Key Takeaways from CMS’s New 2027 Medicare Physician Payment Proposed Rule

On July 14, the Centers for Medicare & Medicaid Services (CMS) released its 1,592-page proposed regulation outlining payment policies and quality programs for Medicare under the Physician Fee Schedule (PFS) for calendar year (CY) 2027. CMS released the proposed rule via a press release titled: “CMS Proposes Transformational Medicare Reforms to Expand Accountable Care, Modernize Physician Payment, and Shift from Sick Care to Healthcare.” Every year, healthcare leaders, practice administrators, and clinicians closely analyze this release because it updates the foundational rules governing Medicare’s value-based care programs and traditional fee-for-service payment systems.   2027 CMS Proposed Rule: Key Facts at a Glance

• Proposed Qualifying Advanced APM Conversion Factor: $33.17 (-1.2% / -$0.40 from 2026)
• Proposed Non-Qualifying APM Conversion Factor: $32.84 (-1.7% / -$0.56 from 2026)
• Mandatory MIPS Value Pathways (MVPs) Transition: Proposed to begin in performance year 2029
• Total MVPs for 2027: 30 available tracks (27 existing revised + 3 new proposed)
• MSSP ACO Shared Savings Rate: Proposed increase from 50% to 60% for Basic Track Level E
• Public Comment Deadline: September 14, 2026
• Expected Final Rule & Implementation Date: Final rule expected in late October/early November 2026; implementation on January 1, 2027

  Proposed 2027 Medicare Conversion Factor Decreases As mandated by the Medicare Access and CHIP Reauthorization Act of 2015 (MACRA), CMS applies two separate conversion factors for the Medicare Physician Fee Schedule: one for qualifying advanced Alternative Payment Model (APM) participants (QPs) and one for non-qualifying clinicians. The baseline statutory annual update for the qualifying APM conversion factor is +0.75%, while the baseline update for the non-qualifying factor is +0.25%. However, following the expiration of the temporary 2.5% statutory payment increase provided for 2026 under the One Big Beautiful Bill Act, CMS proposes baseline rate reductions across both tracks for 2027. CY 2026 vs. Proposed CY 2027 PFS Conversion Factor Comparison

Track / Clinician Category	2026 Conversion Factor	Proposed 2027 Conversion Factor	Net Proposed Change	Percent Change
Qualifying Advanced APM (QP)	$33.57	$33.17	-$0.40	-1.2%
Non-Qualifying APM / Traditional MIPS	$33.40	$32.84	-$0.56	-1.7%

Note: For MIPS-eligible clinicians and medical groups, individual 2027 Medicare Part B payment adjustments will also factor in positive or negative adjustments based on 2025 MIPS performance.   CMS Proposes Mandatory MIPS Value Pathways (MVPs) for 2029 A central provision of the proposed rule is CMS’s timeline to phase out traditional MIPS and make participation in MIPS Value Pathways (MVPs) mandatory for all eligible clinicians starting with the 2029 performance year. The Evolution of the MVP Framework

1. 2019–2022: CMS conceptualizes MVPs to streamline quality reporting and align measures around specific specialties and medical conditions.
2. 2023 (Launch): CMS rolls out the first 12 voluntary MVPs.
3. 2024–2026: Incremental expansions bring the total to 27 voluntary MVPs by 2026.
4. 2027 (Proposed): CMS proposes 3 new MVPs—focusing on diabetic disease, hypertension, and hospitalist care—bringing the total to 30 available pathways, alongside minor updates to the existing 27 tracks.
5. 2029 (Proposed): Traditional MIPS sunsetting; MVP reporting becomes mandatory across all specialties.

Because CMS is directing long-term focus toward the MVP transition, the 2027 proposed rule suggests only minor adjustments to traditional MIPS categories, measures, and scoring thresholds.   Key Reforms to the Medicare Shared Savings Program (MSSP) Following record-setting participation in the Medicare Shared Savings Program (MSSP)—with 511 participating ACOs covering 12.6 million Medicare beneficiaries—CMS proposes targeted enhancements to encourage long-term commitment to accountable care models:

• Increased Shared Savings Rate: CMS proposes increasing the shared savings rate for Basic Track Level E from 50% to 60%, allowing high-performing ACOs to retain a larger share of earned savings.
• Refined Financial Benchmarking: Adjustments to historical cost benchmark calculations designed to make participation more sustainable and attractive for mature, experienced ACOs.
• Quality & EHR Alignment: Continued refinements to digital quality measure reporting and certified electronic health record technology (CEHRT) compliance requirements.

  Additional Payment Updates: Primary Care and Behavioral Health The 1,592-page proposed rule includes several additional policy provisions aimed at expanding specific care delivery areas:

• Enhanced Primary Care Support: Expanded fee-for-service coding and payment incentives designed to support longitudinal relationship-building and advanced primary care coordination.
• Behavioral Health Integration: Broader coverage and reimbursement opportunities for integrated mental and behavioral health services within ambulatory settings.
• Practice Workflow & Compliance Considerations: Refinements across various specialized services that will require ambulatory practices to review documentation workflows, EHR templates, and compliance routines prior to 2027.

  Where the Proposed Rule Fits into the Healthcare Policy Landscape Immediately following CMS’s announcement, major physician trade and medical specialty organizations—including the American Medical Group Association (AMGA) and the American Medical Association (AMA)—called on Congress to intervene before December 31 to avert the proposed payment reductions. Because statutory budget neutrality constraints prevent CMS from unilaterally eliminating the proposed cuts in the final rule, Congressional legislative action is required to prevent payment decreases. In addition, stakeholders will closely watch whether public comments cause CMS to adjust its proposed 2029 timeline for mandatory MVP reporting.   What Medical Practices Should Do Now Ambulatory practices and healthcare organizations should consider the following proactive steps:

1. Model Financial Impacts: Analyze your practice’s Medicare patient volume and service mix against the proposed $33.17 (QP) and $32.84 (non-QP) conversion factors to evaluate potential revenue shifts for CY 2027.
2. Evaluate Your MIPS vs. MVP Strategy: Review available MVP specialties (including the 3 new tracks for diabetes, hypertension, and hospitalist care) and assess your readiness for the proposed mandatory 2029 transition.
3. Review Quality Reporting & EHR Workflows: Ensure your clinical documentation and health IT infrastructure support digital quality metrics and evolving CEHRT standards.
4. Submit Public Comments: Provide formal feedback directly to CMS via gov before the September 14, 2026 comment deadline.
5. Track the Final Rule: Monitor CMS announcements in late October or early November 2026 to confirm finalized policies and payment rates.

  Frequently Asked Questions (FAQ) When will the 2027 Medicare Physician Fee Schedule be finalized? CMS is scheduled to release the final rule with comment period in late October or early November 2026, with all finalized policies taking effect on January 1, 2027. Can CMS stop the proposed Medicare payment cuts on its own? No. Under the statutory budget neutrality rules established by Congress in MACRA, CMS does not have the administrative authority to reverse the baseline cuts. Congressional legislation is required to avert the reductions. When will MIPS Value Pathways (MVPs) become mandatory? Under the CY 2027 proposed rule, CMS proposes to make MVP participation mandatory for all MIPS-eligible clinicians starting in the 2029 performance year.   Official Regulatory Resources & Further Reading
