Lac w fb of abd wall, unsp quadrant w penet perit cav, init

This code describes a traumatic injury to the abdominal wall characterized by a cut or tear that includes a foreign object embedded within the wound. Crucially, the injury extends through the abdominal wall and into the peritoneal cavity, indicating a significant breach. The specific quadrant of the abdomen is not documented.

Use this code for initial encounters involving penetrating abdominal trauma where a foreign body (e.g., knife, glass, projectile) has entered the abdominal wall and is confirmed to have breached the peritoneum. This is applicable when the exact location within the abdomen (e.g., upper right, lower left) is not specified in the medical record.

• Ensure documentation explicitly states "initial encounter" and confirms peritoneal penetration.
• Look for details regarding the foreign body and mechanism of injury.
• If the specific abdominal quadrant is documented, a more precise code from the S31.62- series should be used.
