CMS Pub. 100-05, ch. 5, § 10.7
Additional Activities Arranged by Non-GHP MSP Type
The A/B MACs and DME MACs retain the responsibility of handling phone and written
correspondence/inquiries related to existing no-fault insurance (automobile no-fault insurance of all
types, including personal injury protection/med-pay), workers' compensation (WC), and liability cases,
unless the phone call or written correspondence reveals information discrepant with that on CWF.
The MSP Contractor shall handle all calls and written correspondence where a beneficiary, third party
payer, provider, or attorney is initially reporting the existence of a no-fault, WC, or liability case. The
MSP Contractor shall develop all information necessary to establish an MSP occurrence. These
auxiliary records shall appear on CWF.
After the MSP Contractor has established a new case (i.e., added a "Y" auxiliary record), all follow -
up calls are the responsibility of the MSP Contractor.
A/B MACs and DME MACs are reminded that they may have overlapping MSP periods for
liability, no-fault, workers' compensation, and/or group health plan insurance.
