My son is epileptic (well under control now). Many years ago, driving through Rye New York he had a seizure in the back seat. We scooted to the nearest hospital. He was in "status epilepticus" which means they couldn't stop the seizure. A neurologist came in and ordered him to be put on a breathing bag and left.
$1,500. On our insurance, of course.
My wife called up his office and BCBS and pointed out the absurdity. It took a lot of back and forth but finally they dropped the charge.
