Key points
- Luxembourg runs the Bismarck model: compulsory social health insurance administered by a single fund, the National Health Fund (Caisse Nationale de Santé, CNS).
- Coverage is universal on paper: 100% of the population is eligible for a core set of services, and the compulsory scheme covered 92.6% of residents in 2023 — about a third of the people covered are cross-border workers from Belgium, France and Germany.
- Care is delivered by public and private providers under binding agreements negotiated by the CNS; the Ministry of Health and Social Security plans hospital infrastructure but has no legal mandate to plan the outpatient sector.
- Patients pay cost-sharing on a number of services, and households paid 8.8% of health spending out of pocket in 2023 (WHO Global Health Expenditure Database) — the lowest share stated in any OECD profile in this set. About two thirds of residents also buy voluntary health insurance.
- Life expectancy at birth was 83.4 years in 2023, and health spending was 5.9% of GDP in 2024 (OECD Health at a Glance 2025).
Direct answer: Luxembourg runs the Bismarck model: compulsory social health insurance administered by a single fund — the National Health Fund (Caisse Nationale de Santé, CNS) — in a highly centralised system governed by the Ministry of Health and Social Security. Coverage is universal on paper: 100% of the population is eligible for a core set of services, and the compulsory scheme covered 92.6% of residents in 2023, with about a third of the people covered being cross-border workers from Belgium, France and Germany. Care is delivered by public and private providers under binding agreements negotiated by the CNS. Patients pay cost-sharing on a number of services, and households paid 8.8% of health spending out of pocket in 2023 (WHO Global Health Expenditure Database) — the lowest share stated in any OECD profile in this set. Life expectancy at birth was 83.4 years in 2023 — and healthy life expectancy 71.4 years — and health spending was 5.9% of GDP in 2024 (OECD Health at a Glance 2025; WHO Global Health Estimates, October 2026).

How the system works
Luxembourg’s health system is highly centralised. It operates a compulsory social health insurance scheme run by the National Health Fund (Caisse Nationale de Santé, CNS), which is responsible for health and long-term care insurance. The Ministry of Health and Social Security, with its Health Directorate, organises, plans and partially finances healthcare and public health services. While the Ministry plans hospital infrastructure and services, it has no legal mandate to plan for the outpatient sector. The CNS negotiates agreements with all providers in both the hospital and outpatient sectors, and these agreements are binding for providers delivering services covered by the scheme.
Purchasing the compulsory scheme is compulsory for everyone who is economically active or receiving replacement income. In 2023, the scheme covered 92.6% of the resident population. Among the people covered, about 36% were non-residents working in Luxembourg as cross-border employees from Belgium, France and Germany. Exemptions exist for employees of international organisations, which was 11,900 people in 2022, and their dependents. The workforce is unusually international: with 4.0 physicians per 1,000 population, Luxembourg’s physician density is slightly below the EU average of 4.3, but almost 30% of its doctors were general practitioners in 2023, against 20% across the EU. Nurses numbered 14.2 per 1,000 population, well above the EU average of 8.5 — but, like the doctors, the nursing workforce relies heavily on foreign-trained professionals, and new domestic medical and nursing education programmes are only now being built up.
Who pays, and what people pay
Shared contributions from the state, employers and employees pay for the system through the CNS. Public financing constituted the major source of health spending: government and compulsory coverage schemes accounted for 85% of current health spending in 2023, well above the EU average of 80%, and mandatory prepayment covered 86% of spending (OECD Health at a Glance 2025). What patients pay is small by European standards: out-of-pocket spending accounted for only 10% of health spending in 2023 in the Country Health Profile, 8.8% in the WHO Global Health Expenditure Database, against an EU average of 16% — the lowest share stated in any OECD profile in this set. Voluntary health insurance premiums accounted for 4.4% of health spending, and about two thirds of the resident population purchase it to cover complementary or supplementary services.
What is free, and what is not
Free at the point of use: covered services under the compulsory scheme, with the CNS package described as comprehensive. What is not free is the margin: cost-sharing is required for a number of services, and the share of out-of-pocket spending on retail pharmaceuticals remains relatively high at 30%, though below the EU average of 36%. The boundary is narrow by European standards: only 1.0% of people reported unmet needs for medical care, and financial protection is strong — though coverage gaps remain for the small population group without a permanent address.
How it compares
Luxembourg spends 5.9% of GDP on health — below the OECD average of 9.3% — and $8,087 per person, above the OECD average of $5,967 (USD PPP, 2024). Its life expectancy of 83.4 years is 2.3 years above the OECD average of 81.1 years (OECD Health at a Glance 2025), among the highest in this set. Its distinguishing feature is the combination of a small, rich, highly centralised system with an unusually international workforce and patient base: 14.2 nurses per 1,000 people, the fourth-highest nurse density in this set after Switzerland (18.8), Norway (15.6) and Iceland (15.2); 86% of people satisfied with the availability of quality healthcare, tied with Belgium for the second-highest satisfaction level in the OECD table after Switzerland (89%); and avoidable mortality of 123 deaths per 100,000 people, among the lowest in the OECD. The GDP share looks low partly because Luxembourg’s GDP is inflated by financial services and cross-border labour — against gross national income, health spending was 8.3% in 2023.

Frequently asked questions
Is Luxembourg healthcare free?
Covered services under the compulsory scheme carry no bill at the point of use beyond cost-sharing: patients pay charges on a number of services, and about two thirds of residents buy voluntary health insurance to cover complementary or supplementary services.
What is the CNS?
The Caisse Nationale de Santé (National Health Fund): the single fund that runs Luxembourg's compulsory social health insurance and long-term care insurance, negotiating binding agreements with all providers in the hospital and outpatient sectors.
Why do so many people covered by Luxembourg's health insurance live outside the country?
About a third of the people covered by the compulsory scheme are cross-border workers — non-residents working in Luxembourg from Belgium, France and Germany — who are insured through their Luxembourg employment.
