Lac w/o fb of abd wall, left lower q w penet perit cav, init

This code signifies an open wound on the lower left side of the abdomen that has breached the peritoneal lining, but without any foreign material embedded in the wound. It indicates a full-thickness injury to the abdominal wall in this specific quadrant, extending into the abdominal cavity.

Apply this code for patients presenting with a fresh, non-penetrating laceration to the left lower quadrant of the abdomen that is confirmed to have entered the peritoneal space. This is appropriate for initial treatment of such an injury, often seen after trauma where the skin, muscle, and peritoneum are all compromised.

• Confirm documentation explicitly states "left lower quadrant" and "penetration into peritoneal cavity."
• Ensure there is no mention of a foreign body in the wound.
• The "A" at the end signifies an initial encounter for this injury.
