Recommendation Followup: Michigan Did Not Report and Refund the Full Federal Share of Medicaid Overpayments

In a previous audit, OIG determined that Michigan did not properly report $1.3 million (Federal share) in Medicaid overpayments for Federal fiscal years (FYs) 2008 and 2009. We performed this audit as a followup to the previous audit. Specifically, we wanted to determine whether the Michigan Department of Health and Human Services (State agency) had reported the overpayments that we identified in the previous audit, as well as Medicaid overpayments identified in FYs 2011 through 2015.
