## Quick answer TRICARE covers bariatric surgery (such as gastric bypass or sleeve gastrectomy) when it is medically necessary to treat morbid obesity and its associated health risks. To qualify, you must meet specific Body Mass Index (BMI) thresholds and demonstrate that previous non-surgical weight loss attempts have failed.
Details
TRICARE coverage for weight loss surgery is strict and requires prior authorization. It is not covered for "cosmetic" reasons or simple weight loss without underlying medical complications.
### Qualifying Criteria (2026 Guidelines) To be eligible for coverage, a beneficiary must meet one of the following two criteria: 1. **BMI of 40 or higher:** You must have a Body Mass Index of 40 or greater. 2. **BMI of 35–39.9 with Co-morbidities:** You may qualify with a lower BMI if you have a high-risk condition such as life-threatening type 2 diabetes, severe obstructive sleep apnea, or cardiovascular disease that has not responded to other treatments.
Additionally, the patient must be at least 18 years old (or have reached skeletal maturity) and have failed a physician-supervised program of exercise and diet before surgery will be approved.
### Covered Procedures As of 2026, TRICARE typically covers the following procedures if criteria are met: * **Roux-en-Y Gastric Bypass (RYGB)** * **Vertical Sleeve Gastrectomy (VSG)** * **Adjustable Gastric Banding (LAP-BAND)** * **Biliopancreatic Diversion with Duodenal Switch (BPD/DS)**
### Procedures NOT Covered TRICARE explicitly excludes several procedures, including: * Nonsurgical procedures (like intragastric balloons). * Experimental or unproven weight loss surgeries. * Revisions of previous surgeries solely for more weight loss (revisions are only covered if the original surgery had a medical complication).
### Costs and Plan Types Costs for bariatric surgery vary significantly by plan and status: * **Active Duty:** $0 out-of-pocket, but must receive surgery at a Military Medical Center or have a specific referral to a civilian provider. * **TRICARE Prime:** Retirees and family members usually pay a small copayment if using an in-network provider ($0 for active duty families). * **TRICARE Select:** Group A and Group B beneficiaries will owe a deductible and a percentage of the allowed amount (cost-share). For 2026, check your specific Select enrollment group for the exact percentage.
## Who this affects * **Active Duty Service Members:** Requires a referral and fitness-for-duty evaluation. * **Active Duty Family Members:** Covered under Prime or Select. * **Retirees and their Families:** Covered, though cost-shares apply. * **TRICARE Reserve Select (TRS) / TRICARE Retired Reserve (TRR):** Covered following the same medical necessity rules as TRICARE Select.
