What do I do if I have been overpaid because of a duplicate primary payment
Q. What do I do if I have been overpaid because of a duplicate primary payment?
A. Medicare Secondary Payer (MSP) overpayments are processed differently than non-MSP overpayments and require a refund to be sent within sixty days of receiving a duplicate payment. Complete the appropriate Medicare Secondary Payer overpayment refund form (see below) and attach a check for the overpaid amount. In addition, the other insurer’s explanation of benefits is required for every claim involved.
Refer to the Medicare Secondary Payer FAQs for more information on MSP overpayments and how to determine the MSP overpayment amount.
