Large septum perforation: Need a specialist that takes Tricare Standard and can work on large septum perforation.

I have had it for many years but after moving from WA to a dry climate in AZ, the hole grew. I have seen several ENT's whom have said they don't feel comfortable fixing it and have all refereed me to the same 2 ENT's that specialize in larger septum perforations. They do not accept my insurance and I cannot pay $22,000. I have anxiety because I worry about it collapsing, breathing is difficult through my nose, it hurts, and sometimes bleeds. I am willing to travel anywhere in the USA.
