Went to see my doctor and asked for certain type of XXXX for a procedure that it should of been covered by my medical plan. a month later I get a bill in the mail from the doctors office and the XXXX company. after several attempts with the doctors office they realized that it was a first time visit and it should be cover with my insurance plan also the XXXX should of been covered by my plan. they corrected the office visit bill but never corrected with the XXXX. 
I should not be paying for the XXXX bill since I did not requested those additional XXXX. 
my visit and XXXX should be paid by the insurance company in full. the extra XXXX was irrelevant to my procedure. there was no need to have added tests to the XXXX it was required. 
I called the insurance company and put the dr office in a conference call, they were going to call the XXXX to correct the bill and they did not. 

I have an outstanding credit history. I pay my bills on time. However if the bill does not belong to me to pay I will not pay it.
