at the time of the code's creation. All five of the CPT codes 
listed by commenters were reported twice as often by the assigned 
specialty that we proposed as compared with the RUC's recommended 
specialty; in the case of CPT code 93152, Pulmonary Disease was 
reported roughly five times more often than the recommended Cardiac 
Electrophysiology. We therefore continue to believe that the proposed 
specialty assignments are the most accurate choices for these codes.
    Comment: Several commenters stated that for the approximately 15 
CPT codes in Table A-B1 that did not have PE/HR data, CMS should use 
the available MP premium data and crosswalk the assigned specialty for 
these codes as recommended by the RUC for MP purposes. The commenters 
stated that the proposed CMS crosswalks could still be used for PE 
purposes due to the lack of PE/HR data. Commenters made this request 
for CPT codes 23077, 33277-33281, 33287, 33288, 93025, 93150, and 
93584-93588.
    Response: We disagree with the commenters that CMS should establish 
separate PE and MP crosswalks for the specialty assignment in these 
cases where there is no PE/HR data available. We specifically finalized 
this policy in the CY 2018 PFS final rule that we would apply these 
service-level overrides for both PE and MP, rather than one or the 
other category. We provided rationale at that time, stating that this 
would simplify the implementation of service-level overrides for PE and 
MP, and would continue to address stakeholder concerns about the year-
to-year variability for low volume services (82 FR 52982-52983). Our 
rationale from the CY 2018 PFS final rule continues to apply, but we 
will continue to address stakeholder concerns as they arise.
    Comment: A commenter asked CMS to confirm that low-volume 
echocardiographic services are assigned to cardiology or pediatric 
cardiology rather than to a specialty with a materially different cost 
structure. The commenter requested that CMS provide the underlying 
utilization crosswalk for these assignments so societies can verify 
them.
    Response: As we noted in the proposed rule, the CPT codes 
associated with the Cardiac Electrophysiology specialty were all 
crosswalked to the Cardiology specialty due to a lack of PE/HR data. 
All of the proposed and finalized expected specialty assignments are 
included in the CY 2027 public use files associated with the PFS 
proposed and final rules as detailed previously.
    Comment: A commenter requested that CMS add several codes to the 
expected specialty assignment for low volume services list as part of 
CY 2028 rulemaking and assign thoracic surgery as their expected 
specialty.
    Response: We appreciate the feedback from the commenter, however we 
will consider these additional codes for inclusion to the expected 
specialty assignment list in next year's CY 2028 PFS proposed rule to 
allow for public comment.
    After consideration of the comments, we are finalizing the new 
additions to the expected specialty assignment list as proposed in 
Table A-B1.
    As noted in the proposed rule, the full list of expected specialty 
assignments is included in the CY 2027 public use files, which are 
available on the CMS website under downloads for the CY 2027 PFS final 
rule at <a href="https://www.cms.gov/medicare/payment/fee-schedules/physician/federal-regulation-notices">https://www.cms.gov/medicare/payment/fee-schedules/physician/federal-regulation-notices</a>.
    Step 8: Calculate the service level allocators for the indirect PEs 
based on the percentages calculated in Step 7. The indirect PEs are 
allocated based on the three components: the direct PE RVUs; the 
clinical labor PE RVUs; and the work RVUs.
    Under current policy, for most services the indirect allocator is: 
indirect PE percentage * (direct PE RVUs/direct percentage) + work 
RVUs.
    There are two situations where this formula is modified:
    <bullet> If the service is a global service (that is, a service 
with global, professional, and technical components), then the indirect 
PE allocator is: indirect percentage (direct PE RVUs/direct percentage) 
+ clinical labor PE RVUs + work RVUs.
    <bullet> If the clinical labor PE RVUs exceed the work RVUs (and 
the service is not a global service), then the indirect allocator is: 
indirect PE percentage (direct PE RVUs/direct percentage) + clinical 
labor PE RVUs.
    (Note: Under current policy, for global services, the indirect PE 
allocator is based on both the work RVUs and the clinical labor PE 
RVUs. We do this to recognize that, for the PC service, indirect PEs 
would be allocated using the work RVUs, and for the TC service, 
indirect PEs would be allocated using the direct PE RVUs and the 
clinical labor PE RVUs. This also allows the global component RVUs to 
equal the sum of the PC and TC RVUs.)
    For presentation purposes, in the examples in the download file 
titled ``Calculation of PE RVUs under Methodology for Selected Codes'', 
the formulas were divided into two parts for each service.
    <bullet> The first part does not vary by service and is the 
indirect percentage (direct PE RVUs/direct percentage).
    <bullet> Under current policy, the second part is either the work 
RVU, clinical labor PE RVU, or both depending on whether the service is 
a global service and whether the clinical PE RVUs exceed the work RVUs 
(as described earlier in this step).
    We note that for CY 2026, we finalized a change to the methodology 
so that when work RVUs are used to allocate indirect PE to the facility 
RVUs, they are assigned at one-half the amount allocated to the non-
facility PE RVUs for that same service. These PE methodology changes 
are discussed in greater detail in the CY 2026 PFS final rule (90 FR 
49292 through 49296).
    Proposed Step 8: Calculate the service level allocators for the 
indirect PEs based on the percentages calculated in Step 7. The 
indirect PEs are allocated based on the three components: the direct PE 
RVUs; the clinical labor PE RVUs; and the work RVUs.
    The proposed indirect allocator is: indirect PE percentage *(direct 
PE RVUs/direct percentage) + work RVUs + clinical labor RVUs. The 
proposed change, as detailed in the proposed rule (91 FR 43842 through 
44557), is to include both the work RVUs and clinical labor RVUs in the 
indirect allocator for all services, except for

[[Page 71002]]

codes with 10- and 90-day global periods, as opposed to including the 
work RVUs and clinical labor RVUs only for global services.
    We stated that, if this proposed policy were to be finalized, this 
Proposed Step 8 would replace the Step 8 listed in the proposed rule 
(91 FR 43842 through 44557). We note that step was also listed earlier 
in this final rule. For presentation purposes, in the examples in the 
download file titled ``Calculation of PE RVUs under Methodology for 
Selected Codes,'' the formulas were divided into two parts for each 
service.
    <bullet> The first part is the indirect percentage (direct PE RVUs/
direct percentage).
    <bullet> The second part is the sum of the work RVU and the 
clinical labor PE RVU, including the methodology change finalized in CY 
2026 for services performed in the facility setting (when work RVUs are 
used to allocate indirect PE to the facility RVUs, they are assigned at 
one-half the amount allocated to the non-facility PE RVUs for that same 
service).
    Apply a scaling adjustment to the indirect allocators.
    Step 9: Calculate the current aggregate pool of indirect PE RVUs by 
multiplying the result of step 8 by the average indirect PE percentage 
from the survey data.
    Step 10: Calculate an aggregate pool of indirect PE RVUs for all 
PFS services by adding the product of the indirect PE allocators for a 
service from Step 8 and the utilization data for that service.
    Step 11: Using the results of Step 9 and Step 10, calculate an 
indirect PE adjustment so that the aggregate indirect allocation does 
not exceed the available aggregate indirect PE RVUs and apply it to 
indirect allocators calculated in Step 8.
    Under current policy, calculate the indirect practice cost index 
(IPCI). We refer readers to the CY 2007 PFS final rule with comment 
period (71 FR 69633) for more information about the establishment of 
the IPCI.
    Step 12: Using the results of Step 11, calculate aggregate pools of 
specialty specific adjusted indirect PE allocators for all PFS services 
for a specialty by adding the product of the adjusted indirect PE 
allocator for each service and the utilization data for that service.
    Step 13: Using the specialty specific indirect PE/HR data, 
calculate specialty specific aggregate pools of indirect PE for all PFS 
services for that specialty by adding the product of the indirect PE/HR 
for the specialty, the work time for the service, and the specialty's 
utilization for the service across all services furnished by the 
specialty.
    Step 14: Using the results of Step 12 as the denominator and Step 
13 as the numerator, calculate the specialty specific indirect PE 
scaling factors.
    Step 15: Using the results of Step 14, calculate an indirect 
practice cost index at the specialty level by dividing each specialty 
specific indirect scaling factor by the average indirect scaling factor 
for the entire PFS.
    Step 16: Calculate the indirect practice cost index at the service 
level to ensure the capture of all indirect costs. Calculate a weighted 
average of the practice cost index values for the specialties that 
furnish the service. (Note: For services with TCs and PCs, we calculate 
the indirect practice cost index across the global service, PCs, and 
TCs. Under this method, the indirect practice cost index for a given 
service (for example, echocardiogram) does not vary by the PC, TC, and 
global service.)
    Step 17: Apply the service level indirect practice cost index 
calculated in Step 16 to the service level adjusted indirect allocators 
calculated in Step 11 to get the indirect PE RVUs.
    Proposal regarding Steps 12 through 17: We develop the indirect 
practice expense (PE) RVUs under the PFS to reflect the relative 
resources involved in furnishing the services. Since the implementation 
of the resource-based PE RVUs, we have assumed that aggregate specialty 
level practice costs derived primarily from the 2007 PE/HR survey data 
are a reasonable way to help establish the resource-based indirect PE 
RVUs. We have historically used that data both to allocate indirect 
costs to each code and to re-scale the resulting PE RVUs for each code 
at the end of the established methodology to ensure that the overall 
allocation of PE RVUs for each specialty across the PFS approximates 
those expected based on the index derived from the PE/HR survey data. 
Over time, however, we have identified various limitations of the 
survey data, especially as the data we use has become increasingly 
dated and are intrinsically limited to small, selective samples based 
on pre-determined assumptions about where costs are likely to differ, 
and, as we addressed in CY 2026 PFS rulemaking, have not been 
adequately updated. (We refer readers to an extended discussion of our 
concerns with and decision not to update this data in the CY 2026 PFS 
final rule at 90 FR 49286 through 49292.) This has resulted in a PE 
methodology that privileges the historic survey data over incorporation 
of more recent data about specific services and produces unpredictable 
and counterintuitive results that are not transparent to the public.
    Because we have taken various steps to improve the data used in the 
pricing inputs and the indirect allocation methodologies, we are 
proposing to remove the steps of the current methodology that rely on 
the indirect practice cost index (IPCI) from the calculation of the PE 
RVUs. We proposed this change because the steps of the current 
methodology that rely on the IPCI calculation effectively favor the 
aggregate specialty-level survey data over the code level inputs and 
allocators and consequently limit the influence of improvements to 
inputs and allocation methodologies. We proposed to implement this 
change over a 2-year transition period. Specifically, in the first 
year, only half of the measured variation in the IPCI will be applied 
to the indirect allocator. In the second year, CY 2028, the IPCI will 
no longer be applied.
    The steps of the current methodology that rely on the IPCI 
calculation are steps 12 through 17. Thus, under this proposal, steps 
12 through 17 would no longer be a part of the calculation, starting 
for CY 2028, and the total PE RVU, prior to the calculation of final PE 
RVUs described at Step 18, would be the sum of step 5 (Direct Cost PE 
RVUs) and step 11 (Indirect Cost PE RVUs).
    We received public comments on this proposal. The following is a 
summary of the comments we received and our responses.
    Comment: Many commenters supported removing the IPCI from the PE 
methodology and agreed with CMS that the underlying data are nearly two 
decades old and no longer representative of current practice costs. 
Several commenters agreed that eliminating the IPCI reduces unintended 
and opaque effects on PE RVUs, and supported the 2-year transition as 
an appropriate way to mitigate disruption while implementing a more 
accurate methodology. Multiple commenters strongly supported removal, 
explaining that the IPCI has historically amplified payment advantages 
for specialties with higher aggregate indirect costs, such as those 
tied to expensive equipment, while disadvantaging specialties whose 
costs are driven primarily by clinical labor activities. A commenter 
cited its own analysis of the CY 2026 facility-based payment change, 
finding that specialties with very low facility utilization saw an 
average 12.4 percent decrease in their IPCI values while specialties 
with very high facility utilization saw an average 32.2 percent 
increase. The commenter stated that some specialties experienced PE RVU 
decreases as a result of how facility-based services were paid that 
were

[[Page 71003]]

opposite of CMS's stated policy intentions and highlighted that the 
counterintuitive and seemingly unintended decrease in PE RVUs for some 
specialties as a result of the CY 2026 rule demonstrates that the IPCI 
can create winners and losers based on unrelated policy changes, rather 
than actual practice expenses. Other commenters expressed 
disappointment that CMS did not instead update the underlying PPI 
Survey data using more recent survey efforts, but supported removing 
the IPCI in the absence of adoption of the updated survey data because 
the current methodology privileges antiquated, aggregate specialty-
level survey data over code-level inputs and limits the influence of 
improvements to those inputs.
    The Medicare Payment Advisory Commission (MedPAC) also supported 
eliminating the IPCI, citing its June 2025 report to Congress 
recommending that CMS improve the accuracy of Medicare's relative 
payment rates by using timely data that reflect the costs of delivering 
care, and noting that the IPCI is calculated using PE/HR survey data 
collected nearly two decades ago. MedPAC further encouraged CMS to seek 
additional ways to reduce reliance on that survey data, observing that 
even after IPCI removal, direct PE RVUs would still be multiplied by a 
ratio of indirect-to-direct PE costs drawn from the specialties billing 
a service, meaning indirect PE RVUs would remain adjusted based on 
decades-old, specialty-reported data. MedPAC stated that forgoing 
specialty-specific practice expense data has the potential to improve 
payment accuracy and make routine updates more practicable, and cited 
the AMA's updated PPI and CPI Survey efforts as examples of the 
difficulty of collecting representative specialty-level data: low 
response rates led to data based on a small number of practices for 
some specialties, acceptance of practices that volunteered or were 
recruited to report data, and inconsistent consolidation of specialty 
categories. MedPAC stated that these concerns led them to support CMS's 
decision not to incorporate that updated survey data into the 
ratesetting process.
    Response: We appreciate the commenters' support and feedback on the 
proposal. We agree with the commenters that the CY 2026 facility 
indirect PE example illustrates precisely the type of unexpected effect 
that motivated CMS's proposal to remove the IPCI and believe that this 
is one of many examples that support removing the IPCI rather than 
preserving it. We also acknowledge that, while an updated survey may be 
preferable in principle, the data quality concerns with the available 
updated survey data support proceeding with removal of the IPCI now . 
We thank MedPAC for its support and its analysis of the continued role 
of PE/HR survey data in the indirect PE allocation. We agree with 
MedPAC that removing the IPCI does not fully eliminate CMS's reliance 
on this outdated survey data, as discussed further in the section. We 
may consider, in future rulemaking, additional approaches to reduce 
reliance on specialty-specific PE/HR data, consistent with the 
direction of the policies we are finalizing this year.
    Comment: Some commenters stated the belief that the IPCI was used 
to allocate indirect PE and expressed concern that the specialty-
specific differences in indirect costs continue to exist, but noted 
that CMS proposed to eliminate the IPCI without offering a reasonable, 
empirically supported alternative. Some commenters stated that CMS 
should not assume indirect costs are similar or equal across 
specialties without supporting data, citing certain specialties that 
have indirect costs exceeding what would be expected under a code-
level-only approach, and recommended that CMS instead conduct its own 
updated survey of indirect costs rather than eliminate the IPCI.
    Response: Some commenters seem to be confused that we proposed to 
remove all specialty-specific PE/HR data and we want to clarify that is 
not the case. As described previously, we still use the specialty-
specific data to allocate indirect PE, but removing the IPCI means we 
would no longer re-scale the resulting PE RVUs to an index derived from 
the outdated survey data. The IPCI functions to force changes that 
would otherwise occur in indirect PE (that is payments for office 
overhead such as administrative staff and rent that cannot be directly 
attributed to individual services) back to the status quo, which is 
currently based on the physician overhead contained in the 2007 AMA 
Physician Practice Information (PPI) Survey. However, the continued use 
of the IPCI has resulted in a PE methodology that privileges the 
historic survey data over incorporation of more recent data about 
specific services, limits the influence of improvements to inputs and 
allocation methodologies, and produces unpredictable and 
counterintuitive results that are not transparent to the public. We 
proposed to remove the IPCI from our methodology for CY 2027 over a 2-
year transition period, though for now we would retain the use of the 
survey data in other places in the methodology, as discussed 
previously. We continue to believe this proposed change will improve 
the transparency and stability of PE RVUs over time and better position 
us to make necessary refinements to the PE methodology to improve the 
accuracy of valuation of the PE portion of services paid under the PFS.
    In the proposed rule, we acknowledged that the IPCI, because it is 
rooted in static PE/HR data, effectively resulted in stabilizing year-
to-year changes in PE RVUs, especially due to changes in input 
valuations and changes to allocation methodologies, which is why we 
proposed the PE stabilization adjustment to further improve 
predictability and reduce volatility within the PE RVUs. We note that 
our proposal to eliminate the IPCI was not solely based on the age of 
the survey data, but also based on the fact that the IPCI can result in 
counter-intuitive payment outcomes and is a barrier to broader payment 
changes.
    We do not agree that CMS should instead conduct a new survey of 
specialty-level indirect costs before removing the IPCI. As discussed 
previously in connection with MedPAC's comment, recent efforts to 
collect updated, representative specialty-level practice expense data 
encountered low response rates, relied on practices that volunteered or 
were recruited rather than being randomly sampled, and inconsistently 
consolidated specialty categories. We do not believe commissioning 
another specialty-level survey would resolve these structural 
difficulties, and we do not believe it is appropriate to delay 
improvements to the current methodology. We also do not agree that 
removing the IPCI assumes indirect costs are identical across 
specialties. Rather, our proposal reflects the conclusion that the IPCI 
is not a reliable means of capturing any genuine specialty specific 
variation in indirect costs that may exist, because it re-scales a 
code's indirect PE based on the mix of specialties that happen to bill 
it in claims data, not based on a direct measurement or acceptable 
proxy for the indirect costs those specialties incur in furnishing that 
specific service. We continue to believe that removing the IPCI results 
in PE RVUs that more accurately reflect the indirect resources a 
service requires.
    Comment: Many commenters opposed removal of the IPCI or asked CMS 
to delay finalizing the proposal. Several commenters asked CMS to 
explain why a 2-year transition is sufficient given the scale of 
redistribution among specialties, and asked CMS to compare

[[Page 71004]]

payment trajectories under 2-year and 4-year transitions, noting that 
CMS has historically used four-year transitions for significant PE 
methodology changes, including the CY 2007 transition to the bottom-up 
PE methodology and the CY 2010 incorporation of Physician Practice 
Information Survey data. A commenter, while not opposing removal of the 
IPCI outright, stated that CMS should publish detailed impact analyses 
and supporting data before finalizing the proposal, and that if CMS 
proceeds, a stabilization mechanism is essential to prevent disruptions 
in PE that could jeopardize practice stability and patient access to 
care. Other commenters stated that CMS has not published code- and 
specialty-level impact analyses of the IPCI removal in isolation from 
the other proposed PE changes, making it difficult for stakeholders to 
evaluate the proposal's actual effects, and requested that CMS delay 
finalization until it demonstrates, through empirical validation and 
transparent impact analyses, that removing the IPCI produces more 
accurate resource-based relativity rather than assuming that 
eliminating an older data source necessarily improves accuracy.
    Response: We recognize that the aggregate specialty impact tables 
published with the proposed rule do not isolate the effect of IPCI 
removal from our other PE proposals because all three policies affect 
PE RVUs concurrently. We agree with commenters that these proposals are 
interconnected and interact with one another, and therefore, we could 
not publish disaggregated specialty impact tables of each proposal 
individually without misconstruing their combined impact when they are 
implemented together. We note that, in the past, we have published 
impact tables for different alternatives considered, but we do not 
typically publish disaggregated policy impacts because of how these 
policies may interact.
    We note that we published code-level impacts in the CY 2027 PFS 
Proposed Rule Fully Implemented PE RVUs public use file. While we have 
used 4-year transitions in the past to temper impacts over time, the 
proposed 5% PE stabilization adjustment proposed for CY 2027 already 
functions to phase in the changes to the PE RVUs and temper impacts 
over time. For example, for codes that experience large increases or 
decreases as a result of our PE methodology proposals, and are not the 
result of a revaluation, the PE stabilization adjustment effectively 
serves to phase in those changes over many years, often exceeding the 
4-year transition we have used in the past. We acknowledge that this 
may not be the desired implementation for specialties that benefit from 
the proposed PE methodology changes, but we believe this results in a 
reasonable balance between safeguarding against significant, unintended 
payment volatility while still allowing meaningful progress toward more 
accurate PE valuations within a reasonable timeframe. We note that this 
2-year transition, which phases in the removal of steps 12 through 17, 
is a distinct mechanism from the PE stabilization adjustment discussed 
later in the section, which separately caps the year-to-year change in 
any code's PE RVU. The two mechanisms work together: the 2-year 
transition sets the pace at which the IPCI's influence is phased out of 
the methodology, while the PE stabilization adjustment independently 
moderates how quickly any resulting change reaches a given code's final 
PE RVU.
    Comment: A commenter requested that CMS detail how we would treat 
Non-Physician Practitioners (NPPs) under this new methodology. They 
stated that NPPs' specialty is obscured in the claims data because they 
are not able to be associated with their specialty when they enroll.
    Response: As stated later in the section, to calculate the PE and 
MP RVUs, we exclude certain specialties, such as NPPs paid at a 
percentage of the PFS and low volume specialties, from the calculation. 
However, these specialties are still included to calculate the BN 
adjustment.
    After consideration of public comments, we are finalizing the 
proposal to remove steps 12 through 17 that rely on the IPCI from the 
calculation of the PE RVUs over a 2-year transition period, as 
proposed.
(d) Calculate the Final PE RVUs
    Step 18: Under current policy, add the direct PE RVUs from Step 5 
to the indirect PE RVUs from Step 17 and apply the final PE budget 
neutrality (BN) adjustment. The final PE BN adjustment is calculated by 
comparing the sum of steps 5 and 17 to the aggregate work RVUs scaled 
by the ratio of current aggregate PE and work RVUs. This adjustment 
ensures that all PE RVUs in the PFS account for the fact that certain 
specialties are excluded from the calculation of PE RVUs but included 
in maintaining overall PFS BN. (See ``Specialties excluded from 
ratesetting calculation'' later in this final rule). Under the proposed 
policy, add the direct cost PE RVUs from Step 5 to the indirect cost PE 
RVUs from Step 11 and apply the final PE BN adjustment.
    Proposed Step 19: Calculate and apply the PE stabilization 
adjustment for each PE RVU by comparing the result of step 18 with the 
results of the prior year's PE RVUs from step 18. As described in the 
proposed rule, we proposed to remove the IPCI from the PE methodology, 
which we believe will improve the transparency and stability of PE RVUs 
over time. However, we recognize that the IPCI, because it is rooted in 
static PE/HR data, effectively resulted in stabilizing year-to-year 
changes in PE RVUs, especially due to changes in input valuations and 
changes to allocation methodologies. We have long noted that extreme 
volatility in PE RVUs can have unintended consequences and distortions. 
To mitigate volatility that could otherwise occur, we proposed a PE 
stabilization adjustment to further improve predictability and reduce 
volatility within the PE RVUs. Specifically, we proposed that the PE 
RVU calculated after the application of the cognitive services floor 
and any adjustments that occur outside of the PE methodology will be 
subject to a cap and will not increase or decrease by more than 5 
percent each year. In the proposed Step 19 we would compare the PE RVU 
after the application of the cognitive services floor and any code-
level adjustments in the current ratesetting year to the allocation 
methodology from the prior year and then apply the 5 percent cap. We 
note that the proposed PE stabilization adjustment in Proposed Step 19 
will be applied prior to the statutory phase-in of significant RVU 
reductions required by Section 1848(c)(7) of the Act, discussed in more 
detail later in this section, which limits all codes that are not new 
or revised to a 19 percent decrease in total RVU in an individual 
calendar year. Therefore, a code may be impacted by both the PE 
stabilization adjustment and the statutory phase-in, meaning a code's 
PE RVU may ultimately differ by greater than the PE stabilization 
adjustment detailed in proposed Step 19.
    This proposed adjustment would not apply to new and revised codes 
or codes formerly contractor priced that are newly nationally priced, 
because it is not clear what the comparison PE RVU would be for those 
codes. Because we believe the benefits of the PE stabilization 
adjustment would ideally apply to new and revised codes and newly 
nationally priced codes, we sought comment on an approach that would 
allow us to expand the PE stabilization adjustment to these categories 
of codes.
    Additionally, the proposed PE stabilization adjustment would not

[[Page 71005]]

apply to revalued codes because we believe the statutory phase-in 
sufficiently limits large reductions to individual codes undergoing 
review and/or revaluation, and limits the amount of time a revalued 
code would remain under or overvalued by being significantly 
constrained from reductions found to be appropriate through 
revaluation.
    We received public comments on this proposal. The following is a 
summary of the comments we received and our responses.
    Comment: Many commenters stated that CMS should identify the codes 
subject to the PE stabilization adjustment and the codes' final PE 
RVUs, similar to our published public use file of codes subject to the 
statutory phase-in of significant RVU reductions.
    Response: We appreciate commenters' feedback and note that we are 
publishing this list as a public use file with this final rule, which 
can be found under the Downloads section for this rule at <a href="https://www.cms.gov/medicare/payment/fee-schedules/physician/federal-regulation-notices">https://www.cms.gov/medicare/payment/fee-schedules/physician/federal-regulation-notices</a>.
    Comment: A commenter stated that they support the idea of adding a 
PE stabilization adjustment to the PE RVU methodology to mitigate 
volatility in PE RVUs and avoid unintended consequences. The commenter 
requested further explanation of how the proposed adjustment would 
operate and its relationship to the existing phase-in of significant 
RVU reductions. Multiple commenters requested that we exempt increases 
to direct PE inputs from the PE stabilization adjustment when supported 
by higher supply or equipment prices validated through the invoice 
submission process to ensure that direct PE resource costs are fully 
reflected in PE RVUs. Another commenter supported the proposal to 
establish a PE stabilization adjustment to safeguard against unintended 
payment swings while allowing CMS to continue modernizing the PE 
methodology, but stated that a 2 to 3 percent adjustment would be more 
appropriate, particularly for CY 2027 because CMS proposed multiple 
changes to the PE methodology. The commenter also supported CMS' 
consideration of extending the PE stabilization adjustment to new and 
revised codes and codes that are newly nationally priced and encouraged 
CMS to develop an appropriate methodology for providing comparable 
protection to newly established services without compromising the 
accuracy of their initial valuations. Another commenter requested that 
CMS extend the proposed PE stabilization adjustment to revalued codes, 
or at a minimum, to codes revalued on a single direct PE input cost 
change rather than a full RUC survey, and stated that the statutory 
phase-in of significant RVU reductions is not a sufficient cushion. 
Another commenter stated that we should modify the PE stabilization 
adjustment to either have a fixed duration or larger percentage 
because, as proposed, limiting annual changes to 5 percent would mean 
that, for the commenter's most commonly billed codes, it would take 
nearly a decade of phase-in before the RVUs fully reflected their 
current, updated valuation. The commenter recommends a 4-year, 5 
percent PE stabilization adjustment that allows providers to prepare 
for the updated code values.
    Response: We agree with the commenters that changes due to 
revaluation, such as changes to a code's direct PE prices, should be 
exempt from the PE stabilization adjustment. As noted previously, the 
PE stabilization adjustment will not apply to revalued codes, such as 
the commenter's example of PE input changes, because we believe the 
statutory phase-in sufficiently limits large reductions in total RVUs 
to individual codes undergoing review and/or revaluation. This 
exemption also limits the amount of time a revalued code would remain 
under- or overvalued by being significantly constrained from increases 
or reductions found to be appropriate through revaluation. Although 
revalued codes are excluded from the PE stabilization adjustment, 
significant decreases in total RVUs are statutorily phased-in for codes 
that are not new or revised. As the commenter mentioned, for CY 2027, 
we proposed changes to the supply code SA119's price, which decreased 
the PE RVU for CPT code 97610 (Low frequency, non-contact, non-thermal 
ultrasound, including topical application(s), when performed, wound 
assessment, and instruction(s) for ongoing care, per day). Because this 
reduction was the result of revaluation of the code's supply input, CPT 
code 97610 is exempt from the PE stabilization adjustment, but the 
statutory phase-in of significant total RVU decreases does apply 
because it is an existing code, not new or revised, whose total RVU 
decrease is greater than 19 percent. We do not agree with the commenter 
that we should apply the PE stabilization adjustment in these instances 
because it would extend the amount of time that a code would remain 
constrained from increases or reductions found to be appropriate 
through revaluation. Conversely, the PE RVU for CPT code 99285 
(Emergency department visit for the evaluation and management of a 
patient, which requires a medically appropriate history and/or 
examination and high level of medical decision making) will increase as 
the result of our proposed PE methodology changes (that is, removal of 
IPCI). It is not subject to the 19 percent statutory phase-in of 
significant RVU decreases because it is an increase, but it is subject 
to the 5 percent PE stabilization adjustment and the increase will be 
effectively phased-in by that policy. We encourage interested parties 
to review the additional public use file provided with this final rule 
that details the codes subject to the PE stabilization adjustment.
    We appreciate the commenters' request for further explanation of 
how the PE stabilization adjustment interacts with the existing 
statutory phase-in of significant RVU reductions. As illustrated by the 
examples noted previously, the two policies operate independently and 
apply to different sources of RVU change: the statutory phase-in 
applies to a code's total RVU decrease, and is implemented on the PE 
RVU, while the PE stabilization adjustment applies specifically to 
changes in PE RVUs, typically resulting from methodological changes 
rather than code-by-code changes (that is, the sum-based indirect PE 
allocation and removal of the IPCI proposed for CY 2027), and does not 
apply when the change results from revaluation. A code may therefore be 
subject to one, both, or neither policy depending on the source and 
magnitude of its RVU changes for a given year, although we note that it 
is unlikely for a code to be subject to both since revalued codes are 
exempt from the PE stabilization adjustment, which is the most likely 
source of significant decreases in total RVUs greater than 19 percent. 
The PE stabilization adjustment is primarily intended to mitigate 
volatility and improve predictability of the PE RVUs that result from 
changes to the PE methodology.
    We appreciate the commenters' feedback about considering 
alternative higher and lower percentages and a fixed duration of the PE 
stabilization adjustment. However, as discussed previously, we believe 
5 percent is a reasonable balance between safeguarding against 
significant, unintended payment volatility while still allowing 
meaningful progress toward more accurate PE valuations within a 
reasonable timeframe, and we are finalizing the PE stabilization 
adjustment at 5 percent as proposed. We are not extending the PE 
stabilization adjustment to new, revised, or newly nationally priced 
codes at this time

[[Page 71006]]

because it is not clear what the comparison PE RVU would be for those 
codes. However, we remain interested in a methodology that would extend 
the PE stabilization adjustment to these services and invite 
stakeholders to share methodological approaches for us to consider in 
future rulemaking.
    After consideration of public comments, we are finalizing the 
proposals to remove steps 12 through 17 that rely on the IPCI from the 
calculation of the PE RVUs over a 2-year transition period, and to add 
a new step to the PE methodology to apply a 5 percent PE stabilization 
adjustment to the PE RVUs, as proposed.
    Step 20: Apply the phase-in of significant RVU reductions and its 
associated adjustment. Section 1848(c)(7) of the Act specifies that for 
services that are not new or revised codes, if the total RVUs for a 
service for a year would otherwise be decreased by an estimated 20 
percent or more as compared to the total RVUs for the previous year, 
the applicable adjustments in work, PE, and MP RVUs must be phased in 
over a 2-year period. In implementing the phase-in, we consider a 19 
percent reduction as the maximum 1-year reduction for any service not 
described by a new or revised code. This approach limits the year 1 
reduction for the service to the maximum allowed amount (that is, 19 
percent) and then phases in the remainder of the reduction. To comply 
with section 1848(c)(7) of the Act, we adjust the PE RVUs to ensure 
that the total RVUs for all services that are not new or revised codes 
decrease by no more than 19 percent, and then apply a relativity 
adjustment to ensure that the total pool of aggregate PE RVUs remains 
relative to the pool of work and MP RVUs. For a more detailed 
description of the methodology for the phase-in of significant RVU 
changes, we refer readers to the CY 2016 PFS final rule with comment 
period (80 FR 70927 through 70931).
    In summary, for CY 2027, we proposed, and have now finalized our 
proposals to:
    <bullet> Modify step 8 to calculate indirect PE based on both work 
RVUs and clinical labor RVUs for all services except 10- and 90-day 
global period codes;
    <bullet> Remove steps 12 through 17 that rely on the IPCI from the 
calculation of the PE RVUs over a 2-year transition period, and;
    <bullet> Add a new step to apply a PE stabilization adjustment to 
the PE RVUs (new step 19).
(e) Setup File Information
    <bullet> Specialties excluded from ratesetting calculation: To 
calculate the PE and MP RVUs, we exclude certain specialties, such as 
NPPs paid at a percentage of the PFS and low volume specialties, from 
the calculation. These specialties are included to calculate the BN 
adjustment. They are displayed in Table A-B2.
BILLING CODE 4169-69-P

[[Page 71007]]

[GRAPHIC] [TIFF OMITTED] TR09NO26.070

BILLING CODE 4169-69-C
    <bullet> Crosswalk certain low volume physician specialties: 
Crosswalk the utilization of certain specialties with relatively low 
PFS utilization to the associated specialties.
    <bullet> Physical therapy utilization: Crosswalk the utilization 
associated with all physical therapy services to the specialty of 
physical therapy.
    <bullet> Identify professional and technical services not 
identified under the usual technical component (TC) and professional 
component (PC or 26) modifiers: Flag the services that are PC and TC 
services but do not use TC and PC/26 modifiers (for example, 
electrocardiograms). This flag associates the PC and TC with the 
associated global code for use in creating the indirect PE RVUs. For 
example, the professional service, CPT code 93010 (Electrocardiogram, 
routine ECG with at least 12 leads; interpretation and report only), is 
associated with the global service, CPT code 93000 (Electrocardiogram, 
routine ECG with at least 12 leads; with interpretation and report).
    <bullet> Payment modifiers: In the CY 2013 PFS final rule with 
comment period (77 FR 68901), we introduced a more detailed methodology 
for adjusting volume and time to account for payment modifiers and 
other special payment rules, such as multiple procedure payment 
reductions, in the utilization data. We proposed that, beginning in CY 
2027, we would utilize a new approach to account for payment modifiers 
and other special payment rules. For each paid claim line, we would 
calculate the ratio of allowed charges to the national PFS payment 
amount. This would account for differences resulting from payment 
modifiers and other special payment rules, as well as differences in 
geography. We proposed to use the same ratio to adjust time, rather 
than a separate calculation under our current methodology, with the 
exception of anesthesia, for which we calculate time using only 
procedures with modifiers indicating they are personally

[[Page 71008]]

performed. These proposed changes will allow us to more accurately 
capture any combination of modifiers and special payment rules and 
automatically account for updates in modifiers and/or special payment 
rules in future years. These proposed changes have a very minimal 
impact on the resulting PE RVUs but will produce a more accurate 
result. As under our current methodology, the adjusted volume will be 
displayed in the utilization public use file that is posted in 
conjunction with each PFS rule.
    Comment: Several commenters identified large declines in the total 
allowed charges displayed for certain specialties, such as Pathology 
Independent Laboratories, and Physical and Occupational Therapy, in 
Table D-B5 ``Estimated Impact on Total Allowed Charges by Specialty'' 
of the CY 2027 PFS proposed rule (91 FR 44244-44248). Commenters stated 
that nothing in the PFS proposed rule appeared to explain declines of 
this scale and the figures seemed inconsistent with the considerably 
smaller percentage payment effects reported elsewhere in the table. 
Commenters asked whether these estimates arose from a reporting error 
or resulted from a change in data or methodology in the proposed rule.
    Response: We appreciate commenters raising this issue. We 
identified and corrected a minor technical error that impacted the 
adjusted utilization of codes that are frequently furnished in multiple 
MTUS (miles, time, units), such as codes reported in time or square 
centimeter increments. This technical error in the adjusted utilization 
resulted in erroneous decreased allowed charges in Table D-B5 of the 
proposed rule for specialties that bill these types of codes like the 
specialties that commenters raised concerns about. We appreciate the 
feedback from interested parties in identifying this error, which has 
been corrected in the adjusted utilization for the final rule.
    Comment: Some commenters noted that CMS has published detailed 
modifier-specific utilization data in the public use files with each 
proposed and final PFS rule for decades. Commenters expressed concern 
that CMS excluded all modifiers except for -26, -TC, and -53 in the 
utilization data public use file for this proposed rule, which 
commenters say is particularly challenging when CMS proposed changes to 
modifier 25 and for HCPCS code G2211 to instead be reported with 
modifiers. Commenters recommend that CMS change the ``CY 2027 2025 
Utilization Data Crosswalked to 2027'' to include all modifiers to 
maintain a sufficient level of transparency for interested parties. 
Several commenters requested that CMS consider providing additional 
supporting materials such as utilization crosswalk files between the 
current and previous years. The commenters also requested the 
restoration of utilization file fields (such as undiscounted allowed 
services, PE, MP, and work discounted allowed services, and complete 
modifier columns).
    Response: We no longer display the work, PE, and MP adjusted 
allowed services columns in the Utilization Data file because of our 
proposed changes to the adjusted utilization process, described 
previously. The proposed approach to calculate the ratio of allowed 
charges to the national PFS payment amount to adjust utilization means 
that all current payment modifiers, special payment rules, and 
geographic adjustments are accounted for in column G of the utilization 
data public use file. Additionally, the new columns H and I are 
discussed in the proposed rule at 91 FR 44248. Because the modifier -25 
(column H) and modifier B1 (referred to as MOD1 in the proposed rule) 
and modifier B2 (referred to as MOD2 in the proposed rule) (column I) 
proposals impact adjusted utilization, they are also accounted for in 
the utilization data public use file, but we believed it would be best 
to publish these new columns separately to help commenters understand 
the impact of the proposals. As a result, Column J is the cumulative 
adjusted utilization of columns G, H, and I that was used in CY 2027 
PFS ratesetting, effectively accounting for our proposed new approach 
to adjust utilization for current payment modifiers, geographic 
adjustments, and special payment rules, plus our proposed changes to 
modifier 25, modifier B1 (referred to as MOD1 in the proposed rule) and 
modifier B2 (referred to as MOD2 in the proposed rule). As the 
commenter mentioned, modifiers -26, -TC, and -53 (for select services) 
remain in the utilization data file because codes with these modifiers 
are listed with separate base RVUs in the payment files (that is, 
Addendum B) before any modifiers are applied, which distinguishes them 
from all other payment modifiers and geographic adjustments which 
typically impact payment for a claim at the time of processing.
    We appreciate the commenters' feedback about the additional 
supporting materials that would be helpful for interested parties and 
may consider for future rulemaking. In an effort to improve 
transparency, we are including both allowed services and MTUS in the 
file for the final rule. We note that, for the proposed rule, the 
unadjusted and adjusted allowed services columns were inadvertently 
mislabeled and actually represented unadjusted and adjusted MTUS. For 
the purposes of ratesetting, for non-anesthesia services, MTUS 
represent the unit for which PFS rates are established and are the 
correct measure of service utilization. For the final rule, we have 
added allowed services to the file for reference since it reflects the 
number of times the service was provided, regardless of the number of 
units reported for each service, although it is not used in 
ratesetting. Anesthesia services do not have RVUs or payment amounts 
listed in our payment files but are included in the total RVU pool used 
to establish budget neutrality. To accomplish this, we use allowed 
services and calculate RVUs based on average allowed charges by service 
to capture anesthesia spending within the ratesetting process. 
Therefore, the file does not report MTUS for anesthesia services, only 
allowed services, which are reflected in the value in Column J of 
adjusted utilization file, which is used in ratesetting.
    Comment: A commenter did not support the proposed new approach to 
account for payment modifiers and other special payment rules and 
requested that CMS eliminate all geographic adjustments from the PFS 
except for those designed to achieve a specific public policy goal (for 
example, to encourage physicians to practice in underserved areas). To 
the extent the proposed new approach to accounting for payment 
modifiers and other special payment rules also accounts for and 
potentially adjusts RVUs based on geography, the commenter opposed the 
proposal and would, instead, recommend that CMS continue to use its 
current approach or otherwise find an approach that does not further 
geographically adjust Medicare payments.
    Response: Section 1848(e)(1)(A) of the Act requires us to develop 
Geographic Practice Cost Indices (GPCIs) to measure relative cost 
differences among localities compared to the national average for each 
of the three fee schedule components (that is, work, practice expense 
(PE), and malpractice (MP)), therefore, we do not have the statutory 
authority to eliminate all geographic adjustments from the PFS. 
Additionally, utilization at the geographic level has always been used 
in PFS ratesetting, but the new proposed approach allows us to more 
accurately capture any combination of modifiers, geographic 
adjustments, and special payment rules in the claims data that 
underpins PFS ratesetting.

[[Page 71009]]

    Comment: A commenter stated that, when CMS transitioned to the PE 
methodology in CY 2007, utilization was assigned exclusively to 
physical therapy, not to the previously combined ``physical and 
occupational therapy practice expense pool.'' All prior crosswalks had 
been to PT and OT, and no policy rationale was given for dropping OT 
from the crosswalk in 2007. The commenter stated that this methodology 
resulted in all therapy treatment codes where OT or speech language 
pathology (SLP) account for the majority of billing volume, receiving 
PT's IPCI, which is the lowest of the three therapy disciplines. The 
commenter stated that even under the CY 2027 proposal to remove the 
IPCI over 2 years, the crosswalk continues to matter during the 
transition year as half the IPCI will still be applied, and the 
utilization crosswalk ensures that it will be applied at PT's lower 
index rather than the actual specialty blend, and requested for CMS to 
remove the following step when establishing the final CY 2027 setup 
file: ``Physical therapy utilization: Crosswalk the utilization 
associated with all physical therapy services to the specialty of 
physical therapy''.
    Response: We did not propose to change how utilization is assigned 
to the therapy specialties for IPCI purposes, a policy which was 
finalized in CY 2007 rulemaking (71 FR 69635), and we are not 
finalizing a change since CY 2027 will be the only transition year 
before the elimination of the IPCI for CY 2028. We believe that this 
issue identified by the commenter provides an example of the public 
confusion and counterintuitive results associated with the IPCI which 
is why we proposed to transition away from its use.
    After consideration of the comments, we are finalizing the new 
approach to account for payment modifiers and other special payment 
rules, as proposed, with the minor technical error identified corrected 
for the final rule.
    <bullet> Work RVUs: The setup file contains the work RVUs from this 
final rule.
(6) Equipment Cost Per Minute
    The equipment cost per minute is calculated as:

(1/(minutes per year * usage)) * price * ((interest rate/( 1-(1/((1 + 
interest rate) - life of equipment)))) + maintenance)

Where:

minutes per year = maximum minutes per year if usage were continuous 
(that is, usage = 1); generally, 150,000 minutes.
usage = variable, see discussion later in this final rule.
price = price of the particular piece of equipment.
life of equipment = useful life of the particular piece of 
equipment.
maintenance = factor for maintenance; 0.05.
interest rate = variable, see discussion later in this proposed 
rule.

    Usage: We currently use an equipment utilization rate assumption of 
50 percent for most equipment, with the exception of expensive 
diagnostic imaging equipment, for which we use a 90 percent assumption 
as required by section 1848(b)(4)(C) of the Act.
    Useful Life: In the CY 2005 PFS final rule we stated that we 
updated the useful life for equipment items primarily based on the 
AHA's ``Estimated Useful Lives of Depreciable Hospital Assets'' 
guidelines (69 FR 66246). The most recent edition of these guidelines 
was published in 2018. This reference material provides an estimated 
useful life for hundreds of different types of equipment, the vast 
majority of which fall in the range of 5 to 10 years, and none of which 
are lower than 2 years in duration. We believe that the updated 
editions of this reference material remain the most accurate source for 
estimating the useful life of depreciable medical equipment.
    In the CY 2021 PFS final rule, (85 FR 84482 through 84483) we 
finalized a proposal to treat equipment life durations of less than 1 
year as having a duration of 1 year for the purpose of our equipment 
price per minute formula. In the rare cases where items are replaced 
every few months, we noted that we believe it is more accurate to treat 
these items as disposable supplies with a fractional supply quantity as 
opposed to equipment items with very short equipment life durations. 
For a more detailed discussion of the methodology associated with very 
short equipment life durations, we refer readers to the CY 2021 PFS 
final rule (85 FR 84482 through 84483).
    <bullet> Maintenance: We finalized the 5 percent factor for annual 
maintenance in the CY 1998 PFS final rule with comment period (62 FR 
33164). As we previously stated in the CY 2016 PFS final rule with 
comment period (80 FR 70897), we do not believe the annual maintenance 
factor for all equipment is precisely 5 percent, and we concur that the 
current rate likely understates the true cost of maintaining some 
equipment. We also noted that we believe it likely overstates the 
maintenance costs for other equipment. When we solicited comments 
regarding data sources containing equipment maintenance rates, 
commenters could not identify an auditable, robust data source that CMS 
could use on a wide scale. We noted that we did not believe voluntary 
submissions regarding the maintenance costs of individual equipment 
items would be an appropriate methodology for determining costs. As a 
result, in the absence of publicly available datasets regarding 
equipment maintenance costs or another systematic data collection 
methodology for determining a different maintenance factor, in the 
proposed rule, we did not propose a variable maintenance factor for 
equipment cost per minute pricing as we did not believe that we have 
sufficient information at present. We noted in the CY 2026 PFS proposed 
rule (90 FR 32593) that we would continue to investigate potential 
avenues for determining equipment maintenance costs across a broad 
range of equipment items.
    <bullet> Interest Rate: In the CY 2013 PFS final rule with comment 
period (77 FR 68902), we updated the interest rates used in developing 
an equipment cost per minute calculation (see 77 FR 68902 for a 
thorough discussion of this issue). The interest rate was based on the 
Small Business Administration (SBA) maximum interest rates for 
different categories of loan size (equipment cost) and maturity (useful 
life). The interest rates are listed in Table A-B3.

[[Page 71010]]

    We did not propose and we are not finalizing any changes to the 
equipment interest rates for CY 2027.
3. Adjusting RVUs To Match the PE Share of the Medicare Economic Index 
(MEI)
    We have long stated that we believe that the MEI is the best 
measure available to determine the relative weights of the three 
components in payments under the PFS--work, practice expense (PE), and 
malpractice (MP). Accordingly, we believe that to ensure that the PFS 
payments reflect the relative resources in each of these PFS components 
as required by section 1848(c)(3) of the Act, the RVUs used in 
developing rates should reflect the same weights in each component as 
the cost share weights in the Medicare Economic Index (MEI). 
Accordingly, we have finalized to accomplish this (78 FR 74241 through 
74242) by holding the work RVUs constant and adjusting the PE RVUs, MP 
RVUs, and conversion factor (CF) to produce the appropriate balance in 
RVUs among the three PFS components and payment rates for individual 
services, that is, that the total RVUs on the PFS are proportioned to 
approximately 51 percent work RVUs, 45 percent PE RVUs, and 4 percent 
MP RVUs. Historically, as the MEI cost shares are updated, we have 
proposed to modify steps 3 and 10 to adjust the aggregate pools of PE 
costs (direct PE in step 3 and indirect PE in step 10) in proportion to 
the change in the PE share in the MEI cost share weights, and to 
recalibrate the relativity adjustment that we apply in step 18 as 
described in the CY 2023 PFS final rule (87 FR 69414 and 69415) and CY 
2014 PFS final rule (78 FR 74236 and 74237). The most recent 
recalibration was done for the CY 2014 RVUs.
    However, due to overarching concerns with the data as described in 
the CY 2026 PFS final rule (90 FR 49287 through 49293) and our 
previously described policy goal to balance PFS payment stability and 
predictability with incorporating new data through routine updates to 
the MEI, we finalized our proposal to maintain the current PE/HR and 
2006-based MEI cost shares (rather than transitioning to the 2017-based 
MEI cost shares). Additionally, for CY 2027, we proposed to continue to 
use the current PE/HR and 2006-based MEI cost shares for CY 2027 PFS 
ratesetting. We received public comments on this proposal. The 
following is a summary of the comments we received and our responses.
    Comment: Few commenters requested that we implement the 2024 PPI 
and CPI Survey PE/HR data and cost shares in PFS ratesetting for CY 
2027. Several commenters requested that we update the cost shares to 
the most currently available MEI. Several commenters supported our 
proposal to continue using the current PE/HR and 2006-based MEI cost 
shares for CY 2027 PFS ratesetting, or until the 2024 PPI Survey data 
may be considered. Some commenters stated that we should not implement 
the PPI and CPI Survey data until the issues discussed in the CY 2026 
final rule have been addressed.
    Response: We agree with commenters that we should continue using 
the current PE/HR and 2006-based MEI cost shares for CY 2027 PFS 
ratesetting, and may consider the commenters' feedback in future 
rulemaking as we consider data to update the cost shares.
    After consideration of the public comments, we are finalizing our 
proposal to continue to use the current PE/HR and 2006-based MEI cost 
shares for CY 2027 PFS ratesetting.
4. Changes to Direct PE Inputs for Specific Services
    This section focuses on specific PE inputs. The direct PE inputs 
are included in the CY 2027 direct PE input public use files, which are 
available on the CMS website under downloads for the CY 2027 PFS final 
rule at <a href="https://www.cms.gov/medicare/payment/fee-schedules/physician/federal-regulation-notices">https://www.cms.gov/medicare/payment/fee-schedules/physician/federal-regulation-notices</a>.
a. Standardization of Clinical Labor Tasks
    As we noted in the CY 2015 PFS final rule with comment period (79 
FR 67640 through 67641), we continue to make improvements to the direct 
PE input database to provide the number of clinical labor minutes 
assigned for each task for every code in the database instead of only 
including the number of clinical labor minutes for the preservice, 
service, and post service periods for each code. In addition to 
increasing the transparency of the information used to set PE RVUs, 
this level of detail would allow us to compare clinical labor times for 
activities associated with services across the PFS, which we believe is 
important to maintaining the relativity of the direct PE inputs. This 
information would facilitate the identification of the usual numbers of 
minutes for clinical labor tasks and the identification of exceptions 
to the usual values. It would also allow for greater transparency and 
consistency in the assignment of equipment minutes based on clinical 
labor times. Finally, we believe that the detailed information can be 
useful in maintaining standard times for particular clinical labor 
tasks that can be applied consistently to many codes as they are valued 
over several years, similar in principle to physician preservice time 
packages. We believe that setting and maintaining such standards would 
provide greater consistency among codes that share the same clinical 
labor tasks and could improve the relativity of values among codes. For 
example, as medical practice and technologies change over time, 
standards could be updated simultaneously for all codes with the 
applicable clinical labor tasks instead of waiting for individual codes 
to be reviewed.
    In the CY 2016 PFS final rule with comment period (80 FR 70901), we 
solicited comments on the appropriate standard minutes for the clinical 
labor tasks associated with services that use digital technology. After 
consideration of comments received, we finalized standard times for 
clinical labor tasks associated with digital imaging at 2 minutes for 
``Availability of prior images confirmed'', 2 minutes for ``Patient 
clinical information and questionnaire reviewed by technologist, order 
from physician confirmed and

[[Page 71011]]

exam protocoled by radiologist'', 2 minutes for ``Review examination 
with interpreting MD'', and 1 minute for ``Exam documents scanned into 
PACS'' and ``Exam completed in RIS system to generate billing process 
and to populate images into Radiologist work queue.'' In the CY 2017 
PFS final rule (81 FR 80184 through 80186), we finalized a policy to 
establish a range of appropriate standard minutes for the clinical 
labor activity, ``Technologist QCs images in PACS, checking for all 
images, reformats, and dose page.'' These standard minutes will be 
applied to new and revised codes that make use of this clinical labor 
activity when they are reviewed by us for valuation. We finalized a 
policy to establish 2 minutes as the standard for the simple case, 3 
minutes as the standard for the intermediate case, 4 minutes as the 
standard for the complex case, and 5 minutes as the standard for the 
highly complex case. These values were based upon a review of the 
existing minutes assigned for this clinical labor activity; we 
determined that 2 minutes is the duration for most services and a small 
number of codes with more complex forms of digital imaging have higher 
values. We also finalized standard times for a series of clinical labor 
tasks associated with pathology services in the CY 2016 PFS final rule 
with comment period (80 FR 70902). We do not believe these activities 
would be dependent on the number of blocks or batch size, and we 
believe that the finalized standard values accurately reflect the 
typical time it takes to perform these clinical labor tasks.
    In reviewing the RUC-recommended direct PE inputs for CY 2019, we 
noticed that the 3 minutes of clinical labor time traditionally 
assigned to the ``Prepare room, equipment and supplies'' (CA013) 
clinical labor activity were split into 2 minutes for the ``Prepare 
room, equipment and supplies'' activity and 1 minute for the ``Confirm 
order, protocol exam'' (CA014) activity. We proposed to maintain the 3 
minutes of clinical labor time for the ``Prepare room, equipment and 
supplies'' activity and remove the clinical labor time for the 
``Confirm order, protocol exam'' activity wherever we observed this 
pattern in the RUC-recommended direct PE inputs. Commenters explained 
in response that when the new version of the PE worksheet introduced 
the activity codes for clinical labor, there was a need to translate 
old clinical labor tasks into the new activity codes, and that a prior 
clinical labor task was split into two of the new clinical labor 
activity codes: CA007 (Review patient clinical extant information and 
questionnaire) in the preservice period, and CA014 (Confirm order, 
protocol exam) in the service period. Commenters stated that the same 
clinical labor from the old PE worksheet was now divided into the CA007 
and CA014 activity codes, with a standard of 1 minute for each 
activity. We agreed with commenters that we would finalize the RUC-
recommended 2 minutes of clinical labor time for the CA007 activity 
code and 1 minute for the CA014 activity code in situations where this 
was the case. However, when reviewing the clinical labor for the 
reviewed codes affected by this issue, we found that several of the 
codes did not include this old clinical labor task, and we also noted 
that several of the reviewed codes that contained the CA014 clinical 
labor activity code did not contain any clinical labor for the CA007 
activity. In these situations, we believe that the three total minutes 
of clinical staff time would be more accurately described by the CA013 
``Prepare room, equipment and supplies'' activity code, and we 
finalized these clinical labor refinements. We direct readers to the 
discussion in the CY 2019 PFS final rule (83 FR 59463 through 59464) 
for additional details.
    Following the publication of the CY 2020 PFS proposed rule, a 
commenter expressed concern with the published list of common 
refinements to equipment time. The commenter stated that these 
refinements were the formulaic result of applying refinements to the 
clinical labor time and did not constitute separate refinements; the 
commenter requested that CMS no longer include these refinements in the 
table published each year. In the CY 2020 PFS final rule, we agreed 
with the commenter that these equipment time refinements did not 
reflect errors in the equipment recommendations or policy discrepancies 
with the RUC's equipment time recommendations. However, we believed it 
was important to publish the specific equipment times that we were 
proposing (or finalizing in the case of the final rule) when they 
differed from the recommended values due to the effect these changes 
can have on the direct costs associated with equipment time. Therefore, 
we finalized the separation of the equipment time refinements 
associated with changes in clinical labor into a separate table of 
refinements. We direct readers to the discussion in the CY 2020 PFS 
final rule (84 FR 62584) for additional details.
    Historically, the RUC has submitted a ``PE worksheet'' that details 
the recommended direct PE inputs for our use in developing PE RVUs. The 
format of the PE worksheet has varied over time, and among the medical 
specialties developing the recommendations. These variations have made 
it difficult for the RUC's development and our review of code values 
for individual codes. Beginning with its recommendations for CY 2019, 
the RUC mandated the use of a new PE worksheet for its recommendation 
development process that standardizes the clinical labor tasks and 
assigns them a clinical labor activity code. We believe the RUC's use 
of the new PE worksheet in developing and submitting recommendations 
helps us simplify and standardize the hundreds of clinical labor tasks 
currently listed in our direct PE database. To facilitate rulemaking 
for CY 2027, we are displaying the Labor Task Detail public use file 
that contains the current listing of clinical labor activity codes. 
This file is available on the CMS website under downloads for the CY 
2027 PFS final rule at <a href="https://www.cms.gov/medicare/payment/fee-schedules/physician/federal-regulation-notices">https://www.cms.gov/medicare/payment/fee-schedules/physician/federal-regulation-notices</a>.
b. Updates to Prices for Existing Direct PE Inputs
    In the CY 2011 PFS final rule with comment period (75 FR 73205), we 
finalized a process to act on public requests to update equipment and 
supply price and equipment useful life inputs through annual 
rulemaking, beginning with the CY 2012 PFS proposed rule. Beginning in 
CY 2019 and continuing through CY 2022, we conducted a market-based 
supply and equipment pricing update using information developed by our 
contractor which updated pricing recommendations for approximately 1300 
supplies and 750 equipment items currently used as direct PE inputs. 
Given the potentially significant changes in payment that would occur, 
in the CY 2019 PFS final rule, we finalized a policy to phase in our 
use of the new direct PE input pricing over a 4-year period using a 25/
75 percent (CY PFS 2019), 50/50 percent (CY PFS 2020), 75/25 percent 
(CY PFS 2021), and 100/0 percent (CY PFS 2022) split between new and 
old pricing. We believe that implementing the proposed updated prices 
with a 4-year phase-in would improve payment accuracy while maintaining 
stability and allowing interested parties to address potential concerns 
about changes in payment for particular items. This 4-year transition 
period to update supply and equipment pricing concluded in CY 2022; for 
a more detailed discussion, we refer readers to the CY 2019 PFS final 
rule

[[Page 71012]]

with comment period (83 FR 59473 through 59480).
    For CY 2027, we proposed to update the price of nine supplies and 
two equipment items in response to the public submission of invoices 
following the publication of the CY 2026 PFS final rule. These supply 
and equipment items with updated prices are listed in the valuation of 
specific codes section of the final rule under Table A-D9, CY 2027 
Invoices Received for Existing Direct PE Inputs.
    These proposed pricing updates included a request from the RUC to 
update the pricing of the moderate sedation pack (SA044) to more 
accurately reflect its components. The RUC determined that a sterile 
gown is not needed as part of the moderate sedation pack, however, a 
regular staff gown should be included to protect the sedation provider 
from all body fluids, substance, and excretions. The RUC also requested 
that a mask would be an appropriate addition in the sedation pack, 
resulting in a price change from the current $19.20, minus the $5.13 
sterile gown, plus the $1.19 staff gown and $0.43 mask, for a new total 
price of $15.69. We proposed this $15.69 price for the SA044 moderate 
sedation pack which is reflected in Table A-D9, CY 2027 Invoices 
Received for Existing Direct PE Inputs.
    Additionally, we received a potentially misvalued code (PMVC) 
nomination for SA119 kit, low frequency ultrasound wound therapy (MIST) 
and proposed an updated supply cost from $320.18 to $100 for SA119. We 
refer readers to section II.D. of this final rule for more information 
about this proposal.
    Comment: Many commenters stated that they approved of the proposed 
pricing changes included in the CY 2027 PFS proposed rule. Different 
commenters stated their approval for the proposed change in pricing for 
the aquatic therapy pool (EQ050), the liposorber system (EQ174), the 
Universal Detection Kit (SA117), the Varithena admin pack (SA125), the 
Varithena (foam) (SD324), the Dorsal SI Joint Arthrodesis Implant 
(SD356), and the Esketamine (56 mg vial) (SH109) and Esketamine (84 mg 
vial) (SH110) supplies.
    Response: We appreciate the support for our proposed pricing from 
the commenters.
    Comment: A commenter stated that the existing supply cost for the 
purified protein derivative (SH059) supply falls short of covering the 
cost of the product, leading many pediatric practices to stop 
purchasing the product and potentially reducing patient access to 
tuberculosis skin testing. The commenter requested that CMS increase 
the supply cost for the SH059 purified protein derivative supply to 
better reflect the actual cost paid by practices and align payment with 
current market pricing; to this effect, the commenter submitted five 
invoices with updated pricing information.
    Response: We appreciate the submission of these invoices from the 
commenter to assist in updating the price of the SH059 supply. In 
reviewing these invoices, we determined that they averaged out to a 
price of $138.60 by selling 10 doses in 1 mL vials, a substantial 
increase over the current $26.11 price for the SH059 supply. We were 
able to find unit prices of $36.70 and $51.44 when the product was sold 
in 50 doses of 5 mL vials which average together for a price of $44.07. 
Since we believe it would be more typical to purchase the SH059 in 
larger batch sizes given the considerable cost savings, we are 
finalizing an update in the price at the averaged $44.07 rate, which we 
note still constitutes a pricing increase of roughly 70% for the SH059 
supply.
    Comment: A commenter submitted invoices reflecting the costs 
associated with furnishing the SleepioRx product, together with a 
request to create a new direct PE supply code that refers to validated 
pricing for SleepioRx. The commenter stated that there was a lack of 
consistent contractor pricing for HCPCS code G0552 (Supply of digital 
mental health treatment device and initial education and onboarding, 
per course of treatment that augments a behavioral therapy plan) which 
uses this supply item and therefore creates an access barrier to 
Medicare beneficiaries with insomnia. The commenter urged CMS to 
establish a direct PE input supply code for SleepioRx, based on the 
submitted invoices and provide billing guidance to the Medicare 
Administrative Contractors (MACs).
    Response: We appreciate the submission of these invoices from the 
commenter. We note that a supply code for this product was finalized 
last year in the CY 2026 PFS final rule, using the name ``Digital 
mental health device (insomnia)'' and using the supply code SD386 (90 
FR 49460). This supply is currently not assigned to any CPT codes since 
HCPCS code G0552 is contractor priced and therefore cannot include any 
direct PE inputs; we did not propose to establish national pricing for 
HCPCS code G0552 and we are not finalizing a change in its contractor 
priced status at this time. However, we will update the price of the 
SD386 supply based on the invoices submitted by the commenters at a new 
price of $400.00. The SD386 supply is listed along with the other 
updated supply and equipment prices under Table A-D9, CY 2027 Invoices 
Received for Existing Direct PE Inputs.
    Comment: A commenter requested that CMS establish new direct PE 
supply and equipment codes for the TearCare System, a technology that 
is used to perform the interventional procedure reported with CPT code 
0563T (Evacuation of meibomian glands, using heat delivered through 
wearable, open-eye eyelid treatment devices and manual gland 
expression, bilateral) to treat dry eye disease (DED) due to meibomian 
gland dysfunction (MGD). The commenter specified that they were not 
requesting that CMS establish national pricing for CPT code 0563T, 
instead stating that establishing supply and equipment codes for these 
devices would provide greater transparency and consistency in 
valuation, support more uniform reimbursement policies nationwide, and 
better align payment with the resources associated with performing the 
procedure among the Medicare Administrative Contractors (MACs). The 
commenter submitted 16 invoices to support the establishment of these 
new supply and equipment codes associated with the resources used to 
furnish CPT code 0563T.
    Response: We appreciate the submission of these invoices from the 
commenter with additional pricing information. After reviewing the 
invoices, we are finalizing the establishment of a new supply code for 
Smart Lids (SD397) at a price of $1000 and a new equipment code for a 
Smart Hub (EQ423) at a price of $6583.33 based on an average of the 
submitted invoices. As the commenter noted, these new direct PE inputs 
are currently not assigned to any CPT codes since CPT code 0563T is 
contractor priced and therefore cannot include any direct PE inputs. 
However, we have added them to the ratesetting database as requested by 
the commenter and they will appear in Table A-D10: CY 2027 Invoices 
Received for New Direct PE Inputs.
    Comment: Several commenters submitted a series of invoices in 
support of establishing nonfacility pricing for CPT code 66984 
(Extracapsular cataract removal with insertion of intraocular lens 
prosthesis (1 stage procedure), manual or mechanical technique (eg, 
irrigation and aspiration or phacoemulsification); without endoscopic 
cyclophotocoagulation) along with related CPT codes 65820, 66174, 
66982, 66989, and 66991. Commenters stated that these invoices 
substantiated the direct PE costs of

[[Page 71013]]

performing cataract surgery and requested that CMS use them to develop 
nonfacility pricing for these codes.
    Response: Although we appreciate the submission of these invoices 
from the commenters, we did not propose to establish nonfacility 
pricing for CPT code 66984 or any of the other related codes listed by 
the commenters. The submitted invoices included pricing for several 
dozen supply and equipment items, including some costs which are 
considered to be indirect under the current PE methodology such as 
building construction costs and service/licensing fees. It is unclear 
whether these invoices were intended to update the pricing for current 
supply and equipment items or establish new supply/equipment codes, as 
well as which items were intended to be associated with cataract 
surgery. We are not finalizing the creation of nonfacility pricing for 
CPT code 66984 or any of the other related codes listed by the 
commenters at this time; we remind interested parties that if they have 
reason to believe that individually services are inaccurately priced, 
we encourage them to submit a request under the potentially misvalued 
code initiative discussed elsewhere in this rule.
(1) Invoice Submission
    We remind readers that we routinely accept public submissions of 
invoices as part of our process for developing payment rates for new, 
revised, and potentially misvalued codes. Often, these invoices are 
submitted in conjunction with the RUC-recommended values for the codes. 
To be included in a given year's proposed rule, we generally need to 
receive invoices by the same February 10th deadline we noted for 
consideration of RUC recommendations. However, as noted in the proposed 
rule we considered invoices submitted as public comments during the 
comment period following the publication of the CY 2027 PFS proposed 
rule and will consider any invoices received after February 10th or 
outside of the public comment process as part of our established annual 
process for requests to update supply and equipment prices. Interested 
parties are encouraged to submit invoices with their public comments 
or, if outside the notice and comment rulemaking process, via email at 
<a href="/cdn-cgi/l/email-protection#94c4d1cbc4e6fdf7f1cbddfae4e1e0cbc1e4f0f5e0f1d4f7f9e7bafcfce7baf3fbe2"><span class="__cf_email__" data-cfemail="b6e6f3e9e6c4dfd5d3e9ffd8c6c3c2e9e3c6d2d7c2d3f6d5dbc598dedec598d1d9c0">[email&#160;protected]</span></a>.
(2) Supply Pack Pricing Update
    Interested parties previously notified CMS that they identified 
numerous discrepancies between the aggregated cost of some supply packs 
and the individual item components contained within. The interested 
parties indicated that CMS should rectify these mathematical errors as 
soon as possible to ensure that the sum correctly matches the totals 
from the individual items, and they recommended that we resolve these 
pricing discrepancies in the supply packs during CY 2024 rule. The AMA 
RUC convened a workgroup on this subject and submitted recommendations 
to update pricing for a series of supply packs along with the RUC's 
comment letter for the CY 2024 rule cycle.
    We appreciated the additional information and RUC workgroup 
recommendations regarding discrepancies in the aggregated cost of some 
supply packs. However, due to the projected significant cost revisions 
in the pricing of supply packs and because we did not propose to 
address supply pack pricing in the CY 2024 proposed rule, we stated in 
the CY 2024 final rule that this issue would be better addressed in 
future rulemaking. For example, the cleaning and disinfecting endoscope 
pack (SA042) is included as a supply input in more than 300 HCPCS 
codes, which could have a sizable impact on the overall valuation of 
these services, and which was not incorporated into the proposed RVUs 
published for the CY 2024 proposed rule. We stated that interested 
parties would be better served if we comprehensively addressed this 
topic during future rulemaking in which commenters could provide 
feedback in response to proposed pricing updates (88 FR 78833 through 
78834).
    For CY 2025, we proposed implementing the supply pack pricing 
update and associated revisions as recommended by the RUC's workgroup 
(89 FR 97726 through 97727). We proposed to update the pricing of the 
``pack, cleaning and disinfecting, endoscope'' (SA042) supply from 
$19.43 to $31.29, to update the pricing of the ``pack, drapes, 
cystoscopy'' (SA045) supply from $17.33 to $14.99, to update the 
pricing of the ``pack, ocular photodynamic therapy'' (SA049) supply 
from $16.35 to $26.35, to update the pricing of the ``pack, urology 
cystoscopy visit'' (SA058) supply from $113.70 to $37.63, and to update 
the pricing of the ``pack, ophthalmology visit (w-dilation)'' (SA082) 
supply from $3.91 to $2.33. As recommended by the RUC workgroup, we 
also proposed to delete the ``pack, drapes, laparotomy (chest-
abdomen)'' (SA046) supply entirely. The updated prices for these supply 
packs were listed in the valuation of specific codes section of this 
rule under Table A-B5, CY 2025 Invoices Received for Existing Direct PE 
Inputs (89 FR 97852).
    In accordance with the RUC workgroup's recommendations, we also 
proposed to create eight new supply codes, including components 
contained within previously existing supply packs. Aside from the SB056 
supply, which is a replacement in several HCPCS codes for the deleted 
SA046 supply pack, all of these new supplies are not included as 
standalone direct PE inputs in any current HCPCS codes, as they are, 
again, components contained within previously existing supply packs. We 
proposed to add:
    <bullet> The kit, ocular photodynamic therapy (PDT) (SA137) supply 
at a price of $26.00 as a component of the SA049 supply pack;
    <bullet> The Abdominal Drape Laparotomy Drape Sterile (100 in x 72 
in x 124 in) (SB056) supply at a price of $8.049 as a replacement for 
the SA046 supply pack;
    <bullet> The drape, surgical, legging (SB057) supply at a price of 
$3.284 as a component of the SA045 supply pack;
    <bullet> The drape, surgical, split, impervious, absorbent (SB058) 
supply at a price of $8.424 as a component of the SA045 supply pack;
    <bullet> The post-mydriatic spectacles (SB059) supply at a price of 
$0.328 as a component of the SA082 supply pack;
    <bullet> The y-adapter cap (SD367) supply at a price of $0.352 as a 
component of the SA049 supply pack;
    <bullet> The ortho-phthalaldehyde 0.55 percent (for example, Cidex 
OPA) (SM030) supply at a price of $0.554 as a component of the SA042 
supply pack; and
    <bullet> The ortho-phthalaldehyde test strips (SM031) supply at a 
price of $1.556 as a component of the SA042 supply pack.
    The new supply pack component items were listed in the valuation of 
specific codes section of the rule under Table A-B8, CY 2025 PFS (89 FR 
97722) New Invoices (89 FR 97853).
    We also proposed the following additional supply substitutions 
based on the recommendations of the RUC workgroup. We proposed to 
remove the deleted SA046 supply pack and replace it with the drape, 
sterile, fenestrated 16in x 29in (SB011) supply for CPT codes 19020, 
19101, 19110, 19112, 20101, and 20102. We proposed to remove the 
deleted SA046 supply pack and replace it with two supplies--the drape, 
sterile, three-quarter sheet (SB014) and the drape, towel, sterile 18in 
x 26in (SB019)--for CPT codes 19000 and 60300. We proposed to remove 
the deleted SA046 supply pack

[[Page 71014]]

and replace it with 2 supplies--the drape, towel, sterile 18in x 26in 
(SB019) and the newly created Abdominal Drape Laparotomy Drape Sterile 
(100 in x 72 in x 124 in) (SB056) supply--for CPT codes 22510, 22511, 
22513, and 22514. We proposed to remove the deleted SA046 supply pack 
without replacing it with anything for CPT code 22526; the RUC 
workgroup did not make a recommendation on what to do with CPT code 
27278, which also previously contained the SA046 supply pack. 
Therefore, we also proposed not to replace the SA046 supply pack with 
any supplies for this code. The RUC workgroup also recommended removing 
the SA046 supply pack from CPT code 64595 with no replacement; however, 
this code was recently reviewed at the April 2022 RUC meeting and it no 
longer includes the SA046 supply.
    In the comments on the CY 2025 PFS proposed rule (89 FR 97727), 
several commenters supported the proposed supply pack pricing update as 
recommended by the RUC workgroup, however they indicated concern over 
the proposed decrease in the price of the urology cystoscopy visit pack 
(SA058) from $113.70 to $37.63. The commenters stated that the proposed 
pricing reduction in the SA058 supply could result in drastic payment 
rate cuts for physicians performing cystoscopy services in the office 
setting. The commenters requested that CMS either delay the pricing 
update or phase-in the supply pack changes over a 4-year period like it 
has done for other PE changes with significant redistributive effects, 
allowing independent urology practices to better prepare for the 
negative financial impact this change will have.
    After considering these comments, we agreed that the use of a 
phased-in transition period would be appropriate to allow practitioners 
to adjust to the updated pricing of these supplies. During our previous 
supply and equipment pricing update in the CY 2019 PFS final rule (83 
FR 59475), we finalized a policy to phase in any updated pricing that 
we established during the 4-year transition period for very commonly 
used supplies and equipment, such as sterile gloves (SB024) or exam 
tables (EF023), even if invoices were provided as part of the formal 
review of a code family. Based on this previously established policy, 
we finalized the use of a pricing transition for three supply packs in 
Table A-B4. 
[GRAPHIC] [TIFF OMITTED] TR09NO26.072

    Following the same pattern as our previous supply/equipment and 
clinical labor pricing updates, we finalized the implementation of this 
pricing transition over 4 years such that one-quarter of the difference 
between the current price and the fully phased-in price is implemented 
for CY 2025 PFS (89 FR 97722), one-third of the difference between the 
CY 2025 PFS (89 FR 97722) price and the final price is implemented for 
CY 2026 PFS, and one-half of the difference between the CY 2026 price 
and the final price is implemented for CY 2027, with the new direct PE 
prices fully implemented for CY 2028. For the other proposed supply 
packs, the cystoscopy drapes pack (SA045) is only included in seven 
HCPCS codes and the ocular photodynamic therapy pack (SA049) is only 
included in a single HCPCS code which do not meet these criteria 
established in previous rulemaking and described previously in this 
section. Therefore, we finalized each of them at their updated pricing 
for CY 2025 PFS (89 FR 97722) as proposed in the proposed rule. We 
believe that the use of this pricing transition will minimize any 
potential disruptive effects during the 4-year transition period that 
could be caused by other sudden shifts in RVUs due to the high number 
of services that make use of these very common supply packs.
    Several commenters also stated that although five incomplete packs 
would have their pricing updated in the proposed rule, mathematical 
errors still remained for a number of additional supply packs. 
Commenters stated that only 3 of the 18 affirmed packs were priced 
correctly to match their components and provided tables showing the 
pricing of an additional 15 packs that needed mathematical correction 
by deconstructing the packs to determine the correct price through 
summing their individual components. Commenters requested that CMS 
initiate a correction of the packs pricing such that the sum of the 
individual components match the price of the corresponding pack as 
detailed in Table A-B5.

[[Page 71015]]

[GRAPHIC] [TIFF OMITTED] TR09NO26.073

    While we shared the concerns of the commenters regarding the need 
for accuracy in the pricing of these supply packs, we had reservations 
about their potential for pricing disruptions. Ten of these supply 
packs are included in the direct PE inputs for at least 100 HCPCS 
codes, and three of the packs are included in more than 1000 HCPCS 
codes. Many of these pricing updates would lead to drastic changes in 
pricing for these supply packs which are included in hundreds of HCPCS 
codes, such as the SA051 pelvic exam pack decreasing in price from 
$20.16 to $2.81 (-86 percent) and the SA048 minimum multi-specialty 
visit pack decreasing in price from $5.02 to $1.98 (-61 percent). We 
were particularly concerned that these changes in supply pack pricing 
could lead to significant shifts in the overall PE RVU for affected 
HCPCS codes, without these proposed rates appearing in the proposed 
rule or allowing any opportunity for public comment.
    Therefore, we did not finalize pricing updates for these additional 
15 supply packs as requested by commenters. We anticipated returning to 
this subject in future rulemaking to allow any changes in associated 
pricing for HCPCS codes to appear in the proposed rule and provide an 
opportunity for the public to comment. Should these supply pack pricing 
updates be proposed in future rulemaking, we anticipated that we might 
propose the same pricing transition described previously due to the 
number of potentially affected HCPCS codes. We finalized all of the 
other supply pack pricing changes as proposed, with the exception of 
the 4--year pricing transition for three supply packs as described 
previously in this section.
    For CY 2026, we proposed to continue implementing the supply pack 
pricing update and associated revisions as previously recommended by 
the RUC's workgroup. We proposed to update the price of the 15 supply 
packs detailed in Table A-B5 which were received too late in CY 2025 
PFS (89 FR 97722) to allow for proposed pricing or public comment. In 
the case of the surgical instruments cleaning pack (SA043), the 
moderate sedation pack (SA044) and the small ortho drapes pack (SA081), 
the proposed pricing update is modest enough that we proposed these 
supplies move immediately to their final prices for CY 2026.
    For the 12 other supply packs, we proposed that they be 
incorporated into the muti-year supply pack pricing transition 
finalized in CY 2025 rulemaking. Rather than having two separate 4-year 
pricing transitions associated with supply packs, we proposed that 
these 12 additional supply packs fold into the previous pricing 
transition using the same methodology, such that one-third of the 
difference between the CY 2025 PFS (89 FR 97722) price and the final 
price is implemented for CY 2026, and one-half of the difference 
between the CY 2026 price and the final price is implemented for CY 
2027, with the new direct PE prices fully implemented for CY 2028 (89 
FR 97728). With the inclusion of the SA042, SA058, and SA082 supply 
packs which began their pricing transition for CY 2025, we proposed the 
total supply pack pricing update detailed in Table A-B6.

[[Page 71016]]

    Table A-B6 also includes the hydrophilic guidewire (SD089) supply 
which we proposed to transition in pricing over 3 years given its 
inclusion in approximately 100 HCPCS codes. We continue to believe that 
the use of this pricing transition will minimize any potential 
disruptive effects during the transition period that could be caused by 
other sudden shifts in RVUs due to the high number of services that 
make use of these very common supply items. After consideration of the 
public comments, we finalized our supply pack pricing policies as 
proposed in the CY 2026 PFS final rule (90 FR 49284).
    For CY 2027, as stated in the proposed rule, these supply packs 
will continue with the third year of the previously finalized 4-year 
transition process as detailed in Table A-B6. In the proposed rule we 
noted that as is the case with other supply and equipment pricing, we 
would consider invoices associated with these supply packs which were 
submitted as public comments during the comment period following the 
publication of the CY 2027 PFS proposed rule as part of our established 
annual process for requests to update supply and equipment prices. We 
also encouraged interested parties to submit invoices with their public 
comments or, if outside the notice and comment rulemaking process, via 
email at <a href="/cdn-cgi/l/email-protection#7a2a3f252a0813191f2533140a0f0e252f0a1e1b0e1f3a19170954121209541d150c"><span class="__cf_email__" data-cfemail="3a6a7f656a4853595f6573544a4f4e656f4a5e5b4e5f7a59574914525249145d554c">[email&#160;protected]</span></a>.
    Comment: A commenter stated that they supported the continuing 
phase-in transition of supply pack pricing, specifically mentioning the 
SA041, SA042, SA048, SA052, SA053, and SA054 supply packs.
    Response: We appreciate the support for our previously finalized 
policy from the commenter.
    Comment: Several commenters stated that CMS should stop the 
continued pricing transition for the pelvic exam supply pack (SA051) 
and the cystoscopy visit supply pack (SA058). Commenters stated that 
these supply reductions were disconnected from actual practice costs 
and reductions in payment could create access barriers and push 
procedures into hospital outpatient departments where Medicare and 
patients generally pay more. Commenters requested that CMS freeze the 
price for these supply packs at their CY 2026 values and reconsider 
documentation of invoice pricing for these supplies.
    Response: We share the concerns of the commenters regarding the 
large decreases in pricing associated with the SA051 and SA058 supply 
packs, which is why we finalized the use of a phased-in transition 
period in the CY 2025 PFS final rule (89 FR 97722). We note that the 
pricing of these supply packs was already finalized in the CY 2025 PFS 
final rule, with the four-year implementation continuing to take place 
in CY 2027. However, we also believe in the importance of valuing 
supply items at the most accurate market-based pricing available, and 
therefore we cannot continue to price these supply packs at rates much 
higher than the cost of the individual components that make up the 
total packs. We welcome the submission of updated invoices and other 
cost data associated with these supply packs for potential inclusion in 
future rulemaking; we note that we did not receive any invoices from 
commenters supporting different pricing for the SA051 and SA058 supply 
packs.
c. Technical Corrections to Direct PE Input Database and Supporting 
Files
    Following the publication of the CY 2026 PFS final rule, the RUC 
submitted a potential technical correction issue related to global 
period assignment for approximately three dozen codes. The RUC stated 
that these codes had long descriptors which indicated that they were 
add-on codes ``(List separately in addition to code for primary 
procedure)''; however, these codes were assigned the XXX global period 
instead of the ZZZ global period. The RUC requested that CMS consider 
assigning the ZZZ global period for these codes as a technical 
correction.
    We reviewed the list of codes submitted by the RUC and we agree 
that there appears to be a technical error in the global period 
assignment for these codes. Most of the affected codes have non-payable 
status codes and no RVUs, while the handful of affected HCPCS codes 
that do have RVUs specifically state in their descriptors that they 
were intended to be add-on codes, such as CPT code 88332 (Pathology 
consultation during surgery; each additional tissue block with frozen 
section(s)). We therefore proposed to change the following codes to the 
ZZZ global period:

[[Page 71017]]

[GRAPHIC] [TIFF OMITTED] TR09NO26.075

    The RUC also requested assigning the ZZZ global period to three 
anesthesia codes: CPT codes 01953, 01968, and 01969. However, currently 
all anesthesia codes use the XXX global period, and it is unclear 
whether the concept of an add-on global period would apply to 
anesthesia coding given that they are valued using base units and time 
units, unlike all other PFS services. As noted in the proposed rule, we 
did not propose the ZZZ global period for these three codes at this 
time. We solicited comments from interested parties regarding the 
global period assignment for these three anesthesia codes, as well as 
the other codes listed in Table A-B7.
    We received public comments on these proposals. The following is a 
summary of the comments we received and our responses.
    Comment: Several commenters stated that they did not support 
assigning a ZZZ global period to CPT codes 01953, 01968, and 01969 and 
questioned the necessity and potential negative consequences of doing 
so. The commenters stated that although they understood the RUC's 
rationale for requesting a ZZZ global period assignment for CPT codes 
01953, 01968, and 01969, they believed this would be an inappropriate 
policy change that could have unintended negative consequences. The 
commenters stated that the anesthesia code set does not currently 
utilize global periods beyond the perceived global period defined by 
the anesthesia start and stop times of an anesthesia service and 
establishing any structure that would appear to assign an anesthesia 
global period could lay the groundwork to establishing a defined 
generic or average global period that could impact the unique 
recognition and utilization of an actual case's unique start and stop 
times. The commenters stated that the administrative burden of ensuring 
that these downstream impacts would not occur would far outweigh any 
perceived benefit of unnecessarily assigning a ZZZ global period to 
these codes.
    Response: We appreciate the feedback from the commenters; we agree 
that there are unique aspects to the anesthesia codes and therefore 
continue to believe that CPT codes 01953, 01968, and 01969 should 
retain the same XXX global period used by all other anesthesia codes.
    After consideration of public comments, we are finalizing the 
change to a ZZZ global period for the codes listed in Table A-B7 as 
proposed. We are not finalizing a change in the global period for 
anesthesia CPT codes 01953, 01968, and 01969.
    Comment: Several commenters, including the RUC, requested that CMS 
separately identify and pay for high-cost

[[Page 71018]]

disposable supplies. Commenters highlighted the outsized impact that 
high-cost disposable supplies have within the current practice expense 
RVU methodology, which not only accounts for a large amount of direct 
practice expense for these supplies but also allocates a large amount 
of indirect practice expense into the PE RVU for the procedure codes 
that include these supplies. Commenters stated that if high-cost 
supplies were paid separately with appropriate HCPCS codes, the 
disproportionate indirect expense would no longer be associated with 
that service, with the result that indirect PE RVUs would be 
redistributed throughout the specialty practice expense pool and the 
practice expense for all other services. Commenters requested that CMS 
separately identify and pay for high-cost disposable supplies priced 
more than $500 using appropriate HCPCS codes. Commenters stated that 
they had anticipated a response from CMS on this issue and argued that 
the pricing of these supplies should be based on a transparent process 
whereby items are reviewed and updated on an annual basis.
    Response: We have received a number of prior requests from 
interested parties, including the RUC, to implement these separately 
billable alpha-numeric Level II HCPCS codes to allow practitioners to 
be paid the cost of high cost disposable supplies per patient encounter 
instead of per CPT code. We stated at the time, and we continue to 
believe, that this option presents a series of potential problems that 
we have addressed previously in the context of the broader challenges 
regarding our ability to price high cost disposable supply items. We 
did not propose and are not finalizing the implementation of standalone 
Level II HCPCS codes for high cost disposable supplies at this time. 
For further discussion of this issue, we direct the reader to our 
discussion in the CY 2011 PFS final rule with comment period (75 FR 
73251).
    This is a subject that we may consider for future rulemaking 
alongside other updates to the PE methodology. We appreciate the 
continued feedback from commenters as we consider potential approaches 
to this complicated topic.
d. Updates to Practice Expense (PE) Methodology--Site of Service 
Payment Differential
    We proposed a significant refinement to our PE methodology to 
better reflect trends in physician practice settings in the CY 2026 PFS 
final rule (90 FR 49292 through 49297). Under the finalized policy, we 
allocate half the amount of indirect PE RVUs per work RVU for services 
furnished in the facility setting compared to those allocated to 
services furnished in the non-facility setting. We noted in the CY 2026 
PFS proposed rule (90 FR 32374) that this change to the indirect cost 
allocation methodology was intended to better recognize the relative 
resources involved in furnishing services paid under the PFS in 
facility and non-facility settings. We compared this change to our 
current methodology prior to CY 2026, which functionally presumed 
approximately equal indirect costs incurred by physicians across sites 
of service. This presumption was initially made in the context of most 
practitioners maintaining office practices independent of the 
facilities in which they provided care, and as we discussed in the CY 
2026 PFS proposed and final rules, appears to be inconsistent with 
contemporary trends in physician practice where some significant 
portion of services furnished in facility settings are performed by 
medical practitioners who do not maintain fully independent practices 
and are less likely to incur a comparable amount of indirect costs.
    Since finalizing the proposal in the CY 2026 PFS final rule, we 
have heard from interested parties that the implementation of this 
policy resulted in an unintended, but significant, site of service 
differential for physician visits in nursing facility settings based 
solely on whether the beneficiary's stay is covered under Part A. For 
purposes of PFS payment, a service furnished to a patient in a skilled 
nursing facility during a Part A hospital stay (place of service 31) is 
considered to be in the ``facility'' setting, while a service furnished 
to a patient in a Part B stay (place of service 32) is considered to be 
in the ``non-facility'' setting, per the Medicare Claims Processing 
Manual (MCPM), Chapter 12, Section 20.4.2 at <a href="http://www.cms.gov/Regulations-and-Guidance/Guidance/Manuals/Downloads/clm104c12.pdf">http://www.cms.gov/Regulations-and-Guidance/Guidance/Manuals/Downloads/clm104c12.pdf</a>. 
Prior to CY 2026, the payment rate for these E/M services furnished in 
a skilled nursing facility (``facility'') and a nursing facility 
(``non-facility'') were equal. As intended, the 50 percent reduction to 
the allocation of indirect PE based on work RVUs that we finalized for 
CY 2026 shifted PE RVUs from the facility setting to the non-facility 
setting. However, for nursing facility and skilled nursing facility 
visits, the current site of service differential is determined based on 
the status of the beneficiary (that is, a Part A versus Part B stay) in 
that setting, rather than in the setting of care itself. Given that the 
resource costs for the professional involved in furnishing an E/M 
service would not be expected to differ based on whether the patient is 
in a Part A stay or not, we believe it is more accurate for these E/M 
services to be paid the same amount without regard to the beneficiary's 
Part A status.
    Therefore, we proposed to address this anomaly for CY 2027 by 
equalizing the rate for nursing facility visits without regard to the 
beneficiary's status by setting the facility PE RVU equal to the non-
facility PE RVU for CPT codes 99304 (Initial nursing facility care, per 
day, for the evaluation and management of a patient, which requires a 
medically appropriate history and/or examination and straightforward or 
low level of medical decision making. When using total time on the date 
of the encounter for code selection, 25 minutes must be met or 
exceeded.), 99305 (Initial nursing facility care, per day, for the 
evaluation and management of a patient, which requires a medically 
appropriate history and/or examination and moderate level of medical 
decision making. When using total time on the date of the encounter for 
code selection, 35 minutes must be met or exceeded.), 99306 (Initial 
nursing facility care, per day, for the evaluation and management of a 
patient, which requires a medically appropriate history and/or 
examination and high level of medical decision making. When using total 
time on the date of the encounter for code selection, 50 minutes must 
be met or exceeded.), 99307 (Subsequent nursing facility care, per day, 
for the evaluation and management of a patient, which requires a 
medically appropriate history and/or examination and straightforward 
medical decision making. When using total time on the date of the 
encounter for code selection, 10 minutes must be met or exceeded.), 
99308 (Subsequent nursing facility care, per day, for the evaluation 
and management of a patient, which requires a medically appropriate 
history and/or examination and low level of medical decision making. 
When using total time on the date of the encounter for code selection, 
20 minutes must be met or exceeded.), 99309 (Subsequent nursing 
facility care, per day, for the evaluation and management of a patient, 
which requires a medically appropriate history and/or examination and 
moderate level of medical decision making. When using total time on the 
date of the encounter for code selection, 30 minutes must be met or 
exceeded.), 99310 (Subsequent nursing facility care, per day, for the 
evaluation and management of a patient, which requires a medically 
appropriate history and/or examination and high level of medical 
decision

[[Page 71019]]

making. When using total time on the date of the encounter for code 
selection, 45 minutes must be met or exceeded.), 99315 (Nursing 
facility discharge management; 30 minutes or less total time on the 
date of the encounter), and 99316 (Nursing facility discharge 
management; more than 30 minutes total time on the date of the 
encounter).
    This particular situation illuminates ongoing concerns regarding 
the current site of service differential. For example, interested 
parties have suggested that the current binary of facility and non-
facility does not account for the range of employment models associated 
with physician services that drive significant differences in actual 
practice expenses. Interested parties have encouraged us to refine our 
previously finalized policy to ensure it is more empirically grounded 
and narrowly tailored to independent physicians, consistent with the 
policy's original intent. Interested parties have also stated that the 
facility PE reductions have had a disparate effect on hospital medicine 
groups and hospitalists, particularly those that operate independently 
from their hospital or health systems. Interested parties have stated 
that independent hospital medicine groups account for approximately 
one-third to one-half of the hospital medicine groups nationwide, and 
they are unable to cut administrative and overhead costs enough to 
absorb our CY 2026 facility PE reductions. As a result, some interested 
parties have stated that the reductions are accelerating the insolvency 
of independent physician practices and leading to an increase in 
hospital consolidation. We note that we have heard no general consensus 
among interested parties to this effect, and we have received feedback 
that this policy supports independent practices.
    In the CY 2026 PFS proposed rule, we sought comments on whether our 
proposal to reduce the portion of the facility PE RVUs allocated based 
on work RVUs to half the amount allocated to non-facility PE RVUs was 
an appropriate reduction or whether we should consider a different 
percentage reduction for CY 2026 or in future years. In finalizing the 
proposal, we noted that, while our change to the methodology for CY 
2026 represented a starting point to correcting historic distortions in 
the allocation of indirect PE costs across settings of care, we 
intended to further examine our methodology and consider additional 
refinements based upon feedback received and any studies or data 
sources identified.
    For CY 2027, we remained open to more specific data that addresses 
the variability, as well as feedback on how to update the valuation and 
payment methodologies to better reflect the relative resources involved 
in furnishing the services, both across settings of care, and within 
the context of an evolving ecosystem of care models and business 
arrangements. Historically, we have relied extensively on specialty-
specific PE/HR survey data and the binary site of service differential 
to best reflect variable PE costs.
    To better inform our consideration of how to account for practice 
expenses under the PFS methodologies, including the current 
differentials that are effectuated based on the binary facility/non-
facility settings of care, we sought comment on how PE costs vary for 
physicians and other professionals, not only based on whether they 
practice in part or exclusively in a facility setting but also based on 
how their costs vary when they are employed by health systems, 
hospitals, or other entities. We noted in the CY 2026 PFS final rule 
that (90 FR 49292) that the AMA has stated that physician practices 
maintain some indirect PE costs for physicians who are solely facility-
based such as coding, billing, and scheduling. That being said, we 
generally agree with the concerns presented by MedPAC on the growth of 
exclusively facility-based physicians and agree that potential 
overpayments for indirect practice expense costs could be a driver of 
clinician movement to higher cost settings without creating 
commensurate clinical value. This is why we lowered indirect PE for 
facility-based physician to 50 percent in the CY 2026 PFS final rule.
    Moving forward, we remain interested in ensuring indirect PE RVUs 
are appropriately accounting for indirect PE costs. As such, we sought 
information that will help illuminate to what extent these costs are 
truly incurred when the professionals are employed by the hospital and/
or practice primarily in the hospital and are not already accounted for 
in the existing OPPS payments. For example, when a physician is 
employed by and practicing in a hospital, what portion of the indirect 
PE is associated with the PFS service, versus costs that are associated 
with the payment to the hospital, such as those paid under the OPPS?
    We sought comment on the amount of indirect PE hospital-employed 
physicians incur when they furnish care within a facility. For these 
physicians, is the 50 percent indirect PE allocation accurate or could 
it possibly be less than 50 percent, such as 0 percent? In the case 
that there are little to no indirect costs incurred by the physician or 
other professionals, and these costs are borne by the hospital, we 
believe that these costs are not appropriately accounted for under the 
PFS and we may well be overestimating the relative resource costs 
compared to other PFS services. In consideration of the accuracy of the 
current 50 percent indirect PE allocation for services furnished in the 
facility setting, we are also seeking comment on whether and how we 
might, alternatively or additionally, define and identify physicians 
and professionals who are employed by hospitals, health systems, or 
other entities to ensure the services they furnish are not 
inappropriately consuming PE RVUs that would be more appropriately 
assigned to services furnished by professionals incurring comparatively 
greater practice expenses. Specifically, we sought comment on whether a 
new HCPCS modifier for employed physicians would be a reasonable way to 
identify and reduce facility PE from the services they perform in the 
facility setting, or whether there are other methods we could consider.
    We sought comment on what are the primary variables we should 
consider to continue to improve our data sources, allocation 
methodologies, and payment rates across settings of care, to best 
reflect the resources involved in furnishing PFS services by 
professionals and suppliers operating in a complex marketplace, across 
settings of care. We remain interested in objective data regarding 
payment arrangements between hospitals, health systems, other employers 
and physicians, including which costs are incurred and whether the full 
range of costs are truly incurred by physicians and other professionals 
in these kinds of employment relationships. This would help us 
understand and improve how PE is allocated across settings of care, 
both in general and for specific kinds of services.
    We received public comments on this proposal and comment 
solicitation. The following is a summary of the comments we received 
and our responses.
    Comment: Commenters were unanimously supportive of our proposal to 
set the facility PE RVU equal to the non-facility PE RVU for nursing 
facility E/M codes (CPT codes 99304 through 99310, 99315 and 99316). We 
also received feedback in response to our comment solicitation on the 
current site of service differential finalized in the CY 2026 PFS final 
rule.
    Response: We appreciate the commenters' support on our proposal. We 
received many comments on our comment solicitation regarding the site 
of service differential. Commenters agreed that using facility place-
of-

[[Page 71020]]

service as a proxy for physician employment is imprecise, though they 
were divided on how to structure the differential going forward, with 
some supporting refinements such as additional specialty-specific 
adjustments and more detailed impact data. Most recommended replacing 
or supplementing this proxy with a more direct method of identifying 
hospital-employed physicians, with several suggesting independent 
practices self-identify given their incentive to do so. However, many 
commenters cautioned that employment status alone is not a reliable 
indicator of who bears indirect costs, noting that practices often 
continue to incur substantial administrative costs regardless of 
employment or site of service, and that the variety of employment 
arrangements makes any binary classification difficult to administer 
and prone to disputes. Commenters broadly urged CMS to take a more 
data-driven approach, including easing the impact on independent 
practices and reconsidering the reduction until better evidence is 
available. They also raised specialty-specific concerns and warned the 
policy could accelerate practice consolidation into hospital employment 
or acquisition by other entities. After consideration of public 
comments, we are finalizing to set the facility PE RVU equal to the 
non-facility PE RVU for nursing facility E/M codes (CPT codes 99304 
through 99310, 99315 and 99316), as proposed. We may consider comments 
about the site-of-service differential in future rulemaking.
6. Strategies To Improve Payment Transparency, Accuracy, and Congruency 
Across Payment Systems
a. Professional and Technical Components
    Because PFS services are paid across settings of care, and are the 
primary way that Medicare pays medical professionals, understanding the 
structure of PFS payment is a critical part of price transparency for 
Medicare, other payers, and consumers. Likewise, misunderstanding or 
confusion about what relative resources are incorporated in specific 
PFS payment rates can be a significant obstacle for payers and 
consumers navigating the health care market. For example, approximately 
4,100 services paid as ``global surgical packages,'' (herein `globals') 
are valued as bundled payments that aggregate multiple components of 
care into a single payment amount, including post-operative visits that 
are presumed to occur in particular settings (for example, inpatient 
hospital, outpatient hospital, office) regardless of where the services 
actually take place. Most PFS services are valued with a site of 
service binary, where the non-facility setting is the aggregation of 
all relative resources involved in furnishing the professional and 
technical aspects of the service, and the facility setting, where the 
rate generally excludes the facility costs involved in the service 
since those costs are addressed through separately reported facility 
fees. In contrast to these two constructs, there are other codes 
(mainly describing diagnostic and imaging services) that may be billed 
with professional component (PC, or modifier 26) and technical 
component (TC) modifiers, or without modifiers (global codes) that are 
paid for the complete global service. These differences in how payments 
are constructed and displayed can make it difficult for interested 
parties and CMS to evaluate relative payment rates, underlying resource 
costs, and value across settings of care.
    These challenges are further compounded by differences across 
Medicare payment systems in how similar services are defined, bundled, 
and paid. For example, some payment systems incorporate technical 
inputs and facility resources into a single payment. This variation can 
obscure meaningful comparisons across sites of care and may complicate 
efforts to advance site-neutral payment policies aimed at reducing 
incentives for hospitals to acquire physician practices and limit site-
of-care decisions based on financial considerations. As CMS continues 
to consider approaches that remove obstacles from market competition 
across settings of care, especially by improving transparency, 
comparability of PFS payments is an important foundational step.
    We noted in the proposed rule, to facilitate more consistent 
comparisons across services and settings, we have developed a public 
use file that displays, for services that are not currently billable 
with TC/26 modifiers, RVUs amounts that reflect the relative resources 
involved in furnishing professional and technical aspects of the 
services, which is available on the CMS website under downloads for the 
CY 2027 PFS proposed rule at <a href="https://www.cms.gov/medicare/payment/fee-schedules/physician/federal-regulation-notices">https://www.cms.gov/medicare/payment/fee-schedules/physician/federal-regulation-notices</a>. This file is intended 
to improve transparency regarding how PFS payments may be conceptually 
divided between physician professional and technical components of the 
services, especially to illuminate the differences in fees between 
technical aspects of PFS services compared to facility fees across 
settings of care. We believe that making these components more visible, 
where feasible, may help interested parties better understand the 
structure of PFS payments and support more informed comparisons across 
settings of care. We noted that we have excluded 10- and 90-day global 
surgery services from display in this public use file since there are 
numerous ways to consider how the structure of payment for those codes 
may be best understood. The use of bundled payments for the 10- and 90-
day global surgery services results in aggregated valuation for all 
pre-operative, intra-operative, and post-operative services furnished 
over a defined period (0-, 10-, or 90-day global periods), including 
services by both physician and clinical staff and practice expense 
without clear visibility into how each component contributes to the 
total bundled valuation. While we noted that the current structure of 
global surgery services has effectively obscured how the components of 
care are individually valued and limited our ability to disaggregate 
them for purposes of this public use file, we sought comment on how to 
address this problem, either in possible improvements to the global 
surgery packages or, at least, in the best way to make their component 
pieces transparent.
    Additionally, we noted that there is a subset of additional 
exclusions from this public use file, such as codes subject to the 
cognitive services floor and the statutory phase-in of significant RVU 
reductions, due to technical challenges with how these policies are 
implemented that hinder the disaggregation of their component parts.
    We emphasized in the proposed rule that we did not propose any 
changes to existing payment or billing policies, including the use of 
the 10- and 90-day globals. Rather, this effort is intended to improve 
transparency and provide a foundation for future rulemaking. We believe 
that greater visibility into how the professional and technical aspects 
of PFS services are valued and paid, where feasible, may enhance the 
ability of consumers, and payers (including CMS) to assess relativity 
across services, may enhance CMS's efforts to improve valuation over 
time, and support broader efforts to align payments across settings of 
care. We sought comment on several aspects of this approach. First, we 
sought comment on the utility of displaying RVUs associated with 
professional and technical aspects of services that are not currently 
billable with TC/26 modifiers, including how we may use this 
information to assess payment differences across settings. Again, we 
also sought comment on

[[Page 71021]]

potential approaches CMS could consider in future rulemaking to improve 
transparency for services currently paid as globals. Specifically, we 
were interested in feedback on how CMS could develop methodologies to 
more clearly identify and, where appropriate, disaggregate the 
underlying components of these services. We were also interested in 
comments on how CMS could ``right-size'' payments for the globals over 
time to ensure they remain aligned with current clinical practice and 
resource costs, are more readily updated based on empirical data, and 
do not obscure differences in cost and value across settings of care.
    We received public comments on this comment solicitation. The 
following is a summary of the comments we received and our responses.
    Comment: Some commenters were supportive of the CMS goal of 
improving transparency and developing more consistent information about 
the resources used to furnish services across different settings, but 
disagreed with our methodology of developing component-level values for 
services that the commenters say were not designed or valued as 
separately billable professional and technical components. Commenters 
stated that the display-only file raises significant methodological and 
policy questions, and that these values should not be treated as 
directly comparable, or used to support future payment changes, until 
CMS has completed further analysis and engaged affected interested 
parties. Another commenter stated that the proposed approach to create 
the file appears to be arbitrary and does not reflect allocations based 
on a thorough review of each service, and discouraged us from advancing 
future payment policy that relies on the public use file. The commenter 
stated that there are often justifiable reasons for cost variation 
between different sites of care and expressed concern that we intend to 
use the file in future years to equalize rates across sites of care 
that could result in hospitals being underpaid for care.
    Response: We appreciate the commenters' support of our efforts to 
make available transparent information about the resources required to 
furnish services across settings. With respect to commenters who stated 
that the file's methodology was arbitrary or lacked utility, we note 
that estimating component-level resource use for display purposes does 
not require that those components be separately billable, and we 
believe such estimates can serve the transparency goals described in 
the proposed rule. We are open to alternative approaches to advancing 
comparisons across sites of care and may take any such suggestions into 
account in future rulemaking. We did not propose to use the file for 
payment comparisons in this rule. The display is intended only to begin 
building a transparency foundation, as described in the comment 
solicitation. We will consider commenters' methodological concerns 
before any future proposal that relies on cross-setting comparisons.
    Comment: Some commenters stated that the re-presentation is more 
understandable to interested parties, but it would be more useful if 
CMS confirmed the systemic approach used or explained in greater detail 
how CMS developed the resource with sample calculations. Another 
commenter stated that they strongly support the establishment of this 
public use file because the AMA has historically been the gatekeeper of 
the relevant information utilized when determining RVU amounts. The 
commenter stated that the process is secretive and monetized access to 
databases has prevented interested parties from accessing and 
understanding the structure of PFS payments. Another commenter 
requested the addition of the code descriptors to the file to improve 
the readability and data analytics of the public use file.
    Response: We appreciate the feedback from interested parties and 
may consider expanding the scope of the file in future rulemaking.
    Comment: A commenter suggested that this file allows the 
opportunity for TC services under the MPFS to use the OPPS relativity 
data (excluding the packaged services) to assess the PE RVUs, rather 
than survey data. The commenter said that this would be similar to what 
CMS proposed for radiation oncology and proton beam treatment delivery 
services. They stated that they believe the public use file would 
provide greater accuracy to tie the RVUs to the audited hospital cost 
report data for the PE component, rather than survey data. The 
commenter also requested that we consider publishing the direct and 
indirect PE RVUs for facility and non-facility for all codes, and 
stated that this information available across services would provide 
valuable information and would increase transparency associated with 
RVUs and the PFS.
    Response: We appreciate the feedback from interested parties. We 
may consider publishing the direct and indirect PE RVUs in future 
rulemaking.
b. Global Surgical Packages
    We finalized a policy in the CY 2015 PFS final rule (79 FR 67582 
through 67591) to transition all 10-day and 90-day globals to 0-day 
globals, allowing any post-operative visits furnished after the day of 
the procedure to be billed as a standalone visit. CMS was prohibited 
from implementing this policy through section 523(a) of the Medicare 
Access and CHIP Reauthorization Act (MACRA) and was required to collect 
data on how to best value globals. CMS did so through a research 
contract with RAND and a data-collection process over several years to 
develop data to improve the payment rates for these services. Data 
collection has been based on reporting of CPT code 99024 (Postoperative 
follow-up visit, normally included in the surgical package, to indicate 
that an evaluation and management service was performed during a 
postoperative period for a reason(s) related to the original 
procedure), which is limited to practices with 10 practitioners or 
more, limited to nine States, and is used solely for data collection so 
it has no associated payment with reporting the code. In the CY 2019 
PFS final rule (83 FR 59503), we released findings that only 4 percent 
of reviewed 10-day globals and 67 percent of reviewed 90-day globals 
had one or more post-operative visit which occurred during the global 
period and sought comment on potential approaches for revaluing the 
globals based on these findings (83 FR 59504). In the CY 2023 PFS 
proposed rule (87 FR 45877 through 45880), CMS reviewed the prior work 
and conversations around global valuations, solicited feedback from the 
public, and has continued to explore ways over the years to address 
valuation of the globals that would be minimally disruptive to the PFS.
    Over the past several years, CMS has taken several iterative steps 
to improve payment accuracy for the globals. In the CY 2025 PFS final 
rule (89 FR 97964 through 97968), CMS expanded the applicability of the 
transfer of care modifiers to address instances where separate 
practitioners are billing for standalone E/M visits during the global 
period more directly with mandatory reporting of payment modifiers in 
clinical cases when there is both a formal or informal transfer of care 
between practitioners furnishing distinct portions of a global service. 
CMS also created a post-operative care services add-on code to more 
appropriately reflect the time and resources involved for practitioners 
who were not involved in furnishing the surgical procedure. CMS is 
continuing to explore further steps to improve accountability and more 
accurate

[[Page 71022]]

payment and what additional next steps CMS could take to improve the 
payment rates for global services.
    In keeping with the administration priorities and aligning spending 
and value, we proposed to pause the data collection required by MACRA 
based on RAND's findings over the past several years. We remain 
interested in how best to use and collect this data going forward and 
ways we might consider improving this data collection. We currently 
have several years of data that have continued to illustrate what we 
believe is the issue with the post-operative visits during the global 
period and how these visits are not occurring, yet providers are still 
being paid for these visits under the current global payment policy. 
Additionally, we believe that the current data collection may be 
causing undo burden to providers and we believe that pausing the data 
collection will aid in burden reduction for practitioners. We do 
however question whether a more robust data collection would be 
appropriate and if we should have all providers report CPT code 99024.
    We also sought comment on the question, as to whether CMS should 
have all providers report CPT code 99024, and also other data sources 
we might consider to more accurately value the globals.
    We received public comments on these proposals. The following is a 
summary of the comments we received and our responses.
    Comment: Commenters were generally in support of the CMS proposal 
to pause the data collection required by MACRA to report CPT code 
99024. Most commenters were not in support of CMS using that data for 
the revaluation process. Commenters were overall in agreement that 
expanding the data collection would pose undo administrative burden to 
providers and urged CMS to not expand the reporting. Commenters were 
not in support of using the information presented in the Public Use 
File (PUF), in particular the purely ``arithmetic approach'' to 
understand the valuation of the services based on the data that was 
analyzed. Many commenters were opposed to CMS using the reported data 
in the process of revaluation. Commenters stated that the 
underreporting of CPT code 99024 does not indicate or capture the post-
operative work that was furnished even though a visit was not actually 
reported. Commenters noted that pausing the data collection allows for 
opportunity to evaluate the data limitations and develop a more 
accurate approach. Several commenters suggested CMS spend time 
understanding post operative care, how it is organized, as well as non-
visit post-operative work that takes place even when a visit is not 
furnished as care extends beyond the post-operative visits.
    Response: We appreciate the commenters' feedback and support of 
pausing the data collection of CPT code 99024. We understand the 
commenters' concerns that data collection may impose administrative 
burden and understand this concern with expanding the data collection 
beyond the sample that was required. We believe that a pause in the 
data collection allows CMS an opportunity to evaluate the data 
limitations and further refine our approach to data collection on the 
global surgical packages.
    After consideration of public comments on our proposal, we are 
finalizing pausing the data collection as proposed. CMS remains 
interested in how to best capture post operative data to better inform 
valuation of post-operative services under the PFS.
    As noted in the proposed rule, we posted a public use file with the 
proposed rule to display the imputed RVUs associated with both the 10- 
and 90-day post-operative visits based on a purely arithmetic approach 
to understand the valuation of the services based on the data that was 
analyzed. The public use file shows the current work RVUs, the number 
of post-operative visits that are reported to CMS using no-pay HCPCS 
code 99024, and the work RVUs remaining if all post-operative visits 
are removed. The public use file is available on the CMS website under 
downloads for the CY 2027 PFS final rule at <a href="https://www.cms.gov/medicare/payment/fee-schedules/physician/federal-regulation-notices">https://www.cms.gov/medicare/payment/fee-schedules/physician/federal-regulation-notices</a>. We 
solicited comments on potential revaluation strategies that we may 
consider through future rulemaking. We received public comments on 
these proposals. The following is a summary of the comments we received 
and our responses.
    Comment: As stated previously, many commenters were not in support 
of using the information in the public use file to help inform 
revaluation of the global surgical packages. Other commenters thought 
it was a good first step toward the revaluation process. A few 
commenters supported aligning payment for global surgical services with 
services actually furnished, while others noted the reporting of CPT 
code 99024 did not specify the visit level or level of physician work. 
Other commenters supported the publication of the imputed post-
operative visit RVU public use file while other commenters did not 
think CMS should use missing postoperative visit claims as proof that 
postoperative care is not being furnished.
    Response: We thank the commenters for their feedback.
    After consideration of public comments, we express appreciation for 
the feedback from commenters and will take the comments into 
consideration for possible future rulemaking.

C. Payment for Medicare Telehealth Services

    As discussed in prior rulemaking, several conditions must be met 
for Medicare to make payment for telehealth services under the PFS. See 
further details and full discussion of the scope of Medicare telehealth 
services in the CY 2018 PFS final rule (82 FR 53006), the CY 2021 PFS 
final rule (85 FR 84502), the CY 2024 PFS final rule (88 FR 78861 
through 78866), the CY 2026 PFS final rule (90 FR 49316 through 49320), 
and in 42 CFR 410.78 and 414.65. Our current 3-step review process 
reflects the stepwise method by which we consider requests to add 
services to or remove services from the Medicare Telehealth Services 
List, beginning with the CY 2026 Medicare Telehealth Services List:
    Step 1. Determine whether the service is separately payable under 
the PFS.
    Step 2. Determine whether the service is subject to the provisions 
of section 1834(m) of the Act.
    Step 3. Review the elements of the service as described by the 
HCPCS code and determine whether each of them is capable of being 
furnished using an interactive telecommunications system as defined in 
Sec.  410.78(a)(3).
1. Changes to the Medicare Telehealth Services List
a. Requests To Add Services to the Medicare Telehealth Services List 
for CY 2027
    We did not receive any requests to add or remove services from the 
Medicare Telehealth Services List for CY 2027.
    Consistent with the deadline for our receipt of code valuation 
recommendations from the American Medical Association's Relative Value 
Scale Update Committee (AMA RUC) and other interested parties 
established in the CY 2019 PFS final rule (83 FR 59491) and with the 
process set forth in prior calendar years, for CY 2027, requests to add 
services to the Medicare Telehealth Services List must have been 
submitted to and received by CMS by February 10, 2026. Consistent with 
the deadline for our receipt of code

[[Page 71023]]

valuation recommendations from the AMA RUC and other interested parties 
established in the CY 2019 PFS final rule (83 FR 59491) and with the 
process set forth in prior calendar years, for CY 2028, requests to add 
services to the Medicare Telehealth Services List must be submitted to 
and received by CMS by February 10, 2027. Each request submitted by the 
deadline to add a service to the Medicare Telehealth Services List must 
include any supporting documentation the requester wishes CMS to 
consider. Because we use the annual PFS rulemaking process to make 
changes to the Medicare Telehealth Services List, requesters are 
advised that any information submitted as part of a request is subject 
to public disclosure for this purpose. For more information on 
submitting a request to add services to the Medicare Telehealth 
Services List, including where to send these requests, and to view the 
current Medicare Telehealth Service List, see our website at <a href="https://www.cms.gov/Medicare/Medicare-General-Information/Telehealth/index.html">https://www.cms.gov/Medicare/Medicare-General-Information/Telehealth/index.html</a>.
    We did not receive any requests to add or remove services from the 
Medicare Telehealth Services List for CY 2027 by the February 10, 2026 
deadline. However we received public comments on this topic from 
interested parties. The following is a summary of the comments we 
received and our responses.
    Comment: We received comments requesting services to be added to 
the Medicare Telehealth Services List during the public comment period 
for the CY 2027 proposed rule.
    Response: For consideration in the CY 2027 PFS rulemaking, requests 
to add services to the Medicare Telehealth Services List for CY 2027 
must have been received by February 10, 2026. For CY 2028, requests to 
add services to the Medicare Telehealth Services List must be submitted 
to and received by CMS by February 10, 2027.
    Comment: Commenters highlighted that we did not align certain 
services on the Medicare Telehealth List with services being deleted 
for CY 2027. As discussed in section II.D under Adaptive Behavior 
Services, at the September 2025 CPT Editorial Panel meeting, the CPT 
Editorial Panel deleted CPT codes 0362T and 0373T. These codes are 
being replaced with CPT codes 97148, 97149, 97159, 97160, and 97173. As 
discussed in section II.D. under Speech-Language Pathology Services, at 
the September 2025 CPT Editorial Panel meeting, CPT code 92507 was 
replaced with 10 new codes (92654, 92655, 92656, 92657, 92658, 92659, 
92660, 92661, 92662, and 92663).
    Response: We thank commenters for this information. We 
inadvertently maintained these codes on the Medicare Telehealth 
Services List. We believe that these codes represent replacements for 
the codes currently describing these services on the Medicare 
Telehealth Services List. As such, we are finalizing the deletion of 
CPT codes 92507, 0362T, and 0373T and the addition of CPT codes 97148, 
97149, 97159, 97160, 97173, 92654, 92655, 92656, 92657, 92658, 92659, 
92660, 92661, 92662, and 92663 to the Medicare Telehealth Services 
List.
    In accordance with our longstanding policy, requests to add 
services to the Medicare Telehealth Services List must be submitted to 
and received by CMS by February 10, 2026. We will not consider requests 
to add services submitted during the public comment period for the CY 
2027 proposed rule. That said, CPT codes 92507, 0362T, and 0373T will 
be removed from the Medicare Telehealth Service List as they were 
inadvertently maintained. We will be replacing deleted CPT code 92507 
with CPT codes 92654, 92655, 92656, 92657, 92658, 92659, 92660, 92661, 
92662, and 92663. We will be replacing deleted CPT codes 0362T and 
0373T with 97148, 97149, 97159, 97160, and 97173.
b. CMS Requirement To Add New Codes to the List
    In the CY 2027 PFS proposed rule, we proposed to add HCPCS G-codes 
G0572 (Advance care planning including the explanation and discussion 
of advance directives such as standard forms (with completion of such 
forms, when performed), first 20 minutes of clinical staff time with 
the patient, family member(s), directed by a treating physician or 
other treating qualified health care professional), G0573 (Advance care 
planning including the explanation and discussion of advance directives 
such as standard forms (with completion of such forms, when performed), 
each additional 20 minutes with the patient, family member(s), directed 
by a treating physician or other treating qualified health care 
professional (List separately in addition to code for primary 
procedure)), G0686 (Voluntary, group-based medical session involving 
multiple patients with common medical condition(s), receiving medical 
care in a group setting; billed and led by a physician or qualified 
nonphysician practitioner and may include services provided by other 
qualified healthcare professionals, clinical staff, or auxiliary 
personnel under the direction of the supervising physician or other 
practitioner. Session integrates group education, counseling, and peer 
support with individualized patient clinical assessment and care, 2-10 
patients, billed once per patient, per
