Since the January release of CMS’s controversial final rule on Risk Adjustment Data Validation (RADV) audits, all has remained quiet on the litigation front. But in a complaint filed in a federal court on Sept. 1, Humana Inc. opens old wounds regarding the years-long leadup to the final rule and invokes the Administrative Procedure Act (APA) in asking the court to vacate the rule. In doing so, it seeks to stop CMS from applying its new audit policy of seeking extrapolated recovery amounts.
Issued on Jan. 30, the final rule (88 Fed. Reg. 6643, Feb. 1, 2023) pertains to contract-level audits that CMS began conducting more than a decade ago to verify the accuracy of payments made to MA organizations and recover improper payments. In that rule, CMS codified its plans to begin extrapolating RADV audit findings with payment year 2018 — but not findings for payment years 2011 through 2017, as once proposed. And the agency confirmed it would not adopt a “fee-for-service adjuster” to account for any impact from unaudited diagnosis codes in FFS data that are used to calibrate the MA risk adjustment model.
