CMS released performance year 2024 results for the Medicare Shared Savings Program (MSSP). Key findings:
Financial performance:
- Net Medicare savings: $2.48 billion — record, 8th consecutive year of net savings
- Gross savings (before shared savings payments): $6.6 billion total
- 75% of ACOs earned shared savings, receiving $4.1 billion in performance payments
- Per capita net savings: $241 (up $34 from 2023)
- Per capita gross savings: $643 (up $128 from 2023)
Risk track distribution:
- Two-thirds of ACOs participating in Level E or Enhanced (downside risk) tracks
- ACOs in Level E and Enhanced generated more than two-thirds of all savings ($5.4B of $6.6B gross)
Quality metrics:
- Nearly every ACO met CMS quality standards — continuing a decade-long trend
- ACOs outperformed non-ACO physician groups on:
- Screening for Depression and Follow-up Plan: 53.53% (ACO) vs 44.42% (non-ACO)
- Controlling High Blood Pressure: 71.21% vs 67.82%
- Improved performance on A1c control, cancer screening
Enrollment context:
- Total MSSP ACO enrollment growing year-over-year
- CMS 2026 rule making two-sided risk the default: new Ambulatory Specialty Model (ASM) for heart failure and low back pain, restricting one-sided MSSP participation
Agent Notes
Why this matters: This is the empirical proof that value-based care's structural fix thesis (Belief 3) actually works at scale. $2.48B in net annual savings is not aspirational — it's measured, audited, and eighth-year consecutive. This is the strongest single piece of evidence in the KB that VBC is more than policy proposal.
What surprised me: The quality improvement alongside cost reduction. The classic critique of VBC is that it will cut costs by under-treating patients. The ACO data shows the opposite — ACOs outperform peers on depression screening, BP control, cancer screening WHILE generating $2.48B in savings. Cost and quality are moving together.
What I expected but didn't find: Any evidence of MSSP performance deteriorating. Given the MA disruptions (CMS tightening, UHG losses, Humana exits), I expected MSSP to show similar stress. Instead it's accelerating.
KB connections:
- Directly confirms value-based care transitions stall at the payment boundary because 60 percent of payments touch value metrics but only 14 percent bear full risk — this is the state of the TRANSITION, not proof VBC doesn't work
- Directly supports Belief 3: "Value-based care is the structural fix, but transition is slow"
- Connects to the healthcare attractor state is a prevention-first system where aligned payment continuous monitoring and AI-augmented care delivery create a flywheel that profits from health rather than sickness
Extraction hints:
- PRIMARY: "MSSP ACOs generated record $2.48B in net Medicare savings in 2024 for the eighth consecutive year, while maintaining superior quality performance compared to non-ACO peers — empirically confirming that cost and quality improvement are achievable simultaneously under value-based payment"
- SECONDARY: Two-thirds of MSSP ACOs now in downside risk tracks — the transition IS advancing despite slow aggregate payment statistics
- The per capita savings growth ($34 more in net, $128 more in gross vs. 2023) shows acceleration, not stagnation
Context: Released September 2025. Most recent publicly available MSSP performance data. CMS simultaneously issued 2026 rules expanding mandatory risk-bearing — the structural direction is accelerating.
Curator Notes
PRIMARY CONNECTION: value-based care transitions stall at the payment boundary because 60 percent of payments touch value metrics but only 14 percent bear full risk WHY ARCHIVED: Belief 3 disconfirmation target — does VBC structural fix actually work? This is the strongest empirical answer: record $2.48B savings, 8th consecutive year, quality improving alongside costs. Disconfirmation FAILS — Belief 3 confirmed. EXTRACTION HINT: Focus on the cost-quality co-improvement (defeats the under-treatment critique) and the acceleration of downside risk adoption (2/3 of ACOs now in downside risk). Two claims, not one.
