The Centers for Medicare & Medicaid Services Had Not Recovered More Than a Billion Dollars in Medicaid Overpayments Identified by OIG Audits

In a previous review, OIG determined that CMS had recovered the majority of Medicaid overpayments that we had identified in audit reports issued during Federal fiscal years (FYs) 2000 through 2009. However, millions of dollars remained uncollected at the time we issued our report. We performed the current audit as a followup to the previous audit to determine whether CMS recovered Medicaid overpayments for a more recent period, as well as remaining overpayments in the previous audit. Our objective was to determine whether CMS recovered overpayments identified in OIG audit reports in accordance with Federal requirements.
