Medicare Advantage Risk Adjustment Data Validation Program

About the Program

The Medicare Advantage (MA) Risk Adjustment Data Validation (RADV) program is CMS' primary way to address overpayments to Medicare Advantage Organizations (MAOs). During a MA RADV audit, CMS confirms that any diagnoses submitted by an MAO for risk adjustment are supported in the enrollees' medical records. If diagnoses are unsupported by the medical records, CMS may collect overpayments. MA RADV audits occur after the final risk adjustment data submission deadline for the MA contract year.

Questions about the MA RADV program should be sent to: RADV@cms.hhs.gov
