Summary & Overview
HCPCS Level II S9348: Home Infusion, Sympathomimetic/Inotropic Agent Per Diem
HCPCS Level II code S9348 designates a per diem service for home infusion therapy involving sympathomimetic or inotropic agents (for example, dobutamine), bundled to include administrative services, professional pharmacy services, care coordination, and necessary supplies and equipment. This code is distinct from drug and nursing service lines, which are billed separately. Nationally, the code matters because home infusion of inotropic agents is a high-acuity, resource-intensive service that intersects pharmacy management, durable medical equipment, and coordinated home nursing care.
Key payers in scope include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will learn how S9348 is positioned within home infusion service lines, how it separates administrative and professional pharmacy components from drug and nursing charges, and the typical sites and clinical contexts for use. The publication provides benchmarks and policy-relevant context for reimbursement and claims processing, plus practical guidance on documentation and billing workflow considerations. Data not available in the input is noted where applicable, and readers are directed to payer-specific policies for coverage criteria and prior authorization requirements.

Clinical & Coding Specifications
Clinical Context
A 72-year-old patient with chronic ischemic cardiomyopathy and symptomatic low-output heart failure is discharged from the hospital to receive home infusion therapy for continuous dobutamine to improve cardiac output and organ perfusion. The home health pharmacy coordinates medication preparation, delivery of infusion pumps and tubing, and provides professional pharmacy services including dosing verification and care coordination. A visiting nurse performs line assessment, vital signs, and pump setup; nursing visits and the dobutamine drug are billed separately. The per diem administrative service described by S9348 covers home infusion program management, supplies and equipment provided by the home infusion vendor, phone-based clinical oversight, and coordination with the prescribing cardiologist and primary care provider.
