I have aetna and this Dr is an in network provider. He still said he won't do a pre certification and to pay cash up front. I was in so much pain I had no choice. My insurance said it payed 100% of the bone graft and extracttion. This office even after my insurance company paid him in full refused to reimburse me. It is going on 6 months and I still haven't received my money for the fees I payed up front. The Dr called me a baby and the office manager Nancy hung up on me and my insurance company several times.
