Summary & Overview
HCPCS Level II B4216: Parenteral Nutrition Additives, Home Mix, Per Day
HCPCS Level II code B4216 denotes daily provision of parenteral nutrition additives in a home-mix preparation, covering vitamins, trace elements, heparin, and electrolytes for patients receiving parenteral nutrition at home. This code is important nationally for accurate billing of home infusion services and for tracking utilization of supplemental components distinct from base parenteral nutrition solutions. Proper use of B4216 affects reimbursement for home infusion providers and helps payers monitor additive usage and clinical appropriateness.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of what the code represents, typical sites of service, and the clinical context for use. The publication also outlines common benchmark and policy considerations relevant to home infusion billing, such as distinctions between base parenteral nutrition and additive supplies, documentation elements typically reviewed by payers, and how B4216 interacts with related home infusion service lines.
This summary provides clinicians, coding professionals, and payers a national-level reference on the code’s purpose, application, and areas to consider when reviewing claims and coverage.

Clinical & Coding Specifications
Clinical Context
A typical patient receiving services billed under B4216 is an adult or pediatric patient discharged from an acute care hospital for home care who requires ongoing parenteral nutrition (PN) supplementation with daily additives. The patient often has intestinal failure, short bowel syndrome, severe malabsorption, or prolonged bowel rest following high-risk abdominal surgery or pancreatitis. A home infusion nurse coordinates with a physician (often a gastroenterologist or nutrition support physician) and a home infusion pharmacy. The workflow includes: ordering and medical necessity documentation by the prescribing clinician; individualized PN formulation and daily addition specification (vitamins, trace elements, heparin, electrolytes) by the compounding pharmacy; delivery of the home-mixed, additive-containing PN bag to the patient’s residence; nursing instruction for administration and catheter care; and routine monitoring of weight, metabolic panel, liver function tests, and catheter-related complications during home health or outpatient follow-up visits.
