CPT Code Overview
CPT 96415 describes chemotherapy administration using an intravenous infusion technique for each additional hour, billed in addition to the primary infusion code. This add‑on code applies when an infusion extends beyond the time covered by the initial hour and is intended for administration of chemotherapy or other highly complex drugs or biologic agents.
Service Type: Injection and Intravenous Infusion Chemotherapy and Other Highly Complex Drug or Highly Complex Biologic Agent Administration
Typical Site of Service: Infusion center or outpatient facility, commonly submitted alongside the initial infusion code CPT 96413 when treatment duration exceeds the first hour.
Clinical & Coding Specifications
Clinical Context
A 62-year-old patient with metastatic colon cancer (diagnosis C18.9) receives outpatient intravenous chemotherapy in an infusion center. The oncology nurse initiates the primary infusion coded as 96413 for the first hour of a chemotherapy agent. The patient’s regimen requires a prolonged infusion, so after the initial hour the nurse documents continued infusion time in one-hour increments. Each additional hour beyond the first hour is reported using the add-on code 96415. The treatment encounter includes medication preparation, IV access verification, infusion rate monitoring, vital signs, and documentation of any infusion-related reactions. Reimbursement submission commonly pairs 96413 (initial hour) with one or more units of 96415 to reflect the extended infusion time.
