Need help find insurance..

Hey guys, really need some help finding  insurance that well cover gastric bypass surgery. I do have Florida Blue from Healthgov.com website but those plans do not cover gastric bypass surgery. That's what they say when I call the office and to find other Insurance. I'm 6'1, 550 lbs and really do need help. If anyone has any numbers I could call or website I can look up it would be great. TY
