Not sure about the charges being recovered from the insurer here - happens in the states - the medical insurance tends to pay hence the high number of ems services.
BUT, the charge you mention for rta or rtc as they are now called, is strictly a hospital charge for the a+e consultants treatment, although he may not actually ever see you. IT IS NOTHING TO DO WITH THE AMBULANCE SERVICE - even though we always get the blame for it!
