The Medicare Part D program provides an outpatient prescription drug benefit to more than 50 million older adults and people with long-term disabilities in Medicare who enroll in private plans, including stand-alone prescription drug plans (PDPs) to supplement traditional Medicare and Medicare Advantage prescription drug plans (MA-PDs) that include drug coverage and other Medicare-covered benefits.

The brief explains why the stability of the PDP market matters, both for people in traditional Medicare who want prescription drug coverage but also for the viability of traditional Medicare as an option vis a vis Medicare Advantage.
