Submission of Hardcopy MSP Claims with Multiple Primary Payers

There may be situations where more than one primary insurer to Medicare makes payment on a claim; for example, an employer group health plan makes a primary payment for a service and, subsequently, another group health plan also makes a primary payment for the same service. Claims with multiple primary payers cannot be sent electronically to Medicare. A hardcopy claim must be submitted on Form CMS-1500. Physicians and suppliers must attach the other payers' explanation of benefits (EOB), or remittance advice (RA), to the claim when sending it to Medicare for processing.
