E111
Although a passport is often enough in many countries to get medical
treatment, to facilitate the process of getting immediate health care it
is good if you have the E111 form. This proves that you are affiliated to
a health insurance scheme in a Member State and allows you to receive
immediate health care in the country in which you are staying temporarily.
So just pick one up from your national health insurance authorities before
you travel.
You will still be entitled to receive immediate health care even if you do
not have an E111 form, but you may then be asked to pay for everything.
After, you can claim a refund from the authorities responsible for your
health insurance scheme.
