In this episode of Health Law Simplified, we unpack a major shift in Medicare Advantage oversight: CMS’s sweeping expansion of its Risk Adjustment Data Validation (RADV) audit program. Beginning immediately, CMS will significantly expand its oversight by auditing all 550 eligible Medicare Advantage contracts each year – an ambitious leap from the previous annual review of just 60 plans. Hosts Sandy Durkin and Elizabeth Lippincott explore why CMS is cracking down, how it's scaling up with new technology and a 50-fold increase in medical coders, and what this means for health plans and providers. They break down the legal and financial implications of extrapolated audit findings, including the risk of large recoupments, and talk about their expectations for the extrapolation methodology for targeted audits.  This episode offers critical insights and practical steps to prepare for one of the most consequential oversight changes Medicare Advantage plans have seen.
