Summary & Overview

HCPCS B4197: Parenteral Nutrition Premix, 74–100 g Protein

HCPCS Level II code B4197 identifies a compounded parenteral nutrition premix containing amino acids and carbohydrates with electrolytes, trace elements, and vitamins, formulated to deliver 74 to 100 grams of protein. This code applies to premixed parenteral nutrition solutions prepared for intravenous administration and is relevant across inpatient, outpatient infusion, long-term care, and home infusion settings. Nationally, accurate coding of parenteral nutrition is important for care coordination, supply chain management, and appropriate payment for complex compounded products.

Key payers referenced in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of the clinical context for compounded parenteral nutrition, the typical sites of service where B4197 is billed, and what coding this item represents. The publication also summarizes commonly used modifiers and payer coverage considerations where available, and highlights benchmarks and policy updates relevant to billing and reimbursement for compounded parenteral nutrition products.

Clinical & Coding Specifications

Clinical Context

A 62-year-old hospitalized patient with postoperative ileus after major abdominal surgery is unable to tolerate enteral nutrition. The patient has been assessed by a multidisciplinary team (surgeon, hospitalist, registered dietitian, and pharmacy) and meets criteria for parenteral nutrition due to prolonged gastrointestinal dysfunction and inadequate oral/enteral intake. The clinician orders a compounded parenteral nutrition solution described by billing code B4197 — a premixed parenteral nutrition containing 74 to 100 grams of protein with amino acids, dextrose/carbohydrate, electrolytes, trace elements, and vitamins.

Care workflow:

Initial assessment and documentation of inability to use the GI tract for nutrition and calculation of protein and caloric needs.
Order placement for B4197 by the prescribing physician or advanced practice provider with indications, rate, and duration.
Pharmacy compounding staff prepare the premix under sterile conditions, verify components, and label the admixture.
Nursing initiates central venous or peripheral parenteral administration per facility policy, monitors vital signs, fluid balance, electrolytes, and blood glucose, and documents tolerance.
Daily multidisciplinary review for adjustments, labs, and plans for transition to enteral or oral feeding when clinically appropriate.
