Clinical & Coding Specifications

Clinical Context

A typical patient is an adult with a surgically created urinary stoma (urostomy) following cystectomy for invasive bladder cancer, neurogenic bladder with failed reconstruction, or severe trauma to the lower urinary tract. The patient presents to an outpatient durable medical equipment (DME) clinic, wound-ostomy-continence (WOC) nurse visit, or home health visit for ongoing stoma care and supply needs. The clinician assesses stoma integrity, peristomal skin condition, and current pouching system fit. When the existing pouching system requires replacement due to wear, leakage, or change in stoma size, a new ostomy urine pouch with an integrated faceplate is dispensed and documented using billing code A4379. Typical workflow includes verification of medical necessity, review of prior supplies, measurement of stoma, selection of appropriate flange/faceplate size, patient education on application and emptying, and documentation of diagnosis supporting urostomy care and supply need. Sites of service commonly include outpatient clinics, home health visits, long-term care facilities, and DME supplier locations.
