A Medicare Secondary Payer (MSP) situation occurs when Medicare is not the primary payer. In MSP situations, another insurance (employer, workers compensation, liability insurance) pays first, and Medicare pays second. Medicare has the right to recover payments it made when it should have been the secondary payer.
