Home » Resources » Can Medicare Cover Gastric Sleeve Surgery?

We understand that navigating the world of healthcare and insurance coverage can be complex and overwhelming, especially when it comes to specialized procedures like gastric sleeve surgery. If you’re considering this weight loss surgery and are wondering if Medicare covers it, you’ve come to the right place. In this comprehensive guide, we will delve into the topic of Medicare coverage for gastric sleeve surgery and provide you with the information you need to make informed decisions.

Understanding Gastric Sleeve Surgery

Before we explore the specifics of Medicare coverage, let’s start by understanding what gastric sleeve surgery entails. Gastric sleeve surgery, also known as sleeve gastrectomy, is a surgical procedure that involves the removal of a portion of the stomach, creating a smaller, sleeve-shaped stomach. This procedure aims to help individuals with obesity achieve significant weight loss by restricting the amount of food they can consume.

Medicare Coverage for Gastric Sleeve Surgery

Medicare is a federal health insurance program primarily designed for individuals who are 65 years or older, certain younger individuals with disabilities, and people with end-stage renal disease. Understanding Medicare coverage for gastric sleeve surgery requires looking at different parts of the program.

  • Medicare Part A: This part of Medicare covers hospital stays and certain inpatient procedures. However, gastric sleeve surgery is typically an outpatient procedure, so Medicare Part A coverage may not apply directly to the surgery itself.
  • Medicare Part B: Part B covers outpatient services, including some surgical procedures. While gastric sleeve surgery is generally considered an outpatient procedure, it’s crucial to note that Medicare Part B does not cover weight loss surgery solely to improve appearance. Medicare requires specific medical criteria to be met for coverage eligibility.
  • Medicare Part C (Medicare Advantage): Medicare Advantage plans, offered by private insurance companies approved by Medicare, must provide at least the same coverage as Original Medicare (Part A and Part B). Some Medicare Advantage plans may offer additional coverage for weight loss surgeries like gastric sleeve, but it’s essential to review the plan’s specific benefits and consult with the insurance provider.
  • Medicare Part D: Part D covers prescription drugs. While it may not directly cover gastric sleeve surgery, it could potentially cover medications related to the surgery, such as pain relievers or antibiotics.

It’s important to remember that Medicare coverage for gastric sleeve surgery can vary depending on factors such as individual circumstances, the state you reside in, and the specific Medicare plan you have. To determine your eligibility and coverage, it is advisable to contact Medicare directly or consult with a healthcare professional.

Additional Considerations

In addition to understanding Medicare coverage, there are several other factors to consider when contemplating gastric sleeve surgery:

  • Medical Necessity: Medicare typically requires that weight loss surgery be deemed medically necessary, meaning it is essential for the treatment of a particular medical condition related to obesity. Documentation from your healthcare provider regarding the medical necessity of the surgery may be required.
  • Pre-Approval and Documentation: Before undergoing gastric sleeve surgery, it is crucial to follow the pre-approval process outlined by Medicare. This often involves obtaining documentation from your healthcare provider, such as medical records, test results, and a detailed plan of care.
  • Cost Sharing and Out-of-Pocket Expenses: Even if Medicare covers gastric sleeve surgery, there may still be out-of-pocket costs involved. These costs can include deductibles, coinsurance, and copayments. Understanding your financial responsibilities and potential expenses is essential for making informed decisions.
  • Medicare Reimbursement Rates: It’s worth noting that Medicare sets reimbursement rates for covered services, which may vary from the actual cost of the surgery. Familiarizing yourself with Medicare reimbursement rates can help you estimate your potential financial obligations accurately.


  • Medicare coverage for gastric sleeve surgery can vary depending on individual circumstances and the specific Medicare plan.
