The European Health Insurance Card gives access to any state-provided medical treatment that becomes necessary during your stay because of either illness or an accident. It includes treatment of a chronic or pre-existing medical condition that becomes necessary during your visit.
If you require kidney dialysis or oxygen therapy you have to make arrangements in advance for this care. To arrange for kidney dialysis while you are away, contact the renal unit in the country you wish to travel before you trip.
Your European Health Insurance Card should cover you for routine maternity care while you are away. However, if you are going to another country specifically to have your baby, you will need an E112 form.
It is important to be aware, that the European Health Insurance Card gives access to reduced-cost or free medical treatment from state healthcare providers and allows you to be treated on the same basis as a resident of the country you are visiting i.e. you may have to pay a patient contribution (co-payment).
Information about necessary healthcare services for European Health Insurance Card holders in different countries can be found on the website of the European Commission: http://ec.europa.eu/social/main.jsp?catId=1021&langId=en
Remember to check that your European Health Insurance Card is still valid before you travel!
