UnitedHealthcare is the largest commercial insurer in the country, so "does UHC cover weight-loss surgery" is one of the most-asked coverage questions. The answer is yes for the standard procedures — but UHC applies the older, higher BMI thresholds and adds a facility requirement that surprises a lot of patients.
UHC generally covers these as medically necessary when criteria are met:
UHC generally does not cover the intragastric balloon (gastric balloon) and other newer or endoscopic procedures, treating them as unproven or investigational.
UnitedHealthcare uses the long-standing thresholds:
This is where UHC differs from Cigna, which has moved to a lower bar (BMI 35 alone, or 30 with a condition). If your BMI is in the 35–39 range without a qualifying condition, you may not meet UHC's threshold even though you might meet Cigna's. See how Cigna compares →
UHC wants a full pre-surgical workup on file before it approves. Expect to need:
The facility requirement is the one people miss most: even a fully-qualified patient can be denied if the surgery is scheduled at a hospital that isn't in UHC's designated network. Confirm the facility before you schedule.
| Insurer | BMI alone | BMI with a condition | Notable requirement |
|---|---|---|---|
| UnitedHealthcare | ≥40 | ≥35 | Often a designated facility + supervised program |
| Cigna | ≥35 | ≥30 | Lower BMI bar; no fixed multi-month diet |
| Aetna | ≥40 | ≥35 | Commonly 6-month supervised program |
| Anthem / Elevance | ≥40 | ≥35 | Commonly a supervised program |
| Medicare | — | ≥35 + a condition + failed medical treatment | At an approved facility |

Check my bariatric coverageYes. Sleeve gastrectomy is covered by UHC as medically necessary when you meet the criteria — generally a BMI of 40 or higher, or 35 or higher with a weight-related condition — plus a supervised weight-management program and the required nutritional and psychological evaluations. Many plans also require a designated facility.
Yes. Roux-en-Y gastric bypass is a covered procedure under UnitedHealthcare's bariatric surgery policy, subject to the same BMI thresholds, program, and evaluation requirements as the gastric sleeve.
UnitedHealthcare uses a BMI of 40 or higher on its own, or 35 or higher with a weight-related condition such as type 2 diabetes, high blood pressure, high cholesterol, or sleep apnea. That is a higher bar than Cigna, which covers surgery at a BMI of 35 alone or 30 with a condition.
In most cases yes. UnitedHealthcare generally wants a documented, medically-supervised weight-management program before surgery, along with nutritional and psychological evaluations. The exact duration is set by your specific plan, so confirm your plan's requirement.
Generally no. UHC typically treats the intragastric balloon (gastric balloon) as unproven or investigational, so it is usually not covered. A covered procedure like the sleeve or bypass is the more likely path.
The most common reasons are a BMI below the threshold without a qualifying condition, an incomplete supervised program or missing evaluations, surgery scheduled at a facility outside UHC's designated bariatric network, or an employer plan that excludes bariatric surgery entirely. Confirming the benefit and the facility up front prevents most denials.
