Prescription Drug Coverage

Medicare Prescription Drug plans are offered by government-approved private insurance companies and cover your prescription drug costs for covered medications. Coverage and costs beyond the standards set by Medicare can vary and your choices depend on where you live.

Part D

Medicare Part D

Most Part D plans have a list of covered prescription drugs (formularies) and may also have a network of pharmacies in your area.


Premiums are paid to the private insurer and vary by plan and can change
each year.


Plans may have a deductible and amounts vary from plan to plan.


Plans may require a copay each time you fill a prescription.


A cost share may apply each time you fill a prescription.

Coverage gap

Although plan designs can vary, most Part D plans have a cost share component commonly known as a coverage gap or “donut hole.” The coverage gap is a temporary limit where you are responsible for a higher percentage of your drug costs until you reach the plan’s annual out-of-pocket limit. After you reach the limit, you will pay a small share of your prescription costs for the remainder of the year.
