This question was just raised among my friends who are having a similar accident. I will subjectivize the question for generality.
I am an European citizen. I am traveling in Europe, but unfortunately I left my EHIC card home. In my country, hospitals prefer to identify me by EHIC, but if I fail to show them they can compute my Social Security Number tax code to input it manually, as the EHIC card works as SSN card too.
Now I am in another European country, I have all my documents with me (local ID and passport as well), but forgot my EHIC/SSN card. I need to go hospital and will fail to show EHIC.
How do I fix this situation?
Will the hospital require me to pay a large bill? I can already prove I am an EU citizen and it is possible to get my EHIC information from my identity, so I hope the hospital in the hosting country will settle with my local National Healthcare, and eventually my NHS will send me a small bill according to my regulation.
In the specific: the patient is a Latvian traveling in Italy.
