Medicare Secondary Payer Manual (Pub. 100-05), Ch. 5 § 10.7.1
No-Fault Development
10.7.1 - No-Fault Development
(Rev. 11550; Issued: 08-12-22; Effective: 10-13-22; Implementation:10-13-22)
If Medicare is billed as primary payer, but there is an indication of possible coverage under no-fault
insurance (including automobile no-fault insurance of all types, including personal injury protection)
the A/B MACs and DME MACs shall advise the MSP Contractor through the ECRS. The MSP
Contractor develops to determine whether there is coverage primary to Medicare through a form of
no-fault insurance (including automobile no-fault insurance of all types, including personal injury
protection). If there is coverage available, the MSP Contractor shall post an open "Y" auxiliary
record on CWF.
If, upon further investigation, the MSP Contractor learns that the beneficiary is filing a liability
insurance claim, the MSP Contractor shall create a new MSP record (with a +1-day difference in the
Effective Date.) for the liability situation.
