For medical procedures, I think it makes sense to check ID - just for the potential testimonial "audit trail" in case of actual or purported malpractice.
"Are you CERTAIN that the X-ray we are looking it is of the plaintiff? How would you know if someone else showed up and claimed to be them? Is your memory completely infallible?" etc... It might not be of any real significance but poor process can make one side look like they don't have their sh*t together.
Every other industrialized country that I’ve ever been to has taken me at my word when I provided my name for medical procedures. It works fine and always has.
