Audit of the Arkansas Department of Human Services' Medicaid Prescription Drug Rebate Program

This final audit report points out that 72 drug manufacturers had disputed $768,962 of Medicaid drug rebate billings for drug purchases paid by the Arkansas Department of Human Services' (State agency) for the quarter ended March 31, 1992. A portion of the disputed amount, $282,205, was the result of a billing error by the State agency. The remaining $486,757 could be collected if the State agency pursued the disputes. We recommended actions the State could take to resolve the disputes and collect the amounts owed.
