Does Medicare Cover Bariatric Surgery?

Yes, Medicare covers bariatric surgery, but it is not automatic. To get coverage, you must meet strict medical criteria, including a body mass index (BMI) of 35 or higher and at least one related health condition, such as diabetes or heart disease. You must also have documented evidence that previous medical treatments for obesity were unsuccessful.

Bariatric surgery is a major medical procedure that alters your digestive system to help you lose weight. It is typically considered when diet and exercise haven't worked, or when you have serious health problems because of your weight. Medicare recognizes that obesity is a medical condition that can lead to severe complications, which is why they provide coverage for these procedures when medically necessary.

However, Medicare does not cover all types of weight-loss surgery. The procedures that are generally covered include Roux-en-Y gastric bypass surgery, laparoscopic adjustable gastric banding, and sleeve gastrectomy. Experimental procedures or surgeries performed strictly for cosmetic reasons are never covered. The surgery must also be performed at a facility that is certified by Medicare for bariatric surgery.

When it comes to Medicare, you have two paths, not two products. The real choice is Traditional Medicare (Parts A and B) versus Medicare Advantage (Part C). The path you choose will dictate how your bariatric surgery is covered, which doctors you can see, and how much you will pay out of pocket.

If you choose the Traditional Medicare path, Part A covers the inpatient hospital stay for the surgery. This includes your room, meals, nursing care, and the operating room costs. Part B covers the surgeon's fees, anesthesia, and any outpatient care you need before and after the surgery, such as nutritional counseling or physical therapy.

Under Traditional Medicare, you will be responsible for the Part A deductible for your hospital stay. For the Part B services, you will pay the Part B deductible and then 20% of the Medicare-approved amount for the surgeon and other medical services. Because bariatric surgery is expensive, that 20% coinsurance can add up to thousands of dollars.

This is why many people on the Traditional Medicare path add a Medicare Supplement (Medigap) plan. The supplement decision comes AFTER you choose Traditional Medicare - it's a component of the Traditional path, not an alternative to Advantage. A supplement fills the gaps by law, covering the 20% coinsurance and potentially the hospital deductible, depending on the plan you choose. With a comprehensive Medigap plan, your out-of-pocket costs for a major surgery like this can be reduced to almost zero.

If you choose the Medicare Advantage path, your plan must cover at least what Traditional Medicare covers. This means they must cover bariatric surgery if you meet the medical criteria. However, Advantage plans operate differently. They often require you to use their specific network of hospitals and surgeons. If your preferred bariatric surgeon is not in the network, you may have to pay the full cost yourself or find a different doctor.

Additionally, Medicare Advantage plans usually require prior authorization before the surgery is approved. This means your doctor must send paperwork proving that the surgery is medically necessary before the plan will agree to pay for it. Your out-of-pocket costs will depend on your specific plan's copays, coinsurance, and maximum out-of-pocket limits. You might pay a flat copay for the hospital stay and a percentage for the surgeon, up to your plan's annual limit.

Before you schedule any procedure, it is crucial to understand exactly what your coverage entails. You need to verify that your surgeon accepts Medicare, that the facility is Medicare-approved, and that you have met all the prerequisite criteria, such as documented medically supervised weight loss attempts.
