Pnctr w/o fb of abd wall, l upr q w penet perit cav, subs

This code describes a puncture injury to the left upper quadrant of the abdominal wall that has breached the peritoneal cavity, but without any foreign object remaining in the wound. This indicates a deep penetration that has entered the abdominal cavity itself.

Use this code for follow-up encounters for a patient who previously sustained such an injury. This would include subsequent visits for wound care, monitoring for complications, or evaluation of healing after the initial treatment.

• Ensure documentation specifies "subsequent encounter" for this injury.
• Verify the wound location is precisely the left upper quadrant and that penetration into the peritoneal cavity is confirmed.
• Confirm the absence of a foreign body; if present, a different code would be required.
