appealing bcbs of delaware

I was denied VSG by BCBS of Delaware as they only cover it for those with BMI of 50 or above and those with BMI 50 that are going to get DS after the sleeve. Of course I am covered to get lapband or RNY which neither is something I want.
My current bmi at 43. Does anyone have any advice on what I should do,say or include in my appeal letter to try and reverse this decision?

There are a few people that have appeal letters on their page. If you haven't already post this on the VSG forum to see if someone can help you. I know of a few people that have appeal letters.
Also, google WLS appeal letters, there are few that come up.

I am actually about to post on the VSG forum to ask if any one had any appeal letter statistics on performing surgery on people with a BMI under 50.

Hope this helps.
