BCBS of NC-Anyone have success with an appeal?

Hello Room, I have just finished a 5 page appeal letter to BCBS of NC. Has anyone EVER appealed, and won? I doubt it, since they have a written exclusion for lap band. Ive written them not only a statement proving its a medical necessity, but also I pointed out where it was endorsed by the FDA in 2001. I included alllllll the "buzz" you hear on this website, but Im not optimistic. The truth is, you hear of alllllll these people appealing insurance companies, and winning. But is that the norm, or just the EXCEPTION? Maybe Im just anxious, but Ive learned this site is full of opinions, and ideals. I just hope its real. I appreciate all the help and guidance you guys have provided me over the long haul. I hope to join the bandster nation soon. Steve
