We have an allergist that is using 96401 to bill for the administration of Xolair with the thinking that it is a chemotherapy-type drug. He is getting paid for it at present, but I am concerned that he'll be subject to recoupment under review. Is anyone else using 96401? Our curent recomendation is to use 90772 with modifier 76 for repeat injections. I have also read on this forum that others bill 90772-59 since the injections are done at multiple sites. Also, are others billing for the preparation of the therapy 95144?
