Stenosis of incontinent stoma of urinary tract

This code describes a narrowing or stricture of a surgically created opening (stoma) in the urinary tract that is designed to be incontinent, meaning it continuously drains urine. This stenosis can impede urine flow, potentially leading to complications such as hydronephrosis or infection.

Use this code when documentation specifies a stricture or narrowing of an incontinent urinary stoma, such as a urostomy or ileal conduit. This diagnosis is supported by physician notes detailing the stoma's compromised patency and associated symptoms or findings.

• Always specify the underlying condition or reason for the original incontinent stoma if known and still relevant.
• Distinguish this from stenosis of a continent stoma (N99.523) or other complications of urinary stoma (N99.520-N99.529).
• Ensure documentation clearly states the stoma is "incontinent" to support this specific code.
