You can join a separate Medicare drug plan to get Medicare drug coverage
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:
Medicare Advantage is a Medicare-approved plan from a private company that offers an alternative to Original Medicare for your health and drug coverage.
In most cases, you’ll need to use doctors who are 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.
