I have blue cross blue shield of Alabama. I had to go through 8 months of monthly weigh ins with my doctor, labwork to include liver enzymes and h. Pylori test to make sure you don't have a bacteria that causes ulcers in your stomach, sleep study to make sure i didnt have sleep apnea, physical therapy evaluation to see if I can exercise, psychological consult just to make sure I'm not crazy or if there is some underlying reason that I am obese, diet class, and I had to show them my last 3 year weights. Oh, if you are over 40 you have to have your pap and mammo up to date and if you are over 50 you have to have a colonoscopy. Thank goodness i'm not over 50. My Lapband office did all the insurance approval for the lapband procedure.
Hope this helps. Good luck
