BCBS MA PPO Plan

So I was looking at some of the posts last night and I saw people who had BCBS in other states who were getting denied for the surgery and I TOTALLY freaked out!! So I called BCBS and this is what I was told that they don't cover Sleeve Gastrectomy because it still "Investigational", and the the lady is like but we cover Lap Band! I am so crushed and don't know what to do at this point do I submit my paper work and have them deny me and then appeal it or do I go with the lap band that I know is going to be covered!!!!!!!!!!
