My Dr. doesn't believe in WLS!!!!
I would say look for another doctor---or try to educate the one you have if you want to stay there. If you want to go straight to a WLS doctor and have your insurance pay for it, then you need to check to see if your insurance requires a referral or not. I actually called the surgeon I knew would be covered by my insurance and asked them for some names of PCPs that were WLS friendly in my area. You might want to get on the Tenn (?) board and insurance board to see how it is to deal with BCBS/Tn
Good luck!
