Body Conturing turned down from Insurance- need help

Hi I recently applied to have my insurance pay for my Pannus to be removed but I was turned down.  Does anyone have any idea on how to get them to cover it?  I have lost over 160 pounds and I hate having this thing on my stomach.  They said that I did not have any visible marks under my stomach.  Does anyone know how to get infections under there?  They said that might help me get my surgery.  

Thank you,

Jamie

My insurance paid for mine, I had skin issues documented by my doc.
