I. Executive Summary

A. Purpose

    This major annual rule proposes to revise payment policies under 
the Medicare PFS and makes other policy changes, including proposals to 
implement 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 16, 2023), Consolidated Appropriations Act, 2023 (Pub. 
L. 117-328, September 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) 
and 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), related to Medicare Part B payment. In 
addition, this proposed rule includes proposals regarding other 
Medicare payment policies described in sections III. and IV.
    This rulemaking proposes to update policies for the Medicare 
Prescription Drug Inflation Rebate Program codified or finalized at 
parts 427 and 428 consistent with sections 1847A(i) and 1860D-14B of 
the Social Security Act (the Act). With respect to the Medicare Part B 
Drug Inflation Rebate Program, this rulemaking proposes to describe the 
identification of payment amount benchmark quarter in certain instances 
and the calculation for the Part B rebate amount in such instances. 
With respect to the Medicare Part D Drug Inflation Rebate Program, this 
rulemaking proposes to clarify the calculation of a Part D rebate 
amount, and proposes a methodology for removal of units for a Part D 
rebatable drug for which a manufacturer provides a discount under the 
340B Program, as well as the establishment of a 340B data repository 
for Part D claims.
    This rulemaking proposes to modify policies for the Shared Savings 
Program, which is a voluntary program that started in 2012. The program 
allows healthcare providers to form or participate in Accountable Care 
Organizations (ACOs), 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 proposed rule, we are proposing to establish RVUs for 
CY 2026 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 proposed rule also includes 
discussions and provisions regarding several other Medicare Part B 
payment policies, and other policies regarding programs administered by 
CMS.
    Specifically, this proposed rule addresses:
    <bullet> Background (section II.A.)
    <bullet> Determination of PE RVUs (section II.B.)
    <bullet> Potentially Misvalued Services Under the PFS (section

    <bullet> Enhanced Care Management (section II.G.)
    <bullet> Outpatient Therapy Services and KX Modifier Thresholds 
(section II.H.)
    <bullet> Advancing Access to Behavioral Health Services (section

    <bullet> Provisions on Medicare Parts A and B Payment for Dental

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 
proposed 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 will be two separate conversion factors (CFs): 
one for items and services furnished by a qualifying APM participant as 
defined in section 1833(z)(2) of the Act (referred to as the qualifying 
APM conversion factor) and another for other items and services 
(referred to as the nonqualifying APM conversion factor), equal to the 
respective conversion factor for the previous year (or, for CY 2026, 
equal to the single conversion factor for CY 2025) multiplied by the 
update established under section 1848(d)(20) of the Act for such 
respective conversion factor for such year. Under these proposals, the 
2026 qualifying APM conversion factor represents a projected increase 
of $0.39 (1.2 percent) from the current conversion factor of $32.3465. 
Similarly, the 2026 nonqualifying APM conversion factor represents a 
projected increase of $0.23 (0.7 percent) from the current conversion 
factor of $32.3465.
    For a detailed discussion of the economic impacts, see section 
VII., Regulatory Impact Analysis, of this proposed rule.

II. Provisions of the Proposed 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 proposed 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 referred readers to the 5-year review of work RVUs under the PFS and 
proposed 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 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 is developed based entirely on 
the PPIS data, except as noted in this section.

[[Page 32355]]

    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 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 2026 PFS proposed rule PE/HR'' on the 
CMS website under downloads for the CY 2026 PFS proposed rule at 
<a href="https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/PhysicianFeeSched/PFS-Federal-Regulation-Notices.html">https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/PhysicianFeeSched/PFS-Federal-Regulation-Notices.html</a>.
    For CY 2026, we have incorporated the available utilization data 
for one new specialty, Epileptologists, which we recognized effective 
July 1, 2024 through our established process. We are proposing to use 
proxy PE/HR values from Neurology for this new specialty, as there are 
no PPIS data for this specialty.
    These updates are reflected in the ``CY 2026 PFS proposed rule PE/
HR'' file available on the CMS website under the supporting data files 
for the CY 2026 PFS proposed rule at <a href="https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/PhysicianFeeSched/PFS-Federal-Regulation-Notices.html">https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/PhysicianFeeSched/PFS-Federal-Regulation-Notices.html</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
    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, 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.
(3) Facility and Nonfacility 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 nonfacility. The methodology for calculating PE 
RVUs is generally the same for both the facility and nonfacility 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 nonfacility PE RVUs. We note, too, that in 
this proposed rule we are proposing a modification in the allocation of 
indirect PE, described in detail below.
(4) Services With Technical Components and Professional Components
    Diagnostic services are generally comprised of two components: a

[[Page 32356]]

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.)
(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 2026 PFS 
proposed rule at <a href="https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/PhysicianFeeSched/PFS-Federal-Regulation-Notices.html">https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/PhysicianFeeSched/PFS-Federal-Regulation-Notices.html</a>. This 
file contains a table that illustrates the calculation of PE RVUs as 
described in this proposed 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/nonfacility 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 three 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 
59283) 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.
    The full list of expected specialty assignments is included in the 
CY 2026 public use files, which are available on the CMS website under 
downloads for the CY 2026 PFS proposed rule at <a href="http://www.cms.gov/Medicare/Medicare-Fee-for-ServicePayment/PhysicianFeeSched/PFS-Federal-Regulation-Notices.html">http://www.cms.gov/Medicare/Medicare-Fee-for-ServicePayment/PhysicianFeeSched/PFS-Federal-Regulation-Notices.html</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.
    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: 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> 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 are proposing a change to the 
methodology so that when work RVUs are used to

[[Page 32357]]

allocate indirect PE to the facility RVUs, they are assigned at one-
half the amount allocated to the nonfacility PE RVUs for that same 
service. This proposed change is detailed later in this section.
    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.
    Calculate the indirect practice cost index.
    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.
(d) Calculate the Final PE RVUs
    Step 18: 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 proposed rule.)
    Step 19: 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 shall 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 one 
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).
(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 1.
BILLING CODE 4120-01-P

[[Page 32358]]

[GRAPHIC] [TIFF OMITTED] TP16JY25.005

BILLING CODE 4120-01-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 TC and 26 modifiers: Flag the services that 
are PC and TC services but do not use TC and 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: Payment modifiers are accounted for in 
creating the file consistent with the current payment policy as 
implemented in claims processing. For example, services billed with the 
assistant at surgery modifier are paid 16 percent of the PFS amount for 
that service; therefore, the utilization file is modified to only 
account for 16 percent of any service that contains the assistant at 
surgery modifier. Similarly, for those services to which volume 
adjustments are made to account for the payment modifiers, time

[[Page 32359]]

adjustments are applied as well. For time adjustments to surgical 
services, the intraoperative portion in the work time file is used; 
where it is not present, the intraoperative percentage from the payment 
files used by contractors to process Medicare claims is used instead. 
Where neither is available, we use the payment adjustment ratio to 
adjust the time accordingly. Table 2 provides details in which the 
modifiers are applied.
[GRAPHIC] [TIFF OMITTED] TP16JY25.006

    We also adjust volume and time that correspond to other payment 
rules, including special multiple procedure endoscopy rules and 
multiple procedure payment reductions (MPPRs). We note that section 
1848(c)(2)(B)(v) of the Act exempts certain reduced payments for 
multiple imaging procedures and multiple therapy services from the BN 
calculation under section 1848(c)(2)(B)(ii)(II) of the Act. These MPPRs 
are not included in the development of the RVUs.
    Beginning in CY 2022, section 1834(v)(1) of the Act required that 
we apply a 15 percent payment reduction for outpatient occupational 
therapy services and outpatient physical therapy services that are 
provided, in whole or in part, by a physical therapist assistant (PTA) 
or occupational therapy assistant (OTA). Section 1834(v)(2)(A) of the 
Act required CMS to establish modifiers to identify these services, 
which we did in the CY 2019 PFS final rule (83 FR 59654 through 59661), 
creating the CQ and CO payment modifiers for services provided in whole 
or in part by PTAs and OTAs, respectively. These payment modifiers are 
required to be used on claims for services with dates of service 
beginning January 1, 2020, as specified in the CY 2020 PFS final rule 
(84 FR 62702 through 62708). We applied the 15 percent payment 
reduction to therapy services provided by PTAs (using the CQ modifier) 
or OTAs (using the CO modifier), as required by statute. Under sections 
1834(k) and 1848 of the Act, payment is made for outpatient therapy 
services at 80 percent of the lesser of the actual charge or applicable 
fee schedule amount (the allowed charge). The remaining 20 percent is 
the beneficiary copayment. For therapy services to which the new 
discount applies, payment will be made at 85 percent of the 80 percent 
of allowed charges. Therefore, the volume discount factor for therapy 
services to which the CQ and CO modifiers apply is: (0.20 + (0.80 * 
0.85), which equals 88 percent.
    For anesthesia services, we do not apply adjustments to volume 
since we use the average allowed charge when simulating RVUs; 
therefore, the RVUs as calculated already reflect the payments as 
adjusted by modifiers, and no volume adjustments are necessary. 
However, a time adjustment of 33 percent is made only for medical 
direction of two to four cases since that is the only situation where a 
single practitioner is involved with multiple beneficiaries 
concurrently, so that counting each service without regard to the 
overlap with other services would overstate the amount of time spent by 
the practitioner furnishing these services.
    <bullet> Work RVUs: The setup file contains the work RVUs from this 
proposed 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)[supcaret] 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 below in this proposed 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 below 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.

[[Page 32360]]

    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 two 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, 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, 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 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 3.
[GRAPHIC] [TIFF OMITTED] TP16JY25.007

    We are not proposing any changes to the equipment interest rates 
for CY 2026.
3. Adjusting RVUs To Match the PE Share of the Medicare Economic Index 
(MEI)
    In the past, we have stated that we believe that the MEI is the 
best measure available of 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). In the past, we 
have proposed (and subsequently finalized) to accomplish this by 
holding the work RVUs constant and adjusting the PE RVUs, MP RVUs, and 
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. As the MEI cost shares 
are updated, we would typically propose 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 2017-based 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.
    In the CY 2014 PFS proposed rule (78 FR 43287 through 43288) and 
final rule (78 FR 74236 through 74237), we detailed the steps necessary 
to accomplish this result (see steps 3, 10, and 18). The CY 2014 
proposed and final adjustments were consistent with our longstanding 
practice to make adjustments to match the RVUs for the PFS components 
with the MEI cost share weights for the components, including the 
adjustments described in the CY 1999 PFS final rule (63 FR 58829), CY 
2004 PFS final rule (68 FR 63246 and 63247), and CY 2011 PFS final rule 
(75 FR 73275).
    In the CY 2023 PFS final rule (87 FR 69688 through 69711), we 
finalized to rebase and revise the MEI to reflect more current market 
conditions faced by physicians in furnishing physicians' services 
(referred to as the ``2017-based MEI''). We also finalized a delay of 
the adjustments to the PE pools in steps 3 and 10 and the recalibration 
of the relativity adjustment in step 18 until the

[[Page 32361]]

public had an opportunity to comment on the rebased and revised 2017-
based MEI (87 FR 69414 through 69416). Because we finalized significant 
methodological and data source changes to the MEI in the CY 2023 PFS 
final rule and significant time had elapsed since the last rebasing and 
revision of the MEI in CY 2014, we believed that delaying the 
implementation of the finalized 2017-based MEI was consistent with our 
efforts to balance payment stability and predictability with 
incorporating new data through more routine updates. We refer readers 
to the discussion of our comment solicitation in the CY 2023 PFS final 
rule (87 FR 69429 through 69432), where we reviewed our ongoing efforts 
to update data inputs for PE to aid stability, transparency, 
efficiency, and data adequacy. We also solicited comments in the CY 
2023 PFS proposed rule on when and how to best incorporate the 2017-
based MEI into PFS ratesetting, and whether it would be appropriate to 
consider a transition to full implementation for potential future 
rulemaking. We presented the impacts of implementing the 2017-based MEI 
in PFS ratesetting through a 4-year transition and through full 
immediate implementation, that is, with no transition period in the CY 
2023 PFS proposed rule. We also solicited comments on other 
implementation strategies for potential future rulemaking in the CY 
2023 PFS proposed rule. In the CY 2023 PFS final rule, we discussed 
that many commenters supported our proposed delayed implementation, and 
many commenters expressed concerns with the redistributive impacts of 
the implementation of the 2017-based MEI in PFS ratesetting. Many 
commenters also noted the AMA's intent to collect practice cost data 
from physician practices, which could be used to derive cost share 
weights for the MEI and RVU shares.
    In CY 2025 PFS rulemaking (89 FR 97722), we stated that in light of 
the AMA's current data collection efforts and because the 
methodological and data source changes to the 2017-based MEI finalized 
in the CY 2023 PFS final rule would have significant impacts on PFS 
payments, similar to our discussion of this topic in the CY 2024 PFS 
rulemaking cycle (88 FR 78829 through 78831), we continued to believe 
that delaying the implementation of the finalized 2017-based MEI cost 
share weights for the RVUs was consistent with our efforts to balance 
payment stability and predictability with incorporating new data 
through more routine updates. For these reasons, we did not propose to 
incorporate the 2017-based MEI in PFS ratesetting for CY 2024 and CY 
2025. As we noted in the CY 2024 PFS final rule, many commenters on the 
CY 2024 PFS proposed rule supported our continued delayed 
implementation of the 2017-based MEI in PFS ratesetting (88 FR 78830). 
Most of these commenters recommended to us to pause consideration of 
other sources for the MEI until the AMA's efforts to collect practice 
cost data from physician practices concluded, although a few commenters 
recommended that we implement the MEI for PFS ratesetting as soon as 
possible. We stated that we agree with the commenters that it would be 
prudent, and avoid potential duplication of effort, to wait to consider 
other data sources for the MEI while the AMA's data collection 
activities were ongoing. We stated that as we discussed in the CY 2024 
PFS final rule, we continue to monitor the data available related to 
physician services' input expenses, but we were not proposing to update 
the data underlying the MEI cost weights at that time.
    At the time of publication of this proposed rule, the AMA has 
concluded their data collection efforts and, in early 2025, submitted 
data from its Physician Practice Information (PPI) and Clinician 
Practice Information (CPI) Surveys to CMS for us to consider 
implementing the PE/HR data and cost shares in PFS ratesetting for CY 
2026. We appreciate the AMA's data collection efforts, and recognize 
the significant efforts required to develop the survey and collect the 
data. We have prioritized review of the submitted information during 
the first part of this year based on our longstanding interest in the 
value of updated practice expense information. At this time, however, 
we have substantive concerns about the accuracy and suitability of the 
PPI and CPI Survey data as an immediate replacement for the current PE/
HR data and cost shares for use in CY 2026 PFS ratesetting. Due to 
overarching concerns with the data as described below and our 
previously described policy goal to balance PFS payment stability and 
predictability with incorporating new data through routine updates to 
the MEI, we are not proposing to implement the PE/HR or cost shares 
from the AMA's survey data at this time. Instead, we propose to 
maintain the current PE/HR and 2006-based MEI cost shares for CY 2026 
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 2026 direct PE input public use files, which are 
available on the CMS website under downloads for the CY 2026 PFS 
proposed rule at <a href="https://www.cms.gov/Medicare/Medicare-Fee-fafor-Service-Payment/PhysicianFeeSched/PFS-Federal-Regulation-Notices.html">https://www.cms.gov/Medicare/Medicare-Fee-fafor-Service-Payment/PhysicianFeeSched/PFS-Federal-Regulation-Notices.html</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,

[[Page 32362]]

order from physician confirmed and 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 
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, one 
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. As in previous calendar 
years, to facilitate rulemaking for CY 2026, we are continuing to 
display two versions of the Labor Task Detail public use file: one 
version with the old listing of clinical labor tasks and one with the 
same tasks crosswalked to the new listing of clinical labor activity 
codes. These lists are available on the CMS website under downloads for 
the CY 2026 PFS proposed rule at <a href="https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/PhysicianFeeSched/PFS-Federal-Regulation-Notices.html">https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/PhysicianFeeSched/PFS-Federal-Regulation-Notices.html</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, StrategyGen, which updated pricing recommendations for 
approximately 1,300 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 2019), 50/50 percent (CY 2020), 75/25 
percent (CY 2021), and 100/0 percent (CY 2022) split between new and 
old pricing. We believed 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

[[Page 32363]]

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 with comment period (83 FR 59473 through 59480).
    For CY 2026, we are proposing to update the price of 35 supplies 
and seven equipment items in response to the public submission of 
invoices following the publication of the CY 2025 PFS final rule. The 
42 supply and equipment items with proposed updated prices are listed 
in the valuation of specific codes section of the preamble under Table 
6, CY 2026 Invoices Received for Existing Direct PE Inputs.
    We received a series of invoices associated with the SD339 supply 
prior to our February 10th submission deadline and are proposing to 
update its pricing accordingly for CY 2026, as detailed in Table 6, CY 
2026 Invoices Received for Existing Direct PE Inputs. We later received 
additional invoices associated with this supply several months 
following our February 10th deadline which arrived too late to be 
included in the proposed updated pricing for this supply as shown in 
Table 6. Consistent with our previously finalized policy associated 
with the February 10th deadline (79 FR 67608), we will review these 
invoices during the comment period following the publication of this CY 
2026 PFS proposed rule for potential inclusion in the final rule.
    We are not proposing to update the price of another eight supplies 
and one equipment item, which were the subject of public submission of 
invoices. Our reasons for not proposing updates to these prices are 
detailed below, and we are soliciting additional information from 
interested parties for assistance in pricing these supplies:
    <bullet> Radiation treatment vault (ER056): We received pricing 
information associated with the radiation treatment vault from an 
interested party. However, this pricing information contained numerous 
costs associated with building construction which would not be included 
on a traditional invoice, such as surveying, plumbing and HVAC 
expenses, drywall packaging, and the installation of electrical 
equipment. As we previously stated in the CY 2021 PFS final rule about 
similar costs associated with proton beam treatment delivery services, 
the expenses associated with constructing new office facilities fall 
outside of our direct PE methodology and would be more accurately 
classified as a form of building maintenance or office rent under 
indirect PE (85 FR 84626). We do not agree that construction costs 
should be included as a form of direct PE because they are not 
individually allocable to a particular patient for a particular 
service. Therefore, we do not believe that it would serve the interests 
of relativity to include these building construction costs for the 
radiation treatment vault as a type of direct PE expense. In the 
absence of other pricing information associated with the radiation 
treatment vault, or pricing of the vault absent these building 
construction costs, we are proposing to maintain its current price of 
$773,104.
    <bullet> Congo red kits (SA110) and UltraView Universal DAB 
Detection Kit (SL488): We received three invoices from interested 
parties requesting an increase in the price of the SA110 supply from 
$6.80 to $20.12 and another three invoices from interested parties 
requesting an increase in the price of the SL488 equipment from $12.28 
to $41.26. In both cases, we do not understand how the typical price of 
these supplies could be increasing by such a large amount, tripling the 
current price in both cases, given that the price of both supplies was 
recently updated. Both the SA110 supply and the SL488 supply had their 
prices updated in the CY 2024 PFS final rule, with the SA110 supply 
increasing from $6.16 to $6.80 and the SL488 supply increasing from 
$9.70 to $12.28 (88 FR 78966 through 78967). We do not believe that the 
typical price for these supplies would increase to such a great degree 
given that their pricing was already recently updated for CY 2024; 
therefore, we are not proposing to update.
    <bullet> Catheter, balloon, rectal pressure (SD017); catheter, 
pressure, urodynamic (SD027); and transducer dome (pressure) (SD125): 
We received one invoice from interested parties for each of these three 
supplies. Interested parties requested an increase in the price of the 
SD017 supply from $35.89 to $74.00, an increase in the price of the 
SD027 supply from $19.35 to $86.80, and an increase in the price of the 
SD125 supply from $3.58 to 17.32. However, in each of these three 
cases, it was unclear if the item on the invoice matched the supply 
item in question. The invoice for the SD017 supply listed a ``Abdominal 
Sensor Catheter'', the invoice for the SD027 supply listed a ``Single 
Sensor Catheter'', and the invoice for the SD125 supply listed a 
``transducer cartridge with luer lock''. Given the differences between 
the names of the items in question, and the significant increases in 
requested pricing, we are not proposing to update the pricing of these 
three supplies as we cannot verify that the invoices refer to the same 
supply items.
    <bullet> Electrode, surface (SD062): We received one invoice from 
interested parties requesting a decrease in the price of the SD062 
supply from $1.58 to $0.34. The invoice appeared to state that there 
are 10 copies of 10 packs of 3 electrodes which, when dividing the 
total price of $103 by 300 electrodes, results in a price of $0.34 per 
electrode. We do not believe that the interested parties intended to 
submit an invoice resulting in a 78 percent decrease in pricing for the 
SD062 supply, and we are not convinced that we have correctly 
understood the unit quantity for this item. As a result, we are not 
proposing to change the pricing of the SD062 supply at this time.
    <bullet> Biohazard specimen transport bag (SM008): We received one 
invoice from interested parties requesting an increase in the price of 
the SM008 supply from $0.087 to $0.750, an increase of more than 750 
percent. However, when we reviewed the invoice, we determined that it 
referred to a different type of disposal bag than the biohazard 
specimen transport bag described by the SM008 supply, which explained 
the disparity in the pricing. We are therefore not proposing to update 
the pricing of the SM008 supply.
    <bullet> Wipes, lens cleaning (per wipe) (Kimwipe) (SM027): We 
received one invoice from interested parties requesting an increase in 
the price of the SM027 supply from $0.04 to $0.33, an increase of 
approximately 700 percent. However, when we reviewed the supply in 
question, we found that lens cleaning wipes were readily available for 
purchase at the current price of $0.04 per wipe. We are therefore not 
proposing to update the pricing of the SM027 supply.
(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, we will consider 
invoices submitted as public comments during the comment period 
following the publication of the PFS proposed rule and will consider 
any invoices received after February 10th or outside of the public 
comment

[[Page 32364]]

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#4010051f10322923251f092e3035341f15302421342500232d336e2828336e272f36"><span class="__cf_email__" data-cfemail="6d3d28323d1f040e083224031d181932381d090c19082d0e001e4305051e430a021b">[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 rulemaking. 
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 to implement 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 the 
preamble under Table 6, 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 8 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 preamble under Table 8, CY 2025 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 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 
through 97729), 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. 
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. Commenters 
requested that CMS either delay the pricing update or phase-in the 
supply pack changes over a four-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.

[[Page 32365]]

    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, 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 
(83 FR 59475). Based on this previously established policy, we 
finalized the use of a pricing transition for three supply packs in 
Table 4:
[GRAPHIC] [TIFF OMITTED] TP16JY25.008

    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, one-third of the difference between the CY 2025 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. For the other proposed supply packs, the cystoscopy drapes pack 
(SA045) is only included in 7 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 above. We therefore finalized each of them at their updated 
pricing for CY 2025 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 5:
[GRAPHIC] [TIFF OMITTED] TP16JY25.009

    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

[[Page 32366]]

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 above 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[dash]year pricing transition for three supply packs as described 
above.
    For CY 2026, we are proposing to continue implementing the supply 
pack pricing update and associated revisions as previously recommended 
by the RUC's workgroup. We are proposing to update the price of the 15 
supply packs detailed in Table 5 which were received too late in CY 
2025 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 are proposing these supplies 
move immediately to their final prices for CY 2026.
    For the 12 other supply packs, we are proposing 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 are proposing 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 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 last year for CY 2025, we are proposing the total supply 
pack pricing update detailed in Table 6:
[GRAPHIC] [TIFF OMITTED] TP16JY25.010

    This table also includes the hydrophilic guidewire (SD089) supply 
which we are proposing to transition in pricing over three 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.
c. Technical Corrections To Direct PE Input Database and Supporting 
Files
    Following the publication of the CY 2025 PFS final rule, we 
received a request from the RUC to remove all equipment items priced 
below $500 from the CMS ratesetting database. The RUC stated that since 
CMS has defined that medical equipment must be at least $500 and all 
equipment inputs under $500 are considered indirect expense, the 11 
current equipment items under this threshold should no longer be listed 
as equipment. The RUC requested that CMS remove these items from its 
equipment list and from the specific HCPCS codes to conform to the 
definition of direct medical equipment and to ensure that the rule 
remains consistently applied.
    We appreciate the RUC bringing this topic to our attention. 
However, we are not proposing to remove these 11 equipment items that 
fall under the $500 threshold from the CMS ratesetting database. These 
equipment items have historically been included as direct PE inputs in 
their respective HCPCS codes for the last two decades and, given the 
very small valuation associated with their use (such as the ED004 
digital

[[Page 32367]]

camera priced at approximately 0.06 cents per minute of use), we do not 
believe that it is necessary to remove them from the database. We 
believe that it better serves relativity by continuing to maintain 
these equipment items due to their historical inclusion in their 
associated HCPCS codes, as opposed to the removal of long-standing 
direct PE inputs which may cause unnecessary confusion and lead to 
concern that the valuation of these services would be negatively 
impacted. We are soliciting comments on whether to maintain or remove 
these equipment items.
    We also received a request from the RUC to update the names of 
several supplies and equipment items in the CMS ratesetting database. 
The RUC stated that these naming changes would remove specific product 
or brand names and more accurately describe the items in question. We 
agree with the RUC and we are proposing naming changes for the 
following supplies and equipment items:
    <bullet> EQ392: We are proposing to rename the ``heart failure 
patient physiologic monitoring equipment package'' to ``patient 
physiologic monitoring equipment package''.
    <bullet> ER089: We are proposing to rename the ``IMRT Accelerator'' 
to ``Radiation Treatment Delivery Linear Accelerator''.
    <bullet> SD253: We are proposing to rename the ``atherectomy device 
(Spectronetics laser or Fox Hollow)'' supply to ``atherectomy device''.
    <bullet> SD254: We are proposing to rename the ``covered stent 
(VIABAHN, Gore)'' to ``covered stent (VIABAHN)''.
    We received a separate request from the RUC for a technical 
correction involving CPT code 65780 (Ocular surface reconstruction; 
amniotic membrane transplantation, multiple layers). The RUC stated 
that there was a potential issue with the intraservice work time for 
CPT code 65780, which was recommended by the RUC with 35 minutes of 
work time and finalized by CMS with no work time refinements. However, 
CPT code 65780 was listed with 25 minutes of intraservice work time in 
the work time public use file issued with the CY 2025 PFS final rule; 
the RUC questioned whether this was a potential technical error. We 
have reviewed CPT code 65780 and concluded that the intraservice work 
time was unintentionally listed with the incorrect work time of 25 
minutes; we are proposing to correct this to the intended work time of 
35 minutes. We note that the total work time of 192 minutes was listed 
correctly for CPT code 65780 and does not require a technical 
correction.
    We also received a request from the RUC for a technical correction 
involving CPT code 15851 (Removal of sutures or staples requiring 
anesthesia (that is, general anesthesia, moderate sedation)). The RUC 
stated that CPT code 15851 continued to receive PE RVUs in the 
nonfacility setting despite no longer having any direct PE inputs 
following its review at the January 2022 RUC meeting. Since CMS 
finalized the RUC's recommended lack of direct PE inputs for CPT code 
15851 in the CY 2023 PFS final rule, the RUC questioned whether this 
was a potential technical error. We have reviewed CPT code 15851 and 
concluded that the continued assignment of PE RVUs in the nonfacility 
setting is an unintended technical error; we are proposing to correct 
this code by removing the nonfacility PE RVUs for CY 2026.
5. Development of Strategies for Updates to Practice Expense Data 
Collection and Methodology
a. Background
    The AMA PPIS was first introduced in 2007 as a means to collect 
comprehensive and reliable data on the direct and indirect PEs incurred 
by physicians (72 FR 66222). In considering the use of PPIS data, the 
goal was to improve the accuracy and consistency of PE RVUs used in the 
PFS. The data collection process included a stratified random sample of 
physicians across various specialties, and the survey was administered 
between August 2007 and March 2008. Data points from that period of 
time are integrated into PFS calculations today. In the CY 2009 PFS 
proposed rule (73 FR 38507 through 3850), we discussed the indirect PE 
methodology that used data from the AMA's survey that predated the 
PPIS. In CY 2010 PFS rulemaking, we announced our intent to incorporate 
the AMA PPIS data into the PFS ratesetting process, which would first 
affect the PE RVU. In the CY 2010 PFS proposed rule, we outlined a 4-
year transition period, during which we would phase in the AMA PPIS 
data, replacing the existing PE data sources (74 FR 33554). We also 
explained that our proposals intended to update survey data only (74 FR 
33530 through 33531). In our CY 2010 final rule, we finalized our 
proposal, with minor adjustments based on public comments (74 FR 61749 
through 61750). We responded to the comments we received about the 
transition to using the PPIS to inform indirect PE allocations (74 FR 
61750). In the responses, we acknowledged concerns about potential gaps 
in the data, which could impact the allocation of indirect PE for 
certain physician specialties and suppliers, which are issues that 
remain important today. The CY 2010 PFS final rule explains that 
section 212 of the Balanced Budget Refinement Act of 1999 (Pub. L. 106-
113, November 29, 1999) (BBRA) directed the Secretary to establish a 
process under which we accept and use, to the maximum extent 
practicable and consistent with sound data practices, data collected or 
developed by entities and organizations to supplement the data we 
normally collect in determining the PE component. BBRA required us to 
establish criteria for accepting supplemental survey data. Since the 
supplemental surveys were specific to individual specialties and not 
part of a comprehensive multispecialty survey, we had required that 
certain precision levels be met in order to ensure that the 
supplemental data was sufficiently valid, and acceptable for use in the 
development of the PE RVUs. At the time, our rationale included the 
assumption that because the PPIS is a contemporaneous, consistently 
collected, and comprehensive multispecialty survey, we do not believe 
similar precision requirements are necessary, and we did not propose to 
establish them for the use of the PPIS data (74 FR 61742). We noted 
potential gaps in the data, which could impact the allocation of 
indirect PE for certain physician and suppliers. The CY 2010 final rule 
adopted the proposal, with minor adjustments based on public comments, 
and explained that these minor adjustments were in part due to non-
response bias that results when the characteristics of survey 
respondents differ in meaningful ways, such as in the mix of practices 
sizes, from the general population (74 FR 61749 through 61750).
    Throughout the 4-year transition period, from CY 2010 to CY 2013, 
we gradually incorporated the AMA PPIS data into the PFS rates, 
replacing the previous data sources. The process involved addressing 
concerns and making adjustments as necessary, such as refining the PFS 
ratesetting methodology in consideration of interested party feedback. 
For background on the refinements that we considered after the 
transition began, we refer readers to discussions in the CY 2011 
through 2014 final rules (75 FR 73178 through 73179; 76 FR 73033 
through 73034; 77 FR 98892; 78 FR 74272 through 74276).
    In the CY 2011 PFS proposed rule, we requested comments on the 
methodology for calculating indirect PE RVUs, explicitly seeking input 
on using survey data, allocation methods, and

[[Page 32368]]

potential improvements (75 FR 40050). In our CY 2011 PFS final rule, we 
addressed comments regarding the methodology for indirect PE 
calculations, focusing on using survey data, allocation methods, and 
potential improvements (75 FR 73178 through 73179). We recognized some 
limitations of the current PFS ratesetting methodology but maintained 
that the approach was the most appropriate at the time. In the CY 2012 
PFS final rule, we responded to comments related to indirect PE 
methodology, including concerns about allocating indirect PE to 
specific services and using the AMA PPIS data for certain specialties 
(76 FR 73033 through 73034). We indicated that CMS would continue to 
review and refine the methodology and work with interested parties to 
address their concerns. In the CY PFS 2014 final rule, we responded to 
comments about fully implementing the AMA PPIS data. By 2014, the AMA 
PPIS data had been fully integrated into the PFS, serving as the 
primary source for determining indirect PE inputs (78 FR 74235). We 
continued to review data and the PE methodology annually, considering 
interested party feedback and evaluating the need for updates or 
refinements to ensure the accuracy and relevance of PE RVUs (79 FR 
67548). In the years following the full implementation of the AMA PPIS 
data, we further engaged with interested parties, thought leaders and 
subject matter experts to improve our PE inputs' accuracy and 
reliability. For further background, we refer readers to our 
discussions in final rules for CY 2016 through 2022 (80 FR 70892; 81 FR 
80175; 82 FR 52980 through 52981; 83 FR 59455 through 59456; 84 FR 
62572; 85 FR 84476 through 84478; 86 FR 62572).
    In our CY 2023 PFS final rule, we issued an RFI to solicit public 
comment on strategies to update PE data collection and methodology (87 
FR 69429 through 69432). We solicited comments on current and evolving 
trends in health care business arrangements, the use of technology, or 
similar topics that may affect or factor into PE calculations. As 
described in previous rulemaking, we have continued interest in 
developing a roadmap for updates to our PE methodology that account for 
changes in the health care landscape. Of various considerations 
necessary to form a roadmap for updates, we reiterate that allocations 
of indirect PE continue to present a wide range of challenges and 
opportunities. As discussed in multiple cycles of previous rulemaking, 
our PE methodology currently relies on AMA PPIS data, which we have 
maintained represented the best aggregated available source of 
information at the time of its implementation. We noted in our CY 2023 
and CY 2024 rules that there are several competing concerns that CMS 
must take into account when considering updated data sources, which 
also should support and enable ongoing refinements to our PE 
methodology.
b. Refreshed Data and Request for Information on Timing To Effectuate 
Routine Updates
    In the CY 2024 PFS proposed rule, we continued to encourage 
interested parties to provide feedback and suggestions to CMS that give 
an evidentiary basis to shape optimal PE data collection and 
methodological adjustments over time. Considering our ratesetting 
methodology and prior experiences implementing new data, we issued a 
follow-up from the CY 2023 comment solicitation for general 
information. We solicited comments from interested parties on 
strategies to incorporate information that could address known 
challenges we experienced in implementing the initial AMA PPIS data. 
Our current methodology relies on the AMA PPIS data, legislatively 
mandated supplemental data sources (for, example, we use supplemental 
survey data collected in 2003, as required by section 1848(c)(2)(H)(i) 
of the Act to set rates for oncology and hematology specialties), and 
in some cases crosswalks to allocate indirect PE as necessary for 
certain specialties and practitioner types. We also sought to 
understand whether, upon completion of the updated PPIS data collection 
effort by the AMA, contingencies or alternatives may be necessary and 
available to address the lack of data availability or response rates 
for a given specialty, set of specialties, or specific service 
suppliers who are paid under the PFS.
    In response to the CY 2024 RFI, most commenters stated that CMS 
should defer significant changes until the AMA PPIS results become 
available. For further background, refer to 88 FR 78841 through 78843. 
In responding to our RFI, the AMA RUC provided a set of responses, 
which many other commenters echoed in separate comments. In summary, 
the AMA RUC letter submission from CY 2024 suggested that CMS should 
not consider further changes until PPIS data collection and analysis is 
complete. Overall, the AMA comments generally do not support any change 
to the methodology and stated that CMS should wait to consider any 
further changes until PPIS updates become available. Further, we noted 
that through its contractor, Mathematica, the AMA secured an 
endorsement for the PPIS updates from each State society, national 
medical specialty society, and others prior to fielding the survey (88 
FR 78843). Refer to the AMA's summary of the PPIS, available at <a href="https://www.ama-assn.org/system/files/physician-practice-information-survey-summary.pdf">https://www.ama-assn.org/system/files/physician-practice-information-survey-summary.pdf</a>. The AMA stated that it expects analysis, reporting, and 
documentation to be completed by the end of CY 2024 and would share 
data with CMS when results become available.
    Some commenters did not recommend that CMS defer significant 
changes until the AMA PPIS results become available. These commenters 
stated that reliance on the PPIS updates may not improve the accuracy 
and stability of the PE methodology because of the survey design, 
possible implementation challenges, and a possible lack of transparency 
or granularity in resulting datasets. Other commenters stated that 
dependence on the PPIS or survey data in general, due to timing and 
frequency constraints, may continue to jeopardize independent practice 
and discourage fair competition among suppliers and providers of 
services paid under the PFS. These commenters assert that if current 
trends continue, it will result in far fewer independent practices and 
more consolidation before the availability of updated survey data, 
undermining the sampling methodology of any survey and the general 
goals of our PE methodology updates.
    As we stated in the CY 2025 proposed rule (89 FR 61614), we believe 
the AMA's approach may possibly mitigate nonresponse bias, which 
created challenges using previous PPIS data. However, we remain 
uncertain about whether endorsements prior to fielding the survey may 
inject other types of bias in the validity and reliability of the 
information collected. We believe it remains important to reflect on 
the challenges with our current methodology, and to continue to 
consider alternatives that improve the stability and accuracy of our 
overall PE methodology. We reiterate our discussion summarizing the 
responses to previous years' RFIs in each of the CY 2023 and CY 2024 
final rules (refer to 87 FR 69429 through 69432 and 88 FR 78841 to 
78843). We also requested general information from the public on ways 
that CMS may continue work to improve the stability and predictability 
of any future updates. Specifically, we

[[Page 32369]]

requested feedback from interested parties regarding scheduled, 
recurring updates to PE inputs for supply and equipment costs. We 
stated that we believe that establishing a cycle of timing to update 
supply and equipment cost inputs every 4 years may be one means of 
advancing shared goals of stability and predictability. CMS would 
collect available data, including, but not limited to, submissions and 
independent third-party data sources, and propose a phase-in period 
over the following 4 years. The phase-in approach maps to our 
experience with previous updates. Additionally, we stated that more 
frequent updates may have the unintended consequence of 
disproportionate effects of various supplies and equipment that have 
newly updated costs.
    Further, we solicited feedback in the CY 2025 proposed rule RFI (89 
FR 61614) on possible mechanisms to establish a balance whereby our 
methodology would account for inflation and deflation in supply and 
equipment costs. We stated that we remain uncertain how economies of 
scale (meaning a general principle that cost per unit of production 
decreases as the scale of production increases) should or should not 
factor into future adjustments to our methodology. We stated that there 
remains a diversity of perspectives among interested parties about such 
effects. We sought information about specific mechanisms that may be 
appropriate, and in particular, approaches that would leverage 
verifiable and independent third-party data that is not managed or 
controlled by active market participants.
    In response to our CY 2025 proposed rule RFI (89 FR 97737), 
numerous commenters expressed concerns regarding CMS's current PE 
methodology, particularly highlighting its perceived inadequacies in 
accommodating modern medical technologies and services, such as 
Software as a Service (SaaS) and artificial intelligence (AI). These 
commenters stated that there is a need for CMS to revise its PE 
methodology to better reflect the actual costs of running medical 
practices today, which includes more frequent updates and the 
incorporation of direct costs for software and innovative technologies. 
Many also supported the AMA's PPIS efforts to ensure updated and 
accurate data informs PE calculations. Commenters urged CMS to 
collaborate closely with medical associations and incorporate broad 
stakeholder feedback without increasing reporting burdens, particularly 
for smaller practices.
    We note that we have an ongoing contract with the RAND Corporation 
to analyze and develop alternative methods for measuring PE and related 
inputs for implementation of updates to payment under the PFS. We will 
continue to study possible alternatives and have included analysis of 
the updated PPI and CPI Survey data in this proposed rule, as part of 
our ongoing work.
    As previously stated above and discussed in sections II.N. and VI. 
of this proposed rule, we acknowledge that, at the time of publication 
of this proposed rule, the AMA concluded their data collection efforts 
and has submitted the data to CMS for us to consider implementing the 
PE/HR data and cost shares in PFS ratesetting for CY 2026. In the 
current system, accurate measurement of the indirect to direct PE ratio 
and the PE/HR for each specialty is critical to ensure that allocated 
indirect PE RVUs (and therefore total PE RVUs) accurately estimate 
service-level PE as defined by PFS ratesetting steps described above. 
Because the PE methodology is budget neutral, inaccuracies in the PE/HR 
data for some specialties can significantly impact the overall pool of 
PE available to distribute across all services, and therefore overall 
valuation and payment.
    We appreciate the AMA's PPI and CPI Survey data collection efforts, 
and recognize the significant costs incurred to collect the data. 
However, our initial review of the new data raises substantive concerns 
about their accuracy, utility, and suitability as an immediate 
replacement for the current PE/HR data and cost shares for use in 
allocating nearly $91 billion in payments across PFS services. These 
concerns relate to issues including:
    <bullet> Low Response Rates and Representativeness: A primary 
concern is the low response rate of the surveys. The 2024 PPI Survey 
had a response rate of 3 to 7 percent, depending on whether practices 
that did not click through the invitation email link were counted as 
non-respondents. The CPI Survey had a slightly higher response rate 
between 7 to 9 percent. In comparison, the 2008 PPIS had a response 
rate of 12 percent. Low response rates raise concerns as to whether 
responding practices are systematically different from sampled 
practices that did not or could not respond. Additionally, in response 
to lower-than-expected response rates, the AMA allowed 102 practices to 
volunteer to participate in the survey. Although most of these 
volunteer practices did not complete the survey, allowing practices to 
volunteer data adds to concerns about the representativeness of the 
data.
    Additionally, the 2008 PE/HR estimates were based on the 
observations (about half of responses) that had no missing expense 
data, whereas the 2024 PE/HR estimates and the shares are based on 
observations that had at least some non-missing data where the missing 
data was imputed as described in the Survey Methods Report (Step 6).\1\ 
It should be noted that some expense categories were reported more 
consistently by survey respondents. For example, 97 percent of the 
respondents reported compensation (physician work) compared to only 69 
percent that were able to report non-billable drugs (direct expense 
under supplies) and information technology (indirect expense). 
Similarly, many survey respondents were not able to separately report 
expenses for qualified health providers (QHPs). Nearly 40 percent of 
the responses used in the calculation of the PE/HR estimates reported 
that they had nurse practitioners or physician assistants in their 
practice, but only 27 percent were able to separately report non-
physician compensation expenses.

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

    <bullet> Small Sample Sizes and Sampling Variation: Due in part to 
the low response rates, the number of respondents was small for many 
specialties included in the 2024 PPI and CPI data. For example, the PE/
HR measures for Vascular Surgery are based upon responses from only 20 
practices. Moreover, the PPI and CPI survey estimates give more weight 
to responses from practice types that would otherwise be under-
represented in the sample, relative to the population of all eligible 
practices in a given specialty. For example, such an adjustment would 
be applied if the sample contained a higher proportion of facility-
based practices than there are in the full population of practices in a 
given specialty. Applying such weights generally results in estimates 
that are less precise than an unweighted sample of a given size. One 
way to quantify this is via the effective sample size, which estimates 
the sample size from an unweighted sample that would be required to 
produce survey estimates that are as precise as those from the weighted 
sample. The effective sample size can be estimated as the ratio of the 
sample size to the design effect, which is reported in the PPI/CPI 
Methods Reports.<SUP>2 3</SUP> For Vascular Surgery, the

[[Page 32370]]

reported design effect is 1.82, meaning that the 20 observations 
correspond to an effective sample size of only 11 (calculated as 
11.0=20/1.82). For 12 of 18 broad specialty groupings reported in the 
2024 PPI Survey, the effective sample size is less than 18.0 and for 
four of these specialties the effective sample size is less than 10.0. 
Similarly, in the CPI Survey data, the effective sample sizes are also 
small, with all but one below 20.0, and as low as 6.2 for Oral Surgery. 
Not including practices that volunteered, only 327 sampled practices 
completed the 2024 PPI Survey compared to 3,088 anticipated 
completions.
---------------------------------------------------------------------------

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

    The low sample sizes contribute to substantial statistical 
uncertainty regarding the true specialty-level PE/HR measures. Figure 
A-B1 illustrates the 95 percent confidence intervals for direct and 
indirect PE/HR as reported in the 2024 PPI/CPI Surveys. The large 
points represent the new PE/HR estimates, the bars indicate the 
confidence intervals, and the smaller points show the current PE/HR 
estimates used in PFS ratesetting from the 2008 PPIS. The 2024 CPI and 
PPI Survey confidence intervals are so broad that they cover most of 
the original 2008 PPI PE/HR values in nominal dollars (that is, not 
adjusted for inflation). Therefore, in most cases, the new data are 
unable to establish statistically significant changes from the status 
quo, especially since the old PE/HR measures were themselves estimated 
with substantial levels of statistical uncertainty. Even so, the new 
PE/HR estimates differ enough from the old ones that many specialty-
level impacts of adopting the new data are quite large. When translated 
into RVUs, the PE/HR standard errors for specialties such as 
Cardiology, Pathology, Ophthalmology, and Vascular Surgery correspond 
to a wide range of payments for services provided by those specialties 
meaning that the new data are compatible with a wide range of specialty 
impacts for many specialties.
    <bullet> Lack of Comparability to Previous Survey Data: The 2024 
PPI and CPI Survey data groups specialties in a considerably different 
way from the current structure, with 29 specialty groupings compared to 
51 in the 2008 data. We found that using the 2008 PE/HR data averaged 
within the 2024 PPI Survey specialty groupings would lead to large 
specialty-level impacts in some cases, further complicating comparisons 
between the old and new data and indicating that the new 2024 specialty 
groupings is impactful on redistribution among the PFS alone. We refer 
readers to section VI. of this proposed rule for discussion of the 
impacts of the 2024 PPI Survey specialty groupings on PFS ratesetting. 
It is also unclear why some specialties were collapsed into relatively 
broad groups for the purposes of data collection and reporting while 
others were not.
    <bullet> Potential Measurement Error: We are concerned that sampled 
practices were not able to accurately report the data necessary to 
respond to the PPI and CPI Surveys. For example, the survey contractor 
found that practices frequently had challenges reporting the number of 
physicians working in the practice. One may expect that the number of 
physicians in a practice is relatively easier for practices to measure 
than some of the specific costs integral to reporting PE/HR. However, 
the contractor noted that--prior to an adjustment--their estimate of 
the total number of physicians was nearly three times as large as the 
number of physicians in their sampling frame which ``indicated a large 
potential for measurement error in this estimate.'' \4\ Also, because 
information on the number of physicians in each practice was available 
from external data which were obtained before survey data were 
collected, to inform the survey design, we believe it is likely that 
the number of physicians was highlighted as having high potential 
measurement error because it was possible to compare this measure 
against external data. Moreover, some responding practices reported 
that it took more than 40 hours to complete the survey, which suggests 
that the required data are not readily captured by their accounting 
systems and therefore may not be fully reliable.

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

    Thus, we are left with doubts about not just the amount of data 
collected, but its quality as well.
    <bullet> Missing and Incomplete Data Submission: The PPI Survey 
summary data was submitted to CMS in January 2025 and the CPI Survey 
summary data in February 2025. These initial submissions were missing 
from many of the elements required to analyze the data and determine 
their usability in our PE methodology. We inquired about these elements 
and have since received some additional information, but some of the 
information was not available due to the survey contract concluding, 
such as estimates based solely on the survey responses that had no 
missing expense data or the impact of the trims and edits of the data 
described in the PPI Survey Methods Report. Additionally, some data is 
completely missing from the submission, therefore we had to utilize old 
PE/HR data in analyses for specialties such as Independent Diagnostic 
Testing Facilities (IDTFs) when developing models to incorporate the 
data. Additionally, the American Occupational Therapists Association 
(AOTA) requested the continued crosswalk of PE/HR data from Physical 
Therapy to Occupational Therapy because the CPI respondents may have 
indirectly reported the salaries of occupational therapy assistants 
with provider compensation rather than including their salaries in 
clinical staff compensation.
    Additionally, there is summary data provided from the PPI Survey 
\5\ that are not provided for the CPI Survey.\6\ For example, the PPI 
Survey summary data include two lines--``MEI shares'' and ``All 
[specialties]''--that could presumably be used to establish the share 
of total RVUs that should be attributed to work, practice expense, and 
malpractice, but we do not believe that they reflect the specialties' 
data from the CPI Survey, even though those specialties are included in 
PFS ratesetting, account for a significant portion of the PFS PE RVU 
pool, and draw from the same pool of RVUs as the PPI Survey 
specialties. Similarly, we do not have the corresponding CPI Survey 
specialty weighting information provided to CMS for the PPI Survey 
specialties, therefore, we have limited information to develop an 
approach for calculating shares for all CMS specialties accounted for 
in both the PPI and CPI Surveys.

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

    In an effort to incorporate PPI and CPI Survey specialties' data 
despite the lack of analogous summary data, we developed possible 
methods to weight the data for all CMS specialties in a cohesive manner 
for use in the PFS PE methodology such as estimates of total RVUs and 
total service time by specialty used for CY 2026 PFS ratesetting. We 
refer readers to section VI. of this proposed rule for discussion of 
the different weighting methodologies and their resulting shares of 
work, PE, and MP.
    Overall, the small sample sizes and the apparent presence of high 
levels of measurement error in data elements that could be compared to 
external estimates suggest that specialty-level PE/HR measures may be 
challenging to measure reliably through voluntary surveys alone. We 
note that the

[[Page 32371]]

interested parties may concur with this assertion based on the Methods 
Report, which states considerations for future data collection efforts 
that may forego the survey structure and rely on other practice expense 
sources such as tax returns. We believe that a more efficient and 
transparent system that could be updated on a regular basis may be 
possible using available administrative data (such as Medicare claims; 
hospital cost reports; publicly-reported tax information such as from 
IRS Form 990; and data collected by other agencies, such as the Census 
Bureau's Service Annual Survey (SAS)) to the fullest extent possible 
and relying on survey data only to fill gaps only where available data 
do not exist. An alternative to collecting any survey data would be to 
modify the PE allocation system so that it only relies only on data 
that can be measured accurately and on an on-going basis. For example, 
if there are components of indirect PE that are not captured in 
administrative data, those expense categories could potentially be re-
classified as direct costs and accounted for in a manner similar to how 
direct costs are currently considered.
    Beyond the use of the data in our PE methodology, we need 
information on the total share of PFS payments that should be allocated 
for work, PE, and MP. Data collected in the 2024 PPI and CPI Surveys 
could be used for this purpose, as well as potentially be considered in 
a construction of the MEI in the future; however, there still remain 
underlying concerns with the sample representativeness for these 
purposes. The AMA has asserted that shares derived from data collected 
from the Service Annual Survey (SAS) for the 2017-based MEI miss many 
physicians who work in facility settings and thereby understate the 
percent of total PFS payments that should be allocated to physician 
work. The data needed to derive the three component shares (work, PE, 
and MP) are more aggregated than the specialty-level PE/HR data 
required for the PE methodology, so we have fewer concerns with the 
small sample sizes for this application. However, we continue to have 
similar concerns with the data related to measurement error and sample 
representativeness for purposes of the shares.
BILLING CODE 4120-01-P

BILLING CODE 4120-01-C
    At the time of the publication of this proposed rule, we continue 
to conduct ongoing analyses on the potential impact of the AMA's PPI 
and CPI Survey data on PFS ratesetting. Due to overarching concerns 
with the data described above and our previously described policy goal 
to balance PFS payment stability and predictability with incorporating 
new data through routine updates to the MEI, we reiterate that we are 
not proposing to implement the PE/HR data or cost shares from the AMA's 
survey data at this time, and are proposing instead to maintain the 
current PE/HR data and cost shares for CY 2026 PFS ratesetting. At the 
same time, we remain focused on proposals that reflect evolutions in 
practice, including the site of service payment differential discussed 
below, while we continue to hold strong interest in specialty-level 
practice expense updates. Consequently, we intend to work with 
interested parties, including the AMA, to understand whether and how 
such data should be used in PFS ratesetting in future rulemaking.
c. Updates to Practice Expense (PE) Methodology--Site of Service 
Payment Differential
    While we are not proposing to incorporate the PPI and CPI Survey 
data into PFS ratesetting for CY 2026, we are proposing a significant 
refinement to our PE methodology to better reflect trends in physician 
practice settings. As detailed in the description of the

[[Page 32373]]

practice expense methodology above, many services have a site of 
service payment differential between the facility (F) and nonfacility 
(NF) settings under the PFS. Services furnished in the nonfacility 
setting, such as a physician's office, include the physician work RVUs, 
direct costs for supplies, clinical staff, and equipment, and indirect 
costs allocated based on the direct costs and the greater of either the 
clinical labor costs or the physician work RVUs. In the facility 
setting, the payment rate includes physician work RVUs and the indirect 
practice expense allocated based on the physician work RVU. The direct 
costs in the facility setting are paid under a different payment system 
than the PFS, such as the OPPS. Indirect costs allocated to services 
furnished in the facility setting are meant to reflect the typical 
costs associated with practice expenses in that setting of care.
    In the decades since implementing the PE methodology, there have 
been significant transformations to the landscape of the healthcare 
delivery system in the United States, particularly regarding physician 
practice patterns. Historically, private practice was the dominant 
model for physicians, offering them autonomy, flexibility, and the 
opportunity to build independent practices. Specifically, in 1988, 
approximately 72 percent of physicians were full or part owners in 
their practice.\7\ This percentage had dropped to 35.4 percent by 2024, 
representing a 52 percent decrease, with a corresponding rise in 
physicians in hospital-owned practices and physicians employed directly 
by a hospital. The percentage of physicians in hospital-owned practices 
has increased by over 47 percent, from 23.4 percent in 2012 to 34.5 
percent in 2024. Similarly, 12.2 percent of physicians were employed 
directly by a hospital (or contracted directly with a hospital) in 
2024, up from 5.6 percent in 2012.\8\ In their June 2025 Report to 
Congress,\9\ MedPAC notes that there are 9 specialties where 60 percent 
of the clinicians who billed Medicare furnished 90 percent or more of 
their services in the facility setting. These trends indicate a steady 
decline in the percentage of physicians working in private practice, 
with a corresponding rise in physician employment by hospitals; and 
growth in the percentage of physicians who practice exclusively, or 
almost exclusively, in the facility setting. When the PFS was 
established, the methodology for allocating indirect practice expense 
was based in part on an assumption that the physician maintained an 
office-based practice even when also practicing in a facility setting. 
In that context, the PE methodology has allocated the same amount of 
indirect costs per work RVU, without regard to setting of care.

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

    We note that, in the AMA's comment letter on the CY 2023 PFS 
proposed rule,\10\ they stated that physician practices maintain some 
indirect practice expense costs for physicians who are solely facility-
based such as coding, billing, and scheduling. We acknowledge that 
these indirect costs should be accounted for in PFS payment through PE 
RVUs, but we believe that allocating the same amount of indirect 
practice expense based on work RVUs in both settings may overstate the 
range of indirect costs incurred by facility-based physicians if it is 
now less likely that they would maintain an office-based practice 
separate from their facility practice. In a 2018 report developed under 
contract with CMS, RAND noted that ``operating from the perspective of 
paying for the `typical' instance of a procedure, these analyses 
suggest that the current system could be improved by shifting more of 
the allocation of PE RVUs to the physician office setting''.\11\ As 
MedPAC notes in their June 2025 report, ``In cases when clinicians 
practice exclusively or almost exclusively in a facility, or where a 
facility is financing indirect PE for clinicians, payment to both 
entities for indirect PE costs may be duplicative and unnecessary''. 
While the relative relationship between the PE allocated to services 
furnished in a facility and nonfacility setting may have been more 
reflective of the actual expenses incurred by physicians when the PE 
methodology was originally established, maintenance of that element of 
the methodology in the face of changing practice patterns likely 
represents an imbalance of the practice expense allocated to the 
facility relative to the nonfacility. Within the PFS relative value 
system, any overstatement of practice expenses in the facility setting 
would affect the allocation of indirect costs in the nonfacility 
setting. This dynamic, in which relative resources involved in 
furnishing PFS services may not be adequately reflected in facility and 
nonfacility settings, has the potential to contribute to broader 
undesirable financial incentives toward higher-priced settings of care, 
like hospitals, and away from more efficient settings, like physician 
offices.\12\ \13\ \14\ This could result in unnecessary costs for 
payers and beneficiaries, and obstacles to physicians and other 
professionals operating independent practices.

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

    We share MedPAC's concerns regarding the potential for duplicative 
payment under the current PE methodology for allocating indirect costs 
for physicians practicing in the facility setting. Allocating the same 
amount of indirect PE per work RVU for services furnished in the 
facility setting as the nonfacility setting may no longer reflect 
contemporary physician practice trends. As we noted above, data 
suggests that fewer than half of physicians currently own their 
practices, but the underlying assumption embedded in the PFS payment 
methodology presumed that physicians generally maintained office 
practices (and incurred associated indirect costs) even when they 
furnished care in facility settings. For these reasons, for each 
service valued in the facility setting under the PFS, we are proposing 
to reduce the portion of the facility PE RVUs allocated based on work 
RVUs to half the amount allocated to nonfacility PE RVUs beginning in 
CY 2026. This proposed change would occur in step 8 of the PE RVU 
Methodology described earlier in this section, in which indirect 
allocators (direct costs, clinical labor, and work RVUs) are assigned. 
For example, the work RVU for CPT code 33533 (Coronary artery bypass, 
using arterial graft(s); single arterial graft) is 33.75. For CY 2025, 
using the full work RVU as an indirect allocator, CPT code 33533 had 
approximately 12 indirect PE RVUs. Under this proposed change to the

[[Page 32374]]

methodology, where we would reduce the portion of the facility PE RVUs 
allocated based on work RVUs to half the amount allocated to 
nonfacility PE RVUs, CPT code 33533 would have approximately 7.2 
indirect PE RVUs.
    We note that this proposed change to the indirect cost allocation 
methodology is intended to better recognize the relative resources 
involved in furnishing services paid under the PFS in facility and 
nonfacility settings. We compare this proposed change to our current 
methodology, which functionally presumes 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 above, appears to be inconsistent with 
contemporary trends in physician practice. We understand from the AMA's 
comment letter on the CY 2023 PFS proposed rule noted above that 
physician practices may incur some indirect PE costs (such as coding, 
billing, and scheduling) for physicians who are facility-based. To 
better inform our consideration of how to account for any such costs in 
the PE RVU methodology, we are seeking comment on the specific types 
and magnitude of indirect PE costs incurred that are attributable to 
physicians who practice in part or exclusively in a facility setting, 
and any variables that affect whether and to what extent a practice 
would incur them. We are also seeking 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 nonfacility PE RVUs is an 
appropriate reduction or whether we should consider a different 
percentage reduction for CY 2026 or in future years. While our proposed 
change to the methodology represents a starting point to correcting 
potential historic distortions in the allocation of indirect PE costs 
across settings of care, we intend to further examine our methodology 
and consider additional refinements based upon public comments received 
and any studies or data sources identified. We are seeking comments on 
whether there are additional data sources that might help identify a 
more precise site of service difference in the allocation of indirect 
PE RVUs. We believe the implementation of this proposal would more 
accurately account for the resource costs involved in physicians 
furnishing care across all settings and correct potential distortions 
in the allocation of indirect PE under our current methodology. We 
refer readers to section VI. of this proposed rule for discussion of 
the impacts of this proposal on CY 2026 PFS ratesetting.
    We are specifically soliciting comments on whether and how this 
proposed policy should apply to codes with MMM global periods 
(maternity services) and how it could specifically impact access to 
maternity services, given our understanding that many of the patient 
encounters across those services occur in the office setting. As we 
noted in the CY 2024 PFS final rule (88 FR 78949), maternity services 
are unique within the PFS in that they are the only global codes that 
provide a single payment for almost 12 months of services, which 
include a relatively large number of E/M visits performed along with 
delivery services and imaging; and were valued using a building-block 
methodology as opposed to the magnitude estimation method. Given that 
the work RVUs for maternity services encompass significant care during 
this lengthy period that may be furnished in the nonfacility setting, 
we are soliciting comment on whether we should include these services 
in our proposed policy to reduce the allocation of PE based on work in 
the facility setting.
    We welcome comments on all aspects of this proposal, including ways 
to improve the allocation of facility and nonfacility PE RVUs in the 
future. We also seek comments on alternative approaches to improving 
the allocation of indirect PE as outlined in Chapter 1 of MedPAC's June 
2025 Report to the Congress (pages 27 through 33).
d. Use of OPPS Data for PFS Ratesetting
    For several kinds of PFS services, we are proposing to deviate from 
the use of the AMA survey data, and instead utilize data from 
auditable, routinely updated hospital data to either set relative or 
absolute rates, especially for technical services paid under the PFS. 
This approach promotes price transparency across settings, offers more 
predictable ratesetting outcomes, and limits the influence of 
anecdotal/survey data. We refer readers to sections II.E.24 and II.E.30 
of this proposed rule for specific proposals related to radiation 
treatment delivery and superficial radiation therapy services and 
remote patient monitoring and remote therapeutic monitoring services 
respectively and section II.K of this proposed rule for specific 
proposals related to skin substitutes. Although we are proposing 
different methodologies for use of OPPS data based on service type, we 
are seeking comment on whether it would be preferable to adopt a single 
methodology, such as a scaler and how such a methodology would account 
for differences in practice expenses between services, such as services 
with extensive clinical staff time versus services where the valuation 
is primarily driven by the equipment costs.
6. Payment for Services in Urgent Care Centers
    In the CY 2025 PFS proposed rule (89 FR 61746 through 61747), we 
sought comment on urgent care centers, noting that interested parties 
describe that hospital emergency departments are often used by 
beneficiaries to address non-emergent urgent care needs that could be 
appropriately served in less acute settings, but where other settings, 
such as physician offices, urgent care centers or other clinics, are 
not available or readily accessible. Patients enter EDs to treat common 
conditions like allergic reactions, lacerations, sprains and fractures, 
common respiratory illnesses (for example, flu or RSV), and bacterial 
infections (for example, strep throat, urinary tract infections or 
foodborne illness). Conditions like these often can be treated in less 
acute settings. We stated that we were interested in system capacity 
and workforce issues broadly and are interested in hearing more on 
those issues, including how entities such as urgent care centers can 
play a role in addressing some of the capacity issues in emergency 
departments.
    In response to our CY 2025 PFS proposed rule (89 FR 61746 through 
61747) question about whether the current ``Urgent Care Facility'' 
Place of Service code (POS 20) adequately identify and define the scope 
of services furnished in such settings other than the existing place of 
service codes,, commenters stated that the current place of service 
(POS) definitions are inadequately differentiated, especially if CMS 
wishes to encourage proliferation of the type of urgent care centers 
that can provide suitable alternatives to EDs, noting that POS 11 
generally refers to physician offices that provide diagnostic and 
therapeutic care in an office setting, by appointment, typically during 
regular business hours; POS 17 generally refers to clinics that are 
attached to retail operations, such as pharmacies, grocery stores or 
big box stores, and provide low-acuity primary and preventive health 
care, such as vaccinations; and POS 20 refers to Urgent Care Facilities 
but does not adequately differentiate between those that offer services 
more akin to the typical general practitioner's office and those that 
offer enhanced diagnostic and therapeutic services and extended

[[Page 32375]]

hours. They recommended that the creation of a new POS code describing 
``enhanced''' urgent care centers that offer specific diagnostic and 
therapeutic services and that operate outside typical business hours 
could fill this need. In response to our CY 2025 PFS proposed rule (89 
FR 61746 through 61747) question about whether the current ``Urgent 
Care Facility'' Place of Service code (POS 20) adequately identify and 
define the scope of services furnished in such settings other than the 
existing code set and valuation, they stated that Medicare's fee-for-
service payment systems do not recognize and adequately value services 
furnished in Urgent Care Clinics (UCCs) and stated that while there is 
some overlap in the types of professional services furnished in UCCs 
and physician offices, UCCs that operate for extended hours and that 
have enhanced diagnostic and therapeutic capabilities incur additional 
costs to provide these services.
    In recent months, an interested party has requested that for CY 
2026, we consider adopting a new Place of Service code for ``enhanced'' 
urgent care centers as well as create a new add-on G-code to describe 
the resource costs involved when practitioners furnish certain services 
in enhanced urgent care centers that offer extended hours and certain 
diagnostic and therapeutic services. The interested party suggested the 
following descriptor: ``Visit complexity inherent to evaluation and 
management associated with medical care services that serve as the 
immediate focal point for all needed urgent, non-emergent health care 
services and/or with urgent, non-emergent medical care services that 
are related to diagnosis and treatment of an unscheduled, ambulatory 
patient's urgent, non-emergent conditions. (Add-on code, list 
separately in addition to office/outpatient evaluation and management 
visits, new or established)'' and recommended that it be valued based 
on a crosswalk to HCPCS code G2211 (Visit complexity inherent to 
evaluation and management associated with medical care services that 
serve as the continuing focal point for all needed health care services 
and/or with medical care services that are part of ongoing care related 
to a patient's single, serious condition or a complex condition. (add-
on code, list separately in addition to office/outpatient evaluation 
and management visit, new or established) and made billable with all 
levels of office/outpatient E/M visits for both new and established 
patients when services are furnished in an enhanced urgent care center.
    We are seeking comments from the public regarding whether separate 
coding and payment is needed for evaluation and management visits 
furnished at urgent care centers, including whether or not an add-on 
code would be appropriate or if a new set of visit codes would be more 
practical We note that the process for requesting new place of service 
codes or modification of existing place of service codes is described 
on the CMS website at <a href="https://www.cms.gov/medicare/coding-billing/place-of-service-codes/process-requesting-new-codes-modification-existing-codes">https://www.cms.gov/medicare/coding-billing/place-of-service-codes/process-requesting-new-codes-modification-existing-codes</a>. Additionally, as discussed in Section II.B of this 
proposed rule, many PFS services have a site of service payment 
differential between the facility and nonfacility settings under the 
PFS. Services furnished in the nonfacility setting, such as a 
physician's office, include direct costs for supplies, clinical staff, 
and equipment, the physician work RVU and indirect practice expense 
allocated based on the direct costs and the physician work RVU. In the 
facility setting, the payment rate includes physician work and the 
indirect practice expense allocated based on physician work. The direct 
costs in the facility setting are paid under a different payment system 
other than the PFS, such as the OPPS. PE allocated to services 
furnished in the facility setting is meant to reflect typical costs 
associated with practice expenses in that setting of care. We note that 
we are proposing a change in our PE RVU methodology to better recognize 
variations in indirect costs between facility and nonfacility settings 
of care in section II.B of this rule. We note here that we are likewise 
interested in understanding how practice costs, including but not 
limited to indirect costs, may vary among different nonfacility 
settings of care. We are also interested in receiving feedback 
regarding how either the code set, or the PE methodology might be 
improved to better recognize the relative resources involved in 
furnishing services across these kinds of settings.

C. Potentially Misvalued Services Under the PFS

1. Background
    Section 1848(c)(2)(B) of the Act directs the Secretary to conduct a 
periodic review, not less often than every 5 years, of the relative 
value units (RVUs) established under the PFS. Section 1848(c)(2)(K) of 
the Act requires the Secretary to periodically identify potentially 
misvalued services using certain criteria and to review and make 
appropriate adjustments to the relative values for those services. 
Section 1848(c)(2)(L) of the Act also requires the Secretary to develop 
a process to validate the RVUs of certain potentially misvalued codes 
(PMVC) under the PFS, using the same criteria used to identify PMVC, 
and to make appropriate adjustments.
    As outlined in section II.E. of this proposed rule, under Valuation 
of Specific Codes, each year we develop appropriate adjustments to the 
RVUs taking into account recommendations provided by the American 
Medical Association (AMA)/Specialty Society Relative Value Scale (RVS) 
Update Committee (referred to as the RUC), MedPAC, and other interested 
parties. For many years, the RUC has provided us with recommendations 
on the appropriate relative values for new, revised, and potentially 
misvalued PFS services. We review these recommendations on a code-by-
code basis and consider these recommendations in conjunction with 
analyses of other data, such as claims data, to inform the decision-
making process as authorized by statute. We may also consider analyses 
of work time, work RVUs, or direct practice expense (PE) inputs using 
other data sources, such as the Veterans Health Administration (VHA), 
National Surgical Quality Improvement Program (NSQIP), the Society for 
Thoracic Surgeons (STS), and the Merit-based Incentive Payment System 
(MIPS) data. In addition to considering the most recently available 
data, we assess the results of physician surveys and specialty 
recommendations submitted to us by the RUC for our review. We also 
consider information provided by other interested parties such as from 
the general medical-related community and the public. We conduct a 
review to assess the appropriate RVUs in the context of contemporary 
medical practice. We note that section 1848(c)(2)(A)(ii) of the Act 
authorizes the use of extrapolation and other techniques to determine 
the RVUs for physicians' services for which specific data are not 
available and requires us to take into account the results of 
consultations with organizations representing physicians who provide 
the services. In accordance with section 1848(c) of the Act, we 
determine and make appropriate adjustments to the RVUs.
    In its March 2006 Report to the Congress (<a href="https://www.medpac.gov/document/report-to-the-congress-2006-medicare-payment-policy/">https://www.medpac.gov/document/report-to-the-congress-2006-medicare-payment-policy/</a>), MedPAC 
discussed the importance of appropriately valuing physicians'

[[Page 32376]]

services, stating that misvalued services can distort the market for 
physicians' services, as well as for other health care services that 
physicians order, such as hospital services. In that same report, 
MedPAC postulated that physicians' services under the PFS can become 
misvalued over time. MedPAC stated, ``When a new service is added to 
the physician fee schedule, it may be assigned a relatively high value 
because of the time, technical skill, and psychological stress that are 
often required to furnish that service. Over time, the work required 
for certain services would be expected to decline as physicians become 
more familiar with the service and more efficient in furnishing it.'' 
We believe services can also become overvalued when PE costs decline. 
This can happen when the costs of equipment and supplies fall, or when 
equipment is used more frequently than is estimated in the PE 
methodology, reducing its cost per use. Likewise, services can become 
undervalued when physician work increases, or PE costs rise.
    As MedPAC noted in its March 2009 Report to Congress (<a href="https://www.medpac.gov/docs/default-source/reports/march-2009-report-to-congress-medicare-payment-policy.pdf">https://www.medpac.gov/docs/default-source/reports/march-2009-report-to-congress-medicare-payment-policy.pdf</a>), in the intervening years since 
MedPAC made the initial recommendations, CMS and the RUC have taken 
several steps to improve the review process. Also, section 
1848(c)(2)(K)(ii) of the Act augments our efforts by directing the 
Secretary to specifically examine, as determined appropriate, 
potentially misvalued services in the following categories:
    <bullet> Codes that have experienced the fastest growth.
    <bullet> Codes that have experienced substantial changes in PE.
    <bullet> Codes that describe new technologies or services within an 
appropriate time-period (such as 3 years) after the relative values are 
initially established for such codes.
    <bullet> Codes which are multiple codes that are frequently billed 
in conjunction with furnishing a single service.
    <bullet> Codes with low relative values, particularly those that 
are often billed multiple times for a single treatment.
    <bullet> Codes that have not been subject to review since 
implementation of the fee schedule.
    <bullet> Codes that account for the majority of spending under the 
PFS.
    <bullet> Codes for services that have experienced a substantial 
change in the hospital length of stay or procedure time.
    <bullet> Codes for which there may be a change in the typical site 
of service since the code was last valued.
    <bullet> Codes for which there is a significant difference in 
payment for the same service between different sites of service.
    <bullet> Codes for which there may be anomalies in relative values 
within a family of codes.
    <bullet> Codes for services where there may be efficiencies when a 
service is furnished at the same time as other services.
    <bullet> Codes with high intraservice work per unit of time.
    <bullet> Codes with high PE RVUs.
    <bullet> Codes with high cost supplies.
    <bullet> Codes as determined appropriate by the Secretary.
    Section 1848(c)(2)(K)(iii) of the Act also specifies that the 
Secretary may use existing processes to receive recommendations on the 
review and appropriate adjustment of potentially misvalued services. In 
addition, the Secretary may conduct surveys, other data collection 
activities, studies, or other analyses, as the Secretary determines to 
be appropriate, to facilitate the review and appropriate adjustment of 
potentially misvalued services. This section also authorizes the use of 
analytic contractors to identify and analyze potentially misvalued 
codes, conduct surveys or collect data, and make recommendations on the 
review and appropriate adjustment of potentially misvalued services. 
Additionally, this section provides that the Secretary may coordinate 
the review and adjustment of any RVU with the periodic review described 
in section 1848(c)(2)(B) of the Act. Section 1848(c)(2)(K)(iii)(V) of 
the Act specifies that the Secretary may make appropriate coding 
revisions (including using current processes for consideration of 
coding changes), which may involve consolidating individual services 
into bundled codes for payment under the PFS.
2. Progress in Identifying and Reviewing Potentially Misvalued Codes
    To fulfill our statutory mandate, we have identified and reviewed 
numerous PMVC as specified in section 1848(c)(2)(K)(ii) of the Act, and 
we intend to continue our work examining PMVC in these areas over the 
upcoming years. As part of our current process, we identify PMVC for 
review, and request recommendations from the RUC and other public 
commenters on revised work RVUs and direct PE inputs for those codes. 
The RUC, through its own processes, also identifies PMVC for review. 
Through our public nomination process for PMVC established in the CY 
2012 PFS final rule with comment period (76 FR 73026, 73058 through 
73059), other individuals and groups submit nominations for review of 
PMVC as well. Individuals and groups may submit codes for review under 
the PMVC initiative to CMS in one of two ways. Nominations may be 
submitted to CMS via email or through postal mail. Email submissions 
should be sent to the CMS e-mailbox at 
<a href="/cdn-cgi/l/email-protection#0c416968656f6d7e695c64757f656f656d624a69695f6f6469687960694c6f617f2264647f226b637a"><span class="__cf_email__" data-cfemail="723f17161b11130017221a0b011b111b131c34171721111a1716071e1732111f015c1a1a015c151d04">[email&#160;protected]</span></a>, with the phrase ``Potentially 
Misvalued Codes'' and the referencing CPT code number(s) and/or the CPT 
descriptor(s) in the subject line. Physical letters for nominations 
should be sent via the U.S. Postal Service to the Centers for Medicare 
& Medicaid Services, Mail Stop: C4-01-26, 7500 Security Blvd, 
Baltimore, Maryland 21244. Envelopes containing the nomination letters 
must be labeled ``Attention: Division of Practitioner Services, 
Potentially Misvalued Codes.'' Nominations for consideration in our 
next annual rule cycle should be received by our February 10th 
deadline. Since CY 2009, as a part of the annual PMVC review and Five-
Year Review process, we have reviewed over 1,700 PMVC to refine work 
RVUs and direct PE inputs. We have assigned appropriate work RVUs and 
direct PE inputs for these services as a result of these reviews. A 
more detailed discussion of the extensive prior reviews of PMVC is 
included in the CY 2012 PFS final rule with comment period (76 FR 73052 
through 73055). In the same CY 2012 PFS final rule with comment period, 
we finalized our policy to consolidate the review of physician work and 
PE at the same time and established a process for the annual public 
nomination of potentially misvalued services.
    In the CY 2013 PFS final rule with comment period (77 FR 68892, 
68896 through 68897), we built upon the work we began in CY 2009 to 
review PMVC that have not been reviewed since the implementation of the 
PFS (so-called ``Harvard-valued codes'' \15\). In the CY 2009 PFS 
proposed rule (73 FR 38589), we requested recommendations from the RUC 
to aid in our review of Harvard-valued codes that had not yet been 
reviewed, focusing first on high-volume,

[[Page 32377]]

low intensity codes. In the fourth Five-Year Review of Work RVUs 
published in a separate notice (76 FR 32410, 32419), we requested 
recommendations from the RUC to aid in our review of Harvard-valued 
codes with annual utilization of greater than 30,000 services. In the 
CY 2013 PFS final rule with comment period, we identified specific 
Harvard-valued services with annual allowed charges that total at least 
$10,000,000 as potentially misvalued. In addition to the Harvard-valued 
codes, in the CY 2013 PFS final rule with comment period we finalized 
for review a list of PMVC that have stand-alone PE (codes with 
physician work and no listed work time and codes with no physician work 
that have listed work time). We continue each year to consider and 
finalize a list of PMVC that have or will be reviewed and revised as 
appropriate in future rulemaking.
---------------------------------------------------------------------------

    \15\ The research team and panels of experts at the Harvard 
School of Public Health developed the original work RVUs for most 
CPT codes, in a cooperative agreement with the Department of Health 
and Human Services (HHS). Experts from both inside and outside the 
Federal Government obtained input from numerous physician specialty 
groups. This input was incorporated into the initial PFS, which was 
implemented on January 1, 1992.
---------------------------------------------------------------------------

3. CY 2026 Identification and Review of Potentially Misvalued Services
    In the CY 2012 PFS final rule with comment period (76 FR 73058 
through 73059), we finalized a process for the public to nominate PMVC. 
In the CY 2015 PFS final rule with comment period (79 FR 67548, 67606 
through 67608), we modified this process whereby the public and 
interested parties may nominate PMVC for review by submitting the code 
with supporting documentation by February 10th of each year. Supporting 
documentation for codes nominated for the annual review of PMVC may 
include the following:
    <bullet> Documentation in peer reviewed medical literature or other 
reliable data that demonstrate changes in physician work due to one or 
more of the following: technique, knowledge and technology, patient 
population, site-of-service, length of hospital stay, and work time.
    <bullet> An anomalous relationship between the code being proposed 
for review and other codes.
    <bullet> Evidence that technology has changed physician work.
    <bullet> Analysis of other data on time and effort measures, such 
as operating room logs or national and other representative databases.
    <bullet> Evidence that incorrect assumptions were made in the 
previous valuation of the service, such as a misleading vignette, 
survey, or flawed crosswalk assumptions in a previous evaluation.
    <bullet> Prices for certain high cost supplies or other direct PE 
inputs that are used to determine PE RVUs are inaccurate and do not 
reflect current information.
    <bullet> Analyses of work time, work RVU, or direct PE inputs using 
other data sources (for example, VA, NSQIP, the STS National Database, 
and the MIPS data).
    <bullet> National surveys of work time and intensity from 
professional and management societies and organizations, such as 
hospital associations.
    We evaluate the supporting documentation submitted with the 
nominated codes and assess whether the nominated codes appear to be 
PMVC appropriate for review under the annual process. In the following 
year's PFS proposed rule, we publish the list of nominated codes and 
indicate for each nominated code whether we agree with its inclusion as 
a PMVC. The public has the opportunity to comment on these and all 
other proposed PMVC. In each year's final rule, we finalize our list of 
PMVC.
a. Public Nominations
    In each proposed rule, we seek nominations from the public and from 
interested parties of codes that they believe we should consider as 
potentially misvalued. We receive public nominations for PMVC by 
February 10th and we display these nominations on our public website 
(<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>?DLSort=2&DLEntries=10&DLPage=1&DLSortDir=descending), where we 
include the submitter's name, their associated organization and the 
submitted studies for full transparency. We sometimes receive 
submissions for specific, PE-related inputs for codes, and discuss 
these PE-related submissions, as necessary under the Determination of 
PE RVUs section of the rule. We summarize below this year's submissions 
under the PMVC initiative. For CY 2026, we received 11 requests 
concerning various codes as PMVC. The nominations are as follows:
    (1) Maxillofacial Prosthetic Services (CPT codes 21076, 21077, 
21079, 21080, 21081, 21082, 21083, 21084, 21085, 21086, 21087)
    An interested party nominated CPT codes 21076 (Impression and 
custom preparation; surgical obturator prosthesis), 21077 (Impression 
and custom preparation; orbital prosthesis), 21079 (Impression and 
custom preparation; interim obturator prosthesis), 21080 (Impression 
and custom preparation; definitive obturator prosthesis), 21081 
(Impression and custom preparation; mandibular resection prosthesis), 
21082 (Impression and custom preparation; palatal augmentation 
prosthesis), 21083 (Impression and custom preparation; palatal lift 
prosthesis), 21084 (Impression and custom preparation; speech aid 
prosthesis), 21085 (Impression and custom preparation; oral surgical 
splint), 21086 (Impression and custom preparation; auricular 
prosthesis), and 21087 (Impression and custom preparation; nasal 
prosthesis) as potentially misvalued based on what they believe to be 
missing, outdated, and undervalued practice expense inputs. The 
nominator stated that these misvalued PE inputs (equipment, supplies, 
and clinical staff time) result in inadequate payment rates to 
clinicians who furnish these services, which limits patient access to 
necessary care. The nominator indicated that the physician work values 
remain accurate for all of the nominated codes.
    According to the nominator, maxillofacial prosthodontists provide 
specialized rehabilitation care for patients with compromised oral and 
facial anatomy due to conditions such as cancer, trauma, or congenital 
defects, addressing both physical and psychological challenges 
experienced by such patients. Custom prosthetic obturators are medical 
devices that restore vital oral functions in cancer patients with 
palatal defects. These implant-retained devices are prescribed based on 
the location of the defect: maxillary obturators for hard palate 
issues, pharyngeal obturators for soft palate problems, or a 
combination for both. The primary purpose of the intraoral prostheses 
is to enable patients to speak, eat, and swallow more naturally. The 
nominator stated that these implants can improve patients' quality of 
life and may eliminate the need for feeding tubes.
    The nominator is concerned that CMS payment rates for maxillofacial 
prosthetic services, which were last reviewed in 1995, are outdated. In 
particular, the nominator stated that CPT codes 21080 and 21081 have 
undergone significant changes since the development of their PE values 
in the mid-1990s. At that time, mandibular reconstruction was rare, and 
removable prostheses were used to align the jaw. Microvascular 
reconstruction and virtual surgical planning have since transformed the 
procedures described by CPT codes 21080 and 21081, allowing precise 
prosthetic rehabilitation during surgery and improving oral function, 
speech, and quality of life. The nominator asserted that the PE inputs 
for CPT codes 21080 and 21081 did not account for these advancements, 
which did not exist in 1995 when the codes were valued. Furthermore, 
they stated that when these maxillofacial prosthetic services

[[Page 32378]]

were valued in 1995, CMS used inaccurate inputs, which they believe did 
not account for the appropriate clinical staff time and materials 
required for prostheses. They stated that changes in clinical staff 
time, supplies, and equipment require the direct PE inputs to be 
updated.
    The nominator stated that significant technological advancements 
have also occurred for extraoral prostheses, such as orbital (CPT code 
21077), auricular (CPT code 21086), and nasal prostheses (CPT code 
21087). For orbital prostheses, hand sculpting and painting remain 
time-intensive tasks, with limited use of 3D technology. In auricular 
prostheses, 3D technology has significantly improved the waxing 
process. For nasal prostheses, preoperative scanning now helps to shape 
the prosthesis, leading to better cosmetic outcomes. All extraoral 
prostheses (for example, orbital, auricular, and nasal) now commonly 
use 3D technology, craniofacial implants, and color-matching devices, 
which were not standard in the 1990s. The nominator asserted that the 
practice expense inputs for these codes fail to account for these 
advancements.
    Additionally, the nominator asserts that there are other instances 
where the nominated codes fail to reflect the significant technological 
advancements in treatment delivery since 1995. The nominator requested 
an update to the PE inputs for all of the nominated codes, stating that 
the dental x-ray (ER071), valued at $128,020.91, has been replaced by 
various pieces of capital equipment. For example, they listed a ``CMS 
Planmeca CBCT Imaging'' system, which costs $163,767.66, and stated 
that this takes the place of the x-ray unit, highlighting a notable 
price difference between the x-ray machine and the CT. Furthermore, 
they provided a lengthy list of additional equipment (e.g., 3D printer) 
that is not accounted for in the PE inputs for all of the nominated 
codes, underscoring the extensive modernization in service delivery 
since 1995.
    To support their nomination, the nominator included information on 
what they believe to be more accurate PE inputs, including invoices for 
supplies and equipment. For items where invoices paid were unavailable, 
price quotes from a supplier were included. In addition, their 
appendices included recommendations for deleting and adding supplies, 
equipment, and clinical staff time. For more information, we refer 
readers to the submitted nomination, which is posted in the public use 
files for this proposed rule available on our public website under PFS 
Federal Regulation Notices 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>.
    Although the nomination stated that the work RVUs are accurate as 
currently valued, because these codes have not been reviewed in the 
last 30 years, we believe it is appropriate to examine both PE and work 
inputs. Given the technological advancements the nominator described, 
there may also be resulting changes in the physician work involved in 
performing these services, and therefore, a comprehensive review of 
both practice expense and work values would be appropriate. While we 
are not proposing to nominate these codes as potentially misvalued, we 
welcome public comments and recommendations, including those from the 
RUC, to better understand these codes, particularly regarding typical 
direct PE inputs and work values.
    (2) Supervision of Preparation and Provision of Antigens for 
Allergen Immunotherapy (CPT codes 95145, 95146, 95147, 95148, 95149).
    An interested party nominated the professional supervision of 
preparation and provision of stinging insect venom for allergen 
immunotherapy described by CPT codes 95145 (Professional services for 
the supervision of preparation and provision of antigens for allergen 
immunotherapy (specify number of doses); single stinging insect venom), 
95146 (Professional services for the supervision of preparation and 
provision of antigens for allergen immunotherapy (specify number of 
doses); 2 single stinging insect venoms), 95147 (Professional services 
for the supervision of preparation and provision of antigens for 
allergen immunotherapy (specify number of doses); 3 single stinging 
insect venoms), 95148 (Professional services for the supervision of 
preparation and provision of antigens for allergen immunotherapy 
(specify number of doses); 4 single stinging insect venoms), and 95149 
(Professional services for the supervision of preparation and provision 
of antigens for allergen immunotherapy (specify number of doses); 5 
single stinging insect venoms) as potentially misvalued, stating that 
the current payment rates for these CPT codes do not accurately reflect 
the practice expenses required for these procedures. The nominator 
indicated that the cost to manufacture venom therapy has drastically 
increased since the last time these codes were reviewed by the RUC in 
2001, citing higher labor and raw material costs.
    Venom immunotherapy, used for treating insect stings, involves 
extracting venom from various stinging insects like honeybees and 
wasps. According to the nominator, the manufacturing process is labor-
intensive, requiring 520 staff hours to manually extract venom from 
130,000 insects per batch, along with substantial equipment investment. 
The final product is packaged in single, five, or twelve-dose vials for 
medical use. For more information, we refer readers to the submitted 
nomination, which is posted in the public use files for this proposed 
rule available on our public website under PFS Federal Regulation 
Notices 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>.
    The nominator stated that before 1995, venom products were paid 
under product-specific HCPCS J-codes, but due to infrequent use and 
limited budget impact on the Medicare trust funds, CMS retired the J-
codes and instead bundled venom products within CPT codes 95145, 95146, 
95147, 95148, and 95149. According to the nominator, current payment 
rates for these codes are based on the Harvard valuation and have not 
been surveyed by the RUC since February 2001. The nominator stated that 
when surveyed in 2001, the PE inputs for these codes only accounted for 
swab-pad, antigen, syringe, and gloves. In contrast, the nominator 
indicated that CPT code 95165 (Professional services for the 
supervision of preparation and provision of antigens for allergen 
immunotherapy; single or multiple antigens (specify number of doses), 
which was more recently reviewed in 2016 and shares similar PE inputs 
as the nominated codes, includes additional items such as a surgical 
cap, gown, mask, alcohol, paper towel, and vial transport envelope. The 
nominator stated that, according to the 2019 standards for allergen 
extract compounding under USP Chapter 797,\16\ the procedures described 
by CPT codes 95145, 95146, 95147, 95148, and 95149 require additional 
supplies and practice expenses, such as sterile powder-free gloves, 
face mask, hair net/beard net, gown/sterile garb, isopropyl alcohol, 
paper towel, sterile empty vials, and albumin saline, in addition to 
the allergenic extract. The nominator stated that these standards also 
mandate significantly more annual training for providers, including 
competency observation, media fill test, gloved fingertip test, and 
corrective actions. Furthermore, the nominator asserted

[[Page 32379]]

that the overall cost of venom therapy has increased substantially and 
submitted invoices to support this statement.

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

    At this time, we are not proposing the CPT codes submitted by the 
nominator as potentially misvalued. CPT codes 95145-95149 are typically 
billed in conjunction with CPT codes 95115 and 95117. We note that the 
nominator has listed PE inputs that are also included in the inputs for 
CPT codes 95115 and 95117 and these same inputs may overlap with inputs 
included in CPT codes 95145-95149. While the PE inputs that overlap 
between CPT codes 95145-95149 and 95115 and 95117 may contain the 
necessary elements, we are seeking feedback regarding these overlapping 
PE inputs in relation to billing frequencies and the possibility of 
duplicative payment. Specifically, we request comments on whether these 
inputs overlap and what potential adjustments should be made to avoid 
duplicative payment. We request comments regarding the standard minutes 
for clinical activity code CA008 (Perform regulatory mandated quality 
assurance activity (pre-service)) and the standard unit measurement for 
supply code SH004 (albumin saline). Additionally, we seek input 
regarding the establishment of clinical activity codes for two specific 
procedures requested by the nominator: cleaning and disinfecting the 
compounding area, and sterile preparation of compounds.
    Furthermore, anomalies were identified related to the clinical 
activities described by CA021 (Perform procedure/service--NOT directly 
related to physician work time). Specifically, the typical times 
associated with these activities in the RUC database are as follows: 
2.3 minutes for CPT code 95145, 3.3 minutes for CPT code 95146, 2.3 
minutes for CPT code 95147, 3.3 minutes for CPT code 95148, and 4.3 
minutes for CPT code 95149. The nominator has requested 10 minutes for 
all of the nominated CPT codes without providing any justification for 
this time. Regarding the clinical labor direct inputs (L037D), we seek 
comments on several aspects of dosage preparation, including but not 
limited to: the typical number of dosages, the time required for 
preparation, the number of vials or dosages that can be prepared from 
each vial, and the total time needed for preparation of these vials and 
dosages. Additionally, we seek information about the derivation of the 
2.3-minute time. This information would help inform the appropriate 
time for both clinical labor activities.
    We received several invoices for mixed and single venom prices from 
the nominator; however, we are unable to determine the number of 
individual venoms in the mixed venom preparations. Specifically, supply 
codes SH009 (antigen, venom) and SH010 (antigen, venom, tri-vespid) are 
currently priced at $35.58 and $69.21 respectively, with prices last 
updated in the CY 2024 PFS final rule (88 FR 78967). The nominator 
stated that the venom cost has increased to $481.50 for a 5-dose wasp 
venom as of April 1, 2024, and submitted invoices to support this claim 
to update the current price. Since we are unsure whether these invoices 
are for mixed or single venom prices, we welcome additional invoices 
and comments regarding the methodology for calculating venom prices 
using mixture invoices. We welcome feedback to gain a broader 
understanding of these codes, including how standards of practice have 
evolved over time, as this information can help identify related coding 
issues.
    (3) Electronic analysis of implanted neurostimulator pulse 
generator/transmitter (CPT codes 95970, 95976, 95977).
    CPT codes 95970 (Electronic analysis of implanted neurostimulator 
pulse generator/transmitter (eg, contact group[s], interleaving, 
amplitude, pulse width, frequency [Hz], on/off cycling, burst, magnet 
mode, dose lockout, patient selectable parameters, responsive 
neurostimulation, detection algorithms, closed loop parameters, and 
passive parameters) by physician or other qualified health care 
professional; with brain, cranial nerve, spinal cord, peripheral nerve, 
or sacral nerve, neurostimulator pulse generator/transmitter, without 
programming), 95976 (Electronic analysis of implanted neurostimulator 
pulse generator/transmitter (eg, contact group[s], interleaving, 
amplitude, pulse width, frequency [Hz], on/off cycling, burst, magnet 
mode, dose lockout, patient selectable parameters, responsive 
neurostimulation, detection algorithms, closed loop parameters, and 
passive parameters) by physician or other qualified health care 
professional; with simple cranial nerve neurostimulator pulse 
generator/transmitter programming by physician or other qualified 
health care professional), and 95977 (Electronic analysis of implanted 
neurostimulator pulse generator/transmitter (eg, contact group[s], 
interleaving, amplitude, pulse width, frequency [Hz], on/off cycling, 
burst, magnet mode, dose lockout, patient selectable parameters, 
responsive neurostimulation, detection algorithms, closed loop 
parameters, and passive parameters) by physician or other qualified 
health care professional; with complex cranial nerve neurostimulator 
pulse generator/transmitter programming by physician or other qualified 
health care professional) were nominated as potentially misvalued for 
two reasons identified by the nominator: there has been a significant 
shift in the clinical specialties utilizing these codes, and the PE 
inputs currently assigned to these codes may not accurately reflect the 
costs associated with analyzing and programming the hypoglossal nerve 
stimulation (HGNS) system.
    The nominator stated that, from 2017 to 2023, there has been a 
significant change in the clinical specialties that utilize these codes 
in the non-facility setting. According to the nominator, while CPT 
codes 95970, 95976, and 95977 were primarily billed by neurologists 
when last surveyed by the RUC in 2017, the usage of these codes has 
shifted away from neurologists toward sleep specialists. The nominator 
asserted that this shift necessitates changes to the work RVUs and PE 
inputs for these codes. In addition, the nominator stated that many 
sleep specialists believe CPT codes 95970, 95976, and 95977 do not 
appropriately reflect the practice expenses involved in furnishing 
these services. According to the nominator, a survey conducted among 
several high-volume sleep specialists (the details of which the 
nominator did not share with CMS) showed unanimous agreement that these 
codes do not accurately reflect the practice expense inputs. These 
three codes currently have 0 minutes of clinical staff time included in 
the direct PE inputs. However, the nominator stated that based on the 
survey results the typical clinical staff time spent for patient care 
was 35 minutes for CPT code 95970, 37 minutes for CPT code 95976, and 
46 minutes for CPT code 95977. The nominator stated that CPT codes 
95970, 95976, and 95977 should reflect the same clinical staff time as 
similar analysis and programming procedures, such as CPT codes 93150 
(Therapy activation of implanted phrenic nerve stimulator system, 
including all interrogation and programming), 93151 (Interrogation and 
programming (minimum one parameter) of implanted phrenic nerve 
stimulator system), and 93153 (Interrogation without programming of 
implanted phrenic nerve stimulator system). The nominator stated that 
these codes more accurately account for the clinical staff time.
    We appreciate the nominator sharing their survey results from high-
volume

[[Page 32380]]

sleep specialists, which may indicate potential inaccuracies in the 
direct PE inputs for CPT codes 95970, 95976, and 95977. Our review of 
the submitted information, however, reveals a lack of survey details 
(for example, sampling methods, data collection procedures), so it is 
difficult to understand the context of the information provided by the 
nominator and identify potential biases of this survey. While we 
acknowledge potential changes in the specialties utilizing these codes, 
and sleep medicine's Medicare specialty percentage has grown over time, 
neurology remains the dominant billing practitioner type. For these 
reasons, we are not proposing to consider these codes as potentially 
misvalued. We are, however, seeking comments and additional information 
on the information provided by the nominator. This includes any 
analysis or studies demonstrating that one or more of these codes meet 
the criteria listed in section II.C.3 of this proposed rule, under 
``Identification and Review of Potential Misvalued Services,'' 
particularly regarding changes in practice expense inputs for service 
delivery.
    (4) Excimer laser treatment for psoriasis (CPT codes 96920, 96921, 
96922).
    An interested party nominated CPT codes 96920 (Excimer laser 
treatment for psoriasis; total area less than 250 sq cm), 96921 
(Excimer laser treatment for psoriasis; 250 sq cm to 500 sq cm), and 
96922 (Excimer laser treatment for psoriasis; over 500 sq cm) as 
potentially misvalued, due to the CPT Editorial Panel's recent 
modifications to the code descriptor and allegedly inaccurate data used 
by CMS in valuing these services.
    According to the nominator, the misvaluation of these codes creates 
a significant healthcare access barrier by reducing payment for excimer 
laser therapy, which disproportionately impacts vulnerable populations 
while potentially increasing overall healthcare costs. The nominator 
stated that the low payment rates for these codes make it financially 
unfeasible for dermatologists to offer this FDA-approved treatment, 
effectively making it unavailable to Medicare beneficiaries despite its 
proven effectiveness and potential cost savings.
    We discussed our review of these codes and our rationale for 
finalizing the current work RVUs and direct PE extensively in the CY 
2025 PFS final rule (89 FR 97797 through 97801). We stated that we 
disagreed with the RUC recommended work RVUs for CPT codes 96920, 
96921, and 96922 of 1.00, 1.07, and 1.32. The RUC noted that there have 
been multiple reviews of these CPT codes, and the valuation of the 
codes is currently based on the original valuation over two decades ago 
in 2002 where the physician time values were lower than the current 
times. A subsequent review in 2012 adopted new survey times while 
maintaining the work RVUs from 2002 for CPT codes 96920 and 96922. The 
RUC noted that for both CPT code 96921 and 96922, with the largest 
treatment area, the total times had not changed since first implemented 
more than 20 years ago. At the time we also believed that, since the 
two components of work are time and intensity, absent an obvious or 
explicitly stated rationale for why the relative intensity of a given 
procedure had increased, significant decreases in time should be 
reflected in decreases to work RVUs. We noted that our proposed work 
RVU of 0.83 maintained the intensity associated with the 2002 review of 
CPT code 96920, which we believed to be more appropriate than the 
significant increase in intensity that results from the RUC-recommended 
work RVU of 1.00 which nearly doubled the current intensity of the code 
(89 FR 97797). We had no evidence to indicate that the intensity of CPT 
code 96920 had increased to this degree given how the surveyed work 
time had substantially decreased.
    For CY 2026, the nominator raised two issues related to these 
codes. First, according to the nominator, a coding change by the CPT 
Editorial Panel that was released in 2024 and effective January 1, 
2025, modified the code descriptor from ``Laser treatment for 
inflammatory skin disease(psoriasis)'' to ``Excimer laser treatment for 
psoriasis.'' We remind readers that, in April 2022, the RUC referred 
CPT codes 96920, 96921, and 96922 to the CPT Editorial Panel to capture 
expanded indications beyond what was currently noted in the codes' 
descriptions to include laser treatment for other inflammatory skin 
disorders such as vitiligo, atopic dermatitis, and alopecia areata, and 
those expanded indications could reflect changes in physician work as 
compared to the codes' current descriptors. The coding change 
application was subsequently withdrawn from the September 2022 CPT 
Editorial Panel meeting when it was determined that existing literature 
was insufficient and did not support expanded indications at that time. 
Therefore, these CPT codes were re-surveyed and reviewed at the April 
2023 RUC meeting without any revisions to their code descriptors. We 
note that, according to the CPT Editorial Panel and the RUC's publicly 
available meeting notes, since the descriptors for CPT codes 96920, 
96921, and 96922 were established in 2002, psoriasis is the only 
approved indication and use for this treatment modality.\17\

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

     While the nominator is working with the CPT Editorial Panel again 
to expand the indications for excimer laser treatment beyond psoriasis 
to include other inflammatory skin conditions, they stated that they 
believe establishing a temporary G-code for interim coverage is 
necessary and therefore requested that CMS create coding to more 
accurately reflect the clinically appropriate use of the excimer laser. 
The nominator states that this would ensure patients with skin 
conditions other than psoriasis can access excimer laser treatments 
without delay.
    To provide more evidence as to the accuracy of including non-
psoriasis inflammatory skin diseases in the code definition, the 
nominator provided a data compendium supporting the excimer laser's 
versatility and key studies demonstrating positive outcomes for 
conditions like vitiligo, atopic dermatitis, leukoderma, and alopecia 
areata. Reviewing these submitted studies, the nominator stated that 
sufficient clinical evidence exists to support expanding coverage for 
excimer laser treatment beyond just psoriasis. The nominator requested 
that CMS create additional coding to describe the expanded indications 
for the excimer laser treatment, because the nominator believes that 
the standard CPT process is time-consuming and could leave many 
patients without adequate care in the interim; thus, implementing a 
temporary G-code would ensure continued access to this essential 
therapy for these patients.
    Second, the nominator provided additional invoices and data 
detailing PE costs related to the excimer laser devices. The nominator 
claimed that their own analysis relies on real-world data (which was 
not shared with CMS) and shows that CMS has overestimated the 
utilization rate of excimer lasers. Using their own survey, they found 
that on average, dermatologists perform 244 excimer laser treatments 
per device annually, with each treatment requiring approximately 38 to 
46 minutes of excimer laser use. This amounts to nearly 15,000 minutes 
of total utilization per year, resulting in an effective utilization 
rate of 10 percent, rather than the 50 percent rate currently used by 
CMS. As stated in section II.B. of this proposed rule, we currently use 
an equipment utilization rate

[[Page 32381]]

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.
    Based on their real-world device utilization data, the nominator 
calculated the direct PE cost using CMS' standard equipment formula. 
The calculated equipment costs are $99.88 for CPT code 96920, $105.14 
for CPT code 96921, and $120.91 for CPT code 96922. The nominator also 
stated that CMS currently assumes a maintenance cost of $7,560 for 
excimer lasers, based on a 5% maintenance rate applied to a purchase 
price of $151,200. However, the nominator stated that excimer lasers 
are technical devices with substantially higher maintenance costs. 
According to the nominator, the annual service cost for the excimer 
laser is $30,000, and they claimed that a laser chamber replacement 
service costs $44,000; however, as discussed in section II.B. of this 
proposed rule, we finalized a 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 stated that this estimate 
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. 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, 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. Therefore, we remind readers that we do not believe voluntary 
submissions regarding the maintenance costs of individual equipment 
items would be an appropriate methodology for determining costs.
    Moreover, the nominator asserted that CMS currently does not 
include the costs of consumable gas (code EQ154) and the optical 
delivery system (code EQ155) in the direct practice expense cost for 
these services. Based on our review of the January 2012 RUC 
recommendations submitted to CMS, it appears that these equipment items 
were removed by RUC PE Subcommittee for CY 2013. The requestor stated 
that the gas cylinder (EQ154) costs $6,300 (excluding labor and 
shipping costs), and the optical delivery system (EQ155) costs $7,429; 
however, no supporting invoices or evidence of the typicality of the 
equipment items' usage for these services were provided to support the 
equipment items' reintegration into the codes' direct practice expense.
    Based on this information, the nominator recommended creating a G-
code for excimer laser treatment of inflammatory skin diseases. 
Furthermore, they requested to include their own real-world data on 
excimer laser utilization rates in the practice expense calculation, 
adjust the maintenance cost in the practice expense calculation to 
reflect the actual cost of maintaining excimer laser devices, and 
reinstate the costs of consumable gas (code EQ154) and the optical 
delivery system (code EQ155) in the practice expense calculation.
    We appreciate the detailed information submitted by the nominator. 
However, we continue to disagree that CPT codes 96920, 96921, and 96922 
are potentially misvalued. We note that the CPT code change request was 
withdrawn from the AMA in September 2022 due to insufficient supporting 
literature for expanded indications. Additionally, according to RUC's 
publicly available meeting notes, psoriasis is the only approved 
indication and use for this treatment modality since the descriptors 
for CPT codes 96920, 96921, and 96922 were established in 2002. When
