Medicare Secondary Payer (MSP)

Medicare Secondary Payer (MSP) is the term used to describe when another payer is responsible for paying a beneficiary's claims before Medicare pays. Noridian protects and preserves the Medicare Trust Fund by ensuring that Medicare benefits are coordinated with all other appropriate payers and Medicare pays only when and what it should pay.
