<prompt> Human: Im not sure how to fix this. Got a hefty bill from my doctors office for a procedure that wasnt done. And its not an issue of me not understanding the code. Im pretty sure I would clearly remember and incision being made on my rectum for a rectal abscess. I dont have any abscesses on my body anywhere and that doctor never made any incision of any kind on me. The office is saying they wont correct it. I called my insurance company and they said there was nothing they could do. What are my options?  <response>: I would ask for proof from the doctor Then ask for a supervisor at the insurance company. Keep going up the chain of command Email all correspondence proof of time and date stamp Document everything who you talked to Date Time NameExtension Phone number Email I did this with another bill Great success bcz I had done all of the above Then I told them if they didnt correct it I was going to build them for my time correcting their errors
