HCPCS Level II code B4159 covers a nutritionally complete, soy-based enteral formula formulated for pediatric patients and intended for administration via enteral feeding tube. The product includes intact proteins, fats, carbohydrates, vitamins and minerals, and may contain fiber and/or iron. Units are billed as 1 unit per 100 calories.

This code matters nationally because pediatric enteral nutrition is a persistent clinical need across home health, pediatric specialty clinics, and outpatient infusion services; standardized HCPCS coding supports accurate claim submission, product tracking, and reimbursement for durable medical supply vendors and clinicians managing long-term tube feeding. Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.

Readers will learn the clinical scope of the code, expected service settings, and the kinds of metrics and policy context typically associated with enteral nutrition codes — such as unit definitions, place-of-service implications, and how this code fits into pediatric nutrition management. Data not available in the input includes associated taxonomies, ICD-10 diagnosis pairings, and related codes; those items are noted as unavailable. The publication provides benchmarks, payment context, and coding considerations relevant to supply management and billing workflows for pediatric enteral formula.
