According to a recent OIG report, "Review of Medicare Payments to Prescription Drug Plans on Behalf of Deceased Enrollees," CMS has yet to collect approximately $3.61 million in improper payments made to Medicare Part D prescription drug plans on behalf of deceased Medicare enrollees. The OIG observes that while CMS had correctly stopped payments for the vast majority of deceased enrollees, its systems did not always identify and prevent the improper payments. The OIG recommended that CMS recoup improper payments in a timely manner and implement system enhancements to prevent and detect future improper payments for deceased enrollees.
