Quite awful customer service. I went to Dr. Harrison's office in Oct'18 for getting a assessment for Apico procedure. I found out treatment options. Then just to be sure that my insurance would cover all the costs, I requested that they get a pre-approval. I was told by the doctor and the front office person that they can do that. I was told that they will call me as soon as insurance gets back to them. 4 weeks passed and I didnt hear anything from them. So I call the Drs' office. First, the front desk lady says that I left you a VM, didnt you get it? I am like, I didnt. I asked when was did you leave voicemail and what did the insurance say. Then she is like hold-on. After couple mins she says the insurance never got back to her. She is like let me call them. I am like Ok, I let it slide that she initially said, I left you a VM. Two days pass and I dont hear from the Drs office. So I decide to call my insurance company. They say they had sent a letter to Dr. Harrison's office on 2nd Nov 2018 saying that they had approved the apico but denied the graft. I asked them why the graft was denied and how can it be approved. Insurance rep. said the doctor's office needs to include a narrative as to why graft is needed and then they will approve it. So I call Drs office, the front desk lady says that she was very busy and hasnt been able to reach my insurance. I give her benefit of doubt and share with her what insurance told me. I tell her that they had sent a letter on 2nd Nov to them and insurance needs a narrative for the graft. She is like ok, we will send them the narrative. 4 more weeks pass, now it is middle of Jan 2019. No response from Dr Harrison's office. So I call my insurance again, the insurance rep. checks file and reminds me about the letter they sent on Nov 2nd and tells that they havent received the narrative for graft from Dr. Harrison's office. At this point I am quite upset. I felt that the front desk person of Dr. Harrison is slacking and decide to inform Dr. Harrison. I call the front desk, the lady immediately asks me whether I have heard about approval from insurance. I figure it would be pointless to even tell her that she hasnt done what she had promised. I just say politely, that I have a quick question want to talk to Dr. Harrison for 1 min. She said, he is busy and will leave a note for him. Three more days, and three more polite follow-ups to Dr. Harrison. On the fourth day, a different front desk lady calls, she says that Dr. Harrison would want me to make an appointment and come to office if I have a question. I am like, it will be quick 1 min over the phone as opposed to me spending one hour of my time. I am like, no thank you. Hence I am writing here to share my experience. I will find another dental surgeon for the apico procedure. 4 months lost!
