i just called and they do take medicare! Dr. Rey is seeing all of Dr. Klimas's patients now as Dr. Klimas is working on setting up a program to teach other docs about CFS (so great).
I have BC/BS but not of Florida. I just called my insurance and they would cover it as in in-network visit - wow - amazing! (If you have BC/BS, please check in to your own situation, because I know they have a lot of different groups).
