My medical oncologist said that while they are a CCC, they are not set up for HPV testing of the biopsy. He looked into getting it done elsewhere but at least in the DC area, Blue Cross Blue Shield doesn't pay for such testing post biopsy. I had asked to get it done after reading the info here. Sort of moot at this point, since I had maximum treatment anyway although it would be reassuring in light of indications that HPV base of tongue cancer is more amenable to having a CPR (complete pathological response) go with the CCR (complete clinical response) that I got so far.
