Help! I'm trying to code IV administration of Remicade for Rheumatoid Arthritis. I was told to use v5811 which is Encounter for antineoplastic chemotherapy. Should I use this code even if the drug is not a chemotherapeutic agen, or shoud it be coded as 9928 which is inj. or infusion of biological response modifier (BMR) as an antineoplastic agent? Thanks to anyone that can help me.
