Ambulatory surgical centers

Medicare Part B (Medical Insurance)

 covers the facility service fees related to approved surgical procedures provided in an ambulatory surgical center (facility where surgical procedures are performed, and you’re expected to be released within 24 hours).

Your costs in Original Medicare

You pay the Part B 

deductible [glossary]

 and 20% of the 

Medicare-Approved Amount

 to both the ambulatory surgical center and the doctor who treats you. You pay nothing for certain preventive services. You pay all facility charges (sometimes called the "facility fee") for procedures Medicare doesn't cover in ambulatory surgical centers.

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.
