Unsp opn wnd abd wall, left lower q w penet perit cav, sqla

This code signifies a past open wound, such as a laceration or puncture, affecting the left lower abdominal wall that extended into the peritoneal cavity. The "sequela" designation indicates that this code is used to report a condition or complication arising as a direct result of this previous injury, rather than the acute injury itself.

Use this code when documenting a long-term effect or complication directly attributable to a previously sustained open wound of the left lower abdominal wall that penetrated the peritoneal cavity. Examples include chronic pain, adhesions, or scar tissue formation in the left lower quadrant resulting from the original injury. This code is not for the initial treatment of the acute wound.

• Always ensure documentation clearly links the current condition to the specified past injury.
• Verify the wound location (left lower quadrant) and depth (penetration into peritoneal cavity) are explicitly stated in the patient's history.
• This "S" seventh character indicates a sequela; do not use for initial encounter (A) or subsequent encounter (D).
