Enriched existing chart review exclusion claim with mechanical detail about 70% unsupported diagnosis rate and $14+ billion combined annual impact. Source provides the detailed risk adjustment mechanics that explain HOW the payment inflation happens, not just that it happens. The distinction between V28 (what gets coded) and chart review exclusion (how it gets coded) is structurally important for understanding why both reforms are necessary."
+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."

-- V28 implementation: 2024-2026 three-year phase-in period
-- DOJ uses False Claims Act against unsupported MA diagnostic codes
-- No UPCODE Act reintroduced March 2025 with bipartisan support

+- 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
