More questions, answered

What counts as creditable drug coverage?

Creditable coverage is drug coverage expected to pay, on average, at least as much as standard Medicare drug coverage. Employer, union, VA and some other plans tell members every year whether their coverage is creditable. If it is, you can delay Part D without a late penalty, but keep the notice as proof.

How is the Part D late penalty calculated?

The penalty is based on how many full months you went without Part D or other creditable coverage after you were first eligible. It is added to your monthly premium for as long as you have Medicare drug coverage. People who qualify for Extra Help do not pay the penalty.

Do I need Part D if I take no medicines now?

Many people still enroll in a low-cost plan, because health can change quickly and a late penalty could apply if you join later. Part D also protects you from the full price of a new expensive drug. Weigh the yearly premium against that risk, and remember you can only join at set times.

Can I use drug discount cards instead of Part D?

Discount cards and pharmacy discount programs can sometimes lower the price of a single generic drug, but they are not insurance and do not protect you from high costs. Purchases made with them usually do not count toward your Part D deductible or yearly cap. They are not creditable coverage, so relying on them can lead to a late penalty.

Will Extra Help affect my other benefits?

Extra Help does not reduce your Social Security benefits. Its value is generally not counted as income for other federal programs. It also cannot be recovered from your estate. If you are unsure how it interacts with other help you get, ask a SHIP counselor or Social Security.

What if my plan stops covering a drug I take?

Plans must give advance notice of most formulary changes, and the Annual Notice of Change lists changes for next year. You can ask your doctor about an alternative, request an exception, or switch plans during Open Enrollment. If a drug is removed for safety reasons, the plan may act more quickly.
