Complementary health insurance in France (mutuelle) and your employer's plan
Why most people in France add a complementary health insurance (mutuelle) to public cover, what an employer's compulsory plan must include, when you can refuse it, how to choose individual cover, the 100% Santé offer and the free or low-cost Complémentaire santé solidaire.
- Applies to
- Everyone covered by French public health insurance. Private-sector employees are normally covered by their employer's plan; self-employed people, students, people without work and retirees choose their own cover or may qualify for the Complémentaire santé solidaire.
- Effort
- Low effort
- Time needed
- About 15 minutes to read; comparing individual offers can take an evening
- Cost
- Employer plans are at least half paid by the employer. Individual premiums vary with age, level of cover and insurer. Complémentaire santé solidaire is free below an income ceiling, or costs €8 to €30 per month per person depending on age (2026).

France's public health insurance (Assurance Maladie) reimburses a large share of medical costs, but not all of them. What remains — the patient's share, extra fees charged by some doctors, and most of the cost of glasses, dental work and hearing aids — is what a complementary health insurance (complémentaire santé, often called a mutuelle) is for.
Complementary cover is offered by mutual insurers (mutuelles), insurance companies and provident institutions. HomiStart does not rank or recommend providers. This guide explains how the system fits together as of October 2026.

What public insurance leaves you to pay
An example from Assurance Maladie's 2026 tariffs: a consultation with a sector 1 general practitioner costs €30. If you have declared a regular doctor (médecin traitant), public insurance reimburses 70 %, minus a €2 flat contribution (participation forfaitaire), so you get back €19. A complementary insurer typically covers most of the remaining patient's share (ticket modérateur).
Other costs you may face:
- Extra fees (dépassements d'honoraires) charged by sector 2 doctors above the reimbursement base; whether your complementary cover pays them depends on your contract.
- Deductibles on medicines and paramedical care (franchises médicales): €1 per box of medicine and per paramedical act, €4 per medical transport. Assurance Maladie lists an annual ceiling of €70 per person for these deductibles (October 2026); the €2 flat contributions have their own annual ceiling. Under-18s, pregnant women from the sixth month and Complémentaire santé solidaire beneficiaries are exempt.
- Glasses, dental crowns and hearing aids: public reimbursement outside the 100% Santé offers is low.
- Hospital stays: a daily hospital charge and any private-room supplements.
Your employer's compulsory plan
Private-sector employers must offer all employees a collective complementary health plan, whatever their length of service, and pay at least 50 % of the premium. The plan must at least cover:
- the full patient's share (ticket modérateur) for consultations and care reimbursed by public insurance;
- the daily hospital charge (forfait journalier hospitalier) without time limit;
- dental prosthetics and orthodontics up to 125 % of the public reimbursement base;
- glasses within set amounts (from €100 for simple correction up to €150–€200 for complex correction).
Many plans go further, and some cover your partner and children for an extra premium. Your employer gives you the plan's summary of benefits; read it to know your level of cover.
When you can refuse your employer's plan
Membership is normally compulsory, but you can ask in writing for an exemption (dispense d'adhésion) in specific cases, usually when you are hired or when the plan is introduced. Examples include:
- you are already covered by another collective plan, for example as a dependant on your spouse's company plan;
- you have individual cover when you are hired (until that contract's expiry date);
- you receive the Complémentaire santé solidaire;
- you are on a fixed-term or temporary-agency contract, or work part-time, under the conditions set by the rules and your company's plan.
Keeping cover when you leave a job
If your contract ends for a reason other than gross misconduct and you are entitled to unemployment benefit, you keep your company plan free of charge for the length of your benefit entitlement, up to 12 months (portabilité).
When that period ends, the insurer must offer you an individual continuation contract (under the loi Évin rules). You have six months to accept. Its price is capped for the first three years — the same as active employees in the first year, then at most 25 % and 50 % more — and is free after that.
Choosing individual cover
If you are not covered through an employer, compare several offers from different types of providers. Points to check:
- Responsible contract (contrat responsable): needed to benefit from the 100% Santé offers with nothing left to pay.
- Levels of cover expressed as a percentage of the public reimbursement base (for example 100 %, 150 %, 200 %) or as a fixed amount per year, especially for glasses, dental care and specialists' extra fees.
- Waiting periods before some benefits apply, annual ceilings and exclusions.
- Third-party payment (tiers payant): many insurers provide a card so you do not have to pay their share at the pharmacy or laboratory.
- Price changes with age and whether family members can be added.
The 100% Santé offers
Under 100% Santé, a selection of glasses (frames and lenses), dental crowns, bridges and dentures, and class I hearing aids is reimbursed with nothing left to pay, when combined with a responsible complementary contract or the Complémentaire santé solidaire. Ask the optician, dentist or hearing-aid professional for a 100% Santé quote alongside any other offer. For adults, glasses can generally be renewed every two years.
Complémentaire santé solidaire (C2S)
The state-funded Complémentaire santé solidaire replaces a private policy for people with low incomes. It pays the patient's share in full within public tariffs, covers the daily hospital charge, includes the 100% Santé glasses, dental and hearing offers, and you do not pay up front at the doctor's.
2026 income ceilings for a single person (annual resources):
- free up to €10,421;
- with a monthly participation up to €14,069: €8 (age 29 or under), €14 (30–49), €21 (50–59), €25 (60–69) or €30 (70 and over) per person.
You must have lived in France for three months (or work or study here). Apply online through your ameli account or with form 12504 sent to your health insurance fund. It is granted for one year and can be renewed.
Watch out
Do not cancel an individual policy before you know whether your new employer's plan covers you; there can be a gap of several weeks.
Ask for an exemption in writing and at the right time (usually on hiring). Otherwise you may have to join your employer's plan.
Be careful with unsolicited phone offers for health insurance; take time to compare and read the conditions before you sign.
Common mistakes
Assuming the carte Vitale covers everything. Without complementary cover, glasses, dental work and specialist fees can be expensive. Paying for an individual mutuelle and also your employer's compulsory plan without asking for an exemption you may be entitled to. Not checking whether a doctor is sector 1 or sector 2 before a specialist consultation. Forgetting to send your new complementary insurer your social security details, which delays reimbursements.
Tips
Ask your employer's HR department for the plan's benefits table (tableau de garanties) and the price of covering family members. Use the Assurance Maladie online directory (annuaire santé) to check a doctor's sector and fees before booking. If your income is low, check the C2S income ceilings before buying a private policy. Keep your complementary insurance card with your carte Vitale; pharmacies and laboratories often ask for both.
Frequently asked questions
Editorial answers written by our team, based on the sources below.
Is complementary health insurance compulsory?
For private-sector employees, joining the employer's plan is compulsory unless an exemption applies. For everyone else it is optional, but most people in France have one because the patient's share and extra fees can add up.
My partner does not work. Can they join my employer's plan?
Some company plans can cover family members, sometimes for an additional premium. Check your plan's conditions with HR.
I am a student. Do I need a mutuelle?
It is optional. Students with low resources may qualify for the Complémentaire santé solidaire; otherwise compare student and standard offers from several providers.
