Emblemhealth/multiplan Epo

hello! im looking into getting my lap band done...first time about two years ago while living in ny I completed the sixth month diet,psych eval,nutrition everything! then two weeks before my surgery the surgeon that took my insurance left for personal reasons so..no surgery. NOW living in AZ I really want to the ball moving. I have called emblem so many times but cant get a straight answer. My question for anyone that could possibly have an answer is in NY my insurance is EMBLEM HEALTH and on the back it says " outside of ny national network is MULTIPLAN" im not sure what to do....hopefully someone is in the same boat as me or knows what insurance I should tell my surgeon I have. btw i am 100 lbs over weight and my bmi is 52. thanks!
