Best Health Insurance in Belgium

8 insurers ranked and reviewed · Updated May 2026

Sources:Test-Achats / Test-Aankoop

Healthcare System Overview

Belgium operates a mandatory social health insurance system where all residents must register with one of several non-profit health insurance funds (mutualites/ziekenfondsen). These funds reimburse approximately 75% of medical costs. The mandatory system is complemented by an active supplementary/private health insurance market. All mutualites offer the same core statutory benefits — differentiation is in supplementary coverage, service quality, and additional perks.
