Are we required to submit our Medicare Secondary Payer (MSP) claims electronically?

Answer:
Yes. Unless you have been approved to submit hard copy claims to Medicare, submit all Medicare claims electronically, including Medicare Secondary Payer (MSP) claims. An exception to this requirement is when a patient has two or more payers who are primary to Medicare. In situations where Medicare is the tertiary payer, these claims may be submitted hard copy.

The ASC v5010 format allows for electronic submission of primary payer information for MSP claims. Palmetto GBA also offers the PC-ACE Pro32 EDI billing software, which supports electronic submission of MSP claims.
