I am needing something in writting about how and when to bill for skin neoplasm. My practice likes to use code 238.2 "Neoplasm of uncertain behavior" when removing a skin lesion and want me to bill it that way before the pathology report is back with the actual diagnosis. My problem with this is that the stigma of "Neoplasm" of any kind is not supposed to be given to a patient unless it is actually a neoplasm. My practice likes to then go back to the original claim and change the diagnosis once the pathology report is in and send corrected claims with the new diagnosis code. I think this is incorrect coding practice but don't know where to find it in writing to give to my doc. Any help would be greatly appreciated. Thanks Missy
