Summary & Overview
HCPCS Level II A4404: Ostomy Ring, Each
HCPCS Level II code A4404 represents an ostomy ring sold as an individual component. Ostomy rings are part of ostomy pouching systems and are used to create a secure seal around a stoma, helping protect peristomal skin and maintain appliance adhesion. Nationwide, accurate coding for ostomy supplies affects coverage determinations, durable medical equipment (DME) billing, and supply management for patients with stomas.
Key payers addressed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find national-level context on the code’s clinical role, typical settings of use, and the payer landscape relevant to coverage and claims processing. The publication summarizes common billing themes, documentation considerations, and the operational implications for supply procurement and claims submission. Where available, benchmarks and policy updates relating to ostomy supply coding and DME coverage are summarized to inform coders, billing staff, and supply chain managers.
This overview is intended for a national audience and focuses on coding, clinical context, and payer considerations rather than state-specific rules or prescriptive clinical guidance. Data not available in the input is identified where relevant.

Clinical & Coding Specifications
Clinical Context
An adult patient with a permanent or temporary stoma (colostomy, ileostomy, or urostomy) presents to a wound/ostomy clinic or outpatient surgery center for routine pouching system maintenance or replacement of peristomal support devices. The clinician assesses peristomal skin integrity, measures the stoma site, and determines that an ostomy ring is needed to create a seal between the stoma and the skin barrier to prevent leakage and protect peristomal skin. The ostomy ring (A4404) is provided as a single-item supply during the visit and is commonly applied by an ostomy nurse, enterostomal therapist, or a wound care nurse. Typical workflow: patient check-in, brief clinical assessment, selection and preparation of the ostomy ring, application to the skin barrier or directly to peristomal skin as indicated, patient education on wear time and replacement, and documentation of item description, quantity, and reason for use in the medical record. Typical sites of service include outpatient wound/ostomy clinics, home health visits, long-term care facilities, and outpatient ambulatory surgery centers. Clinical scenarios include management of leakage with peristomal skin irritation, creation of an improved seal for irregular stoma contours, or routine replacement during a scheduled ostomy supply visit.
