How Healthcare Works in Luxembourg, and How to Register With the CNS

Luxembourg has one of the most generous health systems in Europe, but newcomers are often confused by how it is organised. This guide explains the basics: how you get covered, what the Caisse nationale de santé (CNS) pays, and what you do yourself.

Compulsory insurance, funded by contributions

Health cover in Luxembourg is compulsory and statutory. If you work here as an employee or self-employed person, you are insured by the CNS, the country's main health fund. The system is financed by social-security contributions deducted from earnings: in 2026 the employee's health-insurance share is about 3.05% of salary (2.80% for healthcare in kind plus 0.25% for cash benefits), the employer pays a matching share, and the State adds a further contribution.

Because it is contribution-based and not means-tested, cover does not depend on your income or health. Family members without their own income, such as a non-working spouse, partner or children, are co-insured free of charge under the main insured person.

How you get affiliated (registration)

Most people never have to apply themselves. When you start a job, your employer must declare you to the Centre commun de la sécurité sociale (CCSS) within 8 days, and you are then affiliated to the CNS automatically. If you are self-employed, you register yourself with the CCSS using a start-of-activity declaration, also within 8 days.

After affiliation you receive your social security card, which carries your 13-digit national identification number (matricule) — Luxembourg's personal identifier for all social-security matters. The card is issued automatically and arrives by post in about three weeks. To add co-insured family members, the main insured person submits a simple application to the CNS.

Note: before any of this, register as a resident at your local commune — that step comes first.

Free choice of doctor, and your card

Luxembourg has no gatekeeper system: you do not need to register with a family doctor, and you can go straight to a general practitioner or a specialist of your choice. You can change doctor whenever you wish.

Your social security card is two-sided. One side is your national card; the other is the European Health Insurance Card (EHIC), which covers urgent care during temporary stays in the EU, EEA, Switzerland and the UK. You present the card to every provider — doctors, hospitals, pharmacies and laboratories.

The reimbursement model and the patient share

Traditionally Luxembourg works on a pay-and-claim basis: you pay the doctor yourself, then the CNS reimburses most of the cost. For a standard in-office GP consultation the CNS tariff is €59.50, of which the CNS reimburses 88% (€52.36). The part you keep paying — the ticket modérateur (patient share) — is the remaining 12% (€7.14). For a home visit the tariff is €95, reimbursed at 80% (€76), leaving a 20% (€19) share. Children under 18 are reimbursed at 100%. Reimbursement applies to official CNS tariffs only — any fees a doctor charges above tariff are yours.

This is changing. Under Paiement Immédiat Direct (PID), rolled out since March 2024, a growing number of doctors and dentists bill the CNS directly so you only pay your own share on the spot — no more advancing the full amount. We cover the wider reimbursement changes in our companion piece on the CNS reimbursements 2026.

Supplementary insurance and cross-border workers

The CNS does not cover everything: your ticket modérateur, fee overruns, single hospital rooms, most glasses and dental prosthetics fall outside it. Many residents take supplementary insurance — the non-profit mutual CMCM or a private mutuelle (DKV, Foyer, AXA) — to fill those gaps. See our guide to supplementary health insurance for details.

Cross-border (frontalier) workers who live in France, Germany or Belgium but work in Luxembourg are insured by the CNS on the same terms as residents. To also get care at home, they register with their local fund using the S1 form (or equivalent), which the CNS issues after the employment declaration.
