Does anyone know what Cigna requires to be approved for the sleeve. I have a band and would like it out and am thinking about the sleeve. I have gotten my first denial letter and they said they wont take out my band because the is nothing technically wrong with it. Apparently my suffering and new hiatal hernia from the band doesn't seem to matter. I was going to file an appeal, however, I wanted to see what I need to give them to get this approved.
