GAO: Medicaid: CMS Should Ensure That States Clearly Report Overpayments

States recovered $9.8 million in Medicaid overpayments, but they did not clearly report the overpayments and the return of the federal share to the Centers for Medicare & Medicaid Services (CMS) within the Department of Health and Human Services (HHS). Federal audits initially identified about $20.4 million in potential Medicaid overpayments across the 19 states with identified overpayments from June 2007 through February 2012. Of the $13.3 million in net overpayments, states recovered $9.8 million and were in the process of recovering the remaining $3.5 million.
