Blue Cross Blue Shield of Alabama

I need help, I am interested in having the Lap-band WLS, but my insurance (Blue Cross Blue Shield of Alabama) does not cover it, citing that it is investigational. Before I can proceed with appealing the insurance (because I don't have an official appeal letter I was denied at the precert stage) I need to find out if ANYONE has BCBS of Alabama and has undergone the lap-band. So if someone out there has please let me know!! I anyone needs more information on my situation, please feel free to email me or post. Thank you in advance for looking and helping. Chastity
