RSI ( Régime Sociale des indépendants )
French Social Security for self-employed workers.
NB. RSI in France is the administrative umbrella and will not reimburse medical treatment.
Reimbursements come from a third-party called “Régime Obligatoire” (R.O.) that you must choose upon registration of your activity.
When choosing your RO. bear in mind that some of the smaller or local ones
do not have the “TELETRANSMITION” facility with the Top-Ups.
This will not alter your rights but you will have to send off paperwork to get reimbursed.
