State Data for the Medicare Modernization Act (MMA) (CMS-10143)

The Medicare Advantage Prescription Drug (MAPD) State User Guide contains technical guidance for the state and file layouts of the MMA Request (state sends to CMS) and Response (CMS returns to state) files. Please see the attached Crosswalk and Track Change version of the guide for details. The MMA request file identifies all dually eligible beneficiaries in the state for the current month. As noted above in section A1, the phase-down process requires a monthly count of all full-benefit dually eligible beneficiaries with a dual status code of 02, 04, and 08 and an active Part D plan enrollment in the month.
