I have BCBS also, and you have to read the requirements very carefully. They basically require 6 months of monitored weight loss plan, documented every month by the PCP. Failure to be able to lose 10% of body weight, in spite of the supervised program is qualifying for surgery. When I first read the requirements, I thought it said I had to LOSE 10% to qualify - to demonstrate compliance with the program, but that;s not what it really says. I think I stayed about the same weight. I was tipping the 40 BMI, but what really helped me was getting a sleep apnea diagnosis, which lowered the qualifying BMI. BCBS is tricky. Just read those requirements over and over until you understand them thoroughly. As long as your PCP also documents all your weight loss attempts very thoroughly, you should not have a problem. My PCP did an amazing job. She knew how to "play the game" and told me she had never had any of her patients denied WLS.
