8 min read 1. Is the right of option really irrevocable?
Yes, in principle. The health insurance choice made during the first three months of cross-border employment in Switzerland is definitive, and you cannot switch from LAMal to a national system (or vice versa) simply to reduce your monthly costs or because premiums rise.
Under the bilateral agreements between Switzerland and its neighbours, every cross-border worker must exercise their "right of option" within 3 months of their first job in Switzerland. Once made and validated by the authorities, this choice binds you for the entire duration of your cross-border activity. It is a stability rule intended by both states: it prevents insured persons from moving between systems depending on their health or the evolution of premiums.
However, certain major life events essentially reset a worker's administrative status. These "changes of situation" grant a new, strict 3-month (90-day) window to exercise a new right of option. Outside these exhaustively listed cases, no switch is possible. To understand the underlying difference between the systems before reopening your choice, read our comparison guide on cross-border worker health insurance: LAMal or your national system.
2. Which situations reopen the right of option (France, Germany, Italy)?
Three changes of situation, and only these three, reopen the right of option: resuming Swiss work after unemployment in your country of residence, moving from Switzerland to a neighbouring country, and retiring on an exclusively Swiss pension. Each one opens a 3-month window.
A. Resuming employment after a period of unemployment
If a cross-border worker loses their job in Switzerland, they fall under the unemployment system of their country of residence: Pôle Emploi / France Travail in France, the Agentur für Arbeit in Germany, or INPS (NASpI) in Italy. During this period of subsidized unemployment, the individual is compulsorily affiliated with their national social security system. Upon signing a new employment contract in Switzerland, this is legally considered a "new start of activity", which reopens the right of option. To anticipate the full unemployment-to-rehire sequence, see our guide on dismissal and unemployment in Switzerland.
B. Moving from Switzerland to a neighbouring country
An expatriate (B permit holder) who is compulsorily affiliated with LAMal and decides to relocate to a neighbouring country — for example moving from Geneva to Annemasse, Zurich to Konstanz, or Lugano to Como — experiences a change in legal status, becoming a cross-border worker (G permit). This relocation grants them the right to choose between keeping a LAMal cross-border policy or joining their national system (CMU, GKV or SSN).
C. Transitioning to retirement
The liquidation of pension assets modifies a worker's social security allegiance. If the former cross-border worker receives exclusively a Swiss pension (and no pension from their country of residence), they are granted a new right of option to determine their healthcare coverage as a retiree. Note that receiving even a single national pension generally closes this possibility, as it ties you to your national system.
Simply changing employers in Switzerland (with no interruption or unemployment), changing your working hours (part-time to full-time), marriage or the birth of a child do not allow you to change your own insurance choice. Marriage and birth only serve to determine the affiliation of dependents (a spouse without income, children).
3. How do you actually change your health insurance?
As soon as the change of situation takes effect, the 3-month countdown begins (the start date of the new contract or the official moving date). The procedure has three steps, with an exemption form that must be stamped by your chosen insurer and validated by the canton.
You must acquire the official form to request an exemption from compulsory Swiss health insurance. This form is specific to your canton of employment (for example SAM in Geneva, OVAM in Vaud, SVA in Zurich).
Step 2 — Register with the chosen system:
- If choosing the national system (France: CMU, Germany: GKV/PKV, Italy: SSN): register with your local health authority — CPAM in France, a German Krankenkasse (AOK, TK, Barmer), or an Italian ASL/ATS. This authority must stamp and sign the Swiss form to certify that your coverage meets the equivalent standards.
- If choosing the Swiss system (LAMal): take out a basic cross-border insurance policy with a Swiss provider (e.g. Helsana, Swica). They will issue an S1 form, which you submit to your local health authority so that your medical costs are covered in your country of residence.
Step 3 — Cantonal validation: the fully completed and stamped dossier must be submitted to the relevant Swiss cantonal authority within the 3-month deadline for final validation. It is this authority that definitively confirms your exemption or your affiliation.
If you do not submit the validated form within 3 months of your change of situation, the Swiss authorities automatically affiliate you with LAMal — and this default decision is irrevocable. Never treat this deadline lightly.
If you stay with LAMal, check how your care is covered in your country of residence through the S1 form, explained in our guide on what LAMal covers abroad (S1 form).
4. How do you pay Euro premiums without losing on exchange?
Changing insurance has a direct impact on your cross-border cash flow, because premiums and contributions are not paid in the same currency as your salary. Optimising the exchange rate on each transfer prevents the cost of your cover from being artificially inflated.
- Paying in euros: if you opt for the French CMU, the German GKV/PKV or voluntary SSN contributions in Italy, you must pay these in euros. Your salary, however, is paid in Swiss francs (CHF), so a currency transfer is required.
- The cost of traditional banking: transferring CHF to EUR via traditional banks subjects you to hidden exchange-rate margins (often 1.5% to 3%) and transfer fees, artificially inflating the cost of your healthcare.
To pay a national premium of 300 EUR, ibani converts the exact amount from your Swiss salary account at the real interbank market rate (reference rate around 0.921), with no hidden fees. Where a bank applying a 2% margin would cost you the equivalent of roughly 6 EUR extra every month, you keep your full purchasing power. Over a year of premiums, the saving becomes significant.

💡 The ibani solution: convert your Swiss francs to euros at the real rate, with no hidden margin, to pay your CMU, GKV or SSN contributions without losing on exchange.
