Insurance requirements for a gastric sleeve: how insurers decide

Insurers decide on a gastric sleeve in two steps. First, does your particular plan include bariatric surgery at all. Second, do your records meet the plan's written medical policy: a body mass index (BMI) threshold, related health conditions, and a documented evaluation. Policies differ between insurers and change over time, so the published ones below are examples, not a promise of how your plan will rule.

Step one: is bariatric surgery a covered benefit in your plan

A medical policy only applies if your plan covers the service. Aetna's policy states that most Aetna HMO and QPOS plans exclude coverage of obesity surgery unless approved by Aetna, and that some Aetna plans entirely exclude it. Cigna's says coverage for bariatric surgery varies across plans and may be governed by state mandates, and that the customer's own benefit plan document always overrides the policy.

So the first question for your insurer is simple: "Does my plan cover bariatric surgery, and is sleeve gastrectomy included?" Ask for the answer in writing or note the date, the name of the person and the reference number of the call. Employer plans that are self-funded can set their own rules, which is why two people with the same insurer's card can get different answers.

Step two: the medical criteria, with published examples

The table summarizes what three published policies ask of an adult. It is a plain-language summary; the wording in the policies themselves controls.

Policy	BMI and health conditions	Evaluation and program
Aetna Clinical Policy Bulletin 0157	BMI of 40 or more, or 35 or more with at least one listed condition: clinically significant obstructive sleep apnea, coronary heart disease, medically refractory hypertension, type 2 diabetes, or MASH (a form of fatty liver disease). Lower thresholds are listed for people of Asian ancestry.	A past attempt at weight loss without long-term success; an intensive multicomponent behavioral program of 12 or more sessions within the 2 years before surgery; assessment by a behavioral health clinician.
Cigna Coverage Policy 0051	BMI of 35 or more, or 30 to 34.9 with at least one clinically significant obesity-related condition (the policy lists diabetes, sleep apnea, poorly controlled hypertension, fatty liver disease and others). Lower thresholds are listed for Asian patients.	A multidisciplinary evaluation within the previous 12 months that includes a description of the planned procedure, documentation of failure of weight loss by medical management, clearance by a mental health provider, and a nutritional evaluation.
Medicare National Coverage Determination 100.1	BMI of 35 or more with at least one obesity-related condition.	Previously unsuccessful medical treatment for obesity. For a stand-alone laparoscopic sleeve, the regional Medicare contractor may determine coverage.

Both commercial policies list sleeve gastrectomy among the procedures they consider medically necessary when the criteria are met. Medicare's rules have their own page: see Medicare and bariatric care. For Medi-Cal managed care, see IEHP, Medi-Cal and bariatric surgery.

Why insurer rules and medical guidelines do not always match

The 2022 ASMBS/IFSO guidelines recommend metabolic and bariatric surgery for people with a BMI of 35 or more regardless of other conditions, and say it should be considered at a BMI of 30 to 34.9 with metabolic disease. They update criteria that dated from 1991.

Insurers adopt new guidelines at different speeds. In the examples above, Cigna's current policy follows the newer thresholds, while Aetna's and Medicare's still require a related condition at a BMI of 35 to 39.9. If your BMI is between 30 and 35, our page on a gastric sleeve with a BMI of 30 to 35 covers that situation in detail.

Some plans also require a set number of months of supervised weight management before surgery. The 2022 ASMBS/IFSO guidelines state that there are no data to support insurance-mandated preoperative weight loss. A plan can still require it, and if yours does, the visits have to be completed and documented. This is different from the short diet a surgeon may ask for just before the operation, explained in the pre-surgery liver diet.

The records insurers usually look for

Height, weight and BMI recorded by a clinician, often over more than one visit
Related conditions with supporting results, such as a sleep study, blood sugar tests or blood pressure records
Weight history, including earlier attempts with diet, exercise programs or medication
Nutrition evaluation by a dietitian or other qualified clinician
Behavioral health evaluation
The surgeon's consultation note naming the planned procedure and why

Many of these overlap with the medical work-up described in tests before gastric sleeve surgery, so one set of appointments may serve both purposes. Practices differ on which evaluations they arrange and which they refer out, so ask the office how this works.

Prior authorization, and what to do after a denial

Prior authorization means the insurer reviews the request and approves it before surgery is scheduled. A surgeon's office commonly sends the request with the records above; ask the office who submits it in your case. Do not book time off work around a surgery date until the approval is in hand.

If the request is denied, the denial letter should state the reason and explain how to appeal. Reasons can include a missing document, a program that was not completed, or a plan exclusion. A missing document can often be supplied, and a program can often be finished. An exclusion is a benefit question for your employer or plan, not a medical one. Keep the letter, and ask your surgeon's office about it before deciding what to do next.

Frequently asked questions

Does my BMI at the first visit or on the day of surgery count?

It depends on the policy, so ask your insurer which measurement it uses. Aetna's policy, for example, refers to BMI measured before the preoperative preparatory program, and it asks for persistent severe obesity documented in clinical records. Other policies may not spell this out, so get the answer before you start any pre-surgery weight loss.

Will my insurer accept a weight-loss program I did last year?

It depends on the policy's time window. Aetna's policy, for example, counts an intensive behavioral program of 12 or more sessions completed within the 2 years before surgery, and Cigna's asks for a multidisciplinary evaluation within the previous 12 months. Bring records of any program you completed, and ask your insurer whether it falls inside the plan's window.

Is a psychological evaluation always required for a sleeve?

Not by every plan, but it is common. Cigna's policy asks for clearance by a mental health provider. Aetna's asks for an assessment by a qualified behavioral health clinician covering psychosocial functioning, substance use and eating behaviors, with referral and treatment for any issues found. Ask your insurer whether it must be done by an in-network clinician.

What if my employer's plan excludes weight-loss surgery?

Then meeting the medical criteria does not create coverage. Your choices are to ask your employer's benefits office whether another plan option includes bariatric surgery at the next enrollment period, to check a spouse's plan, or to consider paying yourself. Our page on what affects the cost of a gastric sleeve explains what goes into a self-pay estimate.
