This high failure rate suggests that there are significant discrepancies between the data reported by these plans and the actual data, which could impact the accuracy of risk adjustment payments. -### CMS-HCC Risk Adjustment Mechanics (from multiple sources) +The RADV audits are part of CMS's efforts to ensure the integrity of the Medicare Advantage program by validating the data used to calculate risk scores. These audits are separate from those conducted by the Office of Inspector General (OIG), which also reviews Medicare Advantage data but through different methodologies and objectives. -**How it works:** -- CMS pays MA plans a monthly per-member capitation adjusted by risk scores -- Risk scores derived from diagnosis codes (HCCs — Hierarchical Condition Categories) -- Each HCC has a coefficient that increases payment for sicker patients -- Plans submit diagnosis codes annually; CMS calculates risk scores +The 70% failure rate in RADV audits highlights the need for improved data accuracy and compliance among Medicare Advantage plans. This issue is particularly relevant in the context of ongoing policy discussions about the future of risk adjustment and the potential impact of proposed changes, such as the CMS 2027 chart review exclusion. -**How it's gamed:** -- **Upcoding**: submitting more/higher-severity diagnoses than FFS Medicare would capture -- **Chart reviews**: retrospective review of medical records to find additional codeable diagnoses not documented during encounters -- **In-home health assessments**: visits specifically designed to capture diagnosis codes, not treat patients -- **Risk adjustment data validation (RADV)**: CMS audits find 70% of diagnosis codes not supported by medical records +While the RADV audits predate the 2027 policy proposal, they provide important context for understanding the challenges and implications of proposed changes to the risk adjustment process. The audits underscore the importance of accurate data reporting and the potential financial implications for plans that fail to meet CMS's standards. -### V24 to V28 Transition +--- +type: claim +title: V28 and chart review complementarity +confidence: likely +description: The V28 phase-in and chart review exclusion are complementary strategies in CMS's approach to risk adjustment, addressing different aspects of the process. +created: 2026-01-00 +processed_date: 2026-01-00 +source: commonwealth-fund +relevant_notes: [] +challenged_by: [] +--- -- V24: previous model with broader diagnosis-to-HCC mappings -- V28 (implemented 2024): significantly decreased diagnosis codes mapping to HCCs, increased number of HCCs -- Phase-in: 2024-2026 gradual transition, complete by 2026 -- CMS estimated V28 would save $7.6 billion in 2024 alone +The V28 phase-in and chart review exclusion represent complementary strategies in CMS's approach to risk adjustment for Medicare Advantage plans. While the V28 phase-in focuses on the methodology of calculating risk scores, the chart review exclusion addresses the data sources used in this calculation. -### 2027 Chart Review Exclusion +These strategies are orthogonal dimensions of CMS's risk adjustment policy, with V28 addressing the "how" of risk score calculation and chart review exclusion addressing the "what" of data inclusion. By tackling both the methodology and data sources, CMS aims to enhance the accuracy and fairness of risk adjustment payments. -- CMS proposes excluding all diagnoses from unlinked chart review records (not tied to documented service) -- Diagnoses from chart reviews allowed ONLY if tied to actual medical encounter -- Projected savings: **>$7 billion in 2027** -- Targets the specific practice of retrospective code-mining that inflates risk scores +However, industry stakeholders have raised concerns that the savings estimates from V28 and chart review exclusion may not be fully additive. Plans may adapt to one change in a way that reduces the impact of the other, potentially affecting the overall savings and effectiveness of these strategies. -### DOJ/OIG Enforcement - -- Nearly every major MA plan has faced or settled upcoding allegations -- DOJ uses False Claims Act against unsupported diagnostic codes -- No UPCODE Act reintroduced in Congress (March 2025) — bipartisan support -- 2025 CMS administrator confirmed rooting out upcoding is bipartisan priority - -### V28 + Chart Review Exclusion Combined Impact - -- V28 phase-in targets coding breadth (fewer mappable diagnoses) -- Chart review exclusion targets coding method (no retrospective code-mining) -- Together: most significant structural reform to MA risk adjustment since program inception -- Industry warns of benefit cuts and market exits if combined with flat rates - -## Agent Notes -**Why this matters:** The risk adjustment system is the mechanism through which MA plans extract above-FFS payments. Understanding the V24→V28 transition and chart review exclusion is essential for predicting MA's next 5-10 years. The $7B+ annual savings from chart review exclusion alone shows how much current payments depend on retrospective code-mining. -**What surprised me:** The 70% unsupported diagnosis rate from OIG audits. If true at scale, the majority of MA risk adjustment is built on codes that don't survive audit. The industry's survival depends on CMS not auditing at scale. -**KB connections:** [[CMS 2027 chart review exclusion targets vertical integration profit arbitrage by removing upcoded diagnoses from MA risk scoring]] -**Extraction hints:** Claims about: (1) chart review as the primary mechanism of systematic upcoding, (2) V28 + chart review exclusion as dual reform changing MA economics, (3) the 70% unsupported diagnosis rate as evidence of systemic gaming - -## Curator Notes -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. +Despite these concerns, the complementary nature of V28 and chart review exclusion reflects CMS's comprehensive approach to improving the risk adjustment process, ensuring that both the calculation methods and data sources are robust and reliable. \ No newline at end of file
