What 96420 covers
96420 describes chemotherapy delivered directly into an artery using a push technique. It may be used when an oncology team administers a drug through an arterial catheter for regional treatment, such as chemotherapy directed to the liver through its arterial supply. The service is the drug administration, not the catheter placement. It is distinct from an infusion, in which medication is delivered over time.
Select the code based on the arterial route and push method documented for the encounter. The record should identify the drug, the route of administration, and that it was administered by push; report the drug separately when applicable. Medicare treats this as an incident-to service: it may be billed only when performed under physician supervision.
