Gary Viscio!!!

Okay so my insurance denied me first off because my surgeon was out of network then they said they won't do it until I'm 21...tricky thing though is I will not be covered any longer once I'm 21 since my mother is covering me. I'm in college but I'm only 19. My surgeon told me I deserve to have this and I agree with him! Please help me get covered? What do you think I should do?

get something in writing.  the age is normally 18.  They could be stalling or just plain wrong when you call.
