Radiation therapy

Medicare Part A (Hospital Insurance)

 covers radiation therapy for hospital inpatients. 

Medicare Part B (Medical Insurance)

 covers this therapy for outpatients or patients in freestanding clinics.

Your costs in Original Medicare
  • As an inpatient, you pay the Part A deductible [glossary] and coinsurance (if applicable).
  • As an outpatient, you pay a copayment , and the Part B deductible applies.
  • For therapy at a freestanding facility, you pay 20% of the Medicare-Approved Amount for the therapy, and the Part B deductible applies.


To find out how much your test, item, or service will cost, talk to your doctor or health care provider. The specific amount you’ll owe may depend on several things, like:

  • Other insurance you may have
  • How much your doctor charges
  • Whether your doctor accepts assignment
  • The type of facility
  • Where you get your test, item, or service


Your doctor or other health care provider may recommend you get services more often than Medicare covers. Or, they may recommend services that Medicare doesn’t cover. If this happens, you may have to pay some or all of the costs. Ask questions so you understand why your doctor is recommending certain services and whether Medicare will pay for them.
