I Have Determined I Have Been Overpaid

A voluntary refund should be returned to Medicare anytime an overpayment has been identified by the provider.

• Voluntary refunds can be MSP- or non-MSP-related
• Payment by check or through eServices is required to be submitted along with the appropriate form
• The payment will be applied to the identified overpayments. If there are excess funds, they will be applied to other eligible outstanding overpayments.

A Medicare Secondary Payer (MSP) overpayment can occur when Medicare has processed and paid a claim as the primary payer, but should have paid as secondary.

• In order to report an MSP overpayment to Medicare without submitting a payment, the MSP inquiry form must be submitted along with the primary insurer EOBs
• If you are submitting a payment along with the disclosed overpayment, the appropriate MSP voluntary refund form must be submitted along with the primary insurer EOBs
