For many people, having a surgical procedure for any number of reasons is common. But for older Americans, it’s a valid question to ask if Medicare covers surgery. Then, if so, what exactly does the program deem worthy of coverage?

Besides Original Medicare, there are also Medicare Advantage and Medicare Supplemental plans that can increase your benefits for surgeries. Continue reading to find out about your options comprehensively.

Medicare coverage for surgery?

Medicare covers many different types of surgeries, both inpatient and outpatient. However, the specifics of coverage vary depending on your Medicare plan type.

In general, Medicare will cover surgeries deemed medically necessary. This means that surgery is necessary to treat an illness or injury, and no other treatment option is available.

Discuss all of your options with your doctor if you’re considering surgery. They can help you decide what options are available and if surgery is necessary.

Medicare Advantage coverage for surgeries

On a Medicare Advantage plan, your coverage for surgery will likely be different than if you have Original Medicare or a Medicare Supplement plan. Medicare Advantage plans pay instead of Original Medicare.

They must offer coverage at least as good as Original Medicare and usually include benefits Medicare doesn’t. It’s essential to read the details of coverage for your specific plan.

Medicare Supplement coverage for surgeries

Medicare Supplement plans are private insurance plans that work with Original Medicare. They help pay for some of the costs not covered by Original Medicare. Like Medicare Advantage plans, each Medicare Supplement plan is different.

Outpatient surgery

Original Medicare, Medicare Advantage, and Medicare Supplement plans will generally cover outpatient surgeries. Outpatient means that the surgery will be performed in a hospital, but you won’t have to stay overnight in most cases.

There are exceptions to this rule, so be sure to read the details of your specific plan.

Outpatient surgery in an ambulatory surgical center

Outpatient ambulatory surgical centers are equipped to provide surgical care and procedures. Generally, patients are released from these facilities within 24 hours. Medicare Part B (Medical Insurance) covers the costs associated with approved surgical procedures received at these centers.

In many cases, surgeries in these locations are less expensive than being performed as an outpatient in a hospital.

Medicare and outpatient surgery

Suppose you are on Original Medicare and have surgery. You’ll pay the Part B deductible. Once you’ve met the Part B deductible, you will be responsible for 20% of the bill and any excess charges.

Medicare Advantage and outpatient surgery

Most Medicare Advantage plans have set copays for outpatient surgery. The copay can vary depending on where the procedure is performed. For example, a surgery being performed at the hospital could have a different cost than the surgery performed at a surgery center.

Medicare Supplement and outpatient surgery

Medicare supplements pick up your portion of the costs left to you by Original Medicare. This means depending on the plan letter, you should have little or nothing to pay out of pocket for covered surgeries.

Inpatient surgery

Medicare covers inpatient surgeries, so you must stay in the hospital overnight. Most inpatient surgeries are emergency surgeries, but most surgeries occur in an outpatient setting.

Medicare will cover inpatient surgery. Once you meet your Medicare Part A deductible, Medicare should cover most inpatient surgical costs. Additional coinsurance may be a requirement depending on the situation, the length of your stay, etc.

Medicare Advantage and inpatient surgery

Medicare Advantage plans typically have a per-day hospital copay. They also have a separate copay for inpatient surgery.

Medicare Supplement and inpatient surgery

Most Medicare Supplement plan letters will cover all inpatient surgery costs. Check your plan letter benefits to verify how much coverage you have.

Does Medicare pay for elective surgery?

Medicare will only pay for surgery if it’s medically necessary. While it’s possible to have an elective surgery that is also necessary, it’s rarer than normal surgery.

Get a Medicare plan to cover surgery costs

Medicare covers a lot, but not everything when you have a necessary surgical procedure. If you are not interested in paying the remaining 20%, it might be a great idea to explore getting a Medicare Supplemental plan. For a monthly premium, it’s possible to pay very little — or nothing — out of pocket should surgery be on the horizon.
