Health Insurance: The Complete Guide

The French Healthcare System and the Role of Health Insurance

The French healthcare system is based on a principle of national solidarity managed by Health Insurance (Social Security). However, Social Security doesn't reimburse all healthcare costs. This is where complementary health insurance, commonly called "mutuelle," comes in. Visit our insurance section for more coverage guides.

Complementary health insurance covers all or part of costs remaining after Social Security reimbursement: the "ticket moderateur" (co-payment), excess fees, certain care not reimbursed by Social Security, etc.

Complementary Health Insurance Providers

In France, three types of organizations can offer complementary health insurance:

Mutuelles: These are non-profit organizations governed by the Mutuality Code. Historically, they're often linked to professions or business sectors.

Provident institutions: Also non-profit, they're jointly managed by employers and employees and mainly offer collective contracts.

Insurance companies: These are for-profit commercial companies, subject to the Insurance Code.

In common usage, the term "mutuelle" is often used to describe any complementary health insurance, regardless of the type of organization offering it.

Legal Obligations

Mandatory Company Health Insurance

Since January 1, 2016, all private sector employers must offer collective health insurance to their employees. This obligation stems from the National Interprofessional Agreement (ANI) of 2013 and the Employment Security Law.

Scheme characteristics:

The employer must finance at least 50% of the premium
The contract must meet a "minimum care basket" defined by law
The employee must join, except in cases of exemption provided by law
Dependents (spouse, children) may be covered according to contract terms

Exemption cases: An employee may refuse to join company health insurance in certain cases: if already covered by their spouse's insurance, if benefiting from Complementary Solidarity Health Insurance (CSS), if on a short fixed-term contract, etc.

Responsible Contract

To benefit from tax and social advantages, complementary health insurance must follow certain rules defined by the "responsible contract specifications." These contracts:

Cover the ticket moderateur on consultations and procedures within the coordinated care pathway
Limit reimbursements of excess fees
Regulate optical reimbursements
Respect 100% Sante for optical, audiology, and dental

Understanding Coverage and Reimbursements

How Reimbursements Work

Reimbursement of your healthcare costs happens in two stages:

**Social Security** reimburses part of costs according to a base rate called "Reimbursement Basis" (BR) or "Convention Rate" (TC)
**Complementary health insurance** completes reimbursement according to your contract's coverage

Concrete example: For a general practitioner consultation at the convention rate (26.50 euros), Social Security reimburses 70%, or 18.55 euros (minus 1 euro flat-rate contribution). The remainder (about 8 euros) is covered by complementary health insurance.

Coverage Levels

Complementary health insurance coverage is often expressed as a percentage of the Reimbursement Basis (BR) or in euros. Here's how to interpret them:

100% BR: The complementary insurance reimburses the ticket moderateur, i.e., what remains after Social Security reimbursement, within the convention rate limit. No excess fees are covered.

150% BR, 200% BR, etc.: The complementary insurance covers part of excess fees. The higher the percentage, the more excess fees are covered.

Euro allowance: For certain items (optical, dental, alternative medicine...), coverage may be expressed as a maximum amount per year or per equipment.

100% Sante (formerly RAC 0)

Since 2019, the "100% Sante" reform allows policyholders to access optical, audiology, and dental equipment with no out-of-pocket cost, thanks to joint action between Social Security and responsible complementary health insurance.

In optical: Quality frames and lenses are fully reimbursed. The 100% Sante basket offers a wide choice of frames and all types of corrective lenses.

In audiology: Class I hearing aids are fully covered, with the same minimum technical performance as Class II devices.

In dental: Crowns, bridges, and removable prostheses are 100% reimbursed for visible teeth and certain back teeth.

Choosing Your Complementary Health Insurance

Evaluating Your Needs

Choosing complementary health insurance should be adapted to your personal and family situation. Several criteria come into play:

Your health status: If you have regular needs (glasses, dental care, specialist consultations...), prioritize adapted coverage.

Your age: Needs evolve with age. Young people often need good optical coverage, while seniors may have greater hospitalization or audiology needs.

Your family situation: If you have children, check dependent coverage conditions (free or with surcharge) and specific coverage (orthodontics for example).

Your care habits: If you regularly consult practitioners who charge excess fees, good coverage of these fees is important.

Main Coverage Areas

Hospitalization: Check coverage for private rooms (daily allowance), hospital daily rate (21 euros per day in 2025), and surgeons' excess fees.

Routine care: General and specialist consultations, medications, tests, radiology... Beware of practitioners outside the care pathway who are less well reimbursed.

Optical: Coverage is often expressed as an allowance (for example 150 euros for frames, 200 euros per lens). Check renewal frequency (usually every 2 years unless correction changes).

Dental: Beyond 100% Sante, check coverage for prostheses outside the basket, implants (often not reimbursed by Social Security), and orthodontics.

Alternative medicine: Osteopathy, acupuncture, homeopathy... These treatments aren't reimbursed by Social Security. Some insurers offer dedicated allowances.

Complementary Solidarity Health Insurance (CSS)

Formerly called CMU-C and ACS, Complementary Solidarity Health Insurance is State aid for people with modest incomes. It provides free or less than one euro per day per person complementary health insurance, depending on household income.

**Access conditions** depend on household resources. Thresholds are revised annually. If you think you might qualify, you can run a simulation and apply on ameli.fr or through your health insurance fund.

Portability of Rights

If you leave a company (dismissal, end of fixed-term contract, mutual termination...) where you benefited from collective health insurance, you can keep this coverage free for a limited time. This is called "portability of rights."

The maintenance duration corresponds to your last employment contract's length, up to a maximum of 12 months. During this period, you continue to benefit from the same coverage without paying premiums.

Conclusion

Complementary health insurance is an important element of your social protection in France. Whether it's mandatory company insurance or an individual contract, it's essential to understand your coverage and adapt it to your needs.

Don't hesitate to inquire about Complementary Solidarity Health Insurance if you have modest income, and remember to regularly reassess your coverage as your situation evolves.
