Stenosis of continent stoma of urinary tract

This code describes a narrowing or obstruction of a surgically created, continent urinary stoma. This stoma is designed to retain urine until catheterization, and its stenosis can impede drainage and lead to urinary retention or infection. It specifically refers to a complication of a urinary diversion procedure where a reservoir is created.

Apply this code when documentation indicates a patient has a continent urinary stoma that has developed a stricture or narrowing. This typically presents with difficulty catheterizing the stoma, decreased urine output, or recurrent urinary tract infections related to impaired drainage. Supporting documentation would include physician notes detailing the stoma's patency issues, diagnostic imaging, or procedural reports for stoma revision.

• Ensure the documentation specifies "continent" stoma to differentiate from other types of urinary stomas.
• Code any associated urinary retention (e.g., R33.8) or urinary tract infection (e.g., N39.0) as secondary diagnoses.
• Do not confuse with stenosis of a non-continent urinary stoma, which would be coded differently.
