The drugs covered by a Part D plan vary depending on the plan and the insurance provider. However, all Part D plans have a list of the prescription drugs they cover. This is known as a formulary. The formulary contains all the prescription drugs covered and are classified into different groups. It is important to check each plan carefully to ensure it covers the drugs you need before purchasing it.
Medicare requires Part D plans to cover at least two prescription drugs from each class or category. Part D plans must also cover most, if not all, of drugs that fall into these specific categories:
- HIV medications
- cancer treatment drugs
However, Part D plans do not cover dietary supplements, weight control drugs, hair loss treatments, and over-the-counter medications.
