English Dept of pensions FORM S! -

This NHS Link tells you to register it with INPS, but I'm sure it's your local ASL. You should then get a Italian medical card.

Hi, when we went to register for the health service to get ourTessera Sanitaria  - first with the GP and then with ASL - they looked blankly at the S1 form from the UK. Even though we think that we are not entitled to health cover without them reclaiming the costs from the NHS in UK, we were told - "you have a residency and an Italian ID card, you are paying our taxes, so you get our health cover" !

A lot of Italian healthcare isI believe resident based, but the  application of the rules seems to vary from comune to comune. Hopefully you don't need it too much!
