There are two main categories of Medicare coverage including Original Medicare (with optional Medicare Supplement and prescription drug insurance) and Medicare Advantage (which provides benefits through private insurers).
Part A (Original Medicare) provides coverage for inpatient and hospital care.
Part B (Original Medicare) provides coverage for doctors and outpatient services.
Part C (Medicare Advantage Plan) typically covers Parts A, B and D with one bundled insurance policy for all Medicare coverage.
Part D (Medicare Prescription Drug Plan) provides coverage for the cost of your medications.
Plans A-N (Medicare Supplement or Medigap) coverage varies by plan benefits, but these plans help pay the costs that Medicare A and B don't cover. Plans C, E, F, H, I and J are no longer sold to new enrollees.
