Have you ever heard of a doctor charging you for this? (details follow)

“John” broke his neck and had a neurologist come to the ER and attempt to treat him. John was released two days later. Shortly, John began receiving bills from ANOTHER neurologist for $40 a day John had never met. So John called the office of the other doctor about the bills and was told “those are bills just IN CASE (the new) doctor has to be called at some point!” John never paid a dime and they never pushed it.
