The Four Parts of Medicare

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 costs 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.
