Health Insurance
The Luxembourg CNS system provides solid basic coverage, but gaps remain. A complementary health plan gives you shorter wait times, private hospital rooms, and full dental and optical reimbursement.

What does complementary health insurance cover?
Understanding health insurance in Luxembourg
How the Luxembourg health system works
Luxembourg operates a mandatory social security system through the Caisse Nationale de Santé (CNS). All employees, self-employed workers and residents contributing to social security are automatically covered. The CNS reimburses approximately 80–88% of standard medical costs, including GP visits, specialist consultations, hospital stays and prescriptions.
The remaining 12–20% - known as the ticket modérateur - is paid out of pocket by the patient. For dental prosthetics, optical care and alternative therapies, CNS reimbursement is limited or absent. This is where a complementary health plan fills the gap and can significantly reduce your out-of-pocket expenses.
What the CNS covers - and what it doesn't
The CNS provides solid baseline coverage, but several important areas remain only partially covered or excluded entirely:
- Hospitalization - Covered in a shared room. Private or semi-private rooms require a complementary plan.
- Dental care - Basic treatments are partially covered. Implants, crowns and orthodontics for adults have very limited reimbursement.
- Optical care - Glasses and contact lenses receive minimal CNS contribution. Laser surgery is typically not covered.
- Alternative medicine - Osteopathy, chiropractic, acupuncture and naturopathy are generally not reimbursed by the CNS.
- Worldwide coverage - Emergency care abroad is covered within the EU via the European Health Insurance Card, but coverage outside the EU is limited.
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. Best value for families or those who want complete peace of mind.
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, specific plans address the coordination between your home country and Luxembourg systems.
Dental, optical and alternative medicine coverage
These three areas represent the largest out-of-pocket expenses for Luxembourg residents - and the biggest reason to consider a complementary plan.
Dental: The CNS reimburses basic treatments like fillings and extractions at around 80%, but implants can cost €1,500–3,000 per tooth with minimal CNS contribution. A good complementary plan can reimburse 80–100% of dental costs including prosthetics and adult orthodontics.
Optical: With glasses costing €200–600 and the CNS contributing only a fraction, optical coverage in your complementary plan pays for itself quickly - especially for families with children who need regular eye exams and updated prescriptions.
Alternative medicine: Osteopathy sessions (€60–90 each), acupuncture and chiropractic are increasingly popular but not covered by the CNS. Most comprehensive plans include an annual allowance for these therapies.
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. Family plans often offer significant savings compared to individual policies.
- 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, complementary coverage can save hundreds of euros per year.
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 covers about 80-88% of standard medical costs, leaving you to pay the ticket modérateur (12-20%). A complementary plan covers this gap and adds benefits the CNS doesn't cover, such as single rooms, dental implants, and alternative medicine. Most Luxembourg residents find a complementary plan worthwhile for the peace of mind it provides.
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. We compare family packages across multiple insurers to find the best value for your household.
Are there waiting periods for complementary health plans?
Some plans apply waiting periods - typically 3 to 12 months - for dental prosthetics, optical care or maternity benefits. Basic ambulatory and hospitalization coverage usually starts immediately. We always clarify waiting periods before recommending a plan so there are no surprises.
What is the ticket modérateur and how much does it cost?
The ticket modérateur is the patient's share of medical costs after CNS reimbursement - typically 12% for GP visits, 12% for prescriptions, and up to 20% for certain specialist consultations. For a €50 GP visit, you would pay around €6 out of pocket. Over a year with regular visits, these co-payments can total several hundred euros - which a complementary plan covers.
Does complementary insurance cover pre-existing conditions?
Most insurers require a health questionnaire and may exclude specific pre-existing conditions or apply surcharges. However, some plans in Luxembourg offer guaranteed acceptance with modified terms. We compare policies from multiple providers to find the best option for your health profile.
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 - we help you understand exactly what is covered and where, so you avoid unexpected bills.
