I used ZocDoc to seach for a back doctor using my insurance which is Cigna Open Access Plus. It stated that Dr. Paul M. Brisson, MD was in my network so I booked an appointment with him 1 week in advance, on Monday, October 29th, 2018.' I arrive today at the office and tell the Office Person my name. She confirmed with her computer that I have an appointment. She then tells me that Dr. Brinsson was not in Cigna Open Access Plus Network and my fee would be $540.00 to for the office visit. She also adds that he is never in the office on Mondays. I asked: So why would accept the appointment Zocdoc if he is not in the office? Why does Zocdoc state you Dr. Brinsson is in Cigna Open Access Plus Network if you are not? Dr. Brinson requires you to upload your insurance card on ZocDoc to make an appointment. Why was I not called to be told he does not accept my insurance after I uploaded my insurance card into Dr. Brinsson's ZOCDOC accounts. Why would your office not call me to let me know he is not in the office on Monday and not to make the trip?!?!?!?! Why would you not call me to let me know he does not take my insurance and he is not in the office? I was in the system, no one knew to call me and tell me not to come, or at the very least, reschedule? What terrible service by ZocDoc and the Doctor's Incompetent staff. I cannot say if the Doctor is good or bad, but his staff is bad.
