Inside the Medicare Innovation Center: Shaping the Next Era of Value-Based Care

The Center for Medicare and Medicaid Innovation (CMMI), often referred to as the "Medicare Innovation Center," is the federal government's primary engine for testing new ways to deliver and pay for healthcare. Established by the Affordable Care Act (ACA), it holds a statutory mandate to reduce program expenditures while maintaining or improving the quality of care.

Strategic Shift: The 2030 Goal

A cornerstone of the current CMMI strategy is the goal of having 100% of Traditional Medicare beneficiaries and the vast majority of Medicaid beneficiaries in an "accountable care relationship" by 2030.

Progress as of January 2025:

• 53.4% of people with Traditional Medicare are now in an accountable care relationship.

• This represents 14.8 million people, a significant increase from 12.9 million in 2024.

• The Medicare Shared Savings Program (MSSP) remains the largest driver, with 476 ACOs serving over 11.2 million beneficiaries.

  
  

Spotlight on Health Equity: The ACO REACH Model

While traditional models often struggled with representative enrollment, the ACO REACH (Realizing Equity, Access, and Community Health) model was launched in 2023 specifically to address disparities.

Key Statistics & Impact (2023-2025):

• Financial Adjustments: CMMI introduced the Health Equity Benchmark Adjustment (HEBA). In 2024, the formula was updated to a blend of 50% national and 50% state Area Deprivation Index (ADI) to better capture local needs.

  
  

• Regional Winners/Losers: Under the updated formula, 45% of census block groups in California and 36.1% in New York saw positive financial adjustments (increased funding for equity), while Puerto Rico (74%) and Mississippi (60%) saw higher rates of negative adjustments.

  
  

• Participant Demographics: A 2025 analysis of Year 1 (2023) data showed that despite equity goals, REACH beneficiaries were slightly more likely to be White (80.2%) compared to the overall Medicare FFS population (77.2%). Black enrollment in REACH was 5.9% (vs. 8.2% overall Medicare) and Hispanic enrollment was 5.8% (vs. 6.7% overall).

  
  

• Safety Net Expansion: Despite these demographic challenges, safety net provider participation in CMMI equity initiatives doubled in 2023 and grew an additional 25% in 2024.

  
  

Financial Performance: Mixed Results

The CBO originally projected billions in savings, but CMMI's first decade resulted in a net increase in spending of approximately $5 billion. However, recent models show localized success:

Model Category	Key Performance Metric (Recent Data)
ACO REACH	Achieved $203 in net savings per beneficiary (vs. $173 in MSSP).
High Needs ACOs	Demonstrated a 13.2% net savings rate, significantly higher than Standard ACOs (2.8%).
Maryland All-Payer	Generated $975 million in Medicare savings and reduced mortality by 8.8%.
Home Health VBP	Reduced Medicare expenditures by $949 million and mortality by 37%.

Future Outlook: 2025 and Beyond

In May 2025, CMS announced a strategic "pivot" that emphasizes:

1. Financial Rigor: Prioritizing models with strong downside risk over broad participation.

2. Tech-Enabled Care: Increasing requirements for AI, remote monitoring, and digital health tools.

3. Prevention: "Doubling down" on evidence-based preventive care to reduce long-term federal tax dollar expenditure.

   
   

For organizations like Just Whole Care (JWC), this environment necessitates being "PPS optimized and APM ready," ensuring that clinical workflows for vulnerable populations (like Dyadic Services) are aligned with these federal value-based benchmarks.
