I have AHCCCS Mercy Care as well. You can not gain ANY weight on the six month weight loss diet otherwise they will deny your claim. I gained 6.6 lbs during two months and then at the end I lost 14 lbs from my start weight to my end weight (20 lbs if you count that I also lost the 6.6 lbs I gained). I was denied for gaining weight during the plan. Don't let your weight ever creep up over the starting weight or you will have to start over. Right now I am going back to my highest weight during the 6 months and using that as my starting point so I will only have to do 3 visits more before we can resubmit it for surgery.
