Summary & Overview
HCPCS A4755: Blood Tubing, Arterial and Venous Combined, for Hemodialysis
HCPCS Level II code A4755 represents a combined arterial and venous blood tubing set used in hemodialysis. As a consumable supply integral to each dialysis treatment, this code is relevant nationwide for facility billing, supply chain management, and cost-monitoring across dialysis providers. The code matters because tubing sets are required for every hemodialysis session and factor into per-treatment supply costs and reimbursement considerations.
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 this code denotes, its clinical role in hemodialysis care, and how it is typically used in outpatient dialysis centers. The publication provides benchmarks and comparative context where available, notes common billing practices, and summarizes policy or coding guidance that affects billing and coverage for hemodialysis supplies. It also outlines implications for procurement and cost accounting within dialysis programs.

Clinical & Coding Specifications
Clinical Context
A 62-year-old patient with end-stage renal disease presents to an outpatient dialysis center for scheduled hemodialysis. Vascular access is an established arteriovenous fistula with needle cannulation. The typical workflow includes patient arrival, pre-dialysis assessment by a registered nurse, priming and connection of the hemodialysis machine, and attaching disposable supplies including the combined arterial and venous blood tubing set billed under A4755. The tubing set is used to circulate the patient’s blood through the dialysis circuit to the dialyzer and back to the patient. The service typically occurs in an ambulatory dialysis facility, hospital outpatient dialysis unit, or skilled nursing facility-based dialysis program. Clinical staff monitor hemodynamics, access site bleeding, and machine parameters throughout the treatment. The tubing is single-use and replaced for each dialysis session or sooner if contamination or malfunction occurs.
