Affiliation: automatic for employees
Luxembourg's statutory health insurance is managed by the Caisse nationale de santé (CNS). When you start work, your employer declares you to the Joint Social Security Centre (CCSS), which registers you with the social security system. You receive a social security number and, later, a social security card by post.
Your spouse or registered partner and your children can usually be covered as co-insured family members, subject to conditions, without paying additional contributions. Make sure your employer or the CCSS has their details.
Self-employed people and people without an employer register themselves; the procedure is on Guichet.lu.
Keep your social security number handy. You will need it for almost every health-related contact, from booking a doctor to buying medication.
How paying and reimbursement work
For a doctor's consultation, the traditional system in Luxembourg is pay first, be reimbursed later. You pay the doctor, receive a statement of fees, and the CNS reimburses the statutory share to your bank account.
In practice, digital tools have made this faster. Many practices and pharmacies now handle direct billing for part or all of the cost, and the CNS offers online services for submitting claims and following reimbursements. Ask your doctor how they bill.
The CNS reimburses a defined share of each medical act, according to its official tariffs. The remaining part, and some services the CNS covers only partly, such as dental and optical care, are where complementary insurance comes in.
For people in financial difficulty, the tiers payant social allows the CNS to pay the doctor directly, so that the patient does not have to advance the money. It is granted through the social offices of the communes.
Complementary insurance
Many residents take out complementary health insurance to cover what the CNS does not fully reimburse: part of the patient share, dental care, glasses, hospital room supplements and some alternative treatments. Options include mutual societies and private insurers. Some employers offer it as a benefit; ask before paying for your own.
Finding a doctor
Luxembourg does not assign you a general practitioner. You choose one. You can also designate a médecin référent, a GP who coordinates your care and keeps your medical file up to date.
- Ask colleagues and neighbours for recommendations; word of mouth works well.
- Most doctors speak several languages. Many work in French, Luxembourgish and German, and English is common, particularly in Luxembourg City.
- Book online or by phone. Waiting times vary, and some GPs are not taking new patients.
- For specialists, you can book directly in most cases.
Pharmacies
Pharmacies are identified by a green cross. Prescription medication is dispensed with your prescription and your social security details; the pharmacy often applies the CNS reimbursement directly.
Outside normal hours, a pharmacie de garde (on-duty pharmacy) is always open in each region. The rota is published online and displayed in pharmacy windows.
At night, at weekends and in emergencies
- Emergencies: call 112, the European emergency number, for an ambulance, the fire service or urgent medical help.
- Hospital emergency departments: Luxembourg's hospitals operate an on-duty rota for emergency services. The hospital on duty is published daily; check before you go.
- Out-of-hours GP: medical centres provide GP consultations in the evenings, at weekends and on public holidays for non-life-threatening problems. Check the current addresses and hours online.
It is worth saving 112 and the link to the on-duty rota in your phone during your first week.
Before and after you arrive
- Bring your medical history: prescriptions, vaccination records, and summaries of any ongoing treatment, ideally in English or French.
- Keep your European Health Insurance Card from your previous country if you are arriving from elsewhere in the EU, until your Luxembourg affiliation is active.
- Check your employment contract for complementary insurance.
- Register with the commune promptly; many administrative steps depend on it. See our guide to registering with your commune.
Cross-border residents
If you work in Luxembourg but live in France, Belgium or Germany, you are generally insured in Luxembourg through your job, and there are arrangements for receiving care in your country of residence. The rules for cross-border workers are specific; our guide to living in the city or across the border covers the broader picture.
Questions we are often asked
Can I see a doctor before my social security card arrives?
Yes. Your affiliation starts with your employment, not with the card. Keep your social security number or a certificate of affiliation from your employer, and bring it to your first appointments.
Do doctors speak English?
Many do, particularly in Luxembourg City, and most practices say which languages they work in. If language matters, ask when you book.
What about dental care?
Dentists are part of the system, but the CNS reimburses only part of many dental treatments. This is one of the main reasons people take complementary insurance.
Do I need a referral to see a specialist?
In most cases you can book a specialist directly. Having a médecin référent is still useful, because your GP coordinates care and keeps your records together.
Is there a waiting time for specialists?
It varies widely by speciality. For non-urgent appointments, booking early and being flexible about location helps.
Our take
Luxembourg's health system is comprehensive and, for employees, largely automatic. The adjustments are practical: choosing your own doctor, getting used to paying and being reimbursed, and knowing where to go at night. Sorting those three in your first weeks makes the rest straightforward.
