HCPCS Level II code B4152 identifies a nutritionally complete, calorically dense enteral formula (≥ 1.5 kcal/ml) with intact nutrients intended for delivery via an enteral feeding tube. This code matters nationally because enteral nutrition is a common medically necessary intervention across hospitals, long-term care, and home health settings, and high-calorie formulas are routinely used for patients with elevated energy requirements or volume-restricted feeding regimens. Payers influence coverage, utilization management, and documentation requirements tied to tube-fed nutrition.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context for use of high-calorie enteral formulas, payer coverage considerations, and typical service settings. The publication outlines benchmarks and common utilization drivers, highlights relevant billing and documentation practices tied to B4152, and summarizes potential policy updates affecting enteral nutrition coverage. Data not available in the input will be noted where applicable. This overview is intended for clinicians, billing professionals, and policy analysts seeking a national perspective on enteral formula coding and coverage.
