Lac w/o fb of abd wall, unsp q w penet perit cav, sequela

This code describes a healed injury to the abdominal wall, specifically a laceration that extended into the peritoneal cavity, where the exact location on the abdomen was not specified, and no foreign body was involved. It signifies a long-term effect or complication arising from the initial injury, rather than the acute event itself.

Use this code when documenting a patient presenting with a sequela (e.g., chronic pain, adhesion formation, hernia) resulting from a past abdominal wall laceration that penetrated the peritoneal cavity. This code is appropriate when the original injury's specific abdominal quadrant was not documented or is unknown, and the patient is no longer in the acute phase of treatment for the laceration.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure documentation clearly states the injury is a "sequela" or "late effect" of a previous laceration.
• Verify that the original laceration involved penetration into the peritoneal cavity and did not involve a foreign body.
