  • HIV medications
  • antidepressants
  • cancer treatment medications
  • immunosuppressants
  • anticonvulsants
  • antipsychotics

Most plans also cover the majority of vaccines with no copay.

A Part D plan can change the medications or pricing on their coverage list at any time for several reasons, such as:

  • a generic of a brand becomes available
  • the price of brand may change if a generic becomes available
  • a new medication has become available or there’s new data about this treatment or medication
