Business ProfileforKeck Hospital of USC

am writing because my USC **** Medicine medical bill for an office visit amounts to over $266. I have been waiting over a 7 month from a response for billing. I was told that I would only be responsible for my copayment for a specialist visit. I was not informed that this visit was going to be billed with the code as if I was seen in the hospital. I asked multiple questions before making the appointment for this doctor in regards to my co-payment and what the insurance would cover, and at no time did they inform me that they were going to code this visit like they did. I work for a medical office and we are supposed to disclose if it is going to be billed as anything other than a specialist or professional office visit. I am requesting that someone call me as soon as possible to rectify this situation. If I would have known that this office or network codes and bills in this way, I would have never made an appointment. I spoke with my insurance at the time and they also told me that the way it was billed was overbilling. I made multiple attempts to speak with a supervisor for over 7 months and nobody called me back until today when I spoke with ******. I have been waiting 7 months for a response to my situation and I just now got a response which is unacceptable. I am requesting that someone email and call me in regards to this, because I don't understand how patients are not told that they are going to be billed as not just a specialist but a hospital specialist visit. ******************************
