Summary & Overview
HCPCS B4150: Enteral Formula, Nutritionally Complete with Intact Nutrients
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.

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with impaired oral intake due to neurologic dysphagia following stroke, progressive neurodegenerative disease (for example, amyotrophic lateral sclerosis), or head and neck cancer with obstructed swallowing. The patient has an enteral feeding tube (nasogastric, gastrostomy, or jejunostomy) in place and requires ongoing nutritionally complete formula delivered via the tube. Orders are written by the treating physician or advanced practice provider specifying formula type, caloric density, and daily volume. Nursing staff or home health clinicians confirm tube placement per facility protocol, initiate formula administration via bolus or continuous pump, document intake and tolerance, and coordinate supplies and billing. The supplier dispenses the approved enteral formula in measured units based on 100 calories = 1 unit and submits claims using B4150 for the formula supply. Clinical monitoring includes daily assessment of gastrointestinal tolerance, weight trends, fluid balance, and periodic clinician review for changes in caloric needs or route of administration.
