Pnctr of abd wall w/o fb, l flank with penet perit cav, init

This code signifies a sharp, penetrating injury to the left flank area of the abdomen, where the wound tract extends through the abdominal wall and breaches the peritoneal lining. It specifically excludes cases where a foreign object remains embedded in the tissue.

Apply this code for patients presenting with an acute, non-missile-related puncture wound to the left flank that has demonstrably entered the abdominal cavity. This is typically used for initial treatment encounters following such an injury, such as from a stab wound or impalement.

• Ensure documentation clearly specifies "left flank" and "penetration into peritoneal cavity."
• Verify the absence of a retained foreign body; if present, a different code is required.
• The "A" suffix indicates an initial encounter for active treatment of the injury.
