Medicare Part D Premium Payment (MDPP) Assistance 

The Medicare Part D Premium Payment Program (MDPP) pays Part D and Medigap insurance premiums for persons living with HIV/AIDS who are enrolled in the AIDS Drug Assistance Program (ADAP) and a Medicare Part D prescription drug plan. Individuals that are enrolled in MDPP are also eligible for the medical out-of-pocket (MOOP) cost benefit, which covers outpatient MOOP costs that count towards the client's health insurance policy's annual out of pocket maximum.
