How does Luxembourg's healthcare system work?

88% reimbursement, no compulsory GP, 100% cover for children. Welcome to one of the best healthcare systems in Europe. Here's everything you need to know about the Luxembourg health system.

How is Luxembourg's healthcare system structured?

To understand how the Luxembourg healthcare system works, we first need to identify the three organisations that orchestrate your healthcare pathway and reimbursements. If you don't have time to read this article, here's a video to help you understand it all in just a few minutes:

The CCSS: your gateway to the system

The Centre Commun de la Sécurité Sociale (CCSS) is the body that manages all entries into the system.

Its main role is affiliation. As soon as you start working in Luxembourg, your employer must make an entry declaration to the CCSS within 8 days of your recruitment.

At that point, the CCSS will allocate your national registration number with 13 digits. This unique number identifies you throughout the Luxembourg social protection system. You will keep it throughout your working life in the Grand Duchy.

The CCSS does not manage your healthcare reimbursements. Its role is limited to affiliation and general coordination of social security. When it comes to your healthcare, another player comes into play.

The CNS: the operational heart of the healthcare system

The Caisse Nationale de Santé (CNS) is the body with which you will interact on a daily basis for all matters relating to your health.

The CNS has a number of key missions:

• The management of medical reimbursements The CNS reimburses you for the following expenses: visits to doctors, purchases of medicines from pharmacies, dental care, hospitalisation and medical examinations. Every time you consult a healthcare professional, the CNS handles your reimbursement.
• Payment of financial compensation If you are off work for an extended period (more than 77 days), the CNS will take over from your employer and pay you compensation equal to 100% of your reference salary.
• Managing co-insurance If you want your spouse and children to benefit from your health cover, you should contact the CNS.
• Negotiating agreements The CNS establishes official tariffs with doctors and healthcare professionals. These tariffs serve as the basis for reimbursements.

If you are employed in the private sector or self-employed, the CNS is your main contact for all your health issues. You will receive your CNS social security card approximately 15 days after your declaration of entry.

The CMSS: arbitrating complex situations

The Social Security Medical Inspectorate (CMSS) intervenes in medical cases requiring in-depth assessment.

The CMSS is not an organisation that you contact directly. It is the CMSS that may contact you in certain situations:

• Extended sick leave If you are unable to work for several weeks or months, the CMSS may ask to examine you to verify the medical reality of your situation.
• Invalidity pension applications When a person can no longer work permanently, the CMSS assesses the degree of disability.
• Recognition of dependence For elderly or disabled people requiring daily assistance, the CMSS determines the level of dependency.

The CMSS works with medical officers who examine medical files and, if necessary, summon insured persons for further examinations. Its role is to ensure that social security benefits correspond to actual medical situations.

The interaction between the three organisations

In practical terms, here's how these three players work together in your journey:

1. Your employer declares you to the CCSS → You obtain your social security number
2. The CCSS automatically affiliates you to the CNS → You receive your social security card
3. You are consulting a doctor → The CNS manages your reimbursement
4. In complex situations (prolonged stoppage, disability) → The CMSS intervenes for assessment

This three-tier organisation may seem complex, but it is actually very fluid for the insured. Most of the time, you only interact with the CNS for your day-to-day care.

How does affiliation to Luxembourg social security work?

Membership of the Luxembourg health system is based on a simple principle: if you work, you contribute and are automatically covered.

Membership is automatic 100%

Unlike other countries where joining the scheme can involve complex administrative procedures, in Luxembourg everything is automatic for employees.

From your first day at work :

• You pay social security contributions (contributions are deducted directly from your salary)
• You are immediately protected
• Your cover starts with no waiting period

This automaticity is enshrined in Luxembourg law. No organisation can refuse to cover you, whatever your age, state of health or medical history. There is no medical questionnaire to complete.

The entry declaration mechanism

For employees, your employer takes care of everything. Within 8 days of your hiring, he will file your declaration of entry with the CCSS. This declaration contains :

• Your complete identity
• Your contract start date
• Your position and salary
• Your status (full-time, part-time, permanent or fixed-term contract)

Once this declaration has been made, the system starts up automatically. You do not need to take any action.

For the self-employed, things work slightly differently. You must make your own declaration of entry to the CCSS, also within a maximum of 8 days of starting work. You fill in the Declaration of entry for self-employed workers« form» with the necessary supporting documents (authorisation of establishment, documents proving your activity).

The principle of solidarity and non-discrimination

The Luxembourg system applies a principle of absolute solidarity: everyone contributes according to their income, so everyone is covered in the same way.

This means:

• No increase in contributions for people with a medical history
• No refusal of cover for certain medical conditions
• No limit on reimbursement based on pre-existing health condition

A 25-year-old in perfect health and a 50-year-old with several chronic illnesses benefit from exactly the same level of cover and pay the same contributions (for the same salary).

Co-insurance: extending protection to your family

One of the most advantageous mechanisms in the Luxembourg system is the free family co-insurance.

If you are affiliated to the CNS, your spouse and children can be covered free of charge under certain conditions :

• Your spouse does not work or works less than 16 hours a week
• Your children are under 30 and not working

Coinsurance is not automatic. You must make a specific request to the CNS Co-Insurance Department, providing the appropriate supporting documents (family record book, marriage certificate, proof of employment status).

Once accepted, your family benefits from exactly the same reimbursements as you, without paying any additional contributions. This is a considerable financial advantage, particularly for families with several children.

Special cases of affiliation

• Cross-border commuters If you live in France, Belgium or Germany and work in Luxembourg, you are automatically affiliated to the CNS by your Luxembourg employer. At the same time, you retain your rights in your country of residence, creating exceptional double cover.
• Unemployed people If you settle in Luxembourg without having found a job, you must take out voluntary insurance at €151.41 per month. Without health cover, you cannot legally reside in Luxembourg.

Freedom of choice and healthcare pathways: how does it work?

One of the most appreciated features of the Luxembourg system is no constraints on your choice of doctors.

No compulsory GP

Unlike in France, where you have to declare a general practitioner and systematically go through him or her to access specialists (on pain of a reduction in reimbursement), in Luxembourg you have to declare a general practitioner and systematically go through him or her to access specialists (on pain of a reduction in reimbursement), you consult who you want, when you want.

• Do you have back pain? You can make an appointment directly with a rheumatologist or physiotherapist.
• Do you have a skin problem? Call a dermatologist directly.
• Would you like to have a check-up by a cardiologist? There's no need to go to a GP first.

This freedom applies to all healthcare professionals: general practitioners, specialists, dentists, psychologists, physiotherapists and midwives. Your reimbursements are strictly identical, regardless of the professional you consult.

Very short access times to care

This freedom of choice is accompanied by an extremely appreciable practical reality: short turnaround times for appointments.

While in France it can take up to 6 months to get an appointment with a dermatologist, and sometimes longer in some regions, in Luxembourg you can usually see a dermatologist within a week of calling. For some specialists, appointments are available within 48 hours.

There are several reasons for this speed:

• A high number of doctors per inhabitant
• Efficient organisation of medical practices
• A working population that mainly consults at the end of the day, freeing up daytime slots
• A well-funded healthcare system that allows doctors to maintain their availability

Setting medical tariffs

All the consultation rates are officially established by the CNS in a precise nomenclature. These tariffs are public and identical throughout Luxembourg. In theory, there are no geographical variations, although there may be more pronounced fee overruns in larger towns.

Because that's the 2nd point: in Luxembourg, extra charges are authorised. Doctors may charge more than the CNS rate if they wish. But he must clearly inform you of his fees before the consultation. In this case, the CNS will only reimburse its share calculated on the basis of the official tariff. You are responsible for the remainder, unless you have taken out a complementary health insurance which covers overruns.

How do health reimbursements work?

There are two systems:

• The classic system, where you pay in advance. You must send the invoice to the CNS and then receive the refund in your bank account a few weeks or months later.
• The new Immediate Direct Payment (PID). This is a third-party payment system whereby the CNS portion is paid directly to the doctor. In this case, you only have to pay the complementary part.

How is sick leave reimbursed in Luxembourg?

Luxembourg boasts one of the most generous sickness benefit systems in Europe. 100% is reimbursed for sick leave from the 1st day. There is no waiting period for reimbursement.

The system operates in 2 phases:

Phase 1: The first 77 days of stopping

If you fall ill and cannot work :

• Your salary is maintained at 100% without any discount
• Compensation starts from day one (no waiting period)
• Your employer continues to pay your salary as normal
• This lasts until the end of the month in which your 77th day of sick leave falls.

Example: you fall ill on 15 March and your sick leave is extended. Your 77th day of sick leave falls on 30 May. You will receive 100% of your salary up to and including 31 May. During this period, your employer pays your salary, but 80% of it is reimbursed by the French social security system. Employers' Mutual Insurance. This mechanism is totally transparent for you.

Phase 2: After 77 days

If you are unable to work for more than 77 days, the CNS takes over with the’cash sick pay :

• It corresponds to 100% of your reference salary
• It is capped at 5 times the social minimum wage (approximately €13,000 per month in 2025)
• It can be paid up to 78 weeks over a 104-week period

In practical terms, if you have a serious accident or a long-term illness, you can receive the equivalent of your full salary for almost 18 months. It's an exceptional form of social protection that protects you from financial hardship in the event of a serious blow.

How is maternity leave reimbursed in Luxembourg?

For pregnant women, Luxembourg offers particularly advantageous protection.

Maternity leave lasts for a total of 20 weeks

• 8 weeks before the expected date of delivery
• 12 weeks after giving birth

You will be paid 100% of your salary for the duration of your leave., There is no ceiling (unlike sick pay).

Pregnancy-related care and expenses are 100% reimbursed by the CNS.

• All ultrasound scans, unlimited in number
• All antenatal consultations with the gynaecologist
• Medical tests and examinations
• Childbirth and the maternity ward
• Post-natal consultations

Additional parental leave Parental leave: after maternity leave, you can take 4 to 6 months' parental leave on a full-time basis (or spread over a longer period on a part-time basis). This leave is paid and can be taken by either the mother or the father.
