What is a Prescription Drug Plan (Part D)?

Medicare Part D refers to optional prescription drug coverage. This is not covered by Original Medicare or Medicare Supplement plans, but is often included with Medicare Advantage plans.  You can purchase separate stand-alone Part D coverage plans.

Anyone who is eligible for Medicare can enroll in a Medicare Part D plan. 

These are plans that help pay for prescription medications, and are only available from private insurance companies, with oversight by CMS.
