myCGS: Submitting a Part B Medicare Secondary Payer (MSP) eClaim

The myCGS eClaim option allows all Medicare Part B providers to submit electronic claims via the web portal. This option is available to all providers, regardless of whether your office or practice currently submits Part B claims to CGS via Electronic Data Interchange (EDI), using PC-ACE Pro32 electronic filing software, or if you are still approved to file paper claims.

Medicare Secondary Payer (MSP) claims are also accepted through this option.

When the secondary option is selected, additional fields of the eClaim are displayed.
