Pnctr w/o fb of abd wall, left low q w penet perit cav, subs

This code signifies a puncture injury to the lower left abdominal wall that has breached the peritoneal lining, occurring during a follow-up visit for the initial injury. It specifically excludes cases where a foreign object remains embedded in the wound.

Apply this code for subsequent encounters when a patient is being treated for a previously diagnosed puncture wound of the left lower abdominal quadrant that penetrated the peritoneal cavity. This would include follow-up appointments for wound care, monitoring for complications, or assessment of healing after the initial treatment.

• Ensure documentation clearly states "subsequent encounter" and specifies the left lower quadrant.
• Verify that there is no foreign body present in the wound, as this would necessitate a different code.
• Confirm peritoneal penetration; superficial puncture wounds without penetration are coded differently.
