What This Code Means

Protrusion or bulging of a surgically created urine drainage opening that controls urine flow through the abdominal wall.

Coding Tips

•Herniation indicates tissue protrusion; document size and symptoms if present
•Differentiate from parastomal hernia which may have a separate code

Clinical Significance

Herniation at a continent urinary stoma site compromises the structural integrity of the carefully constructed continence mechanism. This complication may require complex surgical repair to restore both structural integrity and functional continence.

Documentation Requirements

✓Documentation of continent urinary stoma type
✓Description of hernia characteristics and size
✓Impact on continence mechanism function
✓Clinical examination findings
✓Associated symptoms (pain, bulging, functional loss)
✓Complications (incarceration, obstruction)
✓Surgical intervention planned or performed
