European Health Insurance refers to a system that allows citizens of European Union (EU) member states to access healthcare services in other EU countries. This system ensures that individuals can receive necessary medical treatment while traveling or living abroad, without facing excessive costs. To benefit from this system, individuals must carry a European Health Insurance Card (EHIC), which proves their entitlement to healthcare. The card allows them to receive treatment under the same conditions as residents of the host country, ensuring that essential healthcare is accessible across borders within the EU.
