Summary & Overview
HCPCS Level II A4346: Foley Three-Way Indwelling Catheter for Continuous Irrigation
HCPCS Level II code A4346 identifies a three-way Foley indwelling catheter intended for continuous bladder irrigation. This supply is commonly used in urologic surgery and in clinical situations requiring ongoing irrigation to prevent clot retention or to manage hematuria. Nationally, accurate coding of device supplies like A4346 affects hospital billing, supply chain reporting, and outpatient durable medical equipment claims processing.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context and typical sites of service, billing and coding considerations for device supplies, common modifiers encountered in claims submissions, and where to find additional coding guidance. The publication also outlines benchmarking topics and policy updates relevant to device supply reimbursement and hospital supply management. Data not available in the input will be identified as such in the detailed sections.

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult inpatient or emergency department patient with gross hematuria, clot retention, or postoperative bladder irrigation needs following transurethral resection of the prostate (TURP) or bladder tumor resection. The clinical workflow begins with assessment of urinary retention, bladder irrigation requirements, and hemodynamic stability. Indications for insertion of an indwelling three-way Foley catheter (A4346) include ongoing gross bleeding requiring continuous bladder irrigation (CBI), evacuation of bladder clots, or provision of continuous irrigation after urologic procedures.
The procedure is performed by a urologist, advanced practice provider, or trained inpatient nursing staff depending on facility policy. After informed consent and appropriate analgesia or local anesthesia, aseptic catheter insertion is performed. The three-way catheter allows instillation of irrigation fluid through the inflow lumen and drainage through the outflow lumen while a third lumen permits balloon inflation and pressure monitoring. Post-insertion management includes setting continuous irrigation rates, monitoring urine color and output, maintaining catheter patency, and documenting the device code A4346, insertion date/time, manufacturer/size, and clinical indication in the medical record. Typical sites of service are inpatient hospital units (including ICU), the emergency department, and the operating room when placed intraoperatively.
