What is the best way to fight an insurance denial?

I had to have a procedure done last week. If I hadn't had it I would have ended up having a larger more complicated surgery that would have possibly left me with the inability to bear children.

If I hadn't had it I would have ended up having a larger more complicated surgery that would have possibly left me with the inability to bear children. My insurance company denied payment on the procedure because they said it wasn't necessary because I wasn't going to die if I didn't have it. I have three doctors who think otherwise. While I wouldn't have died, there would have been serious problems if I hadn't had it. What's the best way to convince the insurance company to pay for the surgery? They said I have 60 days to appeal.
