Health Insurance Luxembourg 2026 : CNS and Supplementary Cover Guide
The Luxembourg Healthcare System in 2026
Luxembourg has a high-performing social security system managed by the CNS (Caisse Nationale de Sante). All residents and workers — including cross-border commuters — contribute to the CNS, which reimburses on average 80 to 95% of medical costs depending on the type of care.
Despite this high coverage level, many residents and cross-border workers take out supplementary health insurance to cover remaining costs — particularly dental care, optical care, private hospital rooms, and complementary medicine.
What the CNS Covers
| Service | CNS reimbursement rate | Out-of-pocket cost |
|---|---|---|
| General practitioner consultation | 88% | EUR 5-8 |
| Specialist consultation | 80-88% | EUR 10-30 |
| Hospitalisation (shared room) | ~100% | Daily flat rate ~EUR 25/day |
| Medicines (positive list) | 80-100% | EUR 0-10 |
| Dental treatment (conservative) | 80% | EUR 20-100 |
| Dental prostheses | ~50% | EUR 500-3,000 |
| Glasses/contact lenses | Fixed amount (~EUR 60) | EUR 200-500 |
Why Take Out Supplementary Cover?
- Private room: EUR 80-200/day supplement not reimbursed by CNS
- Dental care: implants, orthodontics, prostheses — often high out-of-pocket costs
- Optical care: CNS flat rate insufficient for progressive lenses or quality frames

- Income protection: top-up daily benefits during extended sick leave
