At the time of this visit to the hospital I was fully insured. I was not made aware that this doctor was NOT a regular on staff physician for XXXX XXXX XXXX and would send a separate bill for his services. My insurance has a binding agreement with this hospital for charges and this charge far exceeded that agreement. I am NOT responsible for these charges. 
XXXX such as this should be made to function under the agreed upon charges as stated in the contract with my medical insurance.
