HCPCS A4311: Insertion Tray for Indwelling Foley Catheter, No Drainage Bag

HCPCS Level II code A4311 designates an insertion tray without a drainage bag for placement of an indwelling Foley-type catheter (two-way, latex with coating). The code identifies the supply kit used during catheter insertion procedures and is relevant to billing for catheter placement episodes across inpatient, outpatient, and long-term care settings. Nationally, clear coding for catheter supplies supports accurate reimbursement, inventory tracking, and quality measurement related to urinary catheter use.

Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find guidance on the clinical context for use of A4311, typical sites of service, and what the code represents on a service line. The publication covers common billing considerations, documentation points that affect supply coding, and how A4311 may appear on claim lines alongside catheter placement services. It also outlines available benchmarks and policy updates where applicable. Data not available in the input will be identified as such in relevant sections.

This overview is intended for billing professionals, practice managers, and policy analysts seeking a concise reference to HCPCS Level II code A4311 and its role in procedural supply coding for Foley catheter insertion.

Clinical & Coding Specifications

Clinical Context

A typical patient is an adult with urinary retention, neurogenic bladder, or perioperative need for short-term bladder drainage who requires placement of an indwelling Foley catheter using a sterile insertion tray. The procedure is performed in an outpatient clinic, emergency department, hospital bedside, or perioperative setting by a trained clinician (urology nurse, registered nurse, advanced practice provider, or physician). The workflow includes verification of indication and allergies, informed consent when required, hand hygiene and sterile technique, application of sterile drape and lubricant, aseptic insertion of a two-way latex Foley catheter with appropriate coating (e.g., silicone or hydrophilic), inflation of the retention balloon, connection of the catheter to a drainage system when indicated, documentation of catheter size and volume used for balloon inflation, patient education on catheter care, and scheduling of follow-up or catheter removal as clinically appropriate.
