Part D – Prescription Coverage

While not part of Original Medicare, the Medicare Prescription Drug Plan (Part D) is very important. It provides coverage for prescription drugs which is offered under Medicare. You can either sign up for a Medicare Prescription Drug Plan (Part D) on its own or receive drug coverage through your Medicare Advantage Plan (Part C).  Each plan that offers prescription drug coverage through Medicare Part D must give at least a standard level of coverage set by Medicare. Plans can vary the list of prescription drugs they cover (called a formulary) and how they place drugs into different “tiers” on their formularies.
