Where can I find insurance covered cosmetic surgery after extreme weight loss?

After losing 120+ pounds I have a lot of hanging skin and I want to have it removed. I've had 2 consultations by a cosmetic surgeon that did a reduction for me some years ago (paid for at my expense) but the request was denied. I have since changed insurance providers but still haven't had much luck in getting pre-approved this go around. Does anybody know of any doctors or information that might be able to ist me with getting this skin removed?
