I have Aetna, I had to do an upper GI, blood work, an EKG, a letter from my PCP recommending the surgery, a psych eval and 2 years of pcp notes from visits with at least 6 months of weight loss attempts with 3 of those being consecutive months.
Aetna stated it takes them 2 weeks when all documentation is provided to approve.
Thanks to my surgeon's office it took me 2 and a half months to get approved. They did not follow what Aetna asked for and dropped the ball in a major way!
