Regarding health care for tourists in Italy being covered, some excerpts from a couple of prior threads:
"Italy may have "free national healthcare" but I believe that's primarily for residents who pay taxes there. I've used emergency medical care in Italy and part way through my care, I was presented with a bill summary that was already thousands of Euro at that point. Thankfully I always travel with comprehensive travel medical insurance, and I let them deal with that."
"My father in law had to go to the ER last year in Milán, and as soon as he arrived, they asked for his passport and kept it until he left. He was handed a bill, that was about €700, code green or yellow, he paid it and then his insurance reimbursed it."
This from an Italian citizen:
"It isn't free for Italians and it shouldn't be free for tourists, either. They are supposed to ask for your name and address to send you a bill. Years ago, if you did not make clear you had a travel insurance, most employees registered tourists as undocumented foreigners and the administrative office decided not to waste time mailing bills nobody would have paid.These days this way of treating foreigners is more and more uncommon. If you can't pay right away, sooner or later you should receive a letter from Italy asking for the (Italian) cost of the medical treatment you received."
We've ALWAYS bought insurance that includes medical evac when traveling abroad. That's the cost that can really break you if you need it.
