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

If you're an inpatient, you pay the Part A deductible [glossary] and coinsurance (if applicable).
If you're anoutpatient, you pay a copayment after you meet the Part B deductible.
In a freestanding clinic, you pay 20% of the Medicare-Approved Amount for the therapy, after you meet the Part B deductible.

Note:

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
If your doctor accepts assignment
The type of facility
Where you get your test, item, or service

Note:

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 if, or how much, Medicare will pay for them.
