The European Health Insurance Card (EHIC) makes it easier for people from the European Union’s 27 Member States plus Iceland, Liechtenstein, Norway and Switzerland to access healthcare services during temporary visits abroad. This also includes emergency treatment such as for burn injuries.

What are the practical benefits of the card? 
For every EU citizen planning to travel it is advised to obtain a card.
The card ensures that you will get the same access to public sector health care (e.g. a doctor, a pharmacy, a hospital or a health care centre) as nationals of the country you are visiting. If you have to receive medical attention in a country that charges for health care, you will be reimbursed either immediately, or after you go home to your own country. The idea is that you are given the care you need to allow you to continue with your stay.
However, it is important to note that the card does not cover your health care costs while abroad if you are travelling in order to obtain treatment for an illness or injury that you had before travelling. Nor does the card cover you for private sector health care providers.”
