My rhem. ordered tests from IGenex. My insurance co. denied the request, stating the regular lab, Lab Corp/Quest could perform the tests just as well as IGenex. My doc. said no. I called IGenex and asked for help, since I am, no doubt, the first person to be in this situation. The person answering their phone was incredibly rude and told me " It is not our place to convince the insurance company of anything". Guess I'll just hang in their and enjoy my head to toe burning pain for another decade or two.
