It's hard as one having free (state paid) healthcare in EU, to imagine anything but just going to the doctor, and the doctor seeing to it, that you get the correct treatment.
No paperwork, no hassle, no bill.
I can't imagine why USA hasn't introduced something similar yet, but prefer all that bureaucracy that only makes the whole process way more expensive. Just to make sure some unemployed poor guy doesn't get free treatment!!
USA is a psychopathic society.
