I suspect the bill was wrong, and that is no reason to turn the doctor into a state employee who responds only to his union bosses.
Actually it is a number of bills. The hospital bills add up to about $9,000. Then the doctor's bills started arriving, at least $3,000 worth. He is questioning the charges, one being $672 per day for a wearing a heart monitor. Then there are lab test bills, etc.
He has many different charges to figure out and then to challenge. I suspect that he will get nowhere. Basically he is being treated upon as a nobody with no money, no power, and no one to turn to.
