extraction_notes: "Extracted three new claims about V28 mechanics, chart review as primary upcoding mechanism, and the complementary nature of V28 + chart review exclusion reforms. 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."

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 scores derived from diagnosis codes submitted annually by MA plans
- 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
- Nearly every major MA plan has faced or settled upcoding allegations
