How cross-border LAMal works and why it benefits Swiss cross-border workers
Under Swiss federal law, the benefits catalog of mandatory basic health insurance (LAMal) is strictly identical across all insurers. Selecting or switching to the most competitive insurer approved by the Federal Office of Public Health (BAG/OFSP) can save up to CHF 1,200 per year with zero loss of coverage.
Annual LAMal insurer switch before 30 November
If you are already insured under cross-border LAMal and your premium increases on 1 January, you may switch to a cheaper Swiss insurer without any medical questionnaire (acceptance in basic insurance is mandatory by law), provided your cancellation letter reaches your current insurer by the last business day of November.
Dual healthcare territoriality (Switzerland + France)
In Switzerland, you are reimbursed under LAMal rules (CHF 300 deductible plus 10% co-pay capped at CHF 700/yr). In France, by registering form S1 with your local CPAM, you use your Carte Vitale under French Social Security rules.
Exemption from French CSG and CRDS on investment and rental income
Because you are affiliated with the Swiss social security system (LAMal) rather than a mandatory French scheme, you qualify for exemption from CSG/CRDS on French rental and investment income (only the 7.5% solidarity levy applies, boxes 8SH/8SI).
Coordination with supplemental frontalier health insurance
Setup of French or Swiss supplemental coverage for co-pays, specialist fees, dental, optical and private hospital rooms.

Frequently asked questions
Technical answers to your questions
If you are employed in Switzerland for at least 8 hours per week with the same employer, you are automatically covered against occupational and non-occupational accidents under your employer's UVG/LAA policy: you should therefore exclude accident cover from your LAMal policy and save 7% on your premium.
No. For insured persons residing in the European Union (France), Swiss federal law mandates a single standard deductible of CHF 300 per year for adults and CHF 0 for children.
Upon enrollment, your LAMal insurer issues two copies of form S1. We assist you in submitting them to your departmental CPAM (Haute-Savoie, Ain, Doubs, Haut-Rhin), which activates your Carte Vitale and returns a stamped copy for your Swiss insurer.
