HELP!!

I have a friend who desparately needs this surgery. She was ok'd by her doctors, had the psych eval and the whole ball of wax and then was denied by her insurance. They say they do not cover it and would not cover any problems afterwards. I believe she said her company is Health Traditions. Does anyone have any ideas of what she can do to get them to let her have this very much medically necessary surgery? Thanks. Michelle Appel
