HCPCS Level II code B4150 represents a nutritionally complete enteral formula with intact proteins, fats, carbohydrates, vitamins and minerals, intended for administration via an enteral feeding tube. Units are billed by caloric content, with 100 calories equaling one unit. This code matters nationally because enteral nutrition is a core component of care for patients with impaired oral intake, chronic conditions requiring long-term tube feeding, and post-acute recovery, and it drives durable supply and coverage decisions across payer contracts.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for enteral formula use, typical sites of service where B4150 is billed, and what to expect in payer coverage patterns. The publication provides benchmarks for utilization and reimbursement frameworks, highlights relevant policy considerations affecting coverage of enteral nutrition supplies, and situates B4150 within common billing workflows. Data not available in the input will be noted where applicable.
