Anyone with Anthem Blue Cross PPO?

Does anyone have anthem blue Cross ppo insurance? If so what does the insurance require before wls? 

I have the same ins company and when I called them they told me it's not covered under my plan now I don't know what to do

I have Anthem BCBS of IL. I think the state/region matters. Ours covers bariatrics. All we have to show is that we made an attempt under a doctor's supervision (typically it's 6 months of monthly visits and weigh-ins) and a letter of necessity.

Pretty sure Anthem is the trade name for California BCBS. Their policy statement is here, but it's not too clear on whether or not you need a physician supervised diet.
