If you wish to choose between Swiss and French health insurance (Droit d'option), you must do it within three months after :

- starting your job in Switzerland ;
- moving to France.

If you do not choose by yourself after 3 months, you’ll be attached to Swiss health insurance.

Once your choice is done, you can not change it.

A new opportunity to make this choice will be possible if you start a job in Switzerland after a period of unemployment or if you are a new beneficiary of a swiss pension.

If you choose the french health insurance, you must fill in the form « Choix du système d'assurance maladie (PDF) », attach the requested documents and send your application to your local CPAM.

You can find your CPAM details in the section « Addresses and contacts » on ameli.fr website.

Once your CPAM confirmed you are entitled in the french system by returning your form approved, you will have to forward it to your swiss institution.

To know more about the contribution, please contact « centre national des travailleurs frontaliers suisses » (CNTFS) from Urssaf.

If you choose the swiss health insurance, you must fill in the same form, attach a copy of your S1 delivered by Switzerland and send your file to your CPAM for it to be stamped.

You then have three months to return this document to the swiss health insurance.
