I've recently gone to the very first informational class, and during it the facilitator said that members who have Aetna plans have a much more strict criteria during the 6 month pre-op phase. One being they cannot gain any weight, or they will be denied immediately. She had one patient gain one pound, and was denied the surgery (thankfully she was able to fight that and was able to get her surgery approved). My vote is for anthem as well.
