HCPCS Level II code S9340 identifies per diem administrative services for home-based enteral nutrition, including professional pharmacy services, care coordination, and all necessary supplies and equipment (with enteral formula and nursing visits billed separately). This code matters nationally as home enteral nutrition is an essential chronic-care service that involves multidisciplinary coordination and supply management; clear coding supports appropriate payment for non-clinical, administrative elements of home nutrition therapy. Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.

Readers will find an overview of the service the code represents, guidance on expected site of service and service type, and a framework for understanding where S9340 fits within home infusion and enteral nutrition billing. The publication provides benchmarking context and policy-relevant considerations for payers and plan administrators, explains which components are bundled versus billed separately (noting enteral formula and nursing visits are excluded from this per diem), and highlights common modifiers used with this code. Data not available in the input on specific payer rates, taxonomies, ICD-10 pairings, and related codes is noted.
