For many seniors, weight management is an important part of maintaining overall health and reducing the risk of chronic conditions. But with so many weight-loss options available, it can be confusing to know which programs or treatments might be covered by Medicare. It’s important to learn what is and isn’t covered, so you can make informed decisions about your health and wellness.
Weight Loss Services Medicare Covers
1. Obesity Screening & Intensive Behavioral Counseling (Part B)
Medicare Part B covers obesity screening and Intensive Behavioral Therapy (IBT) for beneficiaries with a Body Mass Index (BMI) of 30 or higher. This service must be provided by a qualified healthcare provider in a primary care setting.
Covered Sessions
- One session per week for the first month
- One session every other week for months two through six
- One session per month for months seven through twelve, provided the beneficiary has lost at least 6.6 pounds (3 kilograms) during the first six months
Providers use the 5-A behavioral counseling model: Assess, Advise, Agree, Assist, Arrange. These sessions are fully covered if the provider accepts Medicare assignment, though the Part B deductible may apply.
2. Bariatric (Weight-Loss) Surgery (Part A)
Medicare covers bariatric surgery for beneficiaries with a BMI of 35 or higher who also have at least one obesity-related health condition such as diabetes, high blood pressure, or sleep apnea. Additionally, patients must demonstrate that non-surgical weight-loss methods have failed.
Covered Surgical Procedures
- Gastric bypass
- Sleeve gastrectomy
- Adjustable gastric banding
- Biliopancreatic diversion with duodenal switch
Cosmetic weight-loss procedures are not covered. Beneficiaries are responsible for standard inpatient deductibles and coinsurance for these procedures.
What Medicare Does Not Cover
Commercial Weight-Loss Programs
Programs such as Weight Watchers, Nutrisystem, and meal delivery services are generally not covered by Medicare unless they are part of a medically necessary pre-surgical weight-loss plan prescribed by a physician.
Weight-Loss Medications
Medicare Part D does not cover medications prescribed solely for weight loss, including popular drugs such as Ozempic, Wegovy, and Mounjaro, unless they are prescribed for other approved uses like managing type 2 diabetes or cardiovascular risks.
Supplemented Fasting and Very Low-Calorie Diets
These approaches are generally not covered by Medicare, except in rare cases where they are deemed medically necessary before surgery.
What Medicare Advantage (Part C) May Offer
Medicare Advantage plans offered by private insurers may include additional benefits beyond those of Original Medicare.
What’s Included?
- Fitness and wellness benefits such as gym memberships and fitness apps
- Meal delivery services for a limited time
- Extended behavioral therapy and nutrition counseling
Coverage and benefits vary significantly by plan, so beneficiaries should carefully review their options during open enrollment periods.

Looking Ahead: Possible Changes
Legislation has been proposed to allow Medicare to cover anti-obesity medications, but no changes have been approved as of now. Medicare has reaffirmed that it will not cover GLP-1 drugs under Part D when prescribed solely for weight loss.
Beneficiaries should stay informed about potential legislative updates and review their coverage options annually to ensure they are receiving the most appropriate benefits.
Tips for Beneficiaries
- Monitor your BMI to see if you qualify for covered services.
- Speak with your healthcare provider to confirm eligibility and coverage.
- Document prior weight-loss efforts, especially for surgery eligibility.
- Compare Medicare Advantage plans to find those with added wellness benefits.
- Verify any medication coverage conditions under Part D.
Original Medicare covers certain weight-loss services, including obesity screening and bariatric surgery, under specific medical conditions. It does not cover commercial weight-loss programs or medications prescribed solely for obesity. Medicare Advantage plans may offer additional wellness support. Beneficiaries are encouraged to explore their options and stay informed about potential policy changes.
