Supplementary health insurance in Switzerland

Direct answer
Supplementary (VVG) insurance is private law: insurers can accept, reject, or load premiums after a health check. Never cancel existing supplementary cover until new cover is confirmed in writing. Mandatory basic insurance uses franchises CHF 300–2,500 and 10% retention capped at CHF 700; supplementary policies do not replace basic cover.
Key facts
- Basic insurance is mandatory; supplementary is optional and medically underwritten.
- Switch basic insurer yearly with notice; supplementary contracts have their own terms and waiting periods.
- Federal premium discount cap CHF 1,540 applies to basic premiums only.
- Accept new supplementary policy before cancelling the old one.
- Prämienverbilligung is cantonal and income-based for basic insurance.
What supplementary covers
Basic KVG insurance covers medically necessary treatment in general ward hospitals and defined services. Supplementary modules add comfort and speed: semi-private or private room, free hospital choice, better dental cover, glasses, complementary medicine, or worldwide travel assistance.
Every benefit depends on the policy’s general terms (AVB). Marketing names differ; the contract text decides whether a procedure is paid.
Premiums are not capped like basic insurance discounts. Insurers adjust prices by age and claims experience within legal limits.
Comparison table (typical modules)
Hospital supplementary is the most common upgrade for families planning surgery. Dental modules often have waiting periods for major work.
Some contracts guarantee future upgrades without new health questions at marriage, birth, or job change—read whether yours includes such events.
| Module | Basic KVG | Supplementary VVG |
|---|---|---|
| General ward hospital | Covered | Optional upgrade |
| Free choice of hospital | Limited | Often expanded in add-on |
| Dental | Children limited | Often in separate policy |
Underwriting and switching
Insurers may reject applications or exclude pre-existing conditions. Multiple applications in a short time create medical disclosure records—answer consistently.
Basic insurance switches on a fixed annual schedule with notice to the current insurer. Supplementary policies follow their own notice periods, often longer.
Never cancel existing supplementary cover until the new insurer confirms acceptance in writing with a start date and premium.
Worked example: retiree premiums (assumed)
Assume (not a forecast) a couple at 65 pays CHF 600 per month combined for semi-private hospital supplementary on top of basic premiums. Basic might cost another CHF 800 before Prämienverbilligung. Out-of-pocket care still runs through the basic franchise up to CHF 2,500 and the CHF 700 retention cap.
Dropping supplementary to save cash exposes you to general ward only unless you reapply and pass underwriting again later.
Common mistakes
Cancelling hospital supplementary before acceptance elsewhere and needing surgery months later.
Assuming basic insurer change automatically moves supplementary—it does not.
Buying dental cover the year before major work and hitting the waiting period.
Confusing accident cover through employer with hospital room upgrade—they are different products.
FAQ
- Can I be rejected for supplementary insurance?
- Yes. Insurers assess health status. Multiple applications create a paper trail—prepare disclosures carefully.
- Does supplementary reduce my franchise?
- No. Franchises apply to mandatory basic insurance. Add-ons reimburse defined extras per their schedule.
- Is semi-private worth it in retirement?
- Depends on hospital preferences and budget. Compare premiums at older ages, not only at signup.
- Can employers pay supplementary?
- Some employers contribute; benefits are taxable as salary unless exempt by cantonal practice—confirm with payroll.

- Premium reduction (Prämienverbilligung) in SwitzerlandPrämienverbilligung lowers mandatory health insurance premiums based on income and assets; rules are set by each canton, not the federal government. Basic insurance franchises run CHF 300–2,500 with 10% retention capped at CHF 700 per year; the maximum premium discount under federal law is CHF 1,540 (KVV Art. 93). Apply in your canton of residence—approval does not transfer automatically if you move.
- Guide: Choosing a Swiss health insurance franchiseAdults in Switzerland choose a franchise of CHF 300, 500, 1,000, 1,500, 2,000 or 2,500. After the franchise, you pay 10% of further costs, up to CHF 700 per year.
- Guide: How to change health insurer in Switzerland: deadlines and stepsYou can change your Swiss basic health insurer (KVG) every year for 1 January, with no health check and no right of refusal, as long as your cancellation reaches the old insurer by the last working day of November and you have no unpaid premiums. Supplementary insurance is a separate private contract: never cancel it before the new insurer has accepted you in writing.
