Well I have aetna and I can only tell you the hoops I had to jump through to get my band. (note: My bmi was well over 50 and the doctors scales would not get my wieght because they only go up to 350 or something so no documentation all just guessing) Well I pulled my charts from my 2 last pcp and then i did a sleep study which showed i have a slight case of sleep apnea, I also had high blood pressure and asthma,I went to see a cardioligist and did a series of tests, blood work, chest x-ray, ekg, physical, phsyc eval, nutrional eval and monitoring for 3 months with supervised diet and excersise, and then the eval from my WLS and that was it I started the whole thing on the 27th of july 2008 and was banded 3 months to the date on 10/27/08 I never even really had any issues I just did all the test the WLS told me to do and they did the rest. I do know that my WLS did spice up the eval he submitted to Aetna. Once submitted it took less then a week to get my responce. I dont know if all that info will help but that is what I had to do :thumbup: Have a great day and GOOD LUCK
