Medicare Secondary Payer (MSP) is the term given to describe situations where Medicare does not pay first on a claim. Medicare is the secondary payer for beneficiaries who are covered by other types of health insurance or plans.
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.
Reporting an MSP overpayment to Medicare without submitting a payment:
The MSP Inquiry Form must be submitted along with the primary insurer EOBs. To ensure timely processing of your request, this form should be used for any Medicare Secondary Payer (MSP) request pertaining to Primary or Secondary payment of claims.
Reporting an MSP overpayment to Medicare with payment:
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. For more information on MSP Voluntary Refunds and the forms to submit, please see the "Submit a Voluntary Refund" section this site.
