ok , heres what i would do , first of all, our database here lists literally DOZENS of bariatric surgeons ,
you could, collect some phone numbers and call around , thats one way, or go to the find peers section of the site, look up your state, and page through the post ops, checkng each ones insurance info , this will be tedious, i hope someone can offer a quicker answer, but i know for a fact , if its medically nessecary, you can have the surgery, its just the issue of finding a dr who will accept it....
good luck , let me know how it goes!
