I have an insurance payer that is specifically requesting that we add "zz" before the taxonomy code for our 2ndary paper claims-which is how I guess how they identify these claims once they are scanned & process them. I was handwriting them in, but now I am having increasingly continuous issues with these claims and the payer wants them typed in. When I tried going into the payer rules, to specifically do this for this payer, it does not let me b/c it only allows up to 10 digits. I really need additional space added to this field in order to accommodate this "special" request from this payer. I would be truly grateful if you could help me with this particular request.
