Bcbs Ppo Nc

My plan will cover the band after several conditions are met, one being that you have to have weight histories for the last 5 years and have 4 of those years obese. I do not have any comorbidies but my curent BMI is greater than 40. I had surgery 4.5 years ago and really packed on the pounds (201 to 231 in less than 4 months). My question is, last June I was 231 ish which is not quite a BMI of 40. Within the next few months was over 40. Will they get that technical down to the month when we are talking four years? Also, I'm a teacher and actually work out in the summer. If I lose weight (which I would like to in preperation for surgery) and fall below 240 before my end of June consult, will I still qualify?

I also have bcbs and I found out today that I have to have a list of medically supervised weight loss regimens for the last 24 months. Anyone else have this as a prerequisite and what exactly does this mean
