Clinical & Coding Specifications
Clinical Context
A 68-year-old patient with metastatic colorectal cancer receives ongoing home infusion therapy through a single-lumen central venous catheter for intermittent chemotherapy-related supportive medications (e.g., hydration, electrolyte replacement, or symptomatic infusions) and catheter maintenance. A home infusion provider delivers daily per-diem administrative services that include catheter care and maintenance, dressing changes, flushing protocols, supply provision, professional pharmacy oversight, and care coordination. Drugs administered via the catheter (chemotherapeutic agents, IV antibiotics, or IV fluids) and any nursing visits for hands-on infusion or assessment are billed separately. Typical workflow: referral from oncology to a home infusion pharmacy; initial pharmacist review and supply setup; scheduling of periodic home nursing visits as needed; daily per-diem billing under S5498 for catheter care/maintenance and supply provision; separate billing for medication HCPCS/CPT and nursing service codes; ongoing documentation of catheter site condition, dressing changes, flushes, complications, and communication with the ordering clinician.
