Major insurance providers like Aetna and Cigna often cover bariatric surgery when medical criteria are met. If you are wondering what insurance companies cover weight loss surgery, the answer depends on your specific plan, employer, and medical history. Most large insurers include bariatric procedures as a covered benefit, but they require you to meet strict guidelines first.
Weight loss surgery can be life-changing, but the cost is high without insurance. Many people ask this question because they want to know if their policy will help. The good news is that most national insurers offer some level of coverage for procedures like gastric bypass, sleeve gastrectomy, and gastric banding.
This article breaks down which companies cover these surgeries, what criteria they use, and how you can get approved. We will also cover common exclusions and tips for navigating your benefits.
What Insurance Companies Cover Weight Loss Surgery
When you search for what insurance companies cover weight loss surgery, you will find that most major carriers include bariatric surgery as a covered benefit. However, coverage is never automatic. You must prove medical necessity.
Here is a list of the most common insurers that cover weight loss surgery:
- Aetna
- Cigna
- Blue Cross Blue Shield (all state plans)
- UnitedHealthcare
- Humana
- Kaiser Permanente
- Medicare (Part B)
- Medicaid (varies by state)
Each of these companies has specific requirements. Let us look at them one by one.
Aetna Coverage For Weight Loss Surgery
Aetna covers bariatric surgery for members who meet the National Institutes of Health (NIH) criteria. You generally need a body mass index (BMI) of 40 or higher, or a BMI of 35 with at least one obesity-related condition like diabetes, sleep apnea, or high blood pressure.
Aetna also requires a documented history of failed weight loss attempts. You must show that you tried supervised diet and exercise for at least six months. Some plans require a psychological evaluation before surgery.
Procedures covered by Aetna include:
- Roux-en-Y gastric bypass
- Sleeve gastrectomy
- Adjustable gastric banding
- Biliopancreatic diversion with duodenal switch (in some cases)
Check your specific plan document because employer-sponsored plans may have different rules. Aetna does not cover experimental procedures like gastric balloons in most cases.
Cigna Coverage For Bariatric Surgery
Cigna offers coverage for weight loss surgery under its medical policies. You need a BMI of 40 or more, or a BMI of 35 with serious health problems. Cigna also requires that you have tried and failed a medically supervised weight loss program for at least six months.
Cigna covers the same main procedures as Aetna. They also cover laparoscopic sleeve gastrectomy and gastric bypass. Some plans may require pre-authorization and a letter from your doctor explaining why surgery is necessary.
One thing to note: Cigna may exclude coverage if your employer chose a plan without bariatric benefits. Always call the number on your insurance card to confirm.
Blue Cross Blue Shield Coverage
Blue Cross Blue Shield (BCBS) is a network of independent companies, so coverage varies by state. Most BCBS plans cover bariatric surgery if you meet the standard BMI requirements. Some states have additional rules, like a minimum age of 18 or a maximum age of 65.
BCBS often requires a six-month supervised diet program and a psychological evaluation. They may also ask for a letter of medical necessity from your primary care doctor. Common covered procedures include gastric bypass, sleeve gastrectomy, and gastric banding.
If you have a BCBS plan, log into your online portal to check your specific benefits. Some plans exclude weight loss surgery entirely, especially if you have a grandfathered plan from before 2010.
UnitedHealthcare Coverage
UnitedHealthcare covers bariatric surgery under most employer and individual plans. Their criteria are similar: BMI of 40 or 35 with comorbidities. They also require documentation of previous weight loss attempts.
UnitedHealthcare has a specific program called “Bariatric Surgery Program” that includes pre-surgery education and post-surgery follow-up. You must complete a nutrition class and a psychological assessment before they approve the surgery.
Covered procedures include:
- Gastric bypass
- Sleeve gastrectomy
- Gastric banding
- Duodenal switch (rarely)
UnitedHealthcare does not cover gastric balloons or other non-surgical devices unless they are part of a clinical trial.
Humana Coverage
Humana covers weight loss surgery for members who meet the same BMI thresholds. They also require a six-month supervised weight loss program and a psychological evaluation. Humana is known for having clear, straightforward guidelines.
One unique thing about Humana: they may cover revision surgery if your first procedure failed or caused complications. This is not always covered by other insurers.
Check your Humana plan for specific exclusions. Some plans do not cover bariatric surgery at all, especially if you have a high-deductible health plan.
Kaiser Permanente Coverage
Kaiser Permanente offers bariatric surgery coverage to members who meet their criteria. They require a BMI of 40 or 35 with obesity-related conditions. Kaiser also has a mandatory pre-surgery education program that lasts several months.
Kaiser covers sleeve gastrectomy and gastric bypass. They do not usually cover gastric banding because it is less effective long-term. You must also attend support groups before and after surgery.
If you have Kaiser, you will need to work within their network. They have their own surgeons and hospitals, so you cannot go to an outside provider.
Medicare And Medicaid Coverage
Medicare Part B covers bariatric surgery for beneficiaries who meet specific criteria. You need a BMI of 35 or higher with at least one obesity-related condition. Medicare also requires that you have a documented history of obesity for at least five years.
Medicare covers gastric bypass and sleeve gastrectomy. They do not cover gastric banding or gastric balloons. You must get the surgery at a Medicare-approved facility.
Medicaid coverage varies by state. Some states like California and New York cover bariatric surgery, while others like Texas and Florida have limited coverage. Check with your state Medicaid office for details.
General Requirements For Insurance Approval
Most insurance companies use similar criteria to approve weight loss surgery. Here are the common requirements:
- Body Mass Index (BMI): You need a BMI of 40 or more, or a BMI of 35 with at least one serious health problem like diabetes, sleep apnea, or hypertension.
- Documented weight loss attempts: You must show that you tried to lose weight through diet, exercise, or medical programs for at least six months.
- Psychological evaluation: Many insurers require a mental health assessment to ensure you are ready for the lifestyle changes after surgery.
- Medical necessity letter: Your doctor must write a letter explaining why surgery is needed and how it will improve your health.
- Pre-authorization: You must get approval from your insurance company before scheduling the surgery. This can take several weeks.
Some insurers also require a nutrition class, a sleep study, or a cardiac evaluation. Always read your policy carefully.
How To Check If Your Insurance Covers Weight Loss Surgery
You can find out if your plan covers bariatric surgery by following these steps:
- Call the customer service number on your insurance card.
- Ask if bariatric surgery is a covered benefit under your plan.
- Ask for the specific medical policy number or document.
- Request a list of required documents for pre-authorization.
- Ask about any exclusions or limitations, such as age or BMI caps.
You can also check your insurance company’s website. Many have a “Benefits” or “Coverage” section where you can search for bariatric surgery. Some even have a tool to see if you meet the criteria.
If you have trouble getting a straight answer, ask your doctor’s office for help. They often have a dedicated insurance specialist who can verify benefits for you.
Common Reasons Insurance Denies Coverage
Even if your insurance company covers weight loss surgery, they may still deny your claim. Here are common reasons:
- Your BMI is too low or too high (some plans have a maximum BMI of 50 or 55).
- You have not completed a supervised weight loss program.
- Your medical records do not show a history of obesity-related conditions.
- You have not had a psychological evaluation.
- The procedure is considered experimental or not medically necessary.
If you get denied, you have the right to appeal. Most insurers have a formal appeal process. You can also ask your doctor to write a stronger letter of medical necessity.
Tips For Getting Approved
Getting insurance approval for weight loss surgery takes time and effort. Here are some tips to improve your chances:
- Start a food diary and exercise log now to document your weight loss attempts.
- Get regular check-ups with your doctor to record your weight and health conditions.
- Attend a bariatric surgery information session at a local hospital.
- Complete any required programs, like nutrition classes or support groups.
- Work with a bariatric surgeon who is in-network with your insurance.
Do not rush the process. Insurance companies look for consistency and commitment. If you show that you have been trying to lose weight for months, they are more likely to approve you.
What If Your Insurance Does Not Cover Weight Loss Surgery
Some plans exclude bariatric surgery entirely. This is common with grandfathered plans or plans from small employers. If your insurance does not cover it, you have options:
- Switch to a different plan during open enrollment that includes bariatric benefits.
- Look into self-pay options at a bariatric center. Some offer cash discounts or payment plans.
- Consider medical tourism, but be careful about quality and follow-up care.
- Check if your state has a mandate that requires insurers to cover obesity treatment.
Some employers offer a “rider” that adds bariatric coverage for an extra premium. Ask your HR department if this is available.
