Question: When I use a chemo admin code for a drug that isn't chemo (such as Remicade or IVIG), should I still report V58.11? Washington Subscriber Answer: No. You should report V58.11 (Encounter for antineoplastic chemotherapy) only for patients receiving chemotherapy. If you report a chemotherapy code for antineoplastic immunotherapy, you may report V58.12 (Encounter for antineoplastic immunotherapy) instead. If you use a chemotherapy code for a substance that is not antineoplastic, such as Remicade, you should not use either V58.11 or V58.12.
