Summary & Overview
CPT 96417: Add-On Intravenous Infusion for Sequential Chemotherapy
Headline: CPT 96417: Add‑On Intravenous Infusion for Sequential Chemotherapy
Lead: CPT 96417 identifies an add‑on procedure for continued intravenous infusion when a different chemotherapy drug is administered following a primary chemotherapy dose. The code captures sequential infusion events during a single treatment encounter and is commonly used in oncology infusion settings.
CPT 96417 represents a focused billing descriptor for highly complex drug or biologic infusion that follows an initial chemotherapy administration. Nationally, accurate use of this add‑on code matters for distinguishing multiple sequential infusions during one visit, ensuring clinical events are documented and billed distinctly from primary infusion codes. The code is relevant across outpatient infusion centers, hospital outpatient clinics, and physician offices where multi‑drug chemotherapy regimens are delivered.
Key payers covered in this overview include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will learn the clinical and billing context for CPT 96417, how it relates to initial and additional infusion services, and the typical care settings where it applies. The publication provides benchmarks and policy context for coding practice, clarifies common use cases, and summarizes cross‑payer considerations and coverage patterns. Data not available in the input for payer-specific reimbursement rates or state-specific policy variations.
CPT Code Overview
CPT 96417 describes an add-on chemotherapy administration procedure in which a provider continues administration of a chemotherapy drug into a vein using an infusion technique. This code is used to report the administration of a different chemotherapy drug delivered via intravenous infusion following the administration of a primary dose of chemotherapy.
Service type: Chemotherapy administration – add-on infusion (Medicine services and procedures)
Typical site of service: Infusion center or outpatient hospital clinic (typically POS 22), or office (POS 11)
Clinical & Coding Specifications
Clinical Context
A 62-year-old patient with metastatic colon cancer (C18.9) presents to an outpatient infusion center (POS 22) for scheduled chemotherapy. The oncology team administers an initial intravenous infusion of a chemotherapy agent using code 96413. Following completion of the primary drug infusion, the provider continues administration of a second, different chemotherapy agent via intravenous infusion and documents the continuation as an add-on administration using 96417. The encounter occurs in an infusion center staffed by an oncology nurse practitioner (taxonomy 163WX0200X) under the oversight of a medical oncologist (taxonomy 207RX0202X). The facility documents start and stop times, drugs administered, and sequencing of doses to support reporting of the primary infusion and the subsequent add-on infusion.
