Does health insurance pay for the weight-loss injection?

What basic health insurance pays

A weight-loss injection means a medicine from the group of GLP-1 receptor agonists that is authorised for weight management and injected under the skin with a pre-filled pen. Whether basic health insurance pays for it is not decided by Swissmedic’s authorisation, but by the FOPH’s List of Pharmaceutical Specialties (SL). Basic health insurance only covers medicines listed there (Art. 52 para. 1 let. b of the Federal Health Insurance Act, KVG), and only as far as the limitation allows (Art. 73 KVV).

A query of the List of Pharmaceutical Specialties on 25.09.2026 shows two products with a limitation for weight management in adults. We name them because the list names them, not as a recommendation.

The same limitation applies to both. They are reimbursed for adults with a BMI of 35 or more, or with a BMI of 28 or more if there is a weight-related condition: prediabetes or type 2 diabetes, arterial hypertension (high blood pressure) or dyslipidaemia (lipid metabolism disorder). The injection must supplement a diet with a deficit of 500 kcal per day, accompanying nutritional advice and more documented physical activity, for example with a step counter. Previous or planned bariatric surgery rules out reimbursement.

For Wegovy, the SL also contains a limitation for adolescents aged 12 and over with a body weight of 60 kg or more and obesity according to international thresholds; only the paediatric and adolescent medicine centres named in the limitation may prescribe it there.

Both entries are time-limited. What applies after the expiry date is decided by the FOPH in its review; the version in force is published on spezialitaetenliste.ch. The glossary entry Medicines explains more about the system of prices and lists.

What supplementary insurance pays

If you do not meet the limitation, basic health insurance does not pay for the weight-loss injection. In the FOPH’s view, reimbursement in individual cases (Art. 71a–71b KVV) is not an option either: in its letter to the insurers of 15.05.2025, it states that outside the limitation for weight management, the major therapeutic benefit that reimbursement in an individual case requires is missing.

Some supplementary outpatient insurance policies contribute to medicines that basic health insurance does not pay for, or not for this use. Whether this applies to weight-loss medicines, and whether there are exclusions, maximum amounts or a retention fee, is set out only in the general terms and conditions of your contract. Ask in writing before starting therapy. No supplementary insurance may cover the deductible and retention fee of basic health insurance (Art. 64 para. 8 KVG).

We are building a comparison of supplementary products under Supplementary insurance. What counts are the general terms and conditions and the information from your insurer.

Conditions

In addition to BMI and accompanying measures, the limitation requires a fixed procedure. If a step is missing, the insurer may not pay.

• Cost approval: The treatment requires cost approval from the insurer after prior consultation of its medical adviser. Compliance with the diet must be documented and confirmed to the insurer. How cost approval works is explained in the guide Cost approval.
• Prescription in person: Prescription and progress checks may only take place in person, either with specialists in endocrinology/diabetology or at an obesity centre. The limitation requires proven experience: at least 100 people with obesity treated per 12 months for the specialist, at least 300 for the centre, plus nutritional advice and an interdisciplinary network.
• Checks: After 16 weeks, you must have lost at least 5 % of your starting weight with a starting BMI of 28 to under 35, and at least 7 % with a BMI of 35 or more. After a further 6 months, the total must be 10 % or 12 % respectively. Continuing requires a new cost approval, followed by checks every 6 months as a rule.
• Discontinuation: If your weight rises above the 10-month target, reimbursement ends. It also ends as soon as your BMI falls below 25; if it rises above 25 again, therapy may be resumed within the maximum duration. If you do not reach the minimum weight loss after 16 weeks the first time, you are generally excluded from later reimbursement.
• Maximum duration: In total, basic health insurance pays for a maximum of 3 years, even if you switch between products.
• No combination: The injection may not be combined with other GLP-1 receptor agonists or other weight-loss medicines.
• Co-payment: If the insurer pays, the normal co-payment applies: first the deductible, then a 10 % retention fee up to CHF 700 a year for adults (Art. 64 para. 2 KVG, Art. 103 KVV).

Behind these requirements is the law: basic health insurance only covers services that are effective, appropriate and cost-effective (Art. 32 para. 1 KVG). With the limitation, the FOPH sets out for which people it considers these criteria to be met.

Sample calculation

Example with fictitious people and assumed costs. Daniel is 45, 1.75 m tall and weighs 110 kg. His BMI is 110 ÷ (1.75 × 1.75) = 35.9. He meets the weight threshold without a related condition. The insurer gives cost approval. Daniel has a CHF 300 deductible and no other medical costs in the year. We assume medicine costs of CHF 2,400 in the first year and CHF 1,200 for medical and advice appointments; both are calculation values. Deductible, retention fee and maximum amount come from Art. 64 KVG and Art. 103 KVV.

If you are planning therapy over several months, you will usually reach your deductible in the same year. Whether a lower deductible is then cheaper, you can work out in the deductible calculator; your insurer must receive a switch to a lower deductible by 30 November, see Deadlines.

How to proceed

1. Ask your GP: They clarify with you whether you could meet the requirements of the limitation and refer you to a specialised centre.
2. Start the accompanying measures: Nutritional advice and the documented diet are part of the conditions, not an extra.
3. Wait for cost approval: The specialised centre submits the request. Only start once you have the insurer’s written approval.
4. Keep your check-up appointments: The evidence after 16 weeks and 10 months decides whether therapy continues.
5. Ask your supplementary insurer in writing: Asking for a contribution is only worthwhile if you do not meet the limitation and have supplementary insurance.

Common mistakes

• Starting therapy before cost approval. Without approval, the insurer can refuse to pay the costs.
• Ordering online and submitting the invoice. Online prescriptions do not meet the limitation.
• Expecting a diabetes product for weight loss. Basic health insurance does not pay for products with a limitation for diabetes only when they are used for weight management.
• Thinking the 3 years apply per product. The maximum duration applies to all products together.
