Medicare Secondary Payer (MSP) eServices Tab
When a beneficiary has a primary payer other than Medicare, the Medicare Secondary Payer (MSP) tab provides the beneficiary’s primary insurance information. The MSP tab only displays active MSP data per the date(s) requested and will not be accessible if there is no MSP data or if notification of coverage primary to Medicare has not been received by CMS. To make sure you see all of the information, enter a date range in the inquiry screen. The HETS 270/271 system we are required to access for eligibility allows allow date requests up to 12 months in the past.
