Billing Code Overview

HCPCS Level II code A6590 describes external urinary catheters; disposable, with wicking material, for use with suction pump, per month. The service type is durable medical equipment/supply (external urinary catheter supply) intended for patients requiring urinary collection managed with suction-assisted systems. The typical site of service is home care or other outpatient/community settings where a suction pump is used to manage urinary drainage.

Clinical & Coding Specifications

Clinical Context

A typical patient is an adult or geriatric individual with urinary incontinence or impaired bladder emptying who requires an external urinary catheter system with wicking material for use with a suction pump on a monthly basis. The device described by A6590 is a disposable external urinary catheter designed for patients who need continuous low-pressure suction drainage to manage moisture, protect skin integrity, and reduce odor in settings where indwelling catheterization is contraindicated or undesirable.

A realistic clinical workflow: the clinician (home health nurse, wound/ostomy nurse, or urology clinic staff) evaluates the patient during a home visit or outpatient visit, documents the indication (e.g., urinary incontinence with perineal skin breakdown, high-output moisture complicating wound care), and prescribes the external catheter with suction compatibility. The prescription is submitted to the durable medical equipment provider for monthly supply under A6590. The supplier coordinates delivery to the patient’s home or facility. Nursing staff trains the patient or caregiver on proper placement, suction pump connection, containment and disposal, and monitors for skin irritation, leakage, or device malfunction during follow-up visits. Typical sites of service include the patient’s home, skilled nursing facility, long-term care facility, or outpatient wound/ostomy/urology clinic. Documentation includes the medical necessity, quantity per month, device description A6590, and clinical findings supporting avoidance of indwelling catheter use.
