Herniation of incontinent stoma of urinary tract

This code describes a protrusion or bulging of an incontinent urinary stoma, such as a urostomy, due to a defect in the abdominal wall. This herniation can involve the bowel, omentum, or other abdominal contents pushing through the fascial opening around the stoma. It is a complication that can lead to discomfort, difficulty with appliance adherence, and potential obstruction.

Use this code when documentation clearly indicates a hernia associated with an incontinent urinary stoma. This typically occurs in patients who have undergone urinary diversion procedures, such as an ileal conduit, and subsequently develop a parastomal hernia. Documentation should specify the stoma as "incontinent" and describe the presence of a hernia.

• Distinguish from N99.522 (herniation of continent stoma) and N99.520 (herniation of intestinal stoma) based on the type of stoma.
• Code any associated complications of the hernia, such as obstruction or gangrene, as secondary diagnoses.
• Ensure the documentation specifies "incontinent" to accurately select this code over other stoma herniation codes.
