Umbilical hernia with obstruction, without gangrene

This code signifies an umbilical hernia where the bowel or other abdominal contents are trapped, leading to a blockage of the intestinal lumen. This obstruction is present without evidence of tissue death or necrosis in the entrapped contents. It represents a serious complication of an umbilical hernia requiring prompt medical attention.

Assign this code when documentation clearly indicates an umbilical hernia with signs and symptoms of obstruction, such as abdominal pain, vomiting, distention, and inability to pass gas or stool. The physician's notes must explicitly state "obstruction" and confirm the absence of gangrene. This code is appropriate for both initial and subsequent encounters for this condition.

• Ensure documentation explicitly differentiates between incarcerated, strangulated, and obstructed hernias.
• Do not use this code if gangrene is present; a different subcategory is required.
• Always review operative reports or physician notes for specific details regarding the hernia's status and any complications.
