Bariatric Surgery: Costs, Reimbursement, and Insurance
Obesity surgery, also known as bariatric surgery, is considered a viable solution for individuals suffering from severe obesity, especially when other treatments (diet, exercise, medication) have not yielded sufficient results.
Prices of Bariatric Procedures
Bariatric surgery includes several types of procedures, each with its own associated costs:
- Adjustable Gastric Band: Placement of a band around the stomach to reduce its size. Cost: Between €500 and €1,000.
- Sleeve Gastrectomy: Reduction of stomach size by approximately 80%. Cost: Between €500 and €3,000.
- Gastric Bypass: Alters the digestive route by bypassing part of the stomach and intestine. Cost: Between €1,000 and €4,000.
- Mini-Gastric Bypass: A simplified version of the standard bypass. Cost: Between €7,000 and €9,000.
These costs typically include preoperative consultations, surgical fees, and hospital stay. Additional costs may apply for postoperative consultations and nutritional follow-up.
Bariatric surgery costs in Paris coverage conditions

Obesity surgery may be reimbursed by the French Social Security under strict conditions:
- Body Mass Index (BMI): Equal to or greater than 40, or greater than 35 with comorbidities (e.g. diabetes, hypertension, sleep apnea).
- Failure of Conventional Treatments: Unsuccessful weight loss attempts over a 6 to 12-month period.
- Age: Recommended for adults between 18 and 60 years old (exceptions possible upon medical review).
- Rigorous Medical Follow-Up: Mandatory before and after surgery with a multidisciplinary team (nutritionist, psychologist, surgeon).
Social Security Reimbursement
When the surgery is deemed medically necessary, it is reimbursed at 100% by Social Security under the Long-Term Illness (ALD) framework. Reimbursement covers:
- Preoperative consultations (nutritionist, psychologist, surgeon).
- The surgical procedure (sleeve, bypass, or gastric band).
- Hospitalization costs (at an approved facility, without extra charges).
- Postoperative follow-up (weight loss monitoring and adjustments).
Note: Additional charges may apply in private-sector facilities or if you choose a sector 2 surgeons. These fees may be covered by supplementary health insurance (mutuelle).
Role of Supplementary Health Insurance (Mutuelle)
Having complementary health insurance is essential to reduce out-of-pocket expenses. It may cover:
- Surgeon or anesthetist fee overruns.
- Private room fees.
- Follow-up consultations (nutrition or psychology).
Before any surgery, request a detailed estimate from your surgeon and check with your insurance provider regarding coverage conditions.
Reimbursement Eligibility Process
To be eligible for reimbursement, the process includes:
- Consultations and Assessments: Full evaluation by a multidisciplinary team.
- Social Security Approval: Submission of the complete file to validate the criteria.
- Waiting Period: Between approval and surgery, depending on availability.
These steps ensure care is tailored to each patient’s specific situation.
