HCPCS Level II code S9376 represents a per diem charge for home infusion hydration therapy administrative and professional services covering more than two liters but no more than three liters per day, including care coordination and necessary supplies and equipment. This code matters nationally as home infusion expands access to outpatient hydration management, reduces inpatient utilization for appropriate patients, and affects how payers reimburse bundled administrative and pharmacy oversight separate from drug and nursing charges. Key payers discussed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.

Readers will learn what S9376 covers clinically and operationally, which typical sites of service it applies to, and which components are billed separately. The publication outlines national benchmarks and policy context for home infusion per diem codes, highlights payer coverage considerations and common modifier usage, and summarizes implications for billing workflows and care coordination. Where input data was not provided, the report indicates missing items such as associated taxonomies, ICD-10 mappings, and related codes. This concise overview is intended for billing managers, pharmacy providers, and policy stakeholders seeking a clear description of S9376 and its role in home infusion services.
