I believe he's referring to National Insurance. But as far as I remember NI is the government pension scheme and not related to health insurance. I can't remember if I had to show my NI card when going to the doctor when I was at university there. Later on when I was working I normally paid for my own private doctors, due to my experience with the horrible NHS system during my student days.
