How do you get LAMal health insurance when you settle in Switzerland?
In Switzerland, everyone domiciled there must take out insurance for healthcare with a Swiss health insurer (caisse-maladie): this is the compulsory healthcare insurance provided for by the health insurance act (LAMal). You have 3 months after taking up domicile to affiliate (art. 3 LAMal); if you meet this deadline, the insurance takes effect on the day of your arrival. After that deadline, it only starts on the date of affiliation, and a premium surcharge may be billed to you.
- Costs
- Premiums vary by insurer, canton and deductible (official comparison tool priminfo.ch)
- Timeframes
- Affiliation within 3 months of taking up domicile, with retroactive effect
Steps
- Before leaving: take your European Health Insurance Card (EHIC) for unforeseen care in the first weeks. It does not replace the LAMal once you are domiciled in Switzerland.
- Register with your commune (sheet CH-SEJOUR-TOUS-001).
- Compare health insurers and choose your deductible (franchise): premiums vary by insurer, canton and deductible. The official site priminfo.ch lets you compare.
- Affiliate within 3 months of taking up domicile (or of a child's birth). The insurance then takes effect on your arrival date. If you work in Switzerland without living there (like a cross-border worker), it takes effect at the start of your activity.
- Insure your family too: each person domiciled in Switzerland must have their own insurance, children included (their parents insure them). For a cross-border worker, the obligation extends to family members without gainful activity: spouse, children under 18 and dependent adult children.
- If you think you may be exempt (for example a posted worker, or cases provided for certain cross-border workers), apply to the canton, or to the Institution commune LAMal in the cantons where it handles this (online application, decision announced within 3 working days).
Documents
- ID and proof of your domicile in Switzerland (residence permit or certificate from the commune); each insurer sets its own list of documents and gives it to you with the membership application.
- For an exemption application: proof of your cover abroad (posting forms, insurance certificates).
Costs and timelines
- Deadline: 3 months after taking up domicile (or birth in Switzerland), set by article 3, paragraph 1, of the LAMal; with retroactive effect if you meet it.
- Late affiliation: the insurance only starts on the date of affiliation; premium surcharge in the case of inexcusable delay.
- Premiums: vary by insurer, canton and chosen deductible; official comparison tool: priminfo.ch.
- Your AVS number appears on your health insurance card (sheet CH-NIF-TOUS-001).
Common pitfalls
- Letting the 3 months go by. You lose the retroactive effect and risk a premium surcharge. It is the canton that monitors the obligation.
- Thinking that registering with the commune is enough to fix your domicile. For the LAMal, domicile is the place where you live with the intention of settling there; communal registration is not the only criterion.
- Without gainful activity: to obtain your residence permit, you also need health and accident insurance covering all risks (SEM).
- Counting on the EHIC. It covers necessary care during a temporary stay, not a move, nor private care, nor repatriation.
What changes by country of origin
- EU and EFTA citizens: obligation within 3 months. The law also allows the Federal Council to extend the obligation to non-domiciled people who habitually work or stay in Switzerland, such as certain cross-border workers (art. 3, para. 3, LAMal). Switzerland applies European coordination: EHIC for temporary stays, and European forms (for example for posted workers) that can justify an exemption.
- Swiss citizens: not applicable (sheet for people coming to settle).
- British citizens (Scots included): the same obligation as soon as they are domiciled in Switzerland. The Institution commune LAMal mentions the United Kingdom together with the EU for cross-border workers and retirees (retirees living in the United Kingdom and receiving a Swiss pension, for example). The British GHIC card is for temporary stays.
