Original Medicare:

  • Original Medicare includes Part A and Part B.
  • You can join a different Medicare drug plan to get Medicare drug coverage (Part D).
  • You can use any doctor or hospital that takes Medicare anywhere in the U.S.
  • To help pay your out-of-pocket costs in Original Medicare (like your 20% coinsurance), you can also buy supplemental coverage, like Medicare Supplement Insurance (Medigap), or have coverage from a former employer or union, or Medicaid.

Medicare Advantage (also known as Part C):

  • Medicare Advantage is a Medicare-approved plan from a private company that offers an alternative to Original Medicare for your health and drug coverage. These “bundled” plans include Part A, Part B, and usually Part D.
  • In most cases, you’ll need to use doctors in the plan’s network.
  • Plans may have lower out-of-pocket costs than Original Medicare.
  • Plans may offer some extra benefits that Original Medicare doesn’t cover — like vision, hearing, and dental services.
