As far as I know , no insurance carriers ask methodology of  results, they 
treat breast cancer(tamoxifen) based on  all our various methods and clones, 
does this not set a precedent? Insurance carriers still allow the pathologist 
to render diagnosis, based on their judgement and all our different systems. 
How dare any one company place fear into us? HCFA forms only ask for 
procedure codes and diagnosis, no place on form as of yet for company of 
antibody or detection. We are all using same code to bill for IHC right? How 
would any company know anything else?
