Prescription drug coverage and Medicare Part D

Medicare drug coverage is available through standalone Part D plans and many Medicare Advantage plans. Each plan has its own covered-drug list, pharmacy network, and cost-sharing rules.

The short answer

How does Medicare prescription drug coverage work?

Medicare Part D helps cover outpatient prescription drugs through private plans. Each plan has a formulary, cost tiers, participating pharmacies, and possible requirements such as prior authorization or step therapy. A useful comparison checks every medication and pharmacy rather than relying only on the monthly premium.

Start with your current prescriptions

A plan's formulary lists the drugs it covers. Covered drugs are often grouped into tiers that affect what you pay. Drug names, dosages, quantities, and preferred pharmacies can all change the comparison.

Check every prescription, including the exact dosage and form.
Review preferred and standard network pharmacies.
Look for prior authorization, step therapy, or quantity limits.
Consider the full year's estimated drug costs, not only the premium.

Coverage can change

Formularies and pharmacy arrangements can change. Plans must follow notice and transition rules, but you should review your coverage during each Annual Enrollment Period and whenever your medications change.

Avoid an unplanned coverage gap

Going without creditable drug coverage after you become eligible may result in a late-enrollment penalty. Ask an employer plan whether its drug coverage is creditable before delaying Part D.
