+extraction_notes: "Extracted three new claims about MA risk adjustment mechanics and one enrichment to existing chart review claim. The source provides crucial mechanical detail distinguishing V28 (what gets coded) from chart review exclusion (how it gets coded) as complementary reforms. The 70% unsupported diagnosis rate from RADV audits is the key empirical finding that reveals systematic gaming. All claims rated 'likely' based on CMS official projections and audit findings from government sources."

 PRIMARY CONNECTION: [[CMS 2027 chart review exclusion targets vertical integration profit arbitrage by removing upcoded diagnoses from MA risk scoring]]
 WHY ARCHIVED: Deepens the existing KB claim with mechanical detail about how risk adjustment actually works and how reforms target it.
 EXTRACTION HINT: The distinction between V28 (what gets coded) and chart review exclusion (how it gets coded) is structurally important — they're complementary reforms, not redundant.

+## Key Facts
+- CMS-HCC risk adjustment pays MA plans monthly per-member capitation adjusted by risk scores derived from diagnosis codes (HCCs)
+- Each HCC has a coefficient that increases payment for sicker patients
+- V28 implementation timeline: 2024-2026 gradual phase-in, complete by 2026
+- Nearly every major MA plan has faced or settled DOJ upcoding allegations
+- No UPCODE Act reintroduced in Congress (March 2025) with bipartisan support
