Medicare does cover some weight loss programs and services, but only the medical ones: free behavioral counseling for obesity, bariatric surgery for people who meet strict criteria, and, starting July 2026, GLP-1 medications like Wegovy and Zepbound at a $50 monthly copay through a new short-term program. It does not pay for commercial diet plans, gym memberships, or over-the-counter supplements.
What Medicare Won’t Pay For
Before the covered benefits, it helps to know the boundaries. Original Medicare does not reimburse Weight Watchers, Noom, Jenny Craig, or similar commercial programs. It does not cover gym memberships (though some Medicare Advantage plans do, discussed below). It does not cover meal replacement shakes or weight-loss supplements. And Part D has long been barred by statute from covering drugs used solely for weight loss, a rule traceable to the Social Security Act.1HHS.gov. Medicare Coverage of Anti-Obesity Medications That last rule is being worked around in 2026, but the underlying prohibition still shapes what your Part D plan will and won’t pay for.
Behavioral Counseling for Obesity
The most accessible weight loss benefit is Intensive Behavioral Therapy (IBT) for obesity, covered under Part B as a preventive service. Your BMI must be 30 or higher to qualify, and the counseling has to be delivered by your primary care doctor, nurse practitioner, or physician assistant in a primary care setting.2Medicare.gov. Obesity Behavioral Therapy
Each visit includes a dietary assessment and counseling on diet and exercise. CMS sets the schedule:
- Month 1: one face-to-face visit per week (four sessions).
- Months 2 through 6: one visit every other week (about ten sessions).
- Months 7 through 12: one visit per month, but only if you’ve lost at least 3 kilograms (about 6.6 pounds) in the first six months.
That weight-loss check at six months is a real gate. If you haven’t lost the 3 kilograms, the monthly sessions in the second half of the year aren’t covered. Your doctor reassesses your readiness after another six months, and you can restart the program then.3Centers for Medicare & Medicaid Services. NCA – Intensive Behavioral Therapy for Obesity (CAG-00423N) – Decision Memo
Because IBT is preventive, you pay nothing when your provider accepts Medicare assignment. No deductible, no coinsurance.2Medicare.gov. Obesity Behavioral Therapy
Bariatric Surgery
Medicare covers weight loss surgery for people with severe obesity, but the eligibility bar is higher than for counseling. You must meet all three requirements:
- BMI of 35 or higher.
- At least one obesity-related health condition, such as type 2 diabetes, heart disease, or sleep apnea.
- A documented history of unsuccessful medical weight loss treatment.
The procedures with national coverage are Roux-en-Y gastric bypass (open or laparoscopic) and laparoscopic adjustable gastric banding. Sleeve gastrectomy is decided at the regional level by local Medicare Administrative Contractors, so whether it’s covered depends on where you live.4Centers for Medicare & Medicaid Services. NCD – Bariatric Surgery for Treatment of Co-Morbid Conditions Related to Morbid Obesity 100.1
The surgery involves Part A cost sharing for the hospital stay and Part B cost sharing for the surgeon’s services. For 2026, the Part A inpatient deductible is $1,736 and the Part B annual deductible is $283, with 20% coinsurance on the Medicare-approved amount after that.5Centers for Medicare & Medicaid Services. 2026 Medicare Parts A and B Premiums and Deductibles6Centers for Medicare & Medicaid Services. MM14279 – Medicare Deductible, Coinsurance and Premium Rates CY 2026 Update Medicare Advantage plans may use copays or different structures, so check your plan’s Summary of Benefits.
GLP-1 Drugs: Wegovy, Zepbound, and Ozempic
Coverage of GLP-1 medications through Medicare has been narrow and is about to widen. Ozempic and other GLP-1s approved for type 2 diabetes are covered by Part D for that condition. In March 2024, the FDA approved Wegovy to reduce the risk of heart attacks and strokes in people with established cardiovascular disease who also have obesity or are overweight, which lets Part D plans cover Wegovy for beneficiaries who meet that combined profile.1HHS.gov. Medicare Coverage of Anti-Obesity Medications What Part D still cannot do is cover a GLP-1 purely for weight loss.
The Medicare GLP-1 Bridge Starting July 2026
In December 2025, CMS announced a short-term demonstration called the Medicare GLP-1 Bridge, running from July 1 through December 31, 2026. This program covers Wegovy (injection and tablets) and Zepbound specifically for weight reduction, and it sits outside the regular Part D benefit.
To qualify, you need to be enrolled in a standalone Part D plan or a Medicare Advantage plan with drug coverage in 2026. A central CMS processor handles prior authorization and claims, not your plan. Your cost is a flat $50 copay per monthly supply regardless of which Part D benefit phase you’re in. Participating manufacturers agreed to a net price of $245 per month. One catch: neither the drug cost nor your copay counts toward your Part D out-of-pocket spending or catastrophic threshold.7Centers for Medicare & Medicaid Services. Medicare GLP-1 Bridge
The Bridge is designed to hand off to a longer-term program called the BALANCE Model. If you start on a GLP-1 through the Bridge in 2026, you’ll need to enroll in a BALANCE-participating Part D plan for 2027 to keep access.7Centers for Medicare & Medicaid Services. Medicare GLP-1 Bridge
Medical Nutrition Therapy for Diabetes and Kidney Disease
If your weight concerns overlap with diabetes or kidney disease, Part B also covers Medical Nutrition Therapy (MNT). It’s separate from IBT and provides nutritional assessments and counseling from a registered dietitian or nutrition professional. You need a physician referral. Session limits apply per calendar year, but your doctor can request additional hours if your diagnosis, condition, or treatment plan changes.8eCFR. 42 CFR 410.132 – Medical Nutrition Therapy
Medicare Advantage Fitness and Wellness Benefits
Medicare Advantage plans must cover everything Original Medicare covers, including IBT and bariatric surgery under the same rules.9Medicare. What Part B Covers Many go further with supplemental benefits Original Medicare doesn’t offer. Fitness memberships like SilverSneakers are common, giving access to participating gyms, group classes, online workouts, and at-home exercise kits at no extra cost. Some plans include quarterly over-the-counter allowances, though weight-loss supplements and meal replacement shakes are usually excluded as “dual-purpose” items.
These extras vary a lot between plans. If weight management support matters to you, compare the fitness and wellness benefits during open enrollment rather than assuming every Advantage plan includes them.
How to Get Started
For behavioral counseling, book a visit with your primary care doctor. They’ll check your BMI, and if it’s 30 or above, they can begin IBT sessions in their office. No separate referral is needed. For bariatric surgery, your doctor documents your BMI, related conditions, and prior weight loss efforts before referring you to a surgeon; confirm Medicare participation with the surgeon’s office before scheduling. For the GLP-1 Bridge, watch for CMS guidance closer to July 2026 on how to access the program through the central processor, since your Part D plan won’t manage those claims directly.7Centers for Medicare & Medicaid Services.
