Short Answer
The four parts of Medicare are Part A, Part B, Part C, and Part D.
- Part A covers inpatient/hospital coverage.
- Part B covers outpatient/medical coverage.
- Part C covers Part A, Part B, and sometimes Part D Prescription Drug coverage combined into one plan.
- Part D provides prescription drug coverage.
Original Medicare Parts A and B provide important health care coverage but don’t cover everything. That’s why most people choose additional Medicare coverage, Medicare Advantage Plans, or Supplement plans to help fill these gaps.
