Medicare prescription drugs are mainly covered under Medicare Part D , and sometimes under Medicare Advantage (Part C) plans that include drug coverage , while Original Medicare (Part A and Part B) generally does not cover routine prescriptions.

Core answer

  • Medicare Part D is the primary part of Medicare that covers outpatient prescription drugs through stand‑alone drug plans or Medicare Advantage plans with drug coverage.
  • Some Medicare Advantage (Part C) plans bundle hospital, medical, and prescription coverage together, so your prescriptions may be covered through that single plan instead of a separate Part D.
  • Original Medicare (Part A and Part B) only covers very limited drug situations, like medications given during a hospital stay or certain drugs administered in a clinic, not your typical pharmacy prescriptions.

Quick Scoop: how coverage works

  • Part D (Drug plans):
    • Run by private insurers approved by Medicare.
    • Cover many common generic and brand‑name drugs listed on a plan’s formulary (its covered drug list).
* In 2026, Part D plans feature a maximum annual out‑of‑pocket drug cost of **$2,100** , after which the plan pays 100% of covered drugs for the rest of the year.
  • Part C with drug coverage (MA‑PD):
    • Combines Part A, Part B, and usually Part D‑like drug coverage in one plan.
* You typically use the plan’s pharmacy network and formulary for prescriptions.

When drugs are not under Part D

  • Part A may cover medications you receive as part of an inpatient hospital stay.
  • Part B may cover certain drugs you do not pick up at a retail pharmacy, such as some injectable drugs given in a doctor’s office, certain cancer drugs, and some insulins and supplies used with insulin pumps.

Simple checklist for you

  • If you use a stand‑alone drug card with Original Medicare → your prescriptions are under Part D.
  • If you carry a single Medicare Advantage card that says it includes drug coverage → your prescriptions are under that Part C plan’s drug benefit (Part D‑equivalent).
  • Drugs given in the hospital or infused in a clinic may fall under Part A or B , not your pharmacy drug plan.
