30.5 - No-Fault Responses
(Rev. 11550; Issued: 08-12-22; Effective: 10-13-22; Implementation:10-13-22)
The MSP Contractor conducts all no-fault investigations (See Chapter 3 and §10.8.1, above). If
Medicare is billed as primary payer, but the MSP Contractor indicates there is coverage under no-
fault insurance and the provider did not submit a satisfactory explanation to the development
request concerning why Medicare is billed as primary, the A/B MAC and the DME MAC denies the
claim.
