As of Feb. this year, Anthem did away with any supervised weight loss requirement. I had a friend speed up her surgery by 4 months because of that. Other, than that, you just have to do the intial consul, psych eval., and proof of 3 years of medical history. That is thru St. Vincents Bariatric. I've heard that IU makes you do more things. But, with St. V, there is no required pre-surgery weight loss or diet. Anthem is probably one of the easiet now. Thank God!!! I wish that it had been that easy when I was going thru the process last year. I had to do 6 months of supervised WL.
