Nah, I worked for docs for 2 years and we never asked to see ID, only insurance cards. Not even when they paid by check. We would not - legally *could* not - see a minor alone **unless it was in regards to reproductive health**. Not necessarily even birth control but a girl coming in for a Pap and routine check, or a guy coming in for an STD test. Mom or dad could send in a note however, giving us permission to treat their child, usually when grandma or aunt was bringing them in.
We had a few teens come in for various ailments without parent or note and in those cases we would call mom or dad and two of us would have to verify over the phone that we could see and treat the kid, then we’d note ‘S/W Mom on the phone, verbal permission to see patient’ on the notes for that visit. We never photocopied a single driver’s license though.
