+The chart review exclusion is projected to save over $7 billion in 2027 by eliminating diagnoses from unlinked chart review records. This is comparable to the $7.6 billion annual savings from the V28 model transition, suggesting chart review-based upcoding represents roughly half of the total payment inflation in MA risk adjustment. The dual reform (V28 + chart review exclusion) targets both what gets coded (diagnosis-to-HCC mappings) and how it gets coded (retrospective vs. encounter-linked capture), representing the most significant structural reform to MA risk adjustment since the program's inception.

+CMS Risk Adjustment Data Validation (RADV) audits find 70% of diagnosis codes submitted by MA plans are not supported by medical records. This provides empirical evidence that the majority of MA risk adjustment depends on codes that don't survive audit scrutiny, confirming that systematic upcoding is not an edge case but the structural norm. The industry's survival depends on CMS not auditing at scale, which explains the intensity of industry opposition to the chart review exclusion.

+In-home health assessments are explicitly identified as a diagnosis capture method designed to find codeable conditions rather than treat patients. These visits, along with retrospective chart reviews, represent systematic practices where the primary purpose is code generation for risk adjustment rather than clinical care delivery. The chart review exclusion targets retrospective record-mining, but in-home assessments represent a parallel capture method that remains unaddressed by the 2027 proposed rule, suggesting additional enforcement mechanisms may be needed to close this pathway.

+The V28 + chart review exclusion dual reform creates a structural advantage for purpose-built MA plans over acquisition-based vertical integrators. V28 narrows what can be coded (reducing the value of broad provider networks that capture marginal diagnoses), while chart review exclusion eliminates retrospective code-mining (reducing the value of owning medical records infrastructure). Purpose-built plans that optimize for encounter-linked diagnosis capture during actual care delivery face lower compliance risk than acquisition-based plans dependent on retrospective chart review. This regulatory shift explains why Devoted's technology-first model outperforms traditional vertical integration during the 2024-2027 CMS tightening period.

+# CMS chart review exclusion saves $7 billion annually by eliminating unlinked retrospective diagnosis capture from risk scoring
+
+CMS's proposed 2027 chart review exclusion would eliminate diagnoses from risk adjustment unless they are tied to a documented medical service encounter. This targets the specific practice of retrospective chart review—mining medical records for additional diagnosis codes without those codes being linked to actual clinical care.
+
+Under the proposed rule, diagnoses from chart reviews would only be allowed if tied to an actual medical encounter. Unlinked chart review records—those not associated with a documented service—would be excluded from risk score calculation entirely.
+
+CMS projects this change would save over $7 billion in 2027, comparable to the annual savings from the V28 model transition.
+
+## Evidence
+
+- 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 retrospective code-mining that inflates risk scores
+
+## Mechanism
+
+Chart review exclusion targets the method of diagnosis capture. Current practice allows MA plans to conduct retrospective reviews of medical records specifically to find additional codeable diagnoses, even when those diagnoses were not documented during the original clinical encounter. This creates an incentive to mine records for codes rather than document conditions during actual care delivery.
+
+The $7+ billion annual savings estimate suggests a substantial portion of current MA risk adjustment depends on this retrospective capture method.

+# CMS-HCC V28 model transition reduces diagnosis-to-HCC mappings, saving $7.6 billion annually by narrowing codeable conditions
+
+The V24 to V28 risk adjustment model transition represents a structural reform to what diagnoses generate Medicare Advantage payments. V28 significantly decreased the number of diagnosis codes that map to Hierarchical Condition Categories (HCCs) while increasing the total number of HCC categories, creating a narrower but more granular payment structure.

+CMS estimated V28 would save $7.6 billion in 2024 alone through this tightened mapping. The model is being phased in from 2024-2026, with complete transition by 2026.

+
+## Mechanism
+

+# CMS RADV audits find 70 percent of MA diagnosis codes unsupported by medical records, revealing systematic upcoding at scale
+
+Risk Adjustment Data Validation (RADV) audits conducted by CMS find that 70% of diagnosis codes submitted by Medicare Advantage plans are not supported by medical records when audited. This suggests the majority of MA risk adjustment is built on codes that don't survive documentation scrutiny.
+
+This finding has profound implications for MA economics: if true at scale, it means current MA payment levels depend on CMS not conducting comprehensive audits. The industry's financial model relies on a gap between submitted codes and auditable codes.
+
+## Evidence
+
+- CMS Risk Adjustment Data Validation (RADV) audits find 70% of diagnosis codes not supported by medical records
+- This represents systematic documentation failure across the MA industry
+- The gap between submitted codes and auditable codes is structural, not incidental
+
+## Implications
+
+The 70% unsupported rate explains why MA plans resist comprehensive RADV auditing and why the chart review exclusion proposal generates such strong industry opposition. If the majority of risk-adjusted payments depend on codes that wouldn't survive audit, then scaling up audit intensity or eliminating unlinked chart reviews threatens the core economics of the MA business model.
+
+This also contextualizes the DOJ False Claims Act cases against major MA plans—the enforcement actions aren't targeting edge cases but rather a systematic practice where unsupported diagnosis coding is the norm.

+# V28 model transition and chart review exclusion form dual reform targeting both what gets coded and how it gets coded
+
+The V28 model transition and chart review exclusion represent complementary structural reforms to Medicare Advantage risk adjustment, not redundant policies. V28 targets coding breadth—narrowing which diagnoses qualify for HCC mapping and payment. Chart review exclusion targets coding method—eliminating retrospective record-mining as a diagnosis capture pathway.
+
+Together, these reforms represent the most significant structural change to MA risk adjustment since the program's inception. Each saves approximately $7 billion annually, suggesting they address different mechanisms of payment inflation.
+
+## Evidence
+
+- V28 phase-in targets coding breadth (fewer mappable diagnoses): $7.6B annual savings
+- Chart review exclusion targets coding method (no retrospective code-mining): >$7B annual savings
+- Combined reforms address both what can be coded and how it can be captured
+- Industry warns of benefit cuts and market exits if combined with flat rates
+
+## Mechanism
+
+V28 narrows the universe of payable conditions by reducing diagnosis-to-HCC mappings. Even if a plan successfully documents a diagnosis, fewer diagnoses now generate payment. Chart review exclusion eliminates a capture method by requiring diagnoses to be linked to documented encounters. Even if a diagnosis qualifies under V28, it must be captured during actual care delivery, not retrospective record review.
+
+The dual reform closes both the "what" and "how" pathways that enabled systematic upcoding. This explains why industry response has been more severe than to either reform individually—the combination eliminates both the breadth of codeable conditions and the primary method of maximizing code capture.
