My surgeon, who is very knowledgeable about insurance, says the Aetna requirement for a 6-month supervised diet can be satisfied if you have been on a 3-month medically supervised diet (3 consecutive months) with the past two years, and 3 months "followup" months. So after 3 months, I am submitting to Aetna this week, because my PCP put me on a diet over a year ago and I saw him for 4 consecutive months. I also had to see the psychologist and a dietician, and come up with the 5-year history, which took some legwork to come up with one of the years. I had a "missing" year and a retired doctor for that year and I had to track the doctor down to find my records. She is meeting me tomorrow to give me a notarized statement for that year. Let's hope that works!
