Medicare Part D coverage has four stages. You pay a share of the cost for your drugs in each stage up to a limit. You may not reach all stages. The cycle restarts each year.
Medicare Part D
Prescription drug coverage
Medicare Part D helps with the cost of prescription drugs.
You can get drug coverage with a standalone Part D plan or as part of a Medicare Advantage plan (Part C). Some plans have pharmacy networks and mail order pharmacies that offer discounted prices.
Plans are offered by private insurance companies approved by Medicare. Your choices vary depending on where you live. Coverage and costs beyond the standards set by Medicare vary from plan to plan.
You must be enrolled in Part A or Part B to be eligible for a Part D plan.
Medicare Part D plans cover:
- Types of drugs most commonly prescribed according to federal standards
- Specific brand name and generic drugs on the plan formulary, or list of drugs
- Commercially available vaccines not covered by Part B
- Annual deductible: You pay 100% of the cost up to the plan deductible amount.
- Initial coverage: You pay copay’s or coinsurance up to a set annual limit.
- Coverage gap (donut hole): You pay a percentage of the cost up to an
out-of-pocket annual limit.
- These annual limits are subject to change every year.
- Catastrophic coverage: You pay reduced copay’s for the rest of the year.
