Clinical & Coding Specifications
Clinical Context
A typical patient for B9004 is an adult receiving home parenteral nutrition (HPN) after intestinal failure. Example: a 58-year-old male with short bowel syndrome following extensive bowel resection is discharged from the acute care hospital to home with a central venous catheter and a portable parenteral nutrition infusion pump. The clinical workflow includes: outpatient or home-health clinician education on pump operation and troubleshooting; initial pump programming by a trained clinician or durable medical equipment (DME) supplier to deliver prescribed infusion rates and volumes; regular nursing visits for dressing changes, catheter care, and assessment of infusion tolerance; periodic clinic or home-lab monitoring of electrolytes, liver function, and nutrition status; and device exchanges or returns at the end of the rental period. The service is provided in the home or other ambulatory non-facility setting and supports continuous or intermittent infusion of parenteral nutrition formulations prescribed by the treating physician.
