Abstract

This proposed rule would revise the Medicare Hospital Outpatient Prospective Payment System (OPPS) and the Medicare Ambulatory Surgical Center (ASC) payment system for calendar year 2026 based on our continuing experience with these systems. We also describe the changes to the amounts and factors used to determine the payment rates for Medicare services paid under the OPPS and those paid under the ASC payment systems. This proposed rule would also update and refine the requirements for the Hospital Outpatient Quality Reporting Program, Rural Emergency Hospital Quality Reporting Program, Ambulatory Surgical Center Quality Reporting Program, Overall Hospital Quality Star Rating, and hospitals to make public their standard charge information and enforcement of hospital price transparency. This rule also contains requests for information on measure concepts regarding Well-Being and Nutrition for consideration in future years for all three programs (OQR, REHQR, and ASCQR; expanding the method to control for unnecessary increases in the volume of covered OPD services to on- campus clinic visits; software as a service; and adjusting payment under the OPPS for services predominately performed in the ambulatory surgical center or physician office settings.

Price Transparency

AGENCY: Centers for Medicare & Medicaid Services (CMS), Department of 
Health and Human Services (HHS).

ACTION: Proposed rule.

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

SUMMARY: This proposed rule would revise the Medicare Hospital 
Outpatient Prospective Payment System (OPPS) and the Medicare 
Ambulatory Surgical Center (ASC) payment system for calendar year 2026 
based on our continuing experience with these systems. We also describe 
the changes to the amounts and factors used to determine the payment 
rates for Medicare services paid under the OPPS and those paid under 
the ASC payment systems. This proposed rule would also update and 
refine the requirements for the Hospital Outpatient Quality Reporting 
Program, Rural Emergency Hospital Quality Reporting Program, Ambulatory 
Surgical Center Quality Reporting Program, Overall Hospital Quality 
Star Rating, and hospitals to make public their standard charge 
information and enforcement of hospital price transparency. This rule 
also contains requests for information on measure concepts regarding 
Well-Being and Nutrition for consideration in future years for all 
three programs (OQR, REHQR, and ASCQR; expanding the method to control 
for unnecessary increases in the volume of covered OPD services to on-
campus clinic visits; software as a service; and adjusting payment 
under the OPPS for services predominately performed in the ambulatory 
surgical center or physician office settings.

I. Summary and Background

A. Executive Summary of this Document

1. Purpose
    We propose to update the payment policies and payment rates for 
services furnished to Medicare beneficiaries in hospital outpatient 
departments (HOPDs) and ambulatory surgical centers (ASCs), beginning 
January 1, 2026. Section 1833(t) of the Social Security Act (the Act) 
requires us to annually review and update the payment rates for 
services payable under the Hospital Outpatient Prospective Payment 
System (OPPS). Specifically, section 1833(t)(9)(A) of the Act requires 
the Secretary of the Department of Health and Human Services (the 
Secretary) to review certain components of the OPPS not less often than 
annually, and to revise the groups, the relative payment weights, and 
the wage and other adjustments to take into account changes in medical 
practice, changes in technology, and the addition of new services, new 
cost data, and other relevant information and factors. In addition, 
under section 1833(i)(D)(v) of the Act, we annually review and update 
the ASC payment rates. This proposed rule also includes additional 
policy changes made in accordance with our experience with the OPPS and 
the ASC payment system and recent changes in our statutory authority. 
We describe these and various other statutory authorities in the 
relevant sections of this proposed rule. In addition, this proposed 
rule would update the requirements for the Hospital Outpatient Quality 
Reporting (OQR), the Rural Emergency Hospital Quality Reporting 
(REHQR), the Ambulatory Surgical Center Quality Reporting (ASCQR) 
Programs, and Overall Hospital Quality Star Rating. Finally, we would 
also update and refine the requirements for hospitals to make public 
their standard charges and CMS enforcement of hospital price 
transparency (HPT) regulations.
    Please note, some sections of this proposed rule contain a request 
for information (RFI). In accordance with the implementing regulations 
of the Paperwork Reduction Act of 1995 (PRA), specifically 5 CFR 
1320.3(h)(4), these general solicitations are exempt from the PRA. 
Facts or opinions submitted in response to general solicitations of 
comments from the public, published in the Federal Register or other 
publications, regardless of the form or format thereof, provided that 
no person is required to supply specific information pertaining to the 
commenter, other than that necessary for self-identification, as a 
condition of the agency's full consideration, are not generally 
considered information collections and therefore not subject to the 
PRA.
    Respondents are encouraged to provide complete but concise 
responses. These RFIs are issued solely for information and planning 
purposes; they do not constitute a Request for Proposal (RFP), 
applications, proposal abstracts, or quotations. These RFIs do not 
commit the U.S. Government to contract for any supplies or services or 
make a grant award. Further, CMS is not seeking proposals through these 
RFIs and will not accept unsolicited proposals. Responders are advised 
that the U.S. Government will not pay for any information or 
administrative costs incurred in response to these RFIs; all costs 
associated with responding to these RFIs will be solely at the 
interested party's expense. Not responding to these RFIs does not 
preclude participation in any future procurement, if conducted. It is 
the responsibility of the potential responders to monitor these RFI 
announcements for additional information pertaining to these requests.
    Please note that CMS will not respond to questions about the policy 
issues raised in these RFIs. CMS may or may not choose to contact 
individual responders. Such communications would only serve to further 
clarify written responses. Contractor support personnel may be used to 
review RFI responses. Responses to this notice are not offers and 
cannot be accepted by the U.S. Government to form a binding contract or 
issue a grant. Information obtained as a result of these RFIs may be 
used by the U.S. Government for program planning on a non-attribution 
basis. Respondents should not include any information that might be 
considered proprietary or confidential. These RFIs should not be 
construed as a commitment or authorization to incur cost for which 
reimbursement would be required or sought. All submissions become U.S. 
Government property and will not be returned. CMS may publicly post the 
comments received, or a summary thereof.
2. Summary of the Major Provisions
    <bullet> OPPS Update: For CY 2026, we propose to increase the 
payment rates under the OPPS by an Outpatient Department (OPD) fee 
schedule increase factor of 2.4 percent. This increase factor is based 
on the proposed inpatient hospital market basket percentage increase of 
3.2 percent for inpatient services paid under the hospital inpatient 
prospective payment system (IPPS) reduced by a proposed productivity 
adjustment of 0.8 percentage point. Based on this update, we estimate 
that total payments to OPPS providers (including beneficiary cost 
sharing and estimated changes in enrollment, utilization, and case mix) 
for calendar year (CY) 2026 will be approximately $100.0 billion, an 
increase of approximately $8.1 billion compared to estimated CY 2025 
OPPS payments.
    We are continuing to implement the statutory 2.0 percentage point 
reduction in payments for hospitals that fail to meet the hospital 
outpatient quality reporting requirements by applying a reporting 
factor of 0.9805 to the OPPS payments and copayments for all applicable 
services. We note that under the proposed 340B remedy offset, payments 
for services at hospitals subject to the 340B remedy offset will be 
reduced by 2.0 percentage points.
    <bullet> ASC Payment Update: For CYs 2019 through 2023, we adopted 
a policy to update the ASC payment system using the hospital market 
basket update. In light of the impact of the COVID-19 public health 
emergency (PHE) on healthcare utilization, we extended our policy to 
update the ASC payment system using the hospital market basket update 
an additional 2 years--through CYs 2024 and 2025. In this proposed 
rule, we propose to extend our utilization of the hospital market 
basket update as the update factor for the ASC payment system for 1 
additional year (through CY 2026). Using the hospital market basket 
update, for CY 2026, we propose to increase payment rates under the ASC 
payment system by 2.4 percent for ASCs that meet the quality reporting 
requirements under the ASCQR Program. This increase is based on a 
proposed hospital market basket percentage increase of 3.2 percent 
reduced by a proposed productivity adjustment of 0.8 percentage point. 
Based on this proposed update, we estimate that total payments to ASCs 
(including beneficiary cost sharing and estimated changes in 
enrollment, utilization, and case-mix) for CY 2026 will be 
approximately $9.2 billion, an increase of approximately $480 million 
compared to estimated CY 2025 Medicare payments.
    <bullet> Device Pass-Through Payment Applications: For CY 2026, we 
received 7 complete applications for device pass-through payments. We 
solicit public comment on these applications and will make final 
determinations on these applications in the CY 2026 OPPS/ASC final rule 
with comment period.
    <bullet> Changes to the List of ASC Covered Surgical Procedures and 
Ancillary

[[Page 33480]]

Services Lists: For CY 2026, we propose to expand the ASC CPL by 
revising the criteria under Sec.  416.166 to modify the general 
standard criteria and to eliminate five of the general exclusion 
criteria, moving them into a new section as nonbinding physician 
considerations for patient safety. We also propose to add 276 
procedures to the ASC CPL based on these criteria changes and add an 
additional 271 codes to the ASC CPL that are proposed for removal from 
the IPO list for CY 2026.
    <bullet> Changes to the Inpatient Only (IPO) List: For CY 2026, we 
propose to phase out the IPO list over 3 years, beginning with the 
removal of 285 mostly musculoskeletal services for CY 2026.
    <bullet> Add-on Payment for Radiopharmaceutical Technetium-99m (Tc-
99m) Derived from Domestically Produced Molybdenum-99 (Mo-99): In the 
CY 2025 OPPS/ASC final rule with comment period, we finalized that for 
CY 2026 the add-on payment for radiopharmaceuticals produced without 
the use of Tc-99m derived from non-Highly Enriched Uranium sources 
would be replaced with an add-on payment for radiopharmaceuticals that 
use Tc-99m derived from domestically produced Mo-99. For CY 2026, we 
propose a $10 per dose amount for this add-on payment, and that at 
least 50 percent of the Mo-99 used in the Tc-99m generator that 
produces a dose of Tc-99m must be domestically produced for the dose to 
qualify for the add-on payment. We also propose to codify our 
definition for domestically produced Mo-99, and to establish new HCPCS 
C-code C917X (Tc-99m from domestically produced non-HEU Mo-99, [minimum 
50 percent], full cost recovery add-on, per study dose).
    <bullet> Cross-Program Proposals for the Hospital Outpatient 
Quality Reporting (OQR), Rural Emergency Hospital Quality Reporting 
(REHQR), and Ambulatory Surgical Center Quality Reporting (ASCQR) 
Programs: We propose to remove: (1) the COVID-19 Vaccination Coverage 
Among Healthcare Personnel (HCP) measure from the Hospital OQR and 
ASCQR Program measure sets beginning with the CY 2024 reporting period/
CY 2026 payment determination; (2) the Hospital Commitment to Health 
Equity (HCHE) measure from the Hospital OQR and REHQR Program measure 
sets and the Facility Commitment to Health Equity (FCHE) measure from 
the ASCQR Program measure set beginning with the CY 2025 reporting 
period/CY 2027 payment or program determination; and (3) the Screening 
for Social Drivers of Health (SDOH) measure and the Screen Positive 
Rate for SDOH measure from the Hospital OQR, REHQR, and ASCQR Program 
measure sets beginning with the CY 2025 reporting period. Additionally, 
we seek comments regarding measured concepts related to well-being and 
nutrition for future consideration in the Hospital OQR, REHQR, and 
ASCQR Programs. We also propose to update and codify the Extraordinary 
Circumstance Exception (ECE) policy to clarify that CMS has the 
discretion to grant an extension in response to an ECE request for the 
Hospital OQR, REHQR, and ASCQR Programs.
    <bullet> Hospital Outpatient Quality Reporting (OQR) Program: In 
addition to the cross-program measures and policies, we propose to: (1) 
adopt the Emergency Care Access & Timeliness eCQM with one year of 
voluntary reporting for the CY 2027 reporting period followed by 
mandatory reporting for the CY 2028 reporting period/CY 2030 payment 
determination and subsequent years; (2) remove the Median Time from 
Emergency Department (ED) Arrival to ED Departure for Discharged ED 
Patients and the Left Without Being Seen measures beginning with the CY 
2028 reporting period/2030 payment determination, contingent upon 
finalization of adoption of the Emergency Care Access and Timeliness 
eCQM; and (3) modify the Excessive Radiation Dose or Inadequate Image 
Quality for Diagnostic Computed Tomography (CT) in Adults (Hospital 
Level--Outpatient) measure (Excessive Radiation eCQM) from mandatory 
reporting beginning with the CY 2027 reporting period to continue 
voluntary reporting in the CY 2027 reporting period and subsequent 
years.
    <bullet> Rural Emergency Hospital Quality Reporting (REHQR) 
Program: In addition to the cross-program measures and policies, we 
propose to: (1) adopt the Emergency Care Access & Timeliness eCQM 
beginning with the CY 2027 reporting period/CY 2029 program 
determination; and (2) establish related eCQM data submission and 
reporting requirements, including that REHs would be provided the 
option of reporting either the Emergency Care Access and Timeliness 
eCQM or the Median Time from Emergency Department (ED) Arrival to ED 
Departure for Discharged ED Patients measure beginning with the CY 2027 
reporting period/CY 2029 program determination.
    <bullet> Ambulatory Surgical Center Quality Reporting (ASCQR) 
Program: In addition to the cross-program measures and policies, we 
propose to: (1) adopt the Patient Understanding of Key Information 
Related to Recovery After a Facility-Based Outpatient Procedure or 
Surgery, Patient Reported Outcome-Based Performance Measure 
(Information Transfer PRO-PM) beginning with voluntary reporting for 
the CY 2027 and CY 2028 reporting periods followed by mandatory 
reporting beginning with the CY 2029 reporting period/CY 2031 payment 
determination.
    <bullet> Overall Hospital Quality Star Rating Modification to 
Emphasize the Safety of Care Measure Group: We propose updating the 
methodology that will be used to calculate the Overall Hospital Quality 
Star Rating through implementation of a 2-stage methodologic update. We 
are updating the methodology to emphasize the importance of the Safety 
of Care measure group, particularly to address the issue of hospitals 
receiving a high Star Rating despite performing in the lowest quartile 
of the Safety of Care measure group. The first-stage methodology update 
would be a narrow but focused transitional step that would limit 
hospitals to a maximum of four out of five stars (based on at least 
three Safety of Care measure scores) if they performed in the lowest 
quartile of the Safety of Care measure group in the 2026 Overall 
Hospital Quality Star Rating. The second stage of the methodology 
update would replace the first-stage update and reduce the Star Rating 
of any hospital in the lowest quartile of Safety of Care (based on at 
least three Safety of Care measure scores) by one star, to a minimum 1-
star rating for the 2027 Overall Hospital Quality Star Rating and later 
years. These changes will prioritize safety for both patients and 
healthcare workers and reflect CMS' fundamental commitment to ensuring 
high-quality, safe care as a central component of health system 
performance.
    <bullet<ls-thn-eq> Partial Hospitalization and Intensive 
Outpatient: We propose to calculate the CY 2026 Community Mental Health 
Center (CMHC) Partial Hospitalization Program (PHP), and Intensive 
Outpatient Program (IOP) costs based on 40 percent of the corresponding 
proposed hospital-based PHP and IOP costs. This change would resolve a 
cost inversion in CMHC cost data that resulted in higher geometric mean 
costs for 3-service days than for 4-service days. It would also 
stabilize rates for CMHCs by basing them on data from a much larger set 
of providers while preserving the adjustment for the structural 
differences between CMHC and hospital costs.
    <bullet<ls-thn-eq> Notice of Intent to Conduct a Medicare OPPS 
Drugs Acquisition Cost

[[Page 33481]]

Survey: Section 1833(t)(14)(D)(ii) of the Act requires the Secretary to 
periodically conduct surveys of hospital acquisition costs for each 
specified covered outpatient drug for use in setting the payment rates 
for such drugs. Additionally, on April 18, 2025, President Trump signed 
Executive Order (E.O.) 14273, ``Lowering Drug Prices by Once Again 
Putting Americans First.'' Section 5 of the E.O., ``Appropriately 
Accounting for Acquisition Costs of Drugs in Medicare,'' which directs 
the Secretary of HHS to publish in the Federal Register a plan to 
conduct a survey under section 1833(t)(14)(D)(ii) of the Act so he can 
determine the hospital acquisition cost for covered outpatient drugs at 
hospital outpatient departments. Accordingly, we will be conducting a 
survey, with the survey submission window opening by early CY 2026, of 
the acquisition costs for each separately payable drug acquired by all 
hospitals paid under the OPPS. We intend for the survey to be completed 
in time for the survey results to be used to inform policymaking 
beginning with the CY 2027 OPPS/ASC proposed rule.
    <bullet> Two-Midnight Rule Medical Review Activities Exemptions: 
For CY 2026, we propose to continue our existing policy exempting 
procedures that are removed from the inpatient only (IPO) list under 
the OPPS from certain medical review activities related to the two-
midnight policy. Under this policy, procedures removed from the IPO 
list are exempted from site-of-service claim denials, Beneficiary and 
Family-Centered Care Quality Improvement Organization (BFCC-QIO) 
referrals to Recovery Audit Contractor (RAC) for persistent 
noncompliance with the 2-midnight rule, and RAC reviews for ``patient 
status'' (that is, site-of-service) until claims data demonstrates that 
the procedures are more commonly billed in the outpatient setting than 
the inpatient setting. We also propose to revise 42 CFR 412.3(d)(2) for 
clarity.
    <bullet<ls-thn-eq> Virtual Direct Supervision of Pulmonary 
Rehabilitation (PR), Coronary Rehabilitation (CR), Intensive Coronary 
Rehabilitation and Diagnostic Services. For CY 2026, we propose to 
revise Sec.  410.27(a)(1)(iv)(B)(1) and Sec.  410.28(e)(2)(iii) to make 
the availability of the direct supervision of CR, ICR, PR services and 
diagnostic services via audio-video real-time communications technology 
(excluding audio-only) permanent, except for diagnostic services that 
have a global period indicator of 010 or 090.
    <bullet<ls-thn-eq> Prospective Adjustment to Payments for Non-Drug 
Items and Services to Offset the Increased Payments for Non-Drug Items 
and Services Made in CY 2018 Through CY 2022 as a Result of the 340B 
Payment Policy. For CY 2026, we propose to revise the reduction to the 
OPPS conversion factor under Sec.  419.32(b)(1)(iv)(B)(12) used to 
determine the payment amounts for non-drug items and services for 
hospitals for whom this adjustment applies from 0.5 percent to 2 
percent. The Remedy for the 340B-Acquired Drug Payment Policy for 
Calendar Years 2018-2022 (88 FR 77150) codified a 0.5 percent reduction 
in the OPPS conversion factor applicable to non-drug items and 
services, excluding hospitals that enrolled in Medicare after January 
1, 2018. This 0.5 percent reduction would remain in effect until the 
estimated payment reduction reached the estimated $7.8 billion of 
increased non-drug item and services payments made from CY 2018 through 
CY 2022, which we estimated would occur in CY 2041. This prospective 
offset aimed to balance the goal of restoring hospitals to their 
financial position had the original 340B policy never existed, while 
avoiding burdening them with an immediate single year recovery. After 
subsequent reconsideration of balancing these two goals, we have 
determined a shorter timeframe to be more appropriate. This proposed 2 
percent reduction would remain in effect for certain hospitals until 
the estimated payment reduction reaches $7.8 billion, which we estimate 
will occur in CY 2031.
    <bullet<ls-thn-eq> Payment for Skin Substitute Products under the 
OPPS. For CY 2026, we propose to separately pay for the provision of 
certain groups of skin substitute products as supplies when they are 
used during a covered application procedure paid under the PFS in the 
non-facility setting or under the OPPS. We propose to group skin 
substitutes that are not drugs or biologicals using three FDA 
regulatory categories (PMAs, 510(k)s, and 361 HCT/Ps) to set payment 
rates. To effectuate this categorization into a payment policy under 
the OPPS, we propose to create three new APCs for HCPCS codes that 
describe skin substitute products organized by clinical and resource 
similarity. These three APCs will divide skin substitutes by their FDA 
regulatory pathway. Specifically, we propose to create: APC 6000 (PMA 
Skin Substitute Products); APC 6001 (510(k) Skin Substitute Products); 
and APC 6002 (361 HCT/P Skin Substitute Products). This proposal would 
result in an initial payment rate of $125.38 for each of the new 
proposed APCs. We propose implementing this policy in both the non-
facility, ambulatory surgical center setting, and outpatient hospital 
settings.
    <bullet<ls-thn-eq> Method to Control Unnecessary Increases in the 
Volume of Outpatient Services Furnished in Excepted Off-Campus 
Provider-Based Departments (PBDs): For CY 2026, we propose to use our 
authority under section 1833(t)(2)(F) of the Act to apply the Physician 
Fee Schedule equivalent rate for any HPCPCs codes assigned to the drug 
administration services APCs, when provided at an off-campus PBD 
excepted from section 1833(t)(21) of the Act. We propose to exempt 
rural Sole Community Hospitals from this method to control the 
unnecessary volume of drug administration services. Finally, we are 
requesting information on expanding our volume control method to on-
campus clinic visits.
    <bullet<ls-thn-eq> Request for information on Adjusting Payment 
under the OPPS for Services Predominately Performed in the Ambulatory 
Surgical Center or Physician Office Settings: For CY 2026, we are 
requesting information for future rulemaking on the development of a 
systematic process for identifying ambulatory services at high risk of 
shifting to the hospital setting based on financial incentives rather 
than medical necessity and adjusting payments according.
    <bullet<ls-thn-eq> Request for information on Software as a 
Service: We are issuing a request for information on alternative and 
consistent payment methods for software as a service (SaaS) services 
under the OPPS to consider for future rulemaking. We intend to identify 
whether specific adjustments to our payment policies for SaaS services 
are needed to more accurately and appropriately pay for these products 
and services across settings of care.
    <bullet<ls-thn-eq> Proposed Market-Based MS-DRG Relative Weight 
Data Collection and Change in Methodology for Calculating MS-DRG 
Relative Weights Under the Inpatient Prospective Payment System: As 
discussed in section XX. of the proposed rule, in order to reduce the 
Medicare program's reliance on the hospital chargemaster, and to 
support the development of a market-based approach to payment under the 
Medicare FFS system, we propose that hospitals would be required to 
report certain market-based payment rate information on their Medicare 
cost report for cost reporting periods ending on or after January 1, 
2026, to be used in a proposed change to the methodology for 
calculating the IPPS MS-DRG relative weights to reflect

[[Page 33482]]

relative market-based pricing. Specifically, the market-based rate 
information we propose to collect on the Medicare cost report would be 
the median of the payer-specific negotiated charges by MS-DRG, for a 
hospital's MA organizations (MAOs). As described further in section 
XX.C.2. of this proposed rule, we specifically propose that for the 
purposes of reporting the data on the cost report, hospitals would 
report the median of the payer-specific negotiated charges for an MS-
DRG that the hospital has disclosed for all of its MAOs on the most 
recent version of the machine-readable file (MRF) that the hospital is 
required to disclose under the hospital price transparency regulations 
at 45 CFR part 180. We also propose a change to the methodology for 
calculating the IPPS MS-DRG relative weights to incorporate this 
market-based rate information, beginning in FY 2029. This proposed MS-
DRG relative weight methodology would utilize the proposed median 
payer-specific negotiated charge information, collected on the cost 
report, for calculating the MS-DRG relative weights.
    <bullet<ls-thn-eq> Graduate Medical Education (GME) Accreditation: 
In order to ensure that accreditation for approved medical residency 
programs is in compliance with applicable laws related to race-based 
admission policies and to improve the accreditation process, we propose 
that accreditors may not require as part of accreditation, or otherwise 
encourage institutions to put in place, diversity, equity, and 
inclusion programs that encourage unlawful discrimination on the basis 
of race or other violations of Federal law. We also note that the 
Secretary may recognize other organizations that meet or exceed 
Medicare's requirements as accreditors in order to increase the 
potential for competition in the accreditation space and improve the 
quality of the accreditation process. The effective date of this 
proposal would be January 1, 2026.
    <bullet<ls-thn-eq> Proposed Updates to Requirements for Hospitals 
to Make Public a List of Their Standard Charges: We propose amendments 
to the hospital price transparency (HPT) regulations to enhance clarity 
and standardization in hospital pricing disclosures. Specifically, we 
propose revisions to Sec.  180.20 to add definitions for ``tenth (10th) 
percentile allowed amount,'' ``median allowed amount,'' and ``ninetieth 
(90th) percentile allowed amount,'' to more accurately reflect the 
distribution of actual amounts that the hospital has received for an 
item or service. In tandem with this, we propose revisions to Sec.  
180.50 to remove the requirement for hospitals to encode the estimated 
allowed amount and instead require hospitals, beginning January 1, 
2026, to disclose the 10th percentile, median, and 90th percentile 
allowed amounts in machine-readable files (MRFs) when standard charges 
are based on percentages or algorithms, as well as the count of allowed 
amounts. We also propose that hospitals should use EDI 835 transaction 
remittance advice (ERA) transaction data to calculate and encode these 
values, and we propose specific instructions to hospitals with regard 
to the methodology, including lookback period, that should be used to 
calculate these amounts. We propose revisions to Sec.  180.50(a)(3) to 
update the attestation language hospitals must include in the MRF and 
to require hospitals to encode the name of the chief executive officer, 
president or senior hospital official designated to oversee the 
encoding of true, accurate, and complete data in the MRF. We also 
propose revisions to Sec.  180.50(b)(2)(i)(A) to require hospitals, 
beginning January 1, 2026, to encode in a newly created general data 
element in the MRF their Type 2 (organizational) National Provider 
Identifier(s) (NPI). Finally, to encourage faster resolution and 
payment of CMPs and in exchange for a hospital's admission of having 
violated HPT requirements, we propose to update Sec.  180.90 to allow 
hospitals, under certain circumstances, the opportunity to have the 
amount of a CMP reduced by 35 percent where the hospital waives its 
right to an ALJ hearing. These proposed changes aim to improve price 
transparency, facilitate efficient enforcement, and empower consumers 
with actionable pricing information.
3. Summary of Costs and Benefits
    In section XXV. of this proposed rule, we set forth a detailed 
analysis of the regulatory and Federalism impacts that the proposed 
changes would have on affected entities and beneficiaries. Key 
estimated impacts are described below.
a. Impacts of all OPPS Changes
    Table 112 in section XXV.C. of this proposed rule displays the 
distributional impact of all the OPPS changes on various groups of 
hospitals and CMHCs for CY 2026 compared to all estimated OPPS payments 
in CY 2025. We estimate that the proposed policies in this proposed 
rule would result in a 1.9 percent increase in OPPS payments to 
providers for services prior to the 340B remedy offset. We estimate 
that total OPPS payments for CY 2026, including beneficiary cost-
sharing, to the approximately 4,000 facilities paid under the OPPS 
(including general acute care hospitals, children's hospitals, cancer 
hospitals, and CMHCs) would increase by approximately $1.61 billion 
compared to CY 2025 payments due to the OPD update, excluding changes 
in enrollment, utilization, and case-mix. However, for providers 
subject to the 340B remedy offset, the 340B remedy offset is estimated 
to reduce payments by $1.1 billion in CY 2026.
    We estimated the isolated impact of our OPPS policies on CMHCs 
because CMHCs have historically only been paid for partial 
hospitalization services under the OPPS. Beginning CY 2024, they are 
also paid for IOP services under the OPPS. Based on our proposal to 
calculate CMHC PHP and IOP costs based on 40 percent of the 
corresponding proposed hospital-based PHP and IOP costs, we estimate a 
0.6 percent increase in CY 2026 payments to CMHCs relative to their CY 
2025 payments.
b. Impacts of the Updated Wage Indexes
    We estimate that our update of the wage indexes based on the fiscal 
year (FY) 2026 IPPS proposed rule wage indexes will result in a 0.1 
percent increase for urban hospitals under the OPPS and a 0.4 percent 
increase for rural hospitals. These wage indexes include continued 
implementation of the Office of Management and Budget (OMB) labor 
market area delineations based on 2020 Decennial Census data, with 
updates, as discussed in section II.C. of this proposed rule.
c. Impacts of the Rural Adjustment and the Cancer Hospital Payment 
Adjustment
    For CY 2026, we proposed to continue to provide additional payments 
to cancer hospitals so that a cancer hospital's payment-to-cost ratio 
(PCR) after the additional payments is equal to the weighted average 
PCR for the other OPPS hospitals using the most recently submitted or 
settled cost report data. Section 16002(b) of the 21st Century Cures 
Act requires that this weighted average PCR be reduced by 1.0 
percentage point. In light of the COVID-19 PHE impact on claims and 
cost data used to calculate the target PCR, we maintained the CY 2021 
target PCR of 0.89 through CYs 2022 and 2023. However, in CY 2024, we 
finalized a policy to reduce the target PCR by 1.0 percentage point 
each calendar year until the target PCR equals the PCR of non-cancer 
hospitals using the most recently submitted or settled cost report 
data. For CY 2025, we finalized a target PCR of 0.87. For CY 2026, we 
propose

[[Page 33483]]

a target PCR of 0.87, the same PCR of non-cancer hospitals using the 
most recently submitted or settled cost report data, to determine the 
CY 2026 cancer hospital payment adjustment to be paid at cost report 
settlement. That is, the payment adjustments would be the additional 
payments needed to result in a PCR equal to 0.87 for each cancer 
hospital.
d. Impacts of the OPD Fee Schedule Increase Factor
    For the CY 2026 OPPS/ASC, we are establishing an OPD fee schedule 
increase factor of 2.4 percent and applying that increase factor to the 
conversion factor for CY 2025. As a result of the OPD fee schedule 
increase factor and other budget neutrality adjustments, we estimate 
that urban hospitals would experience an increase in payments of 
approximately 2.6 percent and that rural hospitals would experience an 
increase in payments of 2.5 percent. Classifying hospitals by teaching 
status, we estimate non-teaching hospitals would experience an increase 
in payments of 2.6 percent, minor teaching hospitals would experience 
an increase in payments of 2.8 percent, and major teaching hospitals 
would experience an increase in payments of 2.3 percent. We also 
classified hospitals by the type of ownership. We estimate that 
hospitals with voluntary ownership would experience an increase of 2.5 
percent in payments, while hospitals with government ownership would 
experience an increase of 2.5 percent in payments. We estimate that 
hospitals with proprietary ownership will experience an increase of 3.0 
percent in payments.
e. Impacts of the ASC Payment Update
    For impact purposes, the surgical procedures on the ASC covered 
surgical procedure list are aggregated into surgical specialty groups 
using CPT and HCPCS code range definitions. The percentage change in 
estimated total payments by specialty groups under the proposed CY 2026 
payment rates, compared to estimated CY 2025 payment rates, generally 
ranges between an increase of 1 percent and an increase of 3 percent, 
depending on the service, with some exceptions from expected 
utilization changes with new CY 2026 AMA CPT codes.
f. Impacts of the Proposed Market-Based MS-DRG Relative Weight Data 
Collection and Change in Methodology for Calculating MS-DRG Relative 
Weights Under the Inpatient Prospective Payment System.
    In section XX. of this proposed rule, we seek comment on a proposed 
methodology for estimating the MS-DRG relative weights beginning in FY 
2029 based on the median payer-specific negotiated charge information 
we propose to collect on the cost report. We note that the estimated 
total annual burden hours for this proposal are as follows: 3,038 
hospitals times 20 hours per hospital equals 60,760 annual burden hours 
and $4,857,458.20. We refer readers to section XXII.E. of this proposed 
rule for further analysis of this assessment.
g. Impacts of Hospital Price Transparency
    We propose to require hospitals to report four new data elements 
when the payer-specific negotiated charge is based on a percentage or 
algorithm--the median allowed amount (which would replace the estimated 
allowed amount data element), the 10th percentile allowed amount, the 
90th percentile allowed amount, and the count of allowed amounts. We 
also propose to update the attestation language hospitals must include 
in the MRF and to require hospitals to encode the name of the chief 
executive officer, president or senior official designated to oversee 
the encoding of true, accurate and complete data in the MRF. 
Additionally, we propose to require hospitals to add their National 
Provider Identifiers (NPIs) to the MRF. The proposals would advance the 
comparability of standard charge information across hospitals and of 
the HPT data with other healthcare data, including health plan 
transparency data from the Transparency in Coverage (TiC) MRFs. These 
proposals include a one-time burden of $478.08 per hospital, and a 
total national cost of $3,545,441.28 ($478.08 x 7,416 hospitals). As 
discussed in detail in section XIX. of this proposed rule, we believe 
that the benefits to the public (and to hospitals themselves) outweigh 
the burden imposed on hospitals.

B. Legislative and Regulatory Authority for the Hospital OPPS

    When Title XVIII of the Act was enacted, Medicare payment for 
hospital outpatient services was based on hospital-specific costs. In 
an effort to ensure that Medicare and its beneficiaries pay 
appropriately for services and to encourage more efficient delivery of 
care, the Congress mandated replacement of the reasonable cost-based 
payment methodology with a prospective payment system (PPS). The 
Balanced Budget Act of 1997 (BBA) (Pub. L. 105-33) added section 
1833(t) to the Act, authorizing implementation of a PPS for hospital 
outpatient services. The OPPS was first implemented for services 
furnished on or after August 1, 2000. Implementing regulations for the 
OPPS are located at 42 CFR parts 410 and 419.
    The Medicare, Medicaid, and SCHIP Balanced Budget Refinement Act of 
1999 (BBRA) (Pub. L. 106-113) made major changes in the hospital OPPS. 
The following Acts made additional changes to the OPPS: the Medicare, 
Medicaid, and SCHIP Benefits Improvement and Protection Act of 2000 
(BIPA) (Pub. L. 106-554); the Medicare Prescription Drug, Improvement, 
and Modernization Act of 2003 (MMA) (Pub. L. 108-173); the Deficit 
Reduction Act of 2005 (DRA) (Pub. L. 109-171), enacted on February 8, 
2006; the Medicare Improvements and Extension Act under Division B of 
Title I of the Tax Relief and Health Care Act of 2006 (MIEA-TRHCA) 
(Pub. L. 109-432), enacted on December 20, 2006; the Medicare, 
Medicaid, and SCHIP Extension Act of 2007 (MMSEA) (Pub. L. 110-173), 
enacted on December 29, 2007; the Medicare Improvements for Patients 
and Providers Act of 2008 (MIPPA) (Pub. L. 110-275), enacted on July 
15, 2008; the Patient Protection and Affordable Care Act (Pub. L. 111-
148), enacted on March 23, 2010, as amended by the Health Care and 
Education Reconciliation Act of 2010 (HCERA, Pub. L. 111-152), enacted 
on March 30, 2010 (these two public laws are collectively known as the 
Affordable Care Act); the Medicare and Medicaid Extenders Act of 2010 
(MMEA, Pub. L. 111-309); the Temporary Payroll Tax Cut Continuation Act 
of 2011 (TPTCCA, Pub. L. 112-78), enacted on December 23, 2011; the 
Middle Class Tax Relief and Job Creation Act of 2012 (MCTRJCA, Pub. L. 
112-96), enacted on February 22, 2012; the American Taxpayer Relief Act 
of 2012 (Pub. L. 112-240), enacted January 2, 2013; the Pathway for SGR 
Reform Act of 2013 (Pub. L. 113-67) enacted on December 26, 2013; the 
Protecting Access to Medicare Act of 2014 (PAMA, Pub. L. 113-93), 
enacted on March 27, 2014; the Medicare Access and CHIP Reauthorization 
Act (MACRA) of 2015 (Pub. L. 114-10), enacted April 16, 2015; the 
Bipartisan Budget Act of 2015 (Pub. L. 114-74), enacted November 2, 
2015; the Consolidated Appropriations

[[Page 33484]]

Act, 2016 (Pub. L. 114-113), enacted on December 18, 2015, the 21st 
Century Cures Act (Pub. L. 114-255), enacted on December 13, 2016; the 
Consolidated Appropriations Act, 2018 (Pub. L. 115-141), enacted on 
March 23, 2018; the Substance Use Disorder- Prevention that Promotes 
Opioid Recovery and Treatment for Patients and Communities Act (Pub. L. 
115-271), enacted on October 24, 2018; the Further Consolidated 
Appropriations Act, 2020 (Pub. L. 116-94), enacted on December 20, 
2019; the Coronavirus Aid, Relief, and Economic Security Act (Pub. L. 
116-136), enacted on March 27, 2020; the Consolidated Appropriations 
Act, 2021 (Pub. L. 116-260), enacted on December 27, 2020; the 
Inflation Reduction Act, 2022 (Pub. L. 117-169), enacted on August 16, 
2022; and the Consolidated Appropriations Act (CAA), 2023 (Pub. L. 117-
238), enacted December 29, 2022.
    Under the OPPS, we generally pay for hospital Part B services on a 
rate-per-service basis that varies according to the APC group to which 
the service is assigned. We use the Healthcare Common Procedure Coding 
System (HCPCS) (which includes certain Current Procedural Terminology 
(CPT) codes) to identify and group the services within each APC. The 
OPPS includes payment for most hospital outpatient services, except 
those identified in section I.C of this proposed rule. Section 
1833(t)(1)(B) of the Act provides for payment under the OPPS for 
hospital outpatient services designated by the Secretary (which 
includes partial hospitalization services furnished by CMHCs), and 
certain inpatient hospital services that are paid under Medicare Part 
B.
    The OPPS rate is an unadjusted national payment amount that 
includes the Medicare payment and the beneficiary copayment. This rate 
is divided into a labor-related amount and a nonlabor-related amount. 
The labor-related amount is adjusted for area wage differences using 
the hospital inpatient wage index value for the locality in which the 
hospital or CMHC is located.
    All services and items within an APC group are comparable 
clinically and with respect to resource use, as required by section 
1833(t)(2)(B) of the Act. In accordance with section 1833(t)(2)(B) of 
the Act, subject to certain exceptions, items and services within an 
APC group cannot be considered comparable with respect to the use of 
resources if the highest median cost (or mean cost, if elected by the 
Secretary) for an item or service in the APC group is more than 2 times 
greater than the lowest median cost (or mean cost, if elected by the 
Secretary) for an item or service within the same APC group (referred 
to as the ``2 times rule''). In implementing this provision, we 
generally use the cost of the item or service assigned to an APC group.
    For new technology items and services, special payments under the 
OPPS may be made in one of two ways. section 1833(t)(6) of the Act 
provides for temporary additional payments, which we refer to as 
``transitional pass-through payments,'' for at least 2 but not more 
than 3 years for certain drugs, biological agents, brachytherapy 
devices used for the treatment of cancer, and categories of other 
medical devices. For new technology services that are not eligible for 
transitional pass-through payments, and for which we lack sufficient 
clinical information and cost data to appropriately assign them to a 
clinical APC group, we have established special APC groups based on 
costs, which we refer to as New Technology APCs. These New Technology 
APCs are designated by cost bands which allow us to provide appropriate 
and consistent payment for designated new procedures that are not yet 
reflected in our claims data. Similar to pass-through payments, an 
assignment to a New Technology APC is temporary; that is, we retain a 
service within a New Technology APC until we acquire sufficient data to 
assign it to a clinically appropriate APC group.

C. Excluded OPPS Services and Hospitals

    Section 1833(t)(1)(B)(i) of the Act authorizes the Secretary to 
designate the hospital outpatient services that are paid under the 
OPPS. While most hospital outpatient services are payable under the 
OPPS, section 1833(t)(1)(B)(iv) of the Act excludes payment for 
ambulance, physical and occupational therapy, and speech-language 
pathology services, for which payment is made under a fee schedule. It 
also excludes screening mammography, diagnostic mammography, and 
effective January 1, 2011, an annual wellness visit providing 
personalized prevention plan services. The Secretary exercises the 
authority granted under the statute to also exclude from the OPPS 
certain services that are paid under fee schedules or other payment 
systems. Such excluded services include, for example, the professional 
services of physicians and nonphysician practitioners paid under the 
Medicare Physician Fee Schedule (MPFS); certain laboratory services 
paid under the Clinical Laboratory Fee Schedule (CLFS); services for 
beneficiaries with end-stage renal disease (ESRD) that are paid under 
the ESRD prospective payment system; and services and procedures that 
require an inpatient stay that are paid under the hospital IPPS. In 
addition, section 1833(t)(1)(B)(v) of the Act does not include 
applicable items and services (as defined in subparagraph (A) of 
paragraph (21)) that are furnished on or after January 1, 2017, by an 
off-campus outpatient department of a provider (as defined in 
subparagraph (B) of paragraph (21)). We set forth the services that are 
excluded from payment under the OPPS in regulations at 42 CFR 419.22.
    Under Sec.  419.20(b) of the regulations, we specify the types of 
hospitals that are excluded from payment under the OPPS. These excluded 
hospitals are:
    <bullet> Critical access hospitals (CAHs);
    <bullet> Hospitals located in Maryland and paid under Maryland's 
All-Payer or Total Cost of Care Model;
    <bullet> Hospitals located outside of the 50 States, the District 
of Columbia, and Puerto Rico;
    <bullet> Indian Health Service (IHS) hospitals; and
    <bullet> Rural emergency hospitals (REH).

D. Prior Rulemaking

    On April 7, 2000, we published in the Federal Register a final rule 
with comment period (65 FR 18434) to implement a prospective payment 
system for hospital outpatient services. The hospital OPPS was first 
implemented for services furnished on or after August 1, 2000. Section 
1833(t)(9)(A) of the Act requires the Secretary to review certain 
components of the OPPS, not less often than annually, and to revise the 
groups, the relative payment weights, and the wage and other 
adjustments to take into account changes in medical practices, changes 
in technology, the addition of new services, new cost data, and other 
relevant information and factors.
    Since initially implementing the OPPS, we have published final 
rules in the Federal Register annually to implement statutory 
requirements and changes arising from our continuing experience with 
this system. These rules can be viewed on the CMS website at: <a href="https://www.cms.gov/medicare/payment/prospective-payment-systems/hospital-outpatient/regulations-notices">https://www.cms.gov/medicare/payment/prospective-payment-systems/hospital-outpatient/regulations-notices</a>.

E. Advisory Panel on Hospital Outpatient Payment (the HOP Panel or the 
Panel)

1. Authority of the Panel
    Section 1833(t)(9)(A) of the Act, as amended by section 201(h) of 
Public Law 106-113, and redesignated by section 202(a)(2) of Public Law 
106-113,

[[Page 33485]]

requires that we consult with an expert outside advisory panel composed 
of an appropriate selection of representatives of providers to annually 
review (and advise the Secretary concerning) the clinical integrity of 
the payment groups and their weights under the OPPS. In CY 2000, based 
on section 1833(t)(9)(A) of the Act, the Secretary established the 
Advisory Panel on Ambulatory Payment Classification Groups (APC Panel) 
to fulfill this requirement. In CY 2011, based on section 222 of the 
Public Health Service Act (the PHS Act), which gives discretionary 
authority to the Secretary to convene advisory councils and committees, 
the Secretary expanded the panel's scope to include the supervision of 
hospital outpatient therapeutic services in addition to the APC groups 
and weights. To reflect this new role of the panel, the Secretary 
changed the panel's name to the Advisory Panel on Hospital Outpatient 
Payment (the HOP Panel). The HOP Panel is not restricted to using data 
compiled by CMS, and in conducting its review, it may use data 
collected or developed by organizations outside the Department.
2. Establishment of the Panel
    On November 21, 2000, the Secretary signed the initial charter 
establishing the Panel, and, at that time, named the APC Panel. This 
expert panel is composed of appropriate representatives of providers 
(currently employed full-time, not as consultants, in their respective 
areas of expertise) who review clinical data and advise CMS about the 
clinical integrity of the APC groups and their payment weights. Since 
CY 2012, the Panel also is charged with advising the Secretary on the 
appropriate level of supervision for individual hospital outpatient 
therapeutic services. The Panel is technical in nature, and it is 
governed by the provisions of the Federal Advisory Committee Act 
(FACA). The current charter specifies, among other requirements, that 
the Panel--
    <bullet> May advise on the clinical integrity of Ambulatory Payment 
Classification (APC) groups and their associated weights;
    <bullet> May advise on the appropriate supervision level for 
hospital outpatient services;
    <bullet> May advise on OPPS APC rates for ASC covered surgical 
procedures;
    <bullet> Continues to be technical in nature;
    <bullet> Is governed by the provisions of the FACA;
    <bullet> Has a Designated Federal Official (DFO); and
    <bullet> Is chaired by a Federal Official designated by the 
Secretary.
    The Panel's charter was amended on November 15, 2011, renaming the 
Panel and expanding the Panel's authority to include supervision of 
hospital outpatient therapeutic services and to add critical access 
hospital (CAH) representation to its membership. The Panel's charter 
was also amended on November 6, 2014 (80 FR 23009), and the number of 
members was revised from up to 19 to up to 15 members. The Panel's 
current charter was approved on November 21, 2024, for a 2-year period.
    The current Panel membership and other information pertaining to 
the Panel, including its charter, Federal Register notices, membership, 
meeting dates, agenda topics, and meeting reports, can be viewed on the 
CMS website at <a href="https://www.cms.gov/Regulations-and-Guidance/Guidance/FACA/AdvisoryPanelonAmbulatoryPaymentClassificationGroups.html">https://www.cms.gov/Regulations-and-Guidance/Guidance/FACA/AdvisoryPanelonAmbulatoryPaymentClassificationGroups.html</a>.
3. Panel Meetings and Organizational Structure
    The Panel has held many meetings, with the last meeting taking 
place on August 26, 2024. The recommendations of the Panel for the most 
recent meeting are available on the CMS website at <a href="https://www.cms.gov/medicare/regulations-guidance/advisory-committees/hospital-outpatient-payment">https://www.cms.gov/medicare/regulations-guidance/advisory-committees/hospital-outpatient-payment</a>. Prior to each meeting, we publish a notice in the Federal 
Register to announce the meeting, new members, and any other changes of 
which the public should be aware. Beginning in CY 2017, we have 
transitioned to one meeting per year (81 FR 31941). In CY 2022, we 
published a Federal Register notice requesting nominations to fill 
vacancies on the Panel (87 FR 68499). We are currently accepting 
nominations at: <a href="https://mearis.cms.gov">https://mearis.cms.gov</a>.
    In addition, the Panel has established an administrative structure 
that, in part, currently includes the use of three subcommittee 
workgroups to provide preparatory meeting and subject support to the 
larger panel. The three current subcommittees include the following:
    <bullet> APC Groups and Status Indicator Assignments Subcommittee, 
which advises and provides recommendations to the Panel on the 
appropriate status indicators to be assigned to HCPCS codes, including 
but not limited to whether a HCPCS code or a category of codes should 
be packaged or separately paid, as well as the appropriate APC 
assignment of HCPCS codes regarding services for which separate payment 
is made.
    <bullet> Data Subcommittee, which is responsible for studying the 
data issues confronting the Panel and for recommending options for 
resolving them; and
    <bullet> Visits and Observation Subcommittee, which reviews and 
makes recommendations to the Panel on all technical issues pertaining 
to observation services and hospital outpatient visits paid under the 
OPPS.
    Each of these workgroup subcommittees was established by a majority 
vote from the full Panel during a scheduled Panel meeting, and the 
Panel recommended at the August 26, 2024, meeting that the 
subcommittees continue. We accepted this recommendation.
    For discussions of earlier Panel meetings and recommendations, we 
refer readers to previously published OPPS/ASC proposed and final 
rules, the CMS website mentioned earlier in this section, and the FACA 
database at <a href="https://facadatabase.gov">https://facadatabase.gov</a>.

F. Public Comments Received on the CY 2025 OPPS/ASC Final Rule With 
Comment Period

    We received approximately 29 timely pieces of correspondence on the 
CY 2025 OPPS/ASC final rule with comment period that appeared in the 
Federal Register on November 27, 2024 (88 FR 93912).

II. Updates Affecting OPPS Payments

A. Recalibration of APC Relative Payment Weights

1. Database Construction
a. Database Source and Methodology
    Section 1833(t)(9)(A) of the Act requires that the Secretary review 
not less often than annually and revise the relative payment weights 
for Ambulatory Payment Classifications (APCs). In the April 7, 2000, 
OPPS final rule with comment period (65 FR 18482), we explained in 
detail how we calculated the relative payment weights that were 
implemented on August 1, 2000, for each APC group.
    For the CY 2026 OPPS, we propose to recalibrate the APC relative 
payment weights for services furnished on or after January 1, 2026, and 
before January 1, 2027 (CY 2026), using the same basic methodology that 
we described in the CY 2025 OPPS/ASC final rule with comment period (89 
FR 93921 through 93922), using CY 2024 claims data. That is, we propose 
to recalibrate the relative payment weights for each APC based on 
claims and cost report data for hospital outpatient department (HOPD) 
services to construct a database for calculating APC group weights.
    For the purpose of recalibrating the proposed APC relative payment 
weights

[[Page 33486]]

for CY 2026, we began with approximately 143 million final action 
claims (claims for which all disputes and adjustments have been 
resolved and payment has been made) for HOPD services furnished on or 
after January 1, 2024, and before January 1, 2025, before applying our 
exclusionary criteria and other methodological adjustments. After the 
application of those data processing changes, we used approximately 76 
million final action claims to develop the proposed CY 2026 OPPS 
payment weights. For exact numbers of claims used and additional 
details on the claims accounting process, we refer readers to the 
claims accounting narrative under supporting documentation for this 
proposed rule on the CMS website at <a href="https://www.cms.gov/medicare/payment/prospective-payment-systems/hospital-outpatient">https://www.cms.gov/medicare/payment/prospective-payment-systems/hospital-outpatient</a>.
    Addendum N to this proposed rule (which is available via the 
internet on the CMS website at <a href="https://www.cms.gov/medicare/payment/prospective-payment-systems/hospital-outpatient/regulations-notices">https://www.cms.gov/medicare/payment/prospective-payment-systems/hospital-outpatient/regulations-notices</a>) 
includes the proposed list of bypass codes for CY 2026. The proposed 
list of bypass codes contains codes that are reported on claims for 
services in CY 2024 and, therefore, includes codes that were in effect 
in CY 2024 and used for billing. We propose to retain these deleted 
bypass codes on the proposed CY 2026 bypass list because these codes 
existed in CY 2024 and were covered HOPD services in that period, and 
CY 2024 claims data were used to calculate proposed CY 2026 payment 
rates. Keeping these deleted bypass codes on the bypass list 
potentially allows us to create more ``pseudo'' single procedure claims 
for ratesetting purposes. ``Overlap bypass codes'' that are members of 
the proposed multiple imaging composite APCs are identified by 
asterisks (*) in the third column of Addendum N to this proposed rule. 
HCPCS codes that we propose to add for CY 2026 are identified by 
asterisks (*) in the fourth column of Addendum N.
b. Proposed Calculation and Use of Cost-to-Charge Ratios (CCRs)
    For CY 2026, we propose to continue to use the hospital-specific 
overall ancillary and departmental cost-to-charge ratios (CCRs) to 
convert charges to estimated costs through application of a revenue 
code-to-cost center crosswalk. To calculate the APC costs on which the 
proposed CY 2026 APC payment rates are based, we calculated hospital-
specific departmental CCRs for each hospital for which we had CY 2024 
claims data by comparing these claims data to the most recently 
available hospital cost reports, which, in most cases, are from CY 
2023. For the proposed CY 2026 OPPS payment rates, we used the set of 
claims processed during CY 2024. We applied the hospital-specific CCR 
to the hospital's charges at the most detailed level possible, based on 
a revenue code-to-cost center crosswalk that contains a hierarchy of 
CCRs used to estimate costs from charges for each revenue code. To 
ensure the completeness of the revenue code-to-cost center crosswalk, 
we reviewed changes to the list of revenue codes for CY 2024 (the year 
of claims data we used to calculate the proposed CY 2026 OPPS payment 
rates) and updates to the National Uniform Billing Committee (NUBC) 
2024 Data specifications Manual. That crosswalk is available for review 
and continuous comment on the CMS website at <a href="https://www.cms.gov/medicare/payment/prospective-payment-systems/hospital-outpatient">https://www.cms.gov/medicare/payment/prospective-payment-systems/hospital-outpatient</a>.
    In accordance with our longstanding policy, similar to our 
finalized policy for CY 2025 OPPS ratesetting, we propose to calculate 
CCRs for the standard cost centers--cost centers with a predefined 
label--and nonstandard cost centers--cost centers defined by a 
hospital--accepted by the electronic cost report database. In general, 
the most detailed level at which we calculate CCRs is the hospital-
specific departmental level.
    While we generally view the use of additional cost data as 
improving our OPPS ratesetting process, we have historically not 
included cost report lines for certain nonstandard cost centers in the 
OPPS ratesetting database construction when hospitals have reported 
these nonstandard cost centers on cost report lines that do not 
correspond to the cost center number. We believe it is important to 
further investigate the accuracy of these cost report data before 
including such data in the ratesetting process. Further, we believe it 
is appropriate to gather additional information from the public as well 
before including the data in OPPS ratesetting. For CY 2026, we propose 
not to include the nonstandard cost centers reported in this way in the 
OPPS ratesetting database construction.
2. Proposed Data Development and Calculation of Costs Used for 
Ratesetting
    In this section of this proposed rule, we discuss the use of claims 
to calculate the OPPS payment rates for CY 2026. The Hospital OPPS page 
on the CMS website on which this proposed rule is posted (<a href="https://www.cms.gov/medicare/payment/prospective-payment-systems/hospital-outpatient">https://www.cms.gov/medicare/payment/prospective-payment-systems/hospital-outpatient</a>) provides an accounting of claims used in the development of 
the proposed payment rates. That accounting provides additional detail 
regarding the number of claims derived at each stage of the process. In 
addition, later in this section we discuss the file of claims that 
comprises the data set that is available upon payment of an 
administrative fee under a CMS data use agreement. The CMS website 
<a href="https://www.cms.gov/medicare/payment/prospective-payment-systems/hospital-outpatient">https://www.cms.gov/medicare/payment/prospective-payment-systems/hospital-outpatient</a>, includes information about obtaining the ``OPPS 
Limited Data Set,'' which now includes the additional variables 
previously available only in the OPPS Identifiable Data Set, including 
International Classification of Diseases, Tenth Revision, Clinical 
Modification (ICD-10-CM) diagnosis codes and revenue code payment 
amounts. This file is derived from the CY 2024 claims that are used to 
calculate the proposed payment rates for this proposed rule.
    Previously, the OPPS established the scaled relative weights on 
which payments are based using APC median costs, a process described in 
the CY 2012 OPPS/ASC final rule with comment period (76 FR 74188). 
However, as discussed in more detail in section II.A.2.f. of the CY 
2013 OPPS/ASC final rule with comment period (77 FR 68259 through 
68271), we finalized the use of geometric mean costs to calculate the 
relative weights on which the CY 2013 OPPS payment rates were based. 
While this policy changed the cost metric on which the relative 
payments are based, the data process in general remained the same under 
the methodologies that we used to obtain appropriate claims data and 
accurate cost information in determining estimated service cost.
    We used the methodology described in sections II.A.2.a. through 
II.A.2.c. of this proposed rule to calculate the costs we used to 
establish the proposed relative payment weights used in calculating the 
OPPS payment rates for CY 2026 shown in Addenda A and B to this 
proposed rule (which are available via the internet on the CMS website 
at <a href="https://www.cms.gov/medicare/payment/prospective-payment-systems/hospital-outpatient/regulations-notices">https://www.cms.gov/medicare/payment/prospective-payment-systems/hospital-outpatient/regulations-notices</a>). We refer readers to section 
II.A.4. of this proposed rule for a discussion of the conversion of APC 
costs to scaled payment weights.
    We note that under the OPPS, CY 2019 was the first year in which 
the claims data used for setting payment rates (CY 2017 data) contained 
lines with the modifier ``PN,'' which indicates nonexcepted items and

[[Page 33487]]

services furnished and billed by off-campus provider-based departments 
(PBDs) of hospitals. Because nonexcepted items and services are not 
paid under the OPPS, in the CY 2019 OPPS/ASC final rule with comment 
period (83 FR 58832), we finalized a policy to remove those claim lines 
reported with modifier ``PN'' from the claims data used in ratesetting 
for the CY 2019 OPPS and subsequent years. For the CY 2026 OPPS, we 
propose to continue to remove claim lines with modifier ``PN'' from the 
ratesetting process.
    For details of the claims accounting process used in this CY 2026 
OPPS/ASC proposed rule, we refer readers to the claims accounting 
narrative under supporting documentation for this proposed rule on the 
CMS website at <a href="https://www.cms.gov/medicare/payment/prospective-payment-systems/hospital-outpatient">https://www.cms.gov/medicare/payment/prospective-payment-systems/hospital-outpatient</a>.
a. Calculation of Single Procedure APC Criteria-Based Costs
(1) Blood and Blood Products
    Since the implementation of the OPPS in August 2000, we have made 
separate payments for blood and blood products through APCs rather than 
packaging payment for them into payments for the procedures with which 
they are administered. Hospital payments for the costs of blood and 
blood products, as well as for the costs of collecting, processing, and 
storing blood and blood products, are made through the OPPS payments 
for specific blood product APCs. We propose to continue to establish 
payment rates for blood and blood products using our blood-specific CCR 
methodology (88 FR 49562), which utilizes actual or simulated CCRs from 
the most recently available hospital cost reports to convert hospital 
charges for blood and blood products to costs. This methodology has 
been our standard ratesetting methodology for blood and blood products 
since CY 2005. It was developed in response to data analysis indicating 
that there was a significant difference in CCRs for those hospitals 
with and without blood-specific cost centers and past public comments 
indicating that the former OPPS policy of defaulting to the overall 
hospital CCR for hospitals not reporting a blood-specific cost center 
often resulted in an underestimation of the true hospital costs for 
blood and blood products. To address the differences in CCRs and to 
better reflect hospitals' costs, our methodology simulates blood CCRs 
for each hospital that does not report a blood cost center by 
calculating the ratio of the blood-specific CCRs to hospitals' overall 
CCRs for those hospitals that do report costs and charges for blood 
cost centers and applies this mean ratio to the overall CCRs of 
hospitals not reporting costs and charges for blood cost centers on 
their cost reports. We propose to calculate the costs upon which the 
proposed payment rates for blood and blood products are based using the 
actual blood-specific CCR for hospitals that reported costs and charges 
for a blood cost center and a hospital-specific, simulated, blood-
specific CCR for hospitals that did not report costs and charges for a 
blood cost center.
    We continue to believe that the hospital-specific, simulated, 
blood-specific CCR methodology takes into account the unique charging 
and cost accounting structure of each hospital, as it better responds 
to the absence of a blood-specific CCR for a hospital than alternative 
methodologies, such as defaulting to the overall hospital CCR or 
applying an average blood-specific CCR across hospitals. This 
methodology also yields more accurate estimated costs for these 
products and results in payment rates for blood and blood products that 
appropriately reflect the relative estimated costs of these products 
for hospitals without blood cost centers and for these blood products 
in general.
    We refer readers to Addendum B to this proposed rule (which is 
available via the internet on the CMS website at <a href="https://www.cms.gov/medicare/payment/prospective-payment-systems/hospital-outpatient/regulations-notices">https://www.cms.gov/medicare/payment/prospective-payment-systems/hospital-outpatient/regulations-notices</a>) for the proposed CY 2026 payment rates for blood 
and blood products (which are generally identified with status 
indicator ``R'').
    For a more detailed discussion of payments for blood and blood 
products through APCs, we refer readers to:
    <bullet> the CY 2005 OPPS proposed rule (69 FR 50524 and 50525) for 
a more comprehensive discussion of the blood-specific CCR methodology;
    <bullet> the CY 2008 OPPS/ASC final rule with comment period (72 FR 
66807 through 66810) for a detailed history of the OPPS payment for 
blood and blood products; and
    <bullet> the CY 2015 OPPS/ASC final rule with comment period (79 FR 
66795 and 66796) for additional discussion of our policy not to make 
separate payments for blood and blood products when they appear on the 
same claims as services assigned to a C-APC.
(2) Brachytherapy Sources
    Section 1833(t)(2)(H) of the Act mandates the creation of 
additional groups of covered OPD services that classify devices of 
brachytherapy--cancer treatment through solid source radioactive 
implants--consisting of a seed or seeds (or radioactive source) 
(``brachytherapy sources'') separately from other services or groups of 
services. The statute provides certain criteria for the additional 
groups. For the history of OPPS payment for brachytherapy sources, we 
refer readers to prior OPPS final rules, such as the CY 2012 OPPS/ASC 
final rule with comment period (77 FR 68240 and 68241). As we have 
stated in prior OPPS updates, we believe that adopting the general OPPS 
prospective payment methodology for brachytherapy sources is 
appropriate for several reasons (77 FR 68240). The general OPPS 
methodology uses costs based on claims data to set the relative payment 
weights for hospital outpatient services. This payment methodology 
results in more consistent, predictable, and equitable payment amounts 
per source across hospitals by averaging the extremely high and low 
values, in contrast to payment based on hospitals' charges adjusted to 
costs. We believe that the OPPS methodology, as opposed to payment 
based on hospitals' charges adjusted to cost, also would provide 
hospitals with incentives for efficiency in the provision of 
brachytherapy services to Medicare beneficiaries. Moreover, this 
approach is consistent with our payment methodology for most items and 
services paid under the OPPS. We refer readers to the CY 2016 OPPS/ASC 
final rule with comment period (80 FR 70323 through 70325) for further 
discussion of the history of OPPS payment for brachytherapy sources.
    For CY 2026, except where otherwise indicated, we propose to 
continue our policy and use the costs derived from CY 2024 claims data 
to set the proposed CY 2026 payment rates for brachytherapy sources 
because we propose to use CY 2024 data to set the proposed payment 
rates for most other items and services that would be paid under the CY 
2026 OPPS. With the exception of the proposed payment rate for 
brachytherapy source C2645 (Brachytherapy planar source, palladium-103, 
per square millimeter) and the proposed payment rates for low-volume 
brachytherapy APCs discussed in section III.D. of this proposed rule, 
we propose to base the payment rates for brachytherapy sources on the 
geometric mean unit costs for each source, consistent with the 
methodology that we propose for other items and services paid under the 
OPPS, as discussed in section II.A.2. of this proposed rule. We also 
propose for CY 2026 and subsequent years to continue the other payment 
policies for

[[Page 33488]]

brachytherapy sources that we finalized and first implemented in the CY 
2010 OPPS/ASC final rule with comment period (74 FR 60537). For CY 2026 
and subsequent years, we propose to pay for the stranded and 
nonstranded not otherwise specified (NOS) codes, HCPCS codes C2698 
(Brachytherapy source, stranded, not otherwise specified, per source) 
and C2699 (Brachytherapy source, non-stranded, not otherwise specified, 
per source), at a rate equal to the lowest stranded or nonstranded 
prospective payment rate for such sources, respectively, on a per-
source basis (as opposed to, for example, per mCi), which is based on 
the policy we established in the CY 2008 OPPS/ASC final rule with 
comment period (72 FR 66785). For CY 2026 and subsequent years, we also 
propose to continue the policy we implemented in the CY 2010 OPPS/ASC 
final rule with comment period (74 FR 60537) regarding payment for new 
brachytherapy sources for which we have no claims data, for the same 
reasons we discussed in the CY 2008 OPPS/ASC final rule with comment 
period (72 FR 66786; which was delayed until January 1, 2010, by 
section 142 of Pub. L. 110-275). Specifically, this policy is intended 
to enable us to assign new HCPCS codes for new brachytherapy sources to 
their own APCs, with prospective payment rates set based on our 
consideration of external data and other relevant information regarding 
the expected costs of the sources to hospitals. The proposed CY 2026 
payment rates for brachytherapy sources are included in Addendum B to 
this proposed rule (which is available via the internet on the CMS 
website at <a href="https://www.cms.gov/medicare/payment/prospective-payment-systems/hospital-outpatient/regulations-notices">https://www.cms.gov/medicare/payment/prospective-payment-systems/hospital-outpatient/regulations-notices</a>) and identified with 
status indicator ``U (Brachytherapy Sources, Paid under OPPS; separate 
APC payment).''
    For CY 2018, we assigned status indicator ``U'' to HCPCS code C2645 
(Brachytherapy planar source, palladium-103, per square millimeter) in 
the absence of claims data and established a payment rate using 
external data (invoice price) at $4.69 per mm\2\ for the brachytherapy 
source's APC--APC 2648 (Brachytx planar, p-103) (82 FR 49233 through 
49244). For CY 2019, in the absence of sufficient claims data, we 
continued to establish a payment rate for C2645 at $4.69 per mm\2\ for 
APC 2648 (Brachytx planar, p-103) (83 FR 58834 through 58836). Our CY 
2018 claims data available for the CY 2020 OPPS/ASC final rule with 
comment period (84 FR 61142) included two claims with a geometric mean 
cost for HCPCS code C2645 of $1.02 per mm\2\. In response to comments 
from interested parties, we agreed that, given the limited claims data 
available and a new outpatient indication for C2645, a payment rate for 
HCPCS code C2645 based on the geometric mean cost of $1.02 per mm\2\ 
may not adequately reflect the cost of HCPCS code C2645. In the CY 2020 
OPPS/ASC final rule with comment period, we finalized our policy to use 
our equitable adjustment authority under section 1833(t)(2)(E) of the 
Act, which states that the Secretary shall establish, in a budget 
neutral manner, other adjustments as determined to be necessary to 
ensure equitable payments, to maintain the CY 2019 payment rate of 
$4.69 per mm\2\ for HCPCS code C2645 for CY 2020. Similarly, in the 
absence of sufficient claims data to establish an APC payment rate, in 
the CY 2021, CY 2022, CY 2023, CY 2024, and CY 2025 OPPS/ASC final 
rules with comment period (85 FR 85879 through 85880, 86 FR 63469, 87 
FR 71760-71761, 88 FR 81553, and 89 FR 93925), we finalized our policy 
to use our equitable adjustment authority under section 1833(t)(2)(E) 
of the Act to maintain the CY 2019 payment rate of $4.69 per mm\2\ for 
HCPCS code C2645 for CYs 2021 through 2025.
    There are no CY 2024 claims available that reported HCPCS code 
C2645 for this proposed rule. Therefore, in the absence of claims data, 
we propose to continue to use our equitable adjustment authority under 
section 1833(t)(2)(E) of the Act to maintain the CY 2025 payment rate 
of $4.69 per mm\2\ for HCPCS code C2645, which we propose to be 
assigned to APC 2648 (Brachytx planar, p-103), for CY 2026.
    Additionally, for CY 2022 and subsequent calendar years, we adopted 
a Universal Low Volume APC policy for clinical and brachytherapy APCs. 
As discussed in further detail in section X.C. of the CY 2022 OPPS/ASC 
final rule with comment period (86 FR 63743 through 63747), we adopted 
this policy to mitigate wide variation in payment rates that occur from 
year to year for APCs with low utilization. Such volatility in payment 
rates from year to year can result in even lower utilization and 
potential barriers to access. Brachytherapy APCs that have fewer than 
100 single claims used for ratesetting purposes are designated as Low 
Volume APCs unless an alternative payment rate is applied, such as the 
use of our equitable adjustment authority under section 1833(t)(2)(E) 
of the Act in the case of APC 2648 (Brachytx planar, p-103), for which 
HCPCS code C2645 (Brachytherapy planar source, palladium-103, per 
square millimeter) is the only code assigned as discussed previously in 
this section.
    For CY 2026, we propose to designate six brachytherapy APCs as Low 
Volume APCs as these APCs meet our criteria to be designated as Low 
Volume APCs. For more information on the brachytherapy APCs we propose 
to designate as Low Volume APCs, see section III.D. of this proposed 
rule.
    We invite interested parties to submit recommendations for new 
codes to describe new brachytherapy sources. Such recommendations 
should be directed via email to <a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="f69983828697829f939882868685b6959b85d89e9e85d8919980">[email&#160;protected]</a>. We will 
continue to add new brachytherapy source codes and descriptors to our 
systems for payment on a quarterly basis.
b. Comprehensive APCs (C-APCs) for CY 2026
(1) Background
    In the CY 2014 OPPS/ASC final rule with comment period (78 FR 74861 
through 74910), we finalized a comprehensive payment policy that 
packages payment for adjunctive and secondary items, services, and 
procedures into the most costly primary procedure under the OPPS at the 
claim level. The policy was finalized in CY 2014, but the effective 
date was delayed until January 1, 2015, to allow additional time for 
further analysis, opportunity for public comment, and systems 
preparation. The comprehensive APC (C-APC) policy was implemented 
effective January 1, 2015, with modifications and clarifications in 
response to public comments received regarding specific provisions of 
the C-APC policy (79 FR 66798 through 66810).
    A C-APC is defined as a classification for the provision of a 
primary service and all adjunctive services provided to support the 
delivery of the primary service. We established C-APCs as a category 
broadly for OPPS payment and implemented 25 C-APCs beginning in CY 2015 
(79 FR 66809 and 66810). We have gradually added new C-APCs since the 
policy was implemented beginning in CY 2015, with the number of C-APCs 
now totaling 72 (80 FR 70332; 81 FR 79584 and 79585; 83 FR 58844 
through 58846; 84 FR 61158 through 61166; 85 FR 85885; 86 FR 63474; 87 
FR 71769; 88 FR 81562; and 89 FR 93926).
    Under our C-APC policy, we designate a service described by a HCPCS 
code assigned to a C-APC as the primary service when the service is

[[Page 33489]]

identified by OPPS status indicator ``J1.'' When such a primary service 
is reported on a hospital outpatient claim, taking into consideration 
the few exceptions that are discussed below, we make payment for all 
other items and services reported on the hospital outpatient claim as 
being integral, ancillary, supportive, dependent, and adjunctive to the 
primary service (hereinafter collectively referred to as ``adjunctive 
services'') and representing components of a complete comprehensive 
service (78 FR 74865 and 79 FR 66799). Payments for adjunctive services 
are packaged into the payments for the primary services. This results 
in a single prospective payment for each of the primary, comprehensive 
services based on the costs of all reported services at the claim 
level. One example of a primary service would be a partial mastectomy, 
and an example of a secondary service packaged into that primary 
service would be a radiation therapy procedure.
    Services excluded from the C-APC policy under the OPPS include 
services that are not covered OPD services, services that cannot, by 
statute, be paid for under the OPPS, and services that are required by 
statute to be separately paid. This includes certain mammography and 
ambulance services that are not covered OPD services in accordance with 
section 1833(t)(1)(B)(iv) of the Act; brachytherapy seeds, which also 
are required by statute to receive separate payment under section 
1833(t)(2)(H) of the Act; pass-through payment drugs and devices, which 
also require separate payment under section 1833(t)(6) of the Act; 
self-administered drugs (SADs) that are not otherwise packaged as 
supplies because they are not covered under Medicare Part B under 
section 1861(s)(2)(B) of the Act; and certain preventive services (78 
FR 74865 and 79 FR 66800 and 66801). A list of services excluded from 
the C-APC policy is included in Addendum J to this proposed rule (which 
is available via the internet on the CMS website at <a href="https://www.cms.gov/medicare/payment/prospective-payment-systems/hospital-outpatient/regulations-notices">https://www.cms.gov/medicare/payment/prospective-payment-systems/hospital-outpatient/regulations-notices</a>). If a service does not appear on this 
list of excluded services, payment for it will be packaged into the 
payment for the primary C-APC service when it appears on an outpatient 
claim with a primary C-APC service.
    The C-APC policy payment methodology set forth in the CY 2014 OPPS/
ASC final rule with comment period and modified and implemented 
beginning in CY 2015 is summarized as follows (78 FR 74887 and 79 FR 
66800):
    Basic Methodology. As stated in the CY 2015 OPPS/ASC final rule 
with comment period, we define the C-APC payment policy as including 
all covered OPD services on a hospital outpatient claim reporting a 
primary service that is assigned to status indicator ``J1,'' \1\ 
excluding services that are not covered OPD services or that cannot by 
statute be paid for under the OPPS. Services and procedures described 
by HCPCS codes assigned to status indicator ``J1'' are assigned to C-
APCs based on our usual APC assignment methodology by evaluating the 
geometric mean costs of the primary service claims to establish 
resource similarity and the clinical characteristics of each procedure 
to establish clinical similarity within each APC.
---------------------------------------------------------------------------

    \1\ Status indicator ``J1'' denotes Hospital Part B Services 
Paid Through a Comprehensive APC. Further information can be found 
in CY 2026 Addendum D1.
---------------------------------------------------------------------------

    In the CY 2016 OPPS/ASC final rule with comment period, we expanded 
the C-APC payment methodology to qualifying extended assessment and 
management encounters through the ``Comprehensive Observation 
Services'' C-APC (C-APC 8011). Services within this APC are assigned 
status indicator ``J2.'' \2\ Specifically, we make a payment through C-
APC 8011 for a claim that:

That May Be Paid Through a Comprehensive APC. Further information 
can be found in CY 2026 Addendum D1.
---------------------------------------------------------------------------

    <bullet> Does not contain a procedure described by a HCPCS code to 
which we have assigned status indicator ``T;'' \3\
---------------------------------------------------------------------------

    \3\ Status Indicator ``T'' is defined as a ``Procedure or 
Service, Multiple Procedure Reduction Applies'' the OPPS payment 
status is ``Paid under OPPS; separate APC payment.'' Definitions to 
all OPPS payment status indicators are available in Addenda D1 to 
this proposed rule.
---------------------------------------------------------------------------

    <bullet> Contains 8 or more units of services described by HCPCS 
code G0378 (Hospital observation services, per hour);
    <bullet> Contains services provided on the same date of service or 
one day before the date of service for HCPCS code G0378 that are 
described by one of the following codes: HCPCS code G0379 (Direct 
admission of patient for hospital observation care) on the same date of 
service as HCPCS code G0378; CPT code 99281 (Emergency department visit 
for the evaluation and management of a patient (Level 1)); CPT code 
99282 (Emergency department visit for the evaluation and management of 
a patient (Level 2)); CPT code 99283 (Emergency department visit for 
the evaluation and management of a patient (Level 3)); CPT code 99284 
(Emergency department visit for the evaluation and management of a 
patient (Level 4)); CPT code 99285 (Emergency department visit for the 
evaluation and management of a patient (Level 5)) or HCPCS code G0380 
(Type B emergency department visit (Level 1)); HCPCS code G0381 (Type B 
emergency department visit (Level 2)); HCPCS code G0382 (Type B 
emergency department visit (Level 3)); HCPCS code G0383 (Type B 
emergency department visit (Level 4)); HCPCS code G0384 (Type B 
emergency department visit (Level 5)); CPT code 99291 (Critical care, 
evaluation and management of the critically ill or critically injured 
patient; first 30-74 minutes); or HCPCS code G0463 (Hospital outpatient 
clinic visit for assessment and management of a patient); and
    <bullet> Does not contain services described by a HCPCS code to 
which we have assigned status indicator ``J1.''
    The assignment of status indicator ``J2'' to a specific set of 
services performed in combination with each other allows for all other 
OPPS payable services and items reported on the claim (excluding 
services that are not covered OPD services or that cannot by statute be 
paid for under the OPPS) to be deemed adjunctive services representing 
components of a comprehensive service and resulting in a single 
prospective payment for the comprehensive service based on the costs of 
all reported services on the claim (80 FR 70333 through 70336).
    Services included under the C-APC payment packaging policy, that 
is, services that are typically adjunctive to the primary service and 
provided during the delivery of the comprehensive service, include 
diagnostic procedures, laboratory tests, and other diagnostic tests and 
treatments that assist in the delivery of the primary procedure; visits 
and evaluations performed in association with the procedure; uncoded 
services and supplies used during the service; durable medical 
equipment as well as prosthetic and orthotic items and supplies when 
provided as part of the outpatient service; and any other components 
reported by HCPCS codes that represent services that are provided 
during the complete comprehensive service (78 FR 74865 and 79 FR 
66800).
    In addition, payment for hospital outpatient department services 
that are similar to therapy services, such as speech language 
pathology, and delivered either by therapists or nontherapists is 
included as part of the payment for the packaged complete comprehensive 
service. These services that are provided during the perioperative 
period are adjunctive services and are deemed not to be therapy 
services as described in section

[[Page 33490]]

1834(k) of the Act, regardless of whether the services are delivered by 
therapists or other nontherapist health care workers. We have 
previously noted that therapy services are those provided by therapists 
under a plan of care in accordance with section 1835(a)(2)(C) and 
section 1835(a)(2)(D) of the Act and are paid for under section 1834(k) 
of the Act, subject to annual therapy caps as applicable (78 FR 74867 
and 79 FR 66800). However, certain other services similar to therapy 
services are considered and paid for as hospital outpatient department 
services. Payment for these nontherapy outpatient department services 
that are reported with therapy codes and provided with a comprehensive 
service is included in the payment for the packaged complete 
comprehensive service. We note that these services, even though they 
are reported with therapy codes, are hospital outpatient department 
services and not therapy services. We refer readers to the July 2016 
OPPS Change Request 9658 (Transmittal 3523) \4\ for further 
instructions on reporting these services in the context of a C-APC 
service.

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

    Items included in the packaged payment provided in conjunction with 
the primary service also include all drugs, biologicals, and 
radiopharmaceuticals, regardless of cost, except those drugs with pass-
through payment status and SADs, unless they function as packaged 
supplies (78 FR 74868, 74869, and 74909 and 79 FR 66800). We refer 
readers to Section 50.2M, Chapter 15, of the Medicare Benefit Policy 
Manual for a description of our policy on SADs treated as hospital 
outpatient supplies, including lists of SADs that function as supplies 
and those that do not function as supplies.\5\

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

    We define each hospital outpatient claim reporting a single unit of 
a single primary service assigned to status indicator ``J1'' as a 
single ``J1'' unit procedure claim (78 FR 74871 and 79 FR 66801). Line-
item charges for services included on the C-APC claim are converted to 
line-item costs, which are then summed to develop the estimated APC 
costs. These claims are then assigned one unit of the service with 
status indicator ``J1'' and later used to develop the geometric mean 
costs for the C-APC relative payment weights. (We note that we use the 
term ``comprehensive'' to describe the geometric mean cost of a claim 
reporting ``J1'' service(s) or the geometric mean cost of a C-APC, 
inclusive of all the items and services included in the C-APC service 
payment bundle.) Charges for services that would otherwise be 
separately payable are added to the charges for the primary service. 
This process differs from our traditional cost accounting methodology 
only in that all such services on the claim are packaged (except 
certain services as described above). We apply our standard data trims, 
which exclude claims with extremely high primary units or extreme 
costs.
    The comprehensive geometric mean costs are used to establish 
resource similarity and, along with clinical similarity, dictate the 
assignment of the primary services to the C-APCs. We establish a 
ranking of each primary service (single unit only) to be assigned to 
status indicator ``J1'' according to its comprehensive geometric mean 
costs. For the minority of claims reporting more than one primary 
service assigned to status indicator ``J1'' or units thereof, we 
identify one ``J1'' service as the primary service for the claim based 
on our cost-based ranking of primary services. We then assign these 
multiple ``J1'' procedure claims to the C-APC to which the service 
designated as the primary service is assigned. If the reported ``J1'' 
services on a claim map to different C-APCs, we designate the ``J1'' 
service assigned to the C-APC with the highest comprehensive geometric 
mean cost as the primary service for that claim. If the reported 
multiple ``J1'' services on a claim map to the same C-APC, we designate 
the most costly service (at the HCPCS code level) as the primary 
service for that claim. This process results in initial assignments of 
claims for the primary services assigned to status indicator ``J1'' to 
the most appropriate C-APCs based on both single and multiple procedure 
claims reporting these services and clinical and resource homogeneity.
    Complexity Adjustments. We use complexity adjustments to provide 
increased payment for certain comprehensive services. We apply a 
complexity adjustment by promoting qualifying paired ``J1'' service 
code combinations or paired code combinations of ``J1'' services and 
certain add-on codes (as described further below) from the originating 
C-APC (the C-APC to which the designated primary service is first 
assigned) to the next higher paying C-APC in the same clinical family 
of C-APCs. We apply this type of complexity adjustment when the paired 
code combination represents a complex, costly form or version of the 
primary service according to the following criteria:
    <bullet> Frequency of 25 or more claims reporting the code 
combination (frequency threshold); and
    <bullet> Violation of the 2 times rule, as stated in section 
1833(t)(2) of the Act and section III.B.2. of this proposed rule, in 
the originating C-APC (cost threshold).
    These criteria identify paired code combinations that occur 
commonly and exhibit materially greater resource requirements than the 
primary service. The CY 2017 OPPS/ASC final rule with comment period 
(81 FR 79582) included a revision to the complexity adjustment 
eligibility criteria. Specifically, we finalized a policy to 
discontinue the requirement that a code combination (that qualifies for 
a complexity adjustment by satisfying the frequency and cost criteria 
thresholds described above) also not create a 2 times rule violation in 
the higher level or receiving APC.
    After designating a single primary service for a claim, we evaluate 
that service in combination with each of the other procedure codes 
reported on the claim assigned to status indicator ``J1'' (or certain 
add-on codes) to determine if there are paired code combinations that 
meet the complexity adjustment criteria. For a new HCPCS code, we 
determine initial C-APC assignment and qualification for a complexity 
adjustment using the best available information, crosswalking the new 
HCPCS code to a predecessor code(s) when appropriate.
    Once we have determined that a particular code combination of 
``J1'' services (or combinations of ``J1'' services reported in 
conjunction with certain add-on codes) represents a complex version of 
the primary service because it is sufficiently costly, frequent, and a 
subset of the primary comprehensive service overall according to the 
criteria described above, we promote the claim including the complex 
version of the primary service as described by the code combination to 
the next higher cost C-APC within the clinical family, unless the 
primary service is already assigned to the highest cost APC within the 
C-APC clinical family or assigned to the only C-APC in a clinical 
family. We do not create new APCs with a comprehensive geometric mean 
cost that is higher than the highest geometric mean cost (or only) C-
APC in a clinical family just to accommodate potential complexity 
adjustments. Therefore, the highest payment for any claim including a 
code combination for services

[[Page 33491]]

assigned to a C-APC would be the highest paying C-APC in the clinical 
family (79 FR 66802).
    We package payment for all add-on codes into the payment for the C-
APC. However, certain primary service add-on combinations may qualify 
for a complexity adjustment. As noted in the CY 2016 OPPS/ASC final 
rule with comment period (80 FR 70331), all add-on codes that can be 
appropriately reported in combination with a base code that describes a 
primary ``J1'' service are evaluated for a complexity adjustment.
    To determine which combinations of primary service codes reported 
in conjunction with an add-on code may qualify for a complexity 
adjustment for CY 2026, we apply the frequency and cost criteria 
thresholds discussed above, testing claims reporting one unit of a 
single primary service assigned to status indicator ``J1'' and any 
number of units of a single add-on code for the primary ``J1'' service. 
If the frequency and cost criteria thresholds for a complexity 
adjustment are met and reassignment to the next higher cost APC in the 
clinical family is appropriate (based on meeting the criteria outlined 
above), we make a complexity adjustment for the code combination; that 
is, we reassign the primary service code reported in conjunction with 
the add-on code to the next higher cost C-APC within the same clinical 
family of C-APCs. As previously stated, we package payment for add-on 
codes into the C-APC payment rate. If any add-on code reported in 
conjunction with the ``J1'' primary service code does not qualify for a 
complexity adjustment, payment for the add-on service continues to be 
packaged into the payment for the primary service and is not reassigned 
to the next higher cost C-APC. We list the proposed complexity 
adjustments for ``J1'' and add-on code combinations for CY 2026, along 
with all the other proposed complexity adjustments, in Addendum J to 
this proposed rule (which is available via the internet on the CMS 
website at <a href="https://www.cms.gov/medicare/payment/prospective-payment-systems/hospital-outpatient/regulations-notices">https://www.cms.gov/medicare/payment/prospective-payment-systems/hospital-outpatient/regulations-notices</a>).
    Addendum J to this proposed rule includes the cost statistics for 
each code combination that would qualify for a complexity adjustment 
(including primary code and add-on code combinations). Addendum J to 
this proposed rule also contains summary cost statistics for each of 
the paired code combinations that describe a complex code combination 
that would qualify for a complexity adjustment and be reassigned to the 
next higher cost C-APC within the clinical family. The combined 
statistics for all proposed reassigned complex code combinations are 
represented by an alphanumeric code with the first four digits of the 
designated primary service followed by a letter. For example, the 
proposed geometric mean cost listed in Addendum J for the code 
combination described by complexity adjustment assignment 3320R, which 
is assigned to C-APC 5224 (Level 4 Pacemaker and Similar Procedures), 
includes all paired code combinations that will be reassigned to C-APC 
5224 when CPT code 33208 is the primary code. Providing the information 
contained in Addendum J to this proposed rule allows interested parties 
the opportunity to better assess the impact associated with the 
assignment of claims with each of the paired code combinations eligible 
for a complexity adjustment.
(2) Comment Solicitation on C-APC Complexity Adjustment Criteria
    We have received a variety of requests from interested parties as 
well, as public comments in past rulemaking, related to our C-APC 
complexity adjustment criteria. Interested parties and commenters have 
requested that CMS modify the established C-APC complexity adjustment 
eligibility criteria of 25 or more claims reporting the code 
combination (frequency threshold) and a violation of the 2 times rule 
in the originating C-APC (cost threshold) to allow additional code 
combinations to qualify for complexity adjustments. Interested parties 
and commenters have also requested expanding the qualifying code 
combinations for complexity adjustments to allow clusters of 
procedures, consisting of a ``J1'' code pair and multiple other 
associated add-on codes, to be used in combination with that ``J1'' 
code pair to qualify. These interested parties and commenters have 
noted these expanded combinations may allow for a more accurate 
reflection of medical practice when multiple procedures are performed 
together or there are certain complex procedures that include numerous 
add-on codes.
    For CY 2026, we are soliciting comments on potential refinements to 
our C-APC complexity adjustment criteria. Under this solicitation, we 
are seeking comment on expanding code combinations that qualify for 
complexity adjustments, including any specifications related to 
determining specific combination types and how they represent a 
complex, costly subset of the primary service. We are seeking comment 
on how CMS could identify service pairings or clusters of services for 
complexity adjustments that are clinically appropriate but are 
currently not evaluated for complexity adjustments. Additionally, if we 
were to expand our complexity adjustment criteria to allow for clusters 
of codes, we are seeking comment on what the appropriate cost and 
frequency thresholds could be used to identify which code clusters 
truly reflect complex and resource-intensive code combinations that are 
commonly performed in the hospital outpatient department setting.
    We are seeking comment on which services are clinically integral to 
the provision of ``J1'' services that would qualify for a complexity 
adjustment under an expanded evaluation framework. Specifically, we are 
seeking comment on what criteria we could add, reflecting clinical 
practice, that would determine the costly additional components that 
are often associated with other high-cost packaged items and services. 
Finally, we are seeking comment on how we might address the unintended 
consequences of granular coding on the mechanics of the complexity 
adjustment criteria and if highly specific coding truly reflects 
clinical practice in hospital outpatient departments.
(3) Exclusion of Procedures Assigned to New Technology APCs From the C-
APC Policy
    Services that are assigned to New Technology APCs are typically new 
procedures that do not have sufficient claims history to establish an 
accurate payment for them. Beginning in CY 2002, we retain services 
within New Technology APC groups until we gather sufficient claims data 
to enable us to assign the service to an appropriate clinical APC. This 
policy allows us to move a service from a New Technology APC in less 
than 2 years if sufficient data are available. It also allows us to 
retain a service in a New Technology APC for more than 2 years if 
sufficient data upon which to base a decision for reassignment have not 
been collected (82 FR 59277).
    The C-APC payment policy packages payment for adjunctive and 
secondary items, services, and procedures into the most costly primary 
procedure under the OPPS at the claim level. Prior to CY 2019, when a 
procedure assigned to a New Technology APC was included on the claim 
with a primary procedure, identified by OPPS status indicator ``J1,'' 
payment for the new technology service was typically packaged into the 
payment for the primary procedure.

[[Page 33492]]

Because the new technology service was not separately paid in this 
scenario, the overall number of single claims available to determine an 
appropriate clinical APC for the new service was reduced. This was 
contrary to the objective of the New Technology APC payment policy, 
which is to gather sufficient claims data to enable us to assign the 
service to an appropriate clinical APC.
    To address this issue and ensure that there are sufficient claims 
data for services assigned to New Technology APCs, in the CY 2019 OPPS/
ASC final rule with comment period (83 FR 58847), we finalized 
excluding payment for any procedure that is assigned to a New 
Technology APC (APCs 1491 through 1599 and APCs 1901 through 1908) from 
being packaged when included on a claim with a ``J1'' service assigned 
to a C-APC. In the CY 2020 OPPS/ASC final rule with comment period, we 
finalized that beginning in CY 2020, payment for services assigned to a 
New Technology APC would be excluded from being packaged into the 
payment for comprehensive observation services assigned status 
indicator ``J2'' when they are included on a claim with a ``J2'' 
service (84 FR 61167).
(4) Exclusion of Drugs and Biologicals Described by HCPCS Code C9399 
(Unclassified Drugs or Biologicals) From the C-APC Policy
    Section 1833(t)(15) of the Act, as added by section 621(a)(1) of 
the Medicare Prescription Drug, Improvement, and Modernization Act of 
2003 (Pub. L. 108-173), provides for payment under the OPPS for new 
drugs and biologicals until HCPCS codes are assigned. Under this 
provision, we are required to make payment for a covered outpatient 
drug or biological that is furnished as part of covered outpatient 
department services but for which a HCPCS code has not yet been 
assigned in an amount equal to 95 percent of average wholesale price 
(AWP) for the drug or biological.
    In the CY 2005 OPPS/ASC final rule with comment period (69 FR 
65805), we implemented section 1833(t)(15) of the Act by instructing 
hospitals to bill for a drug or biological that is newly approved by 
the Food and Drug Administration (FDA) and that does not yet have a 
HCPCS code by reporting the National Drug Code (NDC) for the product 
along with the newly created HCPCS code C9399 (Unclassified drugs or 
biologicals). We explained that when HCPCS code C9399 appears on a 
claim, the Outpatient Code Editor (OCE) suspends the claim for manual 
pricing by the Medicare Administrative Contractor (MAC). The MAC prices 
the claim at 95 percent of the drug or biological's AWP, using Red Book 
or an equivalent recognized compendium, and processes the claim for 
payment. We emphasized that this approach enables hospitals to bill and 
receive payment for a new drug or biological concurrent with its 
approval by the FDA. The hospital does not have to wait for the next 
quarterly release or for approval of a product specific HCPCS code to 
receive payment for a newly approved drug or biological or to resubmit 
claims for adjustment. We instructed that hospitals would discontinue 
billing HCPCS code C9399 and the NDC upon implementation of a product 
specific HCPCS code, status indicator, and appropriate payment amount 
with the next quarterly update. We also note that HCPCS code C9399 is 
paid in a similar manner in the ASC setting, as 42 CFR 416.171(b) 
outlines that certain drugs and biologicals for which separate payment 
is allowed under the OPPS are considered covered ancillary services for 
which the OPPS payment rate, which is 95 percent of AWP for HCPCS code 
C9399, applies. Since the implementation of the C-APC policy in 2015, 
payment for drugs and biologicals described by HCPCS code C9399 had 
been included in the C-APC payment when these products appear on a 
claim with a primary C-APC service. Packaging payment for these drugs 
and biologicals that appear on a hospital outpatient claim with a 
primary C-APC service is consistent with our C-APC packaging policy 
under which we make payment for all items and services, including all 
non-pass-through drugs, reported on the hospital outpatient claim as 
being integral, ancillary, supportive, dependent, and adjunctive to the 
primary service and representing components of a complete comprehensive 
service, with certain limited exceptions (78 FR 74869). It was our 
position that the total payment for the C-APC with which payment for a 
drug or biological described by HCPCS code C9399 is packaged includes 
payment for the drug or biological at 95 percent of its AWP.
    However, we determined that in certain instances, drugs and 
biologicals described by HCPCS code C9399 are not being paid at 95 
percent of their AWPs when payment for them is packaged with payment 
for a primary C-APC service. In order to ensure payment for new drugs 
and biologicals described by HCPCS code C9399 at 95 percent of their 
AWP, for CY 2023 and subsequent years, we finalized our proposal to 
exclude any drug or biological described by HCPCS code C9399 from 
packaging when the drug or biological is included on a claim with a 
``J1'' service, which is the status indicator assigned to a C-APC, and 
a claim with a ``J2'' service, which is the status indicator assigned 
to comprehensive observation services. See Addendum J to this proposed 
rule for the proposed CY 2026 C-APC payment policy exclusions.
    In the CY 2023 OPPS/ASC final rule with comment period, we 
finalized the proposal in section XI., ``CY 2023 OPPS Payment Status 
and Comment Indicators'', to add a new definition to status indicator 
``A'' to include unclassified drugs and biologicals that are reportable 
with HCPCS code C9399 (87 FR 72051). The current definition, as 
finalized in the CY 2023 OPPS/ASC final rule with comment period, can 
be found in Addendum D1 of this proposed rule, would ensure the MAC 
prices claims for drugs or biologicals billed with HCPCS code C9399 at 
95 percent of the drug or biological's AWP and pays separately for the 
drug or biological under the OPPS when it appears on the same claim as 
a primary C-APC service.
(5) Exclusion of Cell and Gene Therapies From the C-APC Policy
    As previously discussed in this section, and in the CY 2014 OPPS/
ASC final rule with comment period (78 FR 74865), the C-APC policy 
packages payment for items and services that are typically integral, 
ancillary, supportive, dependent, or adjunctive to the primary service 
and provided during the delivery of the comprehensive service, 
including diagnostic procedures, laboratory tests and other diagnostic 
tests and treatments that assist in the delivery of the primary 
procedure. In the CY 2014 OPPS/ASC final rule with comment period (78 
FR 74861), we finalized defining a comprehensive APC as a 
classification for the provision of a primary service and all 
adjunctive services provided to support the delivery of the primary 
service. Because a comprehensive APC treats all individually reported 
codes as representing components of the comprehensive service, we make 
a single prospective payment based on the cost of all individually 
reported codes that represent the provision of a primary service and 
all adjunctive services provided to support that delivery of the 
primary service.
    As discussed in the CY 2025 OPPS/ASC proposed rule (89 FR 59201 
through 59204), we generally treat all items and services reported on a 
C-APC claim as integral, ancillary, supportive, dependent, and 
adjunctive to the

[[Page 33493]]

primary service and representing components of a comprehensive service. 
Historically, items packaged for payment provided in conjunction with 
the primary C-APC service also include all drugs, biologicals, and 
radiopharmaceuticals, regardless of cost, except those drugs with pass-
through payment status and those drugs that are usually self-
administered (SADs), unless they function as supplies (78 FR 74868 
through 74869 and 74909).
    However, we recognized in the 2025 OPPS/ASC proposed rule (89 FR 
59201 through 59204) that there are rare instances in which cell and 
gene therapies appear on the same claim as a primary C-APC service and 
therefore, have their payment packaged with payment for the primary C-
APC service. As stated in the CY 2025 OPPS/ASC final rule with comment 
period (89 FR 93932 through 93938), given the unique nature of these 
therapies, we do not believe they function as integral, ancillary, 
supportive, dependent, or adjunctive to any of the current primary C-
APC services. Additionally, we stated that when these products are 
administered, they are the primary treatment being administered to a 
patient and thus, are not integral, ancillary, supportive, dependent, 
or adjunctive to any primary C-APC services.
    Therefore, we finalized a policy for CY 2025 and subsequent years 
(89 FR 93932 through 93938), to not package payment for cell and gene 
therapies into C-APCs, when those cell and gene therapies are not 
functioning as integral, ancillary, supportive, dependent, or 
adjunctive to the primary C-APC service. For new cell and gene therapy 
products that are not integral, ancillary, supportive, dependent, or 
adjunctive to any C-APC primary service, we will continue to add their 
product specific HCPCS codes, when created, to the C-APC exclusion 
list. The current list of qualifying products can be found in Table 1.
    We list all proposed C-APC exclusion categories for CY 2026 in 
Addendum J to this proposed rule (which is available via the internet 
on the CMS website at <a href="https://www.cms.gov/medicare/payment/prospective-payment-systems/hospital-outpatient/regulations-notices">https://www.cms.gov/medicare/payment/prospective-payment-systems/hospital-outpatient/regulations-notices</a>).

(6) Exclusion of Non-Opioid Products for Pain Relief Under Section 4135 
of the Consolidated Appropriations Act, 2023 From the C-APC Policy
    The Consolidated Appropriations Act (CAA), 2023 (Pub. L. 117-328), 
was signed into law on December 29, 2022. Section 4135(a) and (b) of 
the CAA, 2023, titled ``Access to Non-Opioid Treatments for Pain 
Relief,'' amended section 1833(t)(16) and section 1833(i) of the Social 
Security Act, respectively, to provide for temporary additional 
payments for non-opioid treatments for pain relief (as that term is 
defined in section 1833(t)(16)(G)(i) of the Act). In particular, 
section 1833(t)(16)(G) provides that with respect to a non-opioid 
treatment for pain relief furnished on or after January 1, 2025, and 
before January 1, 2028, the Secretary shall not package payment for the 
non-opioid treatment for pain relief into payment for a covered OPD 
service (or group of services) and shall make an additional payment for 
the non-opioid treatment for pain relief as specified in clause (ii) of 
that section. Clauses (ii) and (iii) of section 1833(t)(16)(G) of the 
Act provide for the amount of additional payment and set a limitation 
on that amount. As stated earlier in this section, our current policy 
is to exclude from the packaged C-APC payment those items and services 
that are required by statute to be separately paid.
    Accordingly, in the CY 2025 OPPS/ASC final rule with comment 
period, we finalized a policy to exclude the non-opioid treatments for 
pain relief identified as satisfying the required criteria for payment 
under section 4135 of the CAA, 2023 from the C-APC policy to ensure 
payment is not packaged into any C-APC and that separate payment is 
made in accordance with the statute (89 FR 93938 through 93939).
(7) C-APCs for CY 2026
    For CY 2026 and subsequent years, we propose to continue to apply 
the C-APC payment policy methodology. We refer readers to the CY 2017 
OPPS/ASC final rule with comment period (81 FR 79583) for a discussion 
of the C-APC payment policy methodology and revisions.
    Each year, in accordance with section 1833(t)(9)(A) of the Act, we 
review and revise the services within each APC group and the APC 
assignments under the OPPS. As a result of our annual review of the 
services and the APC assignments under the OPPS, we are not proposing 
to convert any standard APCs to C-APCs in CY 2026; thus, we propose 
that the number of C-APCs for CY 2026 would be the same as the number 
for CY 2025, which is 72 C-APCs.
    Table 2 lists the proposed C-APCs for CY 2026, all of which were 
established in past rules. All C-APCs are displayed in Addendum J to 
this proposed rule. Addendum J to this proposed rule also contains all 
the data related to the C-APC payment policy methodology, including the 
list of complexity adjustments and other information.

c. Calculation of Composite APC Criteria-Based Costs
    As discussed in the CY 2008 OPPS/ASC final rule with comment period 
(72 FR 66613), we believe it is important that the OPPS enhance 
incentives for hospitals to provide necessary, high-quality care as 
efficiently as possible. For CY 2008, we developed composite APCs to 
provide a single payment for groups of services that are typically 
performed together during a single clinical encounter and that result 
in the provision of a complete service. Combining payment for multiple, 
independent services into a single OPPS payment in this way enables 
hospitals to manage their resources with

[[Page 33497]]

maximum flexibility by monitoring and adjusting the volume and 
efficiency of services themselves. An additional advantage to the 
composite APC model is that we can use data from correctly coded 
multiple procedure claims to calculate payment rates for the specified 
combinations of services, rather than relying upon single procedure 
claims which may be low in volume and/or incorrectly coded. Under the 
OPPS, we currently have composite policies for mental health services 
and multiple imaging services. We refer readers to the CY 2008 OPPS/ASC 
final rule with comment period (72 FR 66611 through 66614 and 66650 
through 66652) for a full discussion of the development of the 
composite APC methodology, and the CY 2012 OPPS/ASC final rule with 
comment period (76 FR 74163) and the CY 2018 OPPS/ASC final rule with 
comment period (82 FR 59241, 59242, and 59246 through 52950) for 
further background.
(1) Mental Health Services Composite APC
    For CY 2026, we propose to continue our longstanding policy of 
limiting the aggregate payment for specified less resource-intensive 
mental health services furnished on the same date to the payment for a 
day of partial hospitalization services provided by a hospital, which 
we consider to be the most resource-intensive of all outpatient mental 
health services (88 FR 49572). We refer readers to the April 7, 2000, 
OPPS final rule with comment period (65 FR 18452 through 18455) for the 
initial discussion of this longstanding policy and the CY 2012 OPPS/ASC 
final rule with comment period (76 FR 74168) for further background.
    In the CY 2018 OPPS/ASC proposed rule and final rule with comment 
period (82 FR 33580 and 33581 and 82 FR 59246 and 59247), we proposed 
and finalized the policy for CY 2018 and subsequent years that, when 
the aggregate payment for specified mental health services provided by 
one hospital to a single beneficiary on a single date of service, based 
on the payment rates associated with the APCs for the individual 
services, exceeds the maximum per diem payment rate for partial 
hospitalization services provided by a hospital, those specified mental 
health services will be paid through composite APC 8010 (Mental Health 
Services Composite). In addition, we set the payment rate for composite 
APC 8010 for CY 2018 at the same payment rate for APC 5863, which was 
the maximum partial hospitalization per diem payment rate for a 
hospital, and finalized a policy that the hospital would continue to be 
paid the payment rate for composite APC 8010. This policy applied in 
CYs 2018 through 2023.
    In the CY 2024 OPPS/ASC proposed rule, we stated that APC 5863 was 
no longer the maximum partial hospitalization per diem payment rate for 
a hospital due to the creation of APC 5864, which is four or more 
hospital-based PHP services per day (88 FR 49572). We solicited comment 
on whether APC 5864 would be appropriate to use as the daily mental 
health cap, as we have historically set the daily mental health cap for 
composite APC 8010 at the maximum partial hospitalization per diem 
payment rate for a hospital (88 FR 49572). Based on public comments 
received and our longstanding policy, in CY 2024 OPPS/ASC final rule, 
we finalized APC 5864, four hospital-based PHP services per day, as the 
daily mental health cap (88 FR 81566).
    We continue to believe that the costs associated with administering 
a partial hospitalization program represent the most resource intensive 
of all outpatient mental health services. For CY 2026 and subsequent 
years, we propose to continue this policy that when the aggregate 
payment for specified mental health services provided by one hospital 
to a single beneficiary on a single date of service, based on the 
payment rates associated with the APCs for the individual services, 
exceeds the per diem payment rate for 4 partial hospitalization 
services provided in a day by a hospital (the payment amount for APC 
5864), those specified mental health services would be paid through 
composite APC 8010. In addition, we propose to continue to set the 
payment rate for composite APC 8010 at the same payment rate that we 
propose for APC 5864, which is a partial hospitalization per diem 
payment rate for 4 partial hospitalization services furnished in a day 
by a hospital.
    Under the proposed policy, the Integrated OCE (I/OCE) would 
continue to determine whether to pay for these specified mental health 
services individually, or to make a single payment at the same payment 
rate established for APC 5864 for all the specified mental health 
services furnished by the hospital on that single date of service by 
paying for the services through composite APC 5863.
(2) Multiple Imaging Composite APCs (APCs 8004, 8005, 8006, 8007, and 
8008)
    Effective January 1, 2009, we provide a single payment each time a 
hospital submits a claim for more than one imaging procedure within an 
imaging family on the same date of service, to reflect and promote the 
efficiencies hospitals can achieve when performing multiple imaging 
procedures during a single session (73 FR 41448 through 41450). We 
utilize three imaging families based on imaging modality for purposes 
of this methodology: (1) ultrasound; (2) computed tomography (CT) and 
computed tomographic angiography (CTA); and (3) magnetic resonance 
imaging (MRI) and magnetic resonance angiography (MRA). The HCPCS codes 
subject to the multiple imaging composite policy and their respective 
families are listed in Table 3.
    While there are three imaging families, there are five multiple 
imaging composite APCs due to the statutory requirement under section 
1833(t)(2)(G) of the Act that we differentiate payment for OPPS imaging 
services provided with and without contrast. While the ultrasound 
procedures included under the policy do not involve contrast, both CT/
CTA and MRI/MRA scans can be provided either with or without contrast. 
The five multiple imaging composite APCs established in CY 2009 are:
    <bullet> APC 8004 (Ultrasound Composite);
    <bullet> APC 8005 (CT and CTA without Contrast Composite);
    <bullet> APC 8006 (CT and CTA with Contrast Composite);
    <bullet> APC 8007 (MRI and MRA without Contrast Composite); and
    <bullet> APC 8008 (MRI and MRA with Contrast Composite).
    We define the single imaging session for the ``with contrast'' 
composite APCs as having at least one or more imaging procedures from 
the same family performed with contrast on the same date of service. 
For example, if the hospital performs an MRI without contrast during 
the same session as at least one other MRI with contrast, the hospital 
will receive payment based on the payment rate for APC 8008, the ``with 
contrast'' composite APC.
    We make a single payment for those imaging procedures that qualify 
for payment based on the composite APC payment rate, which includes any 
packaged services furnished on the same date of service. The standard 
(noncomposite) APC assignments continue to apply for single imaging 
procedures and multiple imaging procedures performed across families. 
For a full discussion of the development of the multiple imaging 
composite APC methodology, we refer readers to the CY 2009 OPPS/ASC 
final rule with comment period (73 FR 68559 through 68569).

[[Page 33498]]

    For CY 2026, we propose to continue to pay for all multiple imaging 
procedures within an imaging family performed on the same date of 
service using the multiple imaging composite APC payment methodology. 
We continue to believe that this policy would reflect and promote the 
efficiencies hospitals can achieve when performing multiple imaging 
procedures during a single session.
    For CY 2026, except where otherwise indicated, we propose to use 
the costs derived from CY 2024 claims data to set the proposed CY 2026 
payment rates. Therefore, for CY 2026, the proposed payment rates for 
the five multiple imaging composite APCs (APCs 8004, 8005, 8006, 8007, 
and 8008) were based on proposed geometric mean costs calculated from 
CY 2024 claims available for the CY 2026 OPPS/ASC proposed rule that 
qualify for composite payment under the current policy (that is, those 
claims reporting more than one procedure within the same family on a 
single date of service). To calculate the proposed geometric mean 
costs, we used the same methodology that we used to calculate the 
geometric mean costs for these composite APCs since CY 2014, as 
described in the CY 2014 OPPS/ASC final rule with comment period (78 FR 
74918). The imaging HCPCS codes referred to as ``overlap bypass codes'' 
that we removed from the bypass list for purposes of calculating the 
proposed multiple imaging composite APC geometric mean costs, in 
accordance with our established methodology as stated in the CY 2014 
OPPS/ASC final rule with comment period (78 FR 74918), are identified 
by asterisks in Addendum N to this proposed rule (which is available 
via the internet on the CMS website <a href="https://www.cms.gov/medicare/payment/prospective-payment-systems/hospital-outpatient/regulations-notices">https://www.cms.gov/medicare/payment/prospective-payment-systems/hospital-outpatient/regulations-notices</a>) and are discussed in more detail in section II.A.1.a. of this 
proposed rule.
    For this proposed rule, we were able to identify approximately 0.98 
million ``single session'' claims out of an estimated 2.2 million 
potential claims for payment through composite APCs from our 
ratesetting claims data, which represents approximately 44.0 percent of 
all eligible claims, to calculate the proposed CY 2026 geometric mean 
costs for the multiple imaging composite APCs. Table 3 lists the 
proposed HCPCS codes that would be subject to the multiple imaging 
composite APC policy and their respective families and approximate 
composite APC final geometric mean costs for CY 2026.

BILLING CODE 4120-01-C
3. Proposed Changes to Packaged Items and Services
a. Background and Rationale for Packaging in the OPPS
    Like other prospective payment systems, the OPPS relies on the 
concept of averaging to establish a payment rate for services. The 
payment may be more or less than the estimated cost of providing a 
specific service or a bundle of specific services for a particular 
beneficiary. The OPPS packages payments for multiple interrelated items 
and services into a single payment to create incentives for hospitals 
to furnish services most efficiently and to manage their resources with 
maximum flexibility. Our packaging policies support our strategic goal 
of using larger payment bundles in the OPPS to maximize hospitals' 
incentives to provide care in the most efficient

[[Page 33503]]

manner. For example, where there are a variety of devices, drugs, 
items, and supplies that could be used to furnish a service, some of 
which are more costly than others, packaging encourages hospitals to 
use the most cost-efficient item that meets the patient's needs, rather 
than to routinely use a more expensive item, which may occur if 
separate payment is provided for the item.
    Packaging also encourages hospitals to effectively negotiate with 
manufacturers and suppliers to reduce the purchase price of items and 
services or to explore alternative group purchasing arrangements, 
thereby encouraging the most economical health care delivery. 
Similarly, packaging encourages hospitals to establish protocols that 
ensure that necessary services are furnished, while scrutinizing the 
services ordered by practitioners to maximize the efficient use of 
hospital resources. Packaging payments into larger payment bundles 
promotes the predictability and accuracy of payment for services over 
time. Finally, packaging may reduce the importance of refining service-
specific payments because packaged payments include costs associated 
with higher cost cases requiring many ancillary items and services and 
lower cost cases requiring fewer ancillary items and services. 
Packaging encourages efficiency and is an essential component of a 
prospective payment system; therefore, packaging payments for items and 
services that are typically integral, ancillary, supportive, dependent, 
or adjunctive to a primary service has been a fundamental part of the 
OPPS since its implementation in August 2000. As we continue to develop 
larger payment groups that more broadly reflect services provided in an 
encounter or episode of care, we have expanded the OPPS packaging 
policies. Most, but not necessarily all, categories of items and 
services currently packaged in the OPPS are listed in 42 CFR 419.2(b). 
Our overarching goal is to make payments for all services under the 
OPPS more consistent with those of a prospective payment system and 
less like those of a per-service fee schedule, which pays separately 
for each coded item. As a part of this effort, we have continued to 
examine the payment for items and services provided under the OPPS to 
determine which OPPS services can be packaged to further achieve the 
objective of advancing the OPPS toward a more prospective payment 
system.
b. Proposed CY 2026 Policy on Packaged Items and Services
    For CY 2026, we examined the items and services currently provided 
under the OPPS, reviewing categories of integral, ancillary, 
supportive, dependent, or adjunctive items and services for which we 
believe payment would be appropriately packaged into payment for the 
primary service that they support. Specifically, we examined the HCPCS 
code definitions (including CPT code descriptors) and hospital 
outpatient department billing patterns to determine whether there were 
categories of codes for which packaging would be appropriate according 
to existing OPPS packaging policies or a logical expansion of those 
existing OPPS packaging policies.
    For CY 2026, we are not proposing any changes to the overall 
packaging policy discussed. We propose to continue to conditionally 
package the costs of selected newly identified ancillary services into 
payment for a primary service where we believe that the packaged item 
or service is integral, ancillary, supportive, dependent, or adjunctive 
to the provision of care that was reported by the primary service HCPCS 
code.
c. Payment for Diagnostic Radiopharmaceuticals
(1) Background on OPPS Packaging Policy for Diagnostic 
Radiopharmaceuticals
    Under the OPPS, we package several categories of nonpass-through 
drugs, biologicals, and radiopharmaceuticals, regardless of the cost of 
the products. Because the products are packaged according to the 
policies in Sec.  419.2(b), we refer to them as ``policy-packaged'' 
drugs, biologicals, and radiopharmaceuticals. In particular, under 
Sec.  419.2(b)(15), payment for drugs, biologicals, and, prior to CY 
2025, all radiopharmaceuticals that function as supplies when used in a 
diagnostic test or procedure are packaged with the payment for the 
related procedure or service. Packaging costs into a single aggregate 
payment for a service, encounter, or episode of care is a fundamental 
principle that distinguishes a prospective payment system from a fee 
schedule. In general, packaging the costs of supportive items and 
services into the payment for the primary procedure or service with 
which they are associated encourages hospital efficiencies and enables 
hospitals to manage their resources with maximum flexibility.
    In the CY 2008 OPPS/ASC final rule with comment period, we 
finalized the packaging status of diagnostic radiopharmaceuticals as 
part of our overall enhanced packaging approach for the CY 2008 OPPS 
and subsequent years (72 FR 66635 through 66641). Importantly, we noted 
that we believe diagnostic radiopharmaceuticals are always intended to 
be used with a diagnostic nuclear medicine procedure and function as 
supplies when used in a diagnostic test or procedure, making it 
appropriate to package the payment for the diagnostic 
radiopharmaceutical into the payment for the related nuclear medicine 
procedure. Higher cost diagnostic radiopharmaceuticals were one 
specific type of product that, prior to CY 2025, was policy packaged 
under the category described by Sec.  419.2(b)(15). Since we 
implemented this policy in CY 2008, interested parties raised concerns 
regarding policy packaging of diagnostic radiopharmaceuticals.
    In the CY 2025 OPPS/ASC proposed rule (89 FR 59213 through 59222), 
we stated that we continue to believe diagnostic radiopharmaceuticals 
are always intended to be used with a diagnostic nuclear medicine 
procedure and function as supplies when used in a diagnostic test or 
procedure, generally making it appropriate to package payment for them 
with payment for the related nuclear medicine procedure. However, we 
stated there are certain situations in which the packaged payment 
amount attributed to the diagnostic radiopharmaceutical used in an 
imaging procedure assigned to a nuclear medicine APC may not adequately 
account for the cost of a diagnostic radiopharmaceutical that has a 
significantly higher cost, but lower utilization relative to the other 
diagnostic radiopharmaceuticals that may be used with the procedure.
    In the CY 2025 OPPS/ASC final rule with comment period (89 FR 93948 
through 93963) we finalized a policy to pay separately for any 
diagnostic radiopharmaceutical with a per day cost greater than $630 
for CY 2025. We propose to use the same methodology that was finalized 
in the CY 2025 OPPS/ASC final rule with comment period in order to 
calculate the per day costs for diagnostic radiopharmaceuticals for CY 
2026 and future years (89 FR 93953 through 93955). We noted that any 
diagnostic radiopharmaceutical with a per day cost at or below that 
threshold will continue to be policy packaged under our longstanding 
policy at Sec.  419.2(b)(15). Additionally, we finalized the policy 
that starting in CY 2026 and for subsequent years, we will update the 
threshold amount of $630 by a forecast of the Producer Price Index 
(PPI) for Pharmaceuticals for Human

[[Page 33504]]

Use, Prescription (Bureau of Labor Statistics (BLS) series code 
WPUSI07003) from IHS Global, Inc (IGI) (89 FR 93955).
    In the CY 2025 OPPS/ASC final rule with comment period, we also 
finalized a policy to pay for nonpass-through, separately payable 
diagnostic radiopharmaceuticals with per day costs above the designated 
threshold based on our authority under section 1833(t)(14)(A)(iii)(II) 
of the Act. As we found that the ASP data we had was not usable for the 
purpose of paying for diagnostic radiopharmaceuticals, we finalized a 
policy to pay for qualifying nonpass-through diagnostic 
radiopharmaceuticals with claims data based on mean unit cost data 
derived from hospital claims. Additionally, we finalized corresponding 
modifications to the regulation text at Sec.  419.2(b)(15) and Sec.  
419.41 to codify our finalized payment policy for diagnostic 
radiopharmaceuticals and our existing policy for therapeutic 
radiopharmaceuticals. For additional information regarding the policy 
finalized for CY 2025, reference 89 FR 93948 through 93963.
(2) Proposed Diagnostic Radiopharmaceutical Packaging Threshold
    For CY 2026, we propose to continue the policy finalized in CY 
2025. Specifically, we propose to continue to calculate the per day 
cost of diagnostic radiopharmaceuticals based on the methodology 
described in section V.B.1.b. of this proposed rule, which relies on 
the methodology finalized in the CY 2006 OPPS final rule with comment 
period (70 FR 68636 through 68638).
    As finalized in the CY 2025 OPPS/ASC final rule with comment period 
(89 FR 93955), starting in the OPPS/ASC rulemaking for CY 2026 and for 
subsequent years, we stated we would update the proposed threshold 
amount of $630 by a forecast of the PPI for Pharmaceuticals for Human 
Use, Prescription (BLS series code WPUSI07003) from IHS Global, Inc 
(IGI) by using most recently available four-quarter moving average PPI 
levels to trend from the third quarter of the year 2 years prior to the 
applicable calendar year to the third quarter of the year prior to the 
applicable calendar year (for example, from the third quarter of 2024 
to the third quarter of 2025 for CY 2026). We propose a technical 
refinement to this policy. We propose to use the most recently 
available four-quarter moving average PPI levels to trend the CY 2025 
final threshold forward from the third quarter of the CY 2025 to the 
third quarter of the payment year (CY 2026) and round the resulting 
dollar amount to the nearest $5 increment. We believe using the most 
recently available four-quarter moving average PPI levels more 
appropriately updates the packaging threshold from CY 2025 for payment 
in CY 2026. For CY 2027 and subsequent updates, we therefore, propose 
to trend the CY 2025 threshold of $630 forward using the four-quarter 
moving average PPI levels for Pharmaceuticals for Human Use, 
Prescription for CY 2025 (third quarter) forward using the PPI for 
Pharmaceuticals for Human Use, Prescription for the applicable payment 
year (third quarter). This is the same as the update factor used for 
the OPPS drug packaging threshold, where we originally used the four-
quarter moving average PPI levels for Pharmaceutical Preparations, 
Prescription (BLS series code WPUSI07003, formerly BLS series code 
32541DRX) to trend the $50 threshold forward from the third quarter of 
CY 2005 (when the Pub. L. 108-173 mandated threshold became effective) 
to the third quarter of the applicable payment year (71 FR 68085 and 
68086).
    Therefore, for CY 2026, we propose to update the CY 2025 $630 
threshold amount by the four-quarter moving average PPI levels for 
Pharmaceuticals for Human Use, Prescription to trend the $630 threshold 
forward. Specifically, we propose to use the most recently available 
forecast of the four-quarter moving average PPI levels for 
Pharmaceutical for Human Use, Prescription from the third quarter of 
2025 to the third-quarter of 2026, and to round the resulting dollar 
amount to the nearest $5 increment. Based on this methodology, we 
trended the $630 threshold forward and rounded the resulting dollar 
amount ($654.23) to the nearest $5 increment, which yields a proposed 
figure of $655 per day for CY 2026. Consistent with our methodology and 
practices listed in section V.B.1.b. of this proposed rule, we also 
propose that if more recent data are subsequently available (for 
example, a more recent estimate of the PPI for Pharmaceuticals for 
Human Use, Prescription), we would use such data, if appropriate, to 
determine the CY 2026 diagnostic radiopharmaceutical packaging 
threshold in the final rule.
(3) Amount of Separate Payment for Diagnostic Radiopharmaceuticals 
Exceeding the Threshold
    As discussed in the CY 2025 OPPS/ASC final rule with comment period 
(89 FR 93955 through 93959), once we determine that the per day cost of 
a nonpass-through diagnostic radiopharmaceutical exceeds the cost 
threshold, proposed to be $655 per day for CY 2026, we will then assign 
that radiopharmaceutical to an APC, making it a specified covered 
outpatient drug (SCOD) per section 1833(t)(14)(B) of the Act. We 
propose to continue our current policy for CY 2026, and propose to pay 
for those nonpass-through, separately payable diagnostic 
radiopharmaceuticals based on our authority under section 
1833(t)(14)(A)(iii)(II) of the Act. While, under this authority, we 
would ordinarily use the ASP methodology under section 1847A of the 
Act, we continue to find that the ASP data we have is not usable for 
payment purposes. We continue to believe that arithmetic Mean Unit Cost 
(MUC) would be an appropriate proxy for the average price for a 
diagnostic radiopharmaceutical for a given year, as it is calculated 
based on the average costs for a particular year and is directly 
reflective of the actual cost data that hospitals submit to CMS. 
Therefore, we propose to continue our current policy and propose for CY 
2026 to pay qualifying diagnostic radiopharmaceuticals with per day 
costs above the diagnostic radiopharmaceutical packaging threshold, 
based on their arithmetic MUC, which would be derived from calendar 
year 2024 claims data.
    Although we propose to base payment for qualifying 
radiopharmaceuticals on their arithmetic MUC for CY 2026, we continue 
to encourage manufacturers to submit ASP information for diagnostic 
radiopharmaceuticals, if possible. While we propose to continue to use 
MUC to pay for separately payable diagnostic radiopharmaceuticals in CY 
2026, manufacturers can begin, or continue, to report ASP data for 
potential future use in paying for diagnostic radiopharmaceuticals. For 
CY 2026, ASP reporting is voluntary for diagnostic radiopharmaceuticals 
paid under the OPPS. We encourage interested parties to submit comments 
regarding potential issues that may arise that prevent appropriate ASP 
reporting for diagnostic radiopharmaceuticals. We refer readers to the 
CY 2025 OPPS/ASC final rule with comment period as it discusses some of 
the known concerns regarding ASP reporting for diagnostic 
radiopharmaceuticals (89 FR 93948 through 93963). We reiterate our 
stance from the CY 2025 OPPS/ASC final rule with comment period, that 
if we were to use average sales price as the basis of calculating a 
payment, we believe there must be more consistent, validated, and 
universal reporting in order for ASP to

[[Page 33505]]

be a viable payment methodology (89 FR 93961).
    We also reiterate, as we stated in the CY 2025 OPPS/ASC final rule 
with comment period (89 FR 93957), that there could be potential value 
in the use of ASP data for payment purposes for diagnostic 
radiopharmaceuticals when reported correctly and by all manufacturers 
who manufacture a product that is described by a given HCPCS code. We 
continue to believe that the use of ASP information for OPPS payment 
could provide an opportunity to improve payment accuracy for separately 
payable diagnostic radiopharmaceuticals by applying an established 
methodology that has already been successfully implemented under the 
OPPS for other separately payable drugs and biologicals, as well as 
therapeutic radiopharmaceuticals.
    In order to facilitate potential future payment for diagnostic 
radiopharmaceuticals on ASP, we are seeking comment from interested 
parties on how CMS can ensure more consistent, validated, and universal 
reporting in order for ASP to be a viable payment methodology utilized 
in future rulemaking. For example, we are seeking comment on how CMS 
may update its past guidance, Submission of OPPS ASP Data for Nonpass-
Through Separately Payable Therapeutic Radiopharmaceuticals and 
Radiopharmaceuticals with Pass-Through Status,\6\ in order to reflect 
current clinical practices and to reflect ASP reporting for diagnostic 
radiopharmaceuticals.
---------------------------------------------------------------------------

    \6\ <a href="https://www.cms.gov/medicare/medicare-fee-for-service-payment/hospitaloutpatientpps/downloads/opps_asp_radiopharm_guidance10302009.pdf">https://www.cms.gov/medicare/medicare-fee-for-service-payment/hospitaloutpatientpps/downloads/opps_asp_radiopharm_guidance10302009.pdf</a>.
---------------------------------------------------------------------------

    Additionally, as discussed in section V.B.5. of this proposed rule 
(Proposed Payment for Nonpass-Through Drugs, Biologicals, and 
Radiopharmaceuticals with HCPCS Codes but Without OPPS Hospital Claims 
Data), we propose to set the payment rate for new diagnostic 
radiopharmaceuticals that exceed the diagnostic radiopharmaceutical 
packaging threshold and with HCPCS codes, but which do not have pass-
through status and are without claims data at ASP plus 6 percent. If 
ASP data for these diagnostic radiopharmaceuticals are not available, 
we propose to pay WAC plus 3 percent during the product's initial sales 
period, consistent with our policy described in section V.B.2. of this 
proposed rule. If the WAC also is unavailable, we propose to make 
payment for new diagnostic radiopharmaceuticals at 95 percent of the 
products' most recent AWP. Following the initial sales period, a 
payment rate of WAC plus 6 percent would apply, if ASP data for these 
diagnostic radiopharmaceuticals remain unavailable. We believe the 
volume of products in this category will typically be very low; 
however, in these rare situations, we believe it would continue to be 
appropriate to use ASP, WAC plus 3 or 6 percent, or 95 percent of AWP 
until a MUC is available. As stated in the CY 2025 OPPS/ASC final rule 
with comment period, we stated we believe it would be appropriate to 
use this payment hierarchy until a MUC is available. There is typically 
only one manufacturer for a diagnostic radiopharmaceutical that is new 
and described by a HCPCS code, but without claims data, so CMS does not 
have to ensure all manufacturers are reporting ASP for that particular 
HCPCS code prior to establishing a separate payment amount based on 
ASP. Additionally, although reporting of ASP is not a condition of CMS 
approving a HCPCS application, CMS has the opportunity to actively 
engage with the manufacturer, or sponsor of a HCPCS application, during 
the HCPCS application process. This allows for ongoing dialogue and 
education regarding the unique ASP reporting requirements that may be 
associated with a particular product, including how to ensure the 
reported ASP aligns with the dose descriptor for the newly assigned 
HCPCS code (89 FR 93958). We believe the hierarchy previously specified 
is appropriate to determine the payment for a diagnostic 
radiopharmaceutical that is new and described by a HCPCS code, but 
without claims data, as it is consistent with the typical hierarchy 
associated with payment for drugs and biologicals paid under the OPPS 
as discussed in section V.A. and V.B. of this proposed rule.
(4) Qualifying Diagnostic Radiopharmaceuticals Above the Diagnostic 
Radiopharmaceutical Packaging Threshold
    The HCPCS codes that describe diagnostic radiopharmaceuticals with 
per day costs that exceed the proposed diagnostic radiopharmaceutical 
packaging threshold are proposed to be assigned to a status indicator 
of ``K'', indicating separate payment to be paid based on that HCPCS 
code's arithmetic MUC. A proposed APC and a proposed payment rate would 
be assigned as shown in Addendum B to this proposed rule. HCPCS codes 
that describe diagnostic radiopharmaceuticals with per day costs that 
are at or below the proposed diagnostic radiopharmaceutical packaging 
threshold are proposed to continue to be assigned to a status indicator 
of ``N'', indicating packaged payment.
    The proposed list of diagnostic radiopharmaceuticals that we 
calculated as having per day costs that exceed $655 and their proposed 
status indicators can be found in Table 4.

4. Proposed Implementation of Section 4135 of the Consolidated 
Appropriations Act (CAA), 2023
    The Consolidated Appropriations Act (CAA), 2023 (Pub. L. 117-328), 
was signed into law on December 29, 2022. Section 4135(a) and (b) of 
the CAA, 2023, titled Access to Non-Opioid Treatments for Pain Relief, 
amended sections 1833(t)(16) and 1833(i) of the Act, respectively, to 
provide for temporary additional payments for non-opioid treatments for 
pain relief (as that term is defined in section 1833(t)(16)(G)(i) of 
the Act). In particular, section 1833(t)(16)(G) of the Act provides 
that with respect to a non-opioid treatment for pain relief furnished 
on or after January 1, 2025, and before January 1, 2028, the Secretary 
shall not package payment for the non-opioid treatment for pain relief 
into payment for a covered OPD service (or group of services) and shall 
make an additional payment for the non-opioid treatment for pain relief 
as specified in clause (ii) of that section. Clauses (ii) and (iii) of 
section 1833(t)(16)(G) of the Act provide for the amount of additional 
payment and set a limitation on that amount, respectively.
    The required additional payments began on January 1, 2025, based on 
the policy finalized in the CY 2025 OPPS/ASC final rule with comment 
period (89 FR 94343 through 94361). In section XIII.F. of this proposed 
rule, we propose to continue for CY 2026 the policy finalized in the CY 
2025 OPPS/ASC final rule with comment period. We also propose non-
opioid treatments for pain relief that would qualify under this policy 
for CY 2026 and seek public comment on those product evaluations.
5. Calculation of OPPS Scaled Payment Weights
    We established a policy in the CY 2013 OPPS/ASC final rule with 
comment period (77 FR 68283) of using geometric mean-based APC costs to 
calculate relative payment weights under the OPPS. In the CY 2025 OPPS/
ASC final rule with comment period (89 FR 93964 through 93965), we 
applied this policy and calculated the relative

[[Page 33507]]

payment weights for each APC for CY 2025 that were shown in Addenda A 
and B of the CY 2025 OPPS/ASC final rule with comment period (which 
were made available via the internet on the CMS website) using the APC 
costs discussed in sections II.A.1. and II.A.2. of the CY 2025 OPPS/ASC 
final rule with comment period (89 FR 93921 through 93947). For CY 
2026, as we did for CY 2025, we propose to continue to apply the policy 
established in CY 2013 and calculate relative payment weights for each 
APC for CY 2026 using geometric mean-based APC costs.
    For CY 2012 and CY 2013, outpatient clinic visits were assigned to 
one of five levels of clinic visit APCs, with APC 0606 representing a 
mid-level clinic visit. In the CY 2014 OPPS/ASC final rule with comment 
period (78 FR 75036 through 75043), we finalized a policy that created 
alphanumeric HCPCS code G0463 (Hospital outpatient clinic visit for 
assessment and management of a patient), representing all clinic visits 
under the OPPS. HCPCS code G0463 was assigned to APC 0634 (Hospital 
Clinic Visits). We also finalized a policy to use CY 2012 claims data 
to develop the CY 2014 OPPS payment rates for HCPCS code G0463 based on 
the total geometric mean cost of the levels one through five CPT 
Evaluation or Assessment and Management (E/M) codes for clinic visits 
previously recognized under the OPPS (CPT codes 99201 through 99205 and 
99211 through 99215). In addition, we finalized a policy to no longer 
recognize a distinction between new and established patient clinic 
visits.
    For CY 2016, we deleted APC 0634 and reassigned the outpatient 
clinic visit HCPCS code G0463 to APC 5012 (Level 2 Examinations and 
Related Services) (80 FR 70372). For CY 2026, as we did for CY 2025, we 
propose to continue to standardize all the relative payment weights to 
APC 5012. We believe that standardizing relative payment weights to the 
geometric mean of the APC to which HCPCS code G0463 is assigned 
maintains consistency in calculating unscaled weights that represent 
the cost of some of the most frequently provided OPPS services. For CY 
2026, as we did for CY 2025, we propose to assign APC 5012 a relative 
payment weight of 1.00 and to divide the geometric mean cost of each 
APC by the geometric mean cost for APC 5012 to derive the unscaled 
relative payment weight for each APC. The choice of the APC on which to 
standardize the relative payment weights does not affect payments made 
under the OPPS because we scale the weights for budget neutrality.
    Section 1833(t)(9)(B) of the Act requires that APC reclassification 
and recalibration changes, wage index changes, and other adjustments be 
made in a budget neutral manner. Budget neutrality ensures that the 
estimated aggregate weight under the OPPS for CY 2026 is neither 
greater than nor less than the estimated aggregate weight that would 
have been calculated without the changes. To comply with this 
requirement concerning the APC changes, we propose to compare the 
estimated aggregate weight using the CY 2025 scaled relative payment 
weights to the estimated aggregate weight using the proposed CY 2026 
unscaled relative payment weights.
    For CY 2025, we multiplied the CY 2025 scaled APC relative payment 
weight applicable to a service paid under the OPPS by the volume of 
that service from CY 2024 claims to calculate the total relative 
payment weight for each service. We then added together the total 
relative payment weight for each of these services to calculate an 
estimated aggregate weight for the year. For CY 2026, we propose to 
apply the same process using the estimated CY 2026 unscaled relative 
payment weights rather than scaled relative payment weights. We propose 
to calculate the weight scalar by dividing the CY 2025 estimated 
aggregate weight by the unscaled CY 2026 estimated aggregate weight.
    For a detailed discussion of the weight scalar calculation, we 
refer readers to the OPPS claims accounting document available on the 
CMS website at <a href="https://www.cms.gov/medicare/payment/prospective-payment-systems/hospital-outpatient/regulations-notices">https://www.cms.gov/medicare/payment/prospective-payment-systems/hospital-outpatient/regulations-notices</a>. Click on the 
link labeled ``Hospital Outpatient Prospective Payment System Proposed 
Rule'' for 2026, which can be found under the heading ``Hospital 
Outpatient Regulations and Notices'' and open the claims accounting 
document link, which is labeled ``2026 Proposed Rule OPPS Claims 
Accounting (PDF).''
    We propose to compare the estimated unscaled relative payment 
weights in CY 2026 to the estimated total relative payment weights in 
CY 2025 using CY 2024 claims data, holding all other components of the 
payment system constant to isolate changes in total weight. Based on 
this comparison, we propose to adjust the calculated CY 2026 unscaled 
relative payment weights for purposes of budget neutrality. We propose 
to adjust the estimated CY 2026 unscaled relative payment weights by 
multiplying them by a proposed weight scalar of 1.4624 to ensure that 
the proposed CY 2026 relative payment weights are scaled to be budget 
neutral. The proposed CY 2026 relative payment weights listed in 
Addenda A and B to this proposed rule (which are available via the 
internet on the CMS website at <a href="https://www.cms.gov/medicare/payment/prospective-payment-systems/hospital-outpatient/regulations-notices">https://www.cms.gov/medicare/payment/prospective-payment-systems/hospital-outpatient/regulations-notices</a>) 
are scaled and incorporate the recalibration adjustments discussed in 
sections II.A.1. and II.A.2. of this proposed rule.
    Section 1833(t)(14) of the Act provides the methodology for payment 
rates for certain specified covered outpatient drugs (SCODs). Section 
1833(t)(14)(H) of the Act provides that additional expenditures 
resulting from this paragraph shall not be taken into account in 
establishing the conversion factor, weighting, and other adjustment 
factors for 2004 and 2005 under paragraph (9) but shall be taken into 
account for subsequent years. Therefore, the cost of those SCODs (as 
discussed in section V.B.2. of this proposed rule) is included in the 
budget neutrality calculations for the CY 2026 OPPS.

B. Proposed Conversion Factor Update

1. OPD Fee Schedule Increase Factor
    Section 1833(t)(3)(C)(ii) of the Act requires the Secretary to 
update the conversion factor used to determine the payment rates under 
the OPPS on an annual basis by applying the OPD fee schedule increase 
factor. For purposes of section 1833(t)(3)(C)(iv) of the Act, subject 
to sections 1833(t)(17) and 1833(t)(3)(F) of the Act, the OPD fee 
schedule increase factor is equal to the hospital inpatient market 
basket percentage increase applicable to hospital discharges of the Act 
(or an amount that is computed and applied with respect to covered OPD 
services). In the FY 2026 IPPS/Long Term Care Hospital (LTCH) PPS 
proposed rule (90 FR 18266), consistent with current law, based on IHS 
Global, Inc.'s fourth quarter 2024 forecast, the proposed FY 2026 IPPS 
market basket percentage increase was 3.2 percent. We note that under 
our regular process for the CY 2026 OPPS/ASC final rule with comment 
period, we would use the market basket update for the FY 2026 IPPS/LTCH 
PPS final rule. If that forecast is different than the IPPS market 
basket percentage increase used for this proposed rule, the CY 2026 
OPPS/ASC final rule with comment period OPD fee schedule increase 
factor would reflect that updated forecast of the market basket 
percentage increase.
    For CY 2026, we propose to use the estimate of the hospital 
inpatient market basket percentage increase of 3.2

[[Page 33508]]

percent as one component to calculate the OPD fee schedule increase 
factor.
2. Productivity Adjustment
    Section 1833(t)(3)(F)(i) of the Act requires that, for 2012 and 
subsequent years, the OPD fee schedule increase factor under 
subparagraph (C)(iv) be reduced by the productivity adjustment 
described in section 1886(b)(3)(B)(xi)(II) of the Act. Section 
1886(b)(3)(B)(xi)(II) of the Act defines the productivity adjustment as 
equal to the 10-year moving average of changes in annual economy-wide, 
private nonfarm business multifactor productivity (MFP) (as projected 
by the Secretary for the 10-year period ending with the applicable 
fiscal year, year, cost reporting period, or other annual period) (the 
``productivity adjustment''). In the FY 2012 IPPS/LTCH PPS final rule 
(76 FR 51689 through 51692), we finalized our methodology for 
calculating and applying the productivity adjustment. The U.S. 
Department of Labor's Bureau of Labor Statistics (BLS) publishes the 
official measures of private nonfarm business productivity for the U.S. 
economy. We note that previously the productivity measure referenced in 
section 1886(b)(3)(B)(xi)(II) of the Act was published by BLS as 
private nonfarm business multifactor productivity. Beginning with the 
November 18, 2021, release of productivity data, BLS replaced the term 
multifactor productivity (MFP) with total factor productivity (TFP). 
BLS noted that this is a change in terminology only and will not affect 
the data or methodology. As a result of the BLS name change, the 
productivity measure referenced in section 1886(b)(3)(B)(xi)(II) of the 
Act is now published by BLS as private nonfarm business total factor 
productivity. However, as mentioned, the data and methods are 
unchanged. Please see <a href="http://www.bls.gov">www.bls.gov</a> for the BLS historical published TFP 
data. A complete description of IHS Global, Inc.'s (IGI) TFP projection 
methodology is available on the CMS website at <a href="https://www.cms.gov/data-research/statistics-trends-and-reports/medicare-program-rates-statistics/market-basket-research-and-information">https://www.cms.gov/data-research/statistics-trends-and-reports/medicare-program-rates-statistics/market-basket-research-and-information</a>. In addition, we note 
that beginning with the FY 2022 IPPS/LTCH PPS final rule, we refer to 
this adjustment as the productivity adjustment rather than the MFP 
adjustment to more closely track the statutory language in section 
1886(b)(3)(B)(xi)(II) of the Act. We note that the adjustment continues 
to rely on the same underlying data and methodology. In the FY 2026 
IPPS/LTCH PPS proposed rule (90 FR 18266), the proposed productivity 
adjustment for FY 2026 was 0.8 percentage point.
    Therefore, we propose that the productivity adjustment for the CY 
2026 OPPS/ASC would be 0.8 percentage point. We also propose that if 
more recent data subsequently become available after the publication of 
the CY 2026 OPPS/ASC proposed rule (for example, a more recent estimate 
of the market basket percentage increase and/or the productivity 
adjustment), we would use such data, if appropriate, to determine the 
CY 2026 hospital inpatient market basket update and the productivity 
adjustment for the final rule, which are components in calculating the 
OPD fee schedule increase factor under sections 1833(t)(3)(C)(iv) and 
1833(t)(3)(F) of the Act.
    We note that section 1833(t)(3)(F) of the Act provides that 
application of this subparagraph may result in the OPD fee schedule 
increase factor under section 1833(t)(3)(C)(iv) of the Act being less 
than 0.0 percent for a year and may result in OPPS payment rates being 
less than rates for the preceding year. As described in further detail 
below, we proposed for CY 2026 an OPD fee schedule increase factor of 
2.4 percent for the CY 2026 OPPS/ASC (which is the proposed estimate of 
the hospital inpatient market basket percentage increase of 3.2 
percent, less the proposed 0.8 percentage point productivity 
adjustment).
3. Other Conversion Factor Adjustments
    To set the OPPS conversion factor for 2026, we propose to increase 
the CY 2025 conversion factor of $89.169 by 2.4 percent. In accordance 
with section 1833(t)(9)(B) of the Act, we propose to further adjust the 
conversion factor for CY 2026 to ensure that any revisions made to the 
wage index and rural adjustment are made on a budget neutral basis. We 
propose to apply an overall budget neutrality factor of 1.0116 for wage 
index changes by comparing proposed total estimated payments from our 
simulation model using the proposed FY 2026 IPPS wage indexes to those 
payments using the CY 2025 OPPS wage indexes. We further propose to 
calculate an additional budget neutrality factor of 0.9955 to account 
for our proposed policy to cap wage index reductions for hospitals at 5 
percent on an annual basis and the CY 2026 proposed transitional 
exception.
    For CY 2026, we propose to maintain the current rural adjustment 
policy, as discussed in section II.E. of this proposed rule with 
comment period. Therefore, the proposed budget neutrality factor for 
the rural adjustment is 1.0000.
    We propose to calculate a CY 2026 budget neutrality adjustment 
factor for the cancer hospital payment adjustment. We previously 
finalized transitioning from the target PCR of 0.89 for CYs 2020 
through 2023 (which included the 1.0 percentage point reduction as 
required by section 16002(b) of the 21st Century Cures Act) and 
incrementally reducing the target PCR by an additional 1.0 percentage 
point for each calendar year, beginning with CY 2024, until the target 
PCR equals the PCR of non-cancer hospitals calculated using the most 
recent data minus 1.0 percentage point as required by section 16002(b) 
of the 21st Century Cures Act. Based on the most recent data available 
for this proposed rule, the target PCR now equals the PCR of non-cancer 
hospitals. We propose a CY 2026 target PCR equal to 0.87 for the cancer 
hospital payment adjustment, which includes the 1.0 percentage point 
reduction as required by section 16002(b) of the 21st Century Cures 
Act. We note that this proposed target PCR is the same as the final 
target PCR established in the CY 2025 OPPS (89 FR 93979). Therefore, we 
propose to apply a budget neutrality adjustment factor of 1.0000 to the 
conversion factor for the cancer hospital payment adjustment.
    For the CY 2026 OPPS/ASC proposed rule, we estimate that proposed 
pass-through spending for drugs, biologicals, and devices for CY 2026 
will equal approximately $587 million, which represents 0.59 percent of 
total projected CY 2026 OPPS spending. Therefore, we state that the 
proposed conversion factor would be adjusted by the difference between 
the 0.37 percent estimate of pass-through spending for CY 2025 and the 
0.59 percent estimate of proposed pass-through spending for CY 2026, 
resulting in a proposed decrease to the conversion factor for CY 2026 
of 0.22 percentage point.
    We propose that estimated payments for outliers would be 1.0 
percent of total OPPS payments for CY 2026. We estimate for the 
proposed rule that outlier payments will be approximately 0.92 percent 
of total OPPS payments in CY 2025; the 1.00 percent for proposed 
outlier payments in CY 2026 would constitute a 0.08 percentage point 
increase in payment in CY 2026 relative to CY 2025.
    For CY 2026, we propose to use a conversion factor of $91.747 in 
the calculation of the national unadjusted payment rates for those 
items and services for which payment rates are calculated using 
geometric mean costs; that is, the proposed OPD fee schedule

increase factor of 1.024 (2.4 percent for CY 2026), the required 
proposed wage index budget neutrality adjustment of approximately 
1.0116, the proposed 5 percent annual cap for individual hospital wage 
index reductions adjustment and the proposed transitional exception of 
approximately 0.9955, the proposed cancer hospital payment adjustment 
of 1.0000, and the proposed adjustment factor of 0.9978 (a decrease of 
0.22 percentage point) for the difference in pass-through spending, and 
a 0.08 percentage point increase in projected OPPS spending for the 
projected increase in outlier payments, which resulted in a proposed 
conversion factor for CY 2026 of $91.747
    For CY 2026, we also propose that hospitals that fail to meet the 
reporting requirements of the Hospital OQR Program would continue to be 
subject to a further reduction of 2.0 percentage points to the OPD fee 
schedule increase factor. For hospitals that fail to meet the 
requirements of the Hospital OQR Program, we propose to make all other 
adjustments discussed above and apply an adjustment factor of 0.9805 to 
the proposed CY 2026 conversion factor of $91.747. We propose that the 
hospitals that fail to meet the requirements of the Hospital OQR 
Program will use a reduced OPD fee schedule update factor of 0.4 
percent (that is, the proposed OPD fee schedule increase factor of 2.4 
percent further reduced by 2.0 percentage points).
    For CY 2026, as previously discussed in section V.B.7. of this 
proposed rule, we propose to reduce payments for non-drug items and 
services for hospitals for whom the annual reduction to payment amounts 
under Sec.  419.32(b)(1)(iv)(B)(12) applies with a 2 percentage point 
reduction to the OPD fee schedule increase factor, explained in more 
detail in section XIV.D. of this proposed rule. This would result in a 
proposed reduced conversion factor for CY 2026 of approximately $89.958 
for this group of hospitals. The calculations we performed to determine 
the CY 2026 proposed conversion factor are shown in Table 5.

C. Proposed Wage Index Changes

    Section 1833(t)(2)(D) of the Act requires the Secretary to 
determine a wage adjustment factor to adjust the portion of payment and 
coinsurance attributable to labor-related costs for relative 
differences in labor and labor-related costs across geographic regions 
in a budget neutral manner (codified at 42 CFR 419.43(a)). This portion 
of the OPPS payment rate is called the OPPS labor-related share. Budget 
neutrality is discussed in section II.A.5. of this proposed rule.
    The OPPS labor-related share is 60 percent of the national OPPS 
payment. This labor-related share is based on a regression analysis 
that determined that, for all hospitals, approximately 60 percent of 
the costs of services paid under the OPPS were attributable to wage 
costs. We confirmed that this labor-related share for outpatient 
services is appropriate during our regression analysis for the payment 
adjustment for rural hospitals in the CY 2006 OPPS final rule with 
comment period (70 FR 68553). We propose to continue this policy for 
the CY 2026 OPPS/ASC. We refer readers to section II.C. of this 
proposed rule for a description and an example of how the wage index 
for a particular hospital is used to determine payment for the 
hospital.
    As discussed in the claims accounting narrative included with the 
supporting documentation for this proposed rule (which is available via 
the internet on the CMS website (<a href="https://www.cms.gov/medicare/payment/prospective-payment-systems/hospital-outpatient/regulations-notices">https://www.cms.gov/medicare/payment/prospective-payment-systems/hospital-outpatient/regulations-notices</a>)), 
for estimating APC costs, we would standardize 60 percent of estimated 
claims costs for geographic area wage variation using the same FY 2026 
pre-reclassified wage index that we use under the IPPS to standardize 
costs. This standardization process removes the effects of differences 
in area wage levels from the determination of a national unadjusted 
OPPS payment rate and copayment amount.
    Under Sec. Sec.  419.41(c)(1) and 419.43(c) (published in the OPPS 
April 7, 2000, final rule with comment period (65 FR 18495 and 18545)), 
the OPPS ado
