In short
- Part B covers a few drugs. Part D covers many more.
- For Part B drugs, you pay up to 20% after the deductible.
- If a drug is not covered, ask your plan for a coverage decision.
What this means
Medicare.gov says Part B (Medical Insurance) covers a limited number of outpatient prescription drugs under certain conditions, and Medicare drug coverage (Part D) covers many drugs that Part B doesn't cover [1].
For Part B drugs, you pay up to 20% of the Medicare-approved amount after you meet the Part B deductible [1]. Part D costs depend on your plan. Medicare.gov notes your drug plan won't charge a copayment or deductible for vaccines that ACIP recommends [1].
If your drug isn't covered, you can ask your Part D plan for a coverage decision. For a standard request for a drug, the plan must answer no later than 72 hours after it gets the request [2]. If the plan still says no, you can appeal (a redetermination). File it within 60 calendar days after you receive the written decision [3].
Your next step
check whether your drug is billed under Part B or on your Part D plan's drug list, then ask the plan for a coverage decision if it isn't covered [2].
