Clinical & Coding Specifications
Clinical Context
A typical patient is an adult receiving home infusion therapy who requires ongoing central venous catheter (CVC) or peripherally inserted central catheter (PICC) maintenance and coordination but does not require a separately billable drug infusion or discrete nursing procedures under this per diem. For example, a 68-year-old patient with short bowel syndrome established on home parenteral nutrition presents for routine home infusion program enrollment and catheter care. The home infusion provider performs catheter dressing changes, catheter patency assessment, flushes per protocol, supplies replacement catheter caps and securement devices, documents care in the clinical record, and provides care coordination with the patient’s physician and durable medical equipment supplier. Pharmacy staff complete administrative services including medication reconciliation, sterile supply preparation, patient/caregiver education on catheter care and infection prevention, and scheduling of nursing visits that are billed separately. The clinical workflow includes initial intake and verification, home visit scheduling (or telehealth triage), catheter assessment and maintenance during visits, supply management, documentation of catheter integrity and any complications, and communication of findings with the ordering clinician for follow-up or escalation if infection or malfunction is suspected.
