Health insurance in Luxembourg
The CNS provides solid basic cover but leaves costs for you to pay: co-payments, dental prostheses, optical care, a private room. A complementary health plan covers all or part of them, within the ceilings of each plan.

How the Luxembourg health system works
Luxembourg operates a mandatory social security system run by the Caisse nationale de santé (CNS). Employees are affiliated through their employer, the self-employed when they register. The CNS reimburses 88% of consultations with a GP or specialist (100% under 18) at the agreed rates, and medicines at 80% at the standard rate, 40% or 100% depending on their category.
The remaining share, known as the ticket modérateur, is yours to pay. For dental prostheses, optical care, a private room and alternative medicine, CNS cover is limited or absent. This is where a complementary health plan comes in, within the ceilings of each plan.
What the CNS covers - and what it doesn't
The CNS provides solid baseline cover, but several items are only partly covered or excluded entirely:
- Hospitalisation: a private room is not covered by the CNS; the supplement is a matter for a complementary plan.
- Dental care: routine care is covered at the agreed rates, but prostheses (crowns, bridges, implants) are reimbursed at only 80%, or 100% if you can show an annual preventive visit over the two previous years. Orthodontics is covered only under conditions.
- Optical care: the frame is capped at €30 every three years; lenses are covered at the agreed rates.
- Alternative medicine: osteopathy, chiropractic, acupuncture and naturopathy are generally not reimbursed by the CNS.
- Care abroad: emergency care is covered within the EU via the European Health Insurance Card, but cover outside the EU is limited.
For every item with its 2026 rate, see our table of CNS reimbursements; for hospital care, see our article on hospital stays in Luxembourg.
Types of complementary health plans
Complementary health plans in Luxembourg vary in scope and price. Understanding the main categories helps you choose wisely:
- Basic ambulatory plans - Cover the ticket modérateur on GP and specialist visits, prescriptions and basic diagnostics. Affordable starting point for healthy individuals.
- Hospitalization plans - Focus on private room upgrades, free choice of surgeon and extended in-hospital benefits. Essential if you value comfort during hospital stays.
- Comprehensive plans - Combine ambulatory, hospital, dental, optical and alternative medicine coverage. The most complete, and therefore the most expensive.
Premiums depend on your age, chosen coverage level and any pre-existing conditions. Most plans allow you to add dental and optical modules separately. If you are an expat or cross-border worker, choose a top-up plan designed for the Luxembourg scheme: CMCM, for example, is open to cross-border workers from the neighbouring regions.
Dental, optical and alternative medicine coverage
These three items account for most out-of-pocket costs, and are the main reason to consider a complementary plan.
Dental: routine care is covered at the agreed rates, but prostheses are reimbursed at only 80% (100% with an annual preventive visit over the two previous years), and adult orthodontics remains largely out of pocket. A complementary plan reimburses beyond that, within its ceilings: up to €3,500 a year for prostheses at CMCM, for example. Our article on what the CNS reimburses for dental care goes through each item.
Optical: the CNS caps the frame at €30 every three years. For a quality frame or progressive lenses, most of the cost stays out of pocket without a top-up plan; DKV, for example, provides €500 of eyewear every two years in its EASY HEALTH plan.
Alternative medicine: osteopathy, acupuncture and chiropractic are generally not reimbursed by the CNS. Some plans include an annual allowance for these treatments.
Who benefits most from a complementary health plan
While anyone can benefit from reduced out-of-pocket costs, certain profiles find a complementary plan particularly valuable:
- Families with children - Paediatric dental, orthodontics and regular check-ups add up quickly. At CMCM, the whole family is co-insured at no extra cost.
- Expats and new residents - Coming from a country with different healthcare norms, you may expect a level of coverage that the CNS alone cannot provide. A complementary plan bridges this gap.
- Professionals over 40 - As preventive check-ups and specialist visits increase with age, the ticket modérateur becomes a meaningful expense that complementary coverage offsets.
- Anyone needing regular therapy - If you rely on physiotherapy, osteopathy or ongoing dental work, out-of-pocket costs add up quickly, and a complementary plan absorbs part of them.
If you also need to protect your loved ones financially, consider exploring life insurance alongside your health coverage.
Frequently asked questions about health insurance in Luxembourg
Do I need private health insurance if I have CNS?
The CNS reimburses 88% of a consultation (100% under 18) and, for medicines, 80% at the standard rate, 40% or 100% depending on their category. A complementary plan covers all or part of the rest and adds what the CNS barely covers or does not cover: a private room, dental prostheses, optical care, alternative medicine.
Can my family be covered under one plan?
Yes. Most insurers offer family plans that cover your spouse and dependent children at a reduced rate. A licensed partner insurer can propose the family plan suited to your situation.
Are there waiting periods for complementary health plans?
Most complementary plans apply a waiting period of about three months, up to eight months for some benefits, dental in particular. These periods are often waived if you were already covered. A licensed partner insurer checks them before proposing a plan.
What is the ticket modérateur and how much does it cost?
It is the share the CNS does not reimburse: 12% of a consultation, 20% of a medicine reimbursed at the standard rate (80%), more for a medicine at the reduced rate (40%). For a €50 consultation, about €6 remains for you to pay. Over a year of regular care these amounts add up: that is the share a complementary plan covers.
Does complementary insurance cover pre-existing conditions?
Private insurers generally require a medical questionnaire and may exclude certain conditions or apply a surcharge. CMCM, a mutual, accepts members with no medical questionnaire and no age limit, after a three-month waiting period. A licensed partner insurer can propose the plan suited to your situation.
How do health costs work for cross-border workers?
As a frontalier working in Luxembourg, you contribute to the CNS and can receive healthcare in both Luxembourg and your country of residence. A complementary plan can cover the gaps in both systems. Coordination rules between countries can be complex: a licensed partner insurer can check what is covered, and where, before you choose.
Dentist, orthodontics, glasses: what the CNS reimburses and what you still pay
The national health fund reimburses everyday care very well. The gaps are elsewhere, and they are precise: dental prostheses, orthodontics, eyewear, private room.
