Summary & Overview
HCPCS S9367: Home TPN Per Diem, 2–3 Liters/Day
Headline: HCPCS Level II code S9367 defines per diem home infusion TPN for 2–3 liters daily
Lead: HCPCS Level II code S9367 covers comprehensive per diem services for home total parenteral nutrition (TPN) when patients require more than two but no more than three liters per day. The code bundles administrative and professional pharmacy services, care coordination, and standard TPN supplies and equipment; separately reportable items include nonstandard drugs and nursing visits.
What this represents and why it matters: Home infusion TPN supports medically complex patients who require long-term intravenous nutrition outside acute care. A clear national coding designation like S9367 standardizes billing for bundled home infusion services, which affects care coordination, provider reimbursement workflows, and payers' coverage policies.
Key payers covered: Analysis addresses national payers including Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
What readers will learn: The publication provides benchmarks and coding guidance context for HCPCS Level II code S9367, summarizes payer coverage patterns and policy considerations, and explains the clinical and operational scope of the service (per diem home TPN for 2–3 L/day).

Clinical & Coding Specifications
Clinical Context
A 62-year-old patient with short bowel syndrome secondary to multiple small bowel resections requires long-term home total parenteral nutrition (TPN). The patient receives an established home infusion therapy plan with a daily TPN volume of 2.5 liters. A specialty pharmacy coordinates formulation of a standard TPN formula including lipids and amino acid solutions; parenteral electrolytes and select additive drugs are included as ordered. A pharmacist provides professional services for medication preparation and oversight, and an infusion company supplies the tubing, infusion pump, and disposables. Nursing visits for catheter care and infusion setup are scheduled separately and billed under nursing visit codes. Clinical workflow: physician documents indication and TPN orders and certifies home infusion; pharmacy receives orders, compounds or dispenses per protocol, and communicates administration instructions; home infusion provider arranges delivery and equipment setup; patient or caregiver performs or supervises daily infusion per training; ongoing care coordination occurs between physician, home infusion pharmacy, and home health nurses to monitor weight, labs, electrolytes, and catheter-related complications. Billing uses per diem submission for the TPN administrative and professional pharmacy services and supplies under S9367, with separate claims for nursing visits and any infused medications billed outside the standard formula.
