Hi Stacy,
I have the same insurance. I applied for the sleeve in 8/10. I was approved right away for the lap band and the bypass but denied the sleeve. I wrote an appeal letter and addressed each reason they gave for denying me. I sent it in 10/10. They claimed never to have received it so I resubmitted and sent it in registered mail in 12/10. I also included letters from all my doctors stating why this was the right surgery for me. I was approved in 1/11 and just had my surgery 2/15/11. My best advice is when you apply, give them as many reasons as possible why this is the right surgery for you. Then if you do get denied, don't just roll over. Fight for your right to pick what is best for you. Good luck!
Lisa
PS-I would be glad to share my appeal letter if it would help anyone.
