Refunding Medicare for Overpayments
When your office receives a primary Medicare payment in addition to a primary Group Health Plan payment or an Accident Insurance payment, a refund should be made to Medicare for the overpayment. When a refund is due to Medicare, please send a check for the overpayment made payable to the Medicare Trust Fund, along with the beneficiary's name, Medicare number, and an explanation of the overpayment. If refunding less than the full Medicare payment received, an explanation of benefits from the primary insurer should be included. Submitting this information when refunding Medicare for an overpayment will help us process the refund correctly.
