Summary & Overview
HCPCS B4180: Parenteral Dextrose Solution >50% (Home Mix)
HCPCS Level II code B4180 denotes a home-mix parenteral nutrition solution of dextrose (carbohydrate) concentration greater than 50%, with billing units defined as 500 ml per unit. This code is relevant for home infusion therapy programs, durable medical equipment and infusion suppliers, home health agencies, and payers overseeing nutrition support for patients who require central or peripheral parenteral access outside of the acute-care setting. Nationally, parenteral nutrition codes like B4180 influence coverage determinations, supply reimbursement, and clinical management of complex nutritional needs.
Key payers included in this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of coding intent and clinical context, payer coverage scope, common modifiers and billing considerations, and how B4180 fits within home infusion service lines. The publication covers benchmark considerations for supply reimbursement, typical sites of service and clinical indications, and the operational implications for home infusion providers and payers. Data not available in the input is noted where applicable; the content focuses on nationally relevant policy and billing interpretation rather than state-specific rules.
Billing Code Overview
HCPCS Level II code B4180 describes a parenteral nutrition solution consisting of carbohydrates (dextrose) greater than 50%, provided as a home mix. The code's unit definition is 500 ml = 1 unit.
Service type: Parenteral nutrition administration (nutrition supply)
Typical site of service: Home infusion / home health setting
Clinical & Coding Specifications
Clinical Context
A typical patient for B4180 is an adult receiving home parenteral nutrition who requires a concentrated dextrose solution (>50%) as part of a compounded regimen. For example, a patient with prolonged small bowel obstruction and short bowel syndrome has insufficient enteral absorption and is discharged from an inpatient stay to a home infusion program. The home infusion pharmacist compounds a 500 mL unit of parenteral carbohydrate solution (dextrose >50%) to be administered through the patient’s central venous catheter via an infusion pump. The clinical workflow includes physician order for total parenteral nutrition (TPN) specifying caloric goals, pharmacy compounding of the dextrose-containing component under sterile conditions, home infusion nursing education for catheter and pump management, and regular outpatient laboratory monitoring (electrolytes, glucose, liver function tests) with periodic physician follow-up to adjust the TPN formulation.
