I am in the same situation. My surgery is scheduled for 10/29 but still do not have insurance approval. I start my one week pre-op diet tomorrow and I have my pre-op appointment on Wednesday with my surgeon and have my time scheduled off of work. It seems strange to continue through all the final steps without even know if I am approved but the woman who handles the precertification continues to tell me not to worry and seems to be the way they always do it. She seems quite knowledgeable and does not have any concerns the surgery being approved. I am glad she is so calm because I am becoming increasingly anxious by the day regarding the approval. They cut everything so close. I am so ready to have this surgery and would love to know it was approved. Good Luck! I'll keep my fingers crossed for both of us!!
