My doctors office told me about how hard it is to get BCBS Illinois to approve. She told me I would be denied immediately and then she would call and have a peer to peer talk she has hopes that will work. Nothing has been submitted yet as she is trying to collect as much as possible on my last 5 years of medical history. I have a BMI of 38 so that is why she said it will be hard but since there is a will there is a way. I guess this is one of the hardest insurance there is to get approved. Thats my luck!
