Key takeaways:
Weight-loss surgery can cost thousands of dollars without insurance. But insurance may cover it if a healthcare professional deems it medically necessary.
Insurance coverage for weight-loss surgery often requires meeting certain criteria. These include a high body mass index, obesity-related conditions, or documented weight-loss attempts.
Insurance may not cover weight-loss surgery if it’s considered cosmetic. An out-of-network healthcare professional also may not be covered.
Bariatric surgery is one of the most effective ways to achieve lasting weight loss. After surgery, people lose up to 60% of excess weight within 6 months and 77% within a year.
For many, insurance can help cover the cost—but approval isn’t guaranteed. Coverage depends on your plan and the type of procedure. Also, a healthcare professional may need to classify it as medically necessary. Meeting your insurer’s eligibility criteria is key.
Many insurance companies acknowledge the significant health risks associated with excess weight. That’s why they provide coverage for weight-loss surgery when qualifications are met. Coverage varies depending on your plan.
Bariatric surgery is part of the Affordable Care Act’s essential health benefits. Individual and small-group insurance plans in 23 states must include coverage. But what if you live in a state without this mandate or you’re part of a large-group insurance plan? Your coverage depends on whether your insurer or employer includes bariatric surgery.
Medicare covers certain weight-loss surgeries. These include laparoscopic sleeve gastrectomy and laparoscopic adjustable gastric banding. But you must meet Medicare’s criteria for morbid obesity and try other treatments first.
Medicaid coverage for weight-loss surgery and eligibility rules vary by state. For example, Colorado calls for a mental health evaluation. Illinois requires participation in a weight-loss program. Medicaid may also cover only certain weight-loss procedures depending on your state. Review your plan, or visit your state’s Medicaid website to learn more about your benefits.
Tricare covers several bariatric surgical procedures. These include Roux-en-Y gastric bypass, sleeve gastrectomy, and adjustable gastric banding. But you must meet certain Tricare requirements. This includes being at least 18 years old. Also, your medical records need to show past weight-loss attempts that didn’t work. The surgery must be considered medically necessary.
Veterans may qualify for weight-loss surgery through their Veterans Affairs (VA) benefits. But they must meet specific eligibility criteria.
Veterans must complete a comprehensive presurgical evaluation. This may include a mental health assessment and medical tests. Having medical conditions that may risk complications from surgery could disqualify you. Veterans must also make prior attempts to lose weight through diet and exercise.
Does insurance cover weight-loss medications? Coverage varies by plan, but here are a few things to consider if you take Wegovy or another GLP-1 medication.
Medicare coverage for weight-loss surgery: Medicare covers certain bariatric surgeries if you meet the requirements.
A healthcare professional may prescribe medications after weight-loss surgery. There are many ways to save money on prescription medications, including using a GoodRx coupon.
If your insurance covers weight-loss surgery, you must meet the requirements. Ask a healthcare professional about your plan’s criteria before making an appointment.
Common weight-loss surgery requirements include the following:
Be age 18 or older
Have a body mass index (BMI) over 40 or a BMI over 35 with Type 2 diabetes, high blood pressure, or other risk factors
Undergo psychological testing
Complete smoking cessation before surgery
Have made weight-loss efforts in the past
No current substance use disorder
Have a morbid obesity diagnosis for a period before surgery
Finish an insurance-mandated weight-loss program
Many insurance plans cover bariatric surgery. But there are several reasons your procedure might be denied. Insurance is unlikely to cover weight-loss surgery in the following cases:
Insurers may need proof that weight-loss surgery is necessary to treat a serious medical condition. Examples include obesity-related diabetes, hypertension, and sleep apnea. Your case must meet their definition of medically necessary. If it doesn’t, coverage may be denied.
Some plans cover only specific weight-loss procedures, like gastric bypass or sleeve gastrectomy. Others, such as gastric ballooning or open adjustable gastric banding, may be excluded.
Insurance companies typically have BMI requirements for bariatric surgery. A BMI over 40 or a BMI over 35 with obesity-related health conditions is often needed. An insurer may also request a documented history of supervised weight-loss attempts. This includes diet and exercise programs.
Many insurers require a physician-supervised weight-loss program before approving bariatric surgery. Participation requirements typically range from 6 to 12 consecutive months, depending on the insurer’s specific guidelines. Missing medical records or incomplete paperwork may lead to a denial.
Some insurance plans cover weight-loss surgery only if you use in-network professionals. This means your surgeon and hospital must be in their approved network. If you choose an out-of-network professional, you may be responsible for the full cost.
Certain health plans, including some employer-sponsored and Medicaid programs, exclude bariatric surgery entirely. Always check your policy’s coverage details before starting the process.
Your insurance may cover only certain types of weight-loss surgery. For example, Medicare doesn’t cover laparoscopic sleeve gastrectomy. Check your plan to find out which types of bariatric surgeries are covered.
Weight-loss surgery typically costs $7,000 to $33,000 before insurance. Your cost will depend on several factors. These include the procedure you choose and your location.
Insurers generally cover body contouring after significant weight loss from bariatric surgery. People with issues that affect their daily activities may also be covered.
Weight-loss programs covered by insurance vary by provider. For example, Aetna’s coverage excludes WeightWatchers and similar programs. But Independence Blue Cross offers reimbursement for approved weight-management programs. Check your plan for details.
Medicare does not cover nonsurgical weight-loss programs. That includes commercial weight-loss plans and fitness programs. But weight-management programs that are medically necessary to treat obesity may be covered. Some Medicare Advantage plans cover gym memberships or fitness programs, such as SilverSneakers and Silver&Fit.
Medicaid may cover certain nonsurgical weight-loss treatments. Examples include medical nutrition therapy and obesity counseling. Coverage varies by state. These treatments are often provided under a healthcare professional’s supervision. These services may be covered if they are part of a treatment plan for obesity or a related health condition.
Tricare typically doesn’t cover commercial weight-loss programs. But it may cover medically supervised weight-loss treatments. This can include medical nutrition therapy or counseling.
The VA offers a free weight-management program for veterans called MOVE! This program provides classes on nutrition, physical activity, and behavior change. Veterans ages 70 and older or those with a BMI of 25 to 30 are eligible to enroll.
Many insurance plans cover weight-loss surgery. But it must be medically necessary and not for cosmetic reasons. Your plan may cover only certain procedures, and you must meet its rules to qualify. Coverage for weight-loss programs also depends on the treatment and your specific policy.
