En español | A formulary is the list of drugs your plan covers. Plans must offer a range of drugs in most therapeutic categories (e.g., beta blockers, diuretics and other classes) and they must cover all or nearly all drugs in six classes: antidepressants, antipsychotics, anticonvulsants, antiretrovirals (for HIV/AIDS), immunosuppressant (for transplants) and anticancer drugs. A plan sponsor with multiple plans can offer a different formulary for each.

Different sponsors will also have different formularies. There is no national formulary within Part D.
