Summary & Overview
HCPCS Level II A4381: Urinary Ostomy Pouch for Faceplate, Plastic, Each
HCPCS Level II code A4381 identifies a single plastic urinary ostomy pouch intended for attachment to a faceplate. This supply-category code is used nationally to bill for a common component of urinary diversion systems, supporting patients with urostomies in ambulatory and home-care settings. The code matters because ostomy supplies are recurring, clinically essential items that affect patient quality of life and ongoing durable medical equipment (DME) spending.
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 for urinary ostomy pouches, billing considerations tied to unit-based supply coding, and the typical sites of service where A4381 is supplied. The publication outlines benchmark concepts for utilization and reimbursement patterns, common billing modifiers, and practical coding relationships to help clinicians, billers, and policy analysts understand how A4381 fits into broader ostomy supply coverage.
Data not available in the input for associated taxonomies, specific ICD-10 diagnoses, and related codes is noted where applicable.

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with a permanent or temporary urinary diversion who requires an ostomy pouch designed to attach to an existing faceplate (flange) on a urostomy appliance. Typical scenarios include a patient post-radical cystectomy with ileal conduit, or a patient with a continent cutaneous diversion who uses an external urinary pouch on a faceplate for appliance management. The clinical workflow: a wound/ostomy nurse or outpatient medical supply vendor assesses stoma size and peristomal skin, confirms faceplate type and compatibility, selects an appropriate plastic urinary pouch (A4381) to mate with the patient’s faceplate, documents pouch type, quantity dispensed, and patient education provided, and supplies the pouch to the patient for ongoing home use. Usual sites of service include outpatient ostomy clinics, home care supply delivery, durable medical equipment suppliers, and hospital discharge supply coordination. Patient factors that guide pouch selection include stoma size and shape, skin condition, level of manual dexterity, and frequency of appliance changes.
