I'm going to attend my seminar in Jan 2013. I weigh 250 pds. Have been dieting and changed my life style, nothing works. I have BCN Advantage Ins. My older sister had the sleeve done last summer. Does anyone know if you still have to go through a 6 mo diet plan in order to get the surgery? My sister had Hap and did not have to go through that. With my other insurance I had to go to weight loss clinic for 6 mo. And they refused to pay for the surgery because I fell short 3 pounds. I lost 48 pds. Now I have gained half of it back. I need help.
