Does Medicare Part A Cover Outpatient Surgery?

Medicare Part A does not cover outpatient surgery, but Part B covers medically necessary outpatient surgery. Medicare Advantage plans may also cover outpatient surgery and include an annual out-of-pocket spending limit, which Original Medicare doesn’t offer.

Does Medicare Cover Outpatient Surgery?

Medicare Part A typically covers inpatient surgery but usually doesn't cover outpatient operations.

Medicare Part B typically covers outpatient services, including doctor’s visits and outpatient surgery that is medically necessary.

Medicare Advantage (Part C) plans also cover outpatient surgery, and they also include an annual out-of-pocket spending limit. This can potentially save you money in out-of-pocket Medicare costs for your surgery.

Original Medicare does not include an out-of-pocket spending limit.

Is surgery covered by Medicare Part A?

Medicare Part A is hospital insurance, and it helps cover the costs of your inpatient stays at certain facilities, such as:

  • Hospitals
  • Skilled nursing facilities
  • Mental health facilities

If you receive surgery that requires an inpatient hospital stay, Medicare Part A will help cover your hospital costs after you meet your Part A deductible ($1,632 per benefit period in 2024).

If you receive a medically necessary surgery as an outpatient, Medicare Part B is responsible for covering some of the costs of your doctor’s services.

How much does outpatient surgery cost with Medicare?

Generally you'll pay 20% of that Medicare approved amount regarding your surgery, and then an additional 20% of the costs for your doctor. The Part B deductible is $240 in 2024, so once you hit the deductible then Part B coverage will kick in.

If Medicare Part B covers your outpatient surgery, you may still be responsible for certain out of pocket costs. 

  • Part B deductible
  • Part B coinsurance or copayment

Medicare Part B deductible for outpatient costs

The Medicare Part B deductible is $240 per year in 2024. You must meet this deductible before Medicare Part B coverage kicks in and covers your surgery costs for the rest of the year.

Medicare Part B coinsurance or copayment

After your Part B deductible is met through expenses you accrue as an outpatient, you usually are responsible for 20 percent of the Medicare-approved amount for most doctor’s services.

There is no annual limit on how much you could pay for the Part B coinsurance in a given year. This means that your Part B outpatient surgery coinsurance costs could add up quickly.

Medicare Advantage plans include annual out-of-pocket spending limits

Medicare Advantage plans are sold by private insurance companies as an alternative to Original Medicare (Medicare Part A and Part B).

Every Medicare Advantage plan must cover everything that Part A and Part B covers. This means that if your outpatient surgery is covered by Medicare Part B, it will also be covered by a Medicare Advantage plan.

The annual out-of-pocket spending limit that is included with all Medicare Advantage plans could potentially help you save money on your out-of-pocket costs related to outpatient surgery.
