This final audit report discloses that Medicare accounts receivable credit balances included unidentified overpayments totaling an estimated $919,826 in the State of Wisconsin. The overpayments occurred because both hospitals and Blue Cross and Blue Shield United of Wisconsin (BCBSUW) did not adequately review credit balances and process adjustments timely. We are recommending recovery of the overpayments and procedural improvements to ensure that the hospitals and BCBSUW perform more adequate and timely reviews.
