Clinical & Coding Specifications
Clinical Context
A 62-year-old patient with metastatic colorectal cancer is discharged from an oncology infusion center for home-based continuous 24-hour chemotherapy infusion via an elastomeric pump. The patient has a tunneled central venous catheter placed during an inpatient admission and a multidisciplinary home infusion plan is established. The home infusion provider pharmacist coordinates medication compounding, dosing schedule, and delivery of supplies; a registered nurse performs initial home setup, catheter and infusion site education, and periodic nursing visits for assessment and line care; the oncology physician provides remote medical oversight and dose adjustments. Administrative and professional pharmacy services include prior authorization support, clinical monitoring, medication reconciliation, electronic documentation, and supply management. Drugs (chemotherapy agents) and nursing visits are billed separately; S9330 covers the per diem administrative, pharmacy, care coordination, and equipment components of continuous (24+ hour) home chemotherapy infusion therapy.
