Welcome to our comprehensive guide on Medicare coverage for bariatric surgery. If you or a loved one is considering this procedure, it’s important to understand the Medicare guidelines and requirements. In this article, we will provide you with all the information you need to know about Medicare coverage for bariatric surgery, including eligibility criteria, covered procedures, and potential costs.

Understanding Bariatric Surgery

Bariatric surgery, also known as weight loss surgery, is a medical procedure that helps individuals who are severely overweight or obese to lose weight. This type of surgery involves making changes to the digestive system, which can result in significant weight loss and improvement in obesity-related health conditions. Bariatric surgery is generally recommended for individuals who have been unsuccessful in achieving weight loss through other methods, such as diet and exercise.

Medicare Coverage for Bariatric Surgery

Medicare provides coverage for bariatric surgery, but certain criteria must be met for the procedure to be covered. Here are the key points to consider:

Eligibility Criteria

To be eligible for Medicare coverage for bariatric surgery, you must meet the following criteria:

  • You are at least 18 years old
  • You have a body mass index (BMI) of 35 or higher
  • You have at least one obesity-related health condition, such as diabetes or high blood pressure
  • You have previously attempted and failed to achieve weight loss through non-surgical methods

Covered Procedures

Medicare covers the following bariatric surgery procedures:

  • Gastric bypass surgery: This procedure involves creating a small pouch at the top of the stomach and bypassing a portion of the small intestine.
  • Sleeve gastrectomy: In this procedure, a large portion of the stomach is removed, leaving a smaller sleeve-shaped stomach.
  • Laparoscopic adjustable gastric banding: This surgery involves placing an adjustable band around the upper part of the stomach to create a smaller stomach pouch.

Costs and Coverage

Medicare covers a significant portion of the costs associated with bariatric surgery. However, it’s important to note that you may still be responsible for some out-of-pocket expenses. Here’s a breakdown of the costs:

  • Medicare Part A: If the surgery is performed in a hospital, Part A covers the hospital stay and related costs.
  • Medicare Part B: Part B covers the surgeon’s fees and other outpatient services related to the surgery.
  • Medicare Part D: If you require prescription medications after the surgery, Part D may cover the cost of those medications.

It’s crucial to review your specific Medicare plan and consult with your healthcare provider to understand the exact coverage and potential costs associated with bariatric surgery.


In conclusion, Medicare provides coverage for bariatric surgery for eligible individuals who meet the specified criteria. Understanding the requirements and covered procedures is essential when considering this weight loss option. If you believe you meet the eligibility criteria, consult with your healthcare provider to explore the possibilities of bariatric surgery under Medicare coverage.
