The front office was incompetent. They cannot tell you what the charges are and then just expect you to pay them. I asked for a breakdown of the billing on 4 different occasions and never received a clear answer. I asked them to call me and they ignore it. Just got a bill.
I have Humana insurance. Sunwest has agreed on a contracted amount for services with Humana, yet they bill you whatever they see fit and you will be responsible for the difference.
When you go into their office make sure you understand what their agreement is with your insurance company and make sure they tell you what they are billing you for; because they will not (or cannot) tell you. It is a mystery until you get the bill.
The dental service was fine, but the billing experience was terrible. I am being asked to pay much more than expected. VERY DISAPPOINTING.
