CY 2027 MPFS Advocacy Stance Report

01 How the evidence is classified

The strongest available firsthand source controls each stance. No position is inferred from silence.

Class	Meaning	How used
Class 1	Formal signed comment letter or docket submission	Controls the organization's formal recommendation on the covered topic.
Class 2	Official organization statement or press release	Establishes an official high-level position.
Class 3	Official organization analysis, webinar, slides, or transcript	Establishes emphasis and attributed analysis; may precede the final comment letter.
Gap	No public firsthand CY 2027 response located	No stance is inferred from silence or prior-year material.

02 Priority view: multispecialty physician group

Rank reflects financial, operational, clinical, and implementation relevance, not the number of organizations that agree.

Rank	Topic	Organizations emphasizing	Firsthand position summary	Multispecialty relevance
1	Medicare physician payment and MEI-linked reform	AMGA, AMA, AAFP, TMA, ACP, MGMA, ACS	Broad agreement that annual statutory updates and temporary patches are inadequate; durable inflation-linked reform is favored.	Budget planning and recruitment risk across every specialty.
2	Modifier 25 same-day E/M and global procedure reduction	AMA, AAFP, AAP, ACOG, ACP, ACS, MGMA, TMA; AMGA	Formal coalition opposition to the 50% reduction; AMGA also identified it as a top member concern.	Highest immediate risk for office-based procedural specialties.
3	Practice expense methodology and specialty redistribution	AMGA, AMA, MGMA, ACS	Concern about broad redistribution and implementation without adequate specialty-specific validation.	Requires CPT, site-of-service, and specialty modeling.
4	RPM and RTM staffing, initiating visit, and valuation	AMGA, AMA, MGMA, ACP	Operational concern, especially direct-employment-only clinical staff and payment/coding changes.	Could invalidate outsourced workflows and alter program economics.
5	G2211 replacement with MOD1 and MOD2	AMGA, NAACOS, AAFP, ACP, AMA	Generally viewed as a major longitudinal-care payment change; support is strongest for accountable/primary care, with implementation and redistribution concerns.	Potential primary care revenue opportunity and ACO cost/assignment change.
6	MIPS sunset, MVPs, core measures, PI, and ePA	AMA, AMGA, TMA, MGMA, NAACOS	Support for burden relief is mixed with concern about a mandatory MVP transition and readiness for new reporting requirements.	Requires group-wide reporting strategy before 2029 and ePA readiness for 2028.
7	QP status at the TIN/NPI and Advanced APM thresholds	AMGA, AMA, NAACOS	Concern that limiting benefits to participating TIN/NPI combinations fragments clinician obligations and weakens entity-level participation.	Multi-TIN physicians may be QPs at the physician group but MIPS-subject elsewhere.
8	MSSP benchmark methodology, ACPT, Level E, and ENHANCED	NAACOS, AMGA, AMA, MGMA	NAACOS supports Level E 60% and prior-savings/ACPT protections, but opposes or questions the ENHANCED regional reduction and the 5% cap.	Affects ACO financial modeling and track-selection analysis.
9	MSSP quality, APP Plus, Medicare eCQMs, and CEHRT	NAACOS, AMGA, AMA, MGMA	NAACOS calls the quality package a major win; stakeholders favor transition flexibility and lower reporting burden.	Could reduce burden, but only if EHR and registry workflows are reliable and auditable.
10	Ambulatory Specialty Model	AMGA, ACS, AMA, MGMA	AMGA continues to oppose mandatory, duplicative specialist accountability and seeks voluntary, aligned design.	Recruiting, compensation, and all-Part-B payment exposure for selected specialists.
11	Assignment and beneficiary eligibility	NAACOS, AMGA, AMA	Potential to reduce attribution leakage and expand assignment, with concern about higher-cost added beneficiaries and uneven ACO effects.	Could improve retention but change population risk.
12	Maternity coding transition	ACOG, AMA, MGMA	ACOG supports the new CPT structure and opposes parallel legacy Medicare G-codes; operational preparation is still required.	OB/GYN coding, payer-contract, and workflow transition.

03 Priority view: VBC and MSSP ACO

06 CMS agency framing

This records how CMS explains its direction. It is not advocacy and does not replace the proposed rule.

CMS framing	Official examples	How to use it
Prevention, wellness, burden reduction, and meaningful participation	QPP proposals, core measures, MVPs, quality-reporting changes.	Useful for understanding stated priorities; verify mechanics in the rule.
Strengthen accountable-care incentives and participation	Level E 60%, benchmark changes, growth adjustment, MOD2, assignment, and beneficiary policies.	Signals strategy; does not prove a favorable financial result for any particular organization.
Address overlap, billing accuracy, and program integrity	Modifier 25/global reduction, RPM/RTM staffing, global package, duplicate testing.	Explains rationale; does not establish the magnitude of actual overlap.
Move toward digital quality reporting	Medicare eCQMs, CEHRT alternatives, and FHIR RFI.	Future direction remains subject to readiness and later rulemaking.

Stakeholders broadly agree that the physician-payment baseline is unstable and that the proposed modifier-25 cut is harmful. The sharpest ACO disagreement is not over whether MSSP gains tools, but whether the ENHANCED regional reduction and remaining benchmark caps weaken the high-performing ACOs CMS wants to retain.
