hey I had a private big ins. co. deny claim for redlabs/vip cfs complete panel (looking at rnase, natural killer cells etc) and it was orderd by a physician in large university clinic setting, so a mainstream respected setting. They delayed their decision by like 8 months and then called it "experimental" even though they had inexplicably paid for a cheaper genova lab test earlier in the year which would certainly be "experimental" by ins. co. standards too, its just a big bill they don't want to pay so they find loopholes. Any advice on how to appeal successfully?
