all I can say is I never had 1 problem with Aetna. but they have so many different policies. have you checked out their Clinical Policy Bulletin for Obesity Surgery? If not go to Aetna.com up in the top right hand corner there is search box, type in 0157 this will give you all the criteria that they are going by to make there decision. it helped me navigate the system and understand why I had to go through what I did before surgery was even approved. my surgery was submitted on monday and was approved by wednesday but i did everything they wanted(if your surgeon is part of a weight management center I think it is easier because they know what your insurance needs/wants) & I had 2 comorbidities which I don't have anymore. I had surgery 4/13/10 @ was 230lbs I am now at 201lbs. hope this helps.
