Injury of peritoneum, initial encounter

This code signifies damage to the peritoneum, the membrane lining the abdominal cavity and covering most abdominal organs. This injury can range from contusions to lacerations or perforations, often resulting from blunt or penetrating trauma to the abdomen.

Apply this code for the initial treatment of a patient presenting with a newly diagnosed injury to the peritoneum. This typically occurs following motor vehicle accidents, falls, assaults, or other traumatic incidents affecting the abdominal region.

• Always assign an external cause code to describe the circumstances of the injury.
• Look for documentation specifying the "initial encounter" for treatment of this specific injury.
• Code any associated organ injuries (e.g., liver, spleen, bowel) separately.
