# CMS exploring AI-powered risk adjustment to detect upcoding patterns across population-scale data
|
|
|
|
CMS signals in the 2027 Advance Notice that it is exploring next-generation AI-powered risk adjustment models as part of broader Star Ratings and quality measurement modernization. If implemented, AI-based risk adjustment would fundamentally change the coding enforcement game because AI can detect upcoding patterns across millions of records simultaneously—a capability that traditional audit sampling cannot match.
|
|
|
|
Current risk adjustment relies on retrospective audits of small samples, which creates a cat-and-mouse game where plans optimize coding up to the audit detection threshold. AI-powered risk adjustment could shift this dynamic by analyzing population-scale patterns in real-time, making systematic upcoding detectable and unprofitable.
|
|
|
|
## Evidence
|
|
|
|
**CMS Signals (from 2027 Advance Notice):**
|
|
- CMS is exploring AI-based risk adjustment as part of modernization efforts
|
|
- Also exploring alternative data sources and timeline compression to reduce current 2-year lag between measurement and payment
|
|
- Part of broader Star Ratings reform package including new depression screening and follow-up measure (2027 measurement year, 2029 ratings)
|
|
|
|
**Structural Implications:**
|
|
- Traditional audit sampling reviews small fractions of claims, creating optimization space for plans
|
|
- AI could analyze 100% of claims across all plans simultaneously, detecting statistical anomalies
|
|
- Would shift enforcement from retrospective penalty to prospective prevention
|
|
|
|
## Why This Remains Speculative
|
|
|
|
1. CMS has not published technical specifications or implementation timeline
|
|
2. Implementation would require resolving significant privacy and due process questions
|
|
3. AI model transparency and explainability requirements for regulatory use are unresolved
|
|
4. Industry will likely challenge any AI-based adjustment methodology through administrative and legal processes
|
|
5. Single source (CMS Advance Notice) signals exploration but not commitment
