Code Description

ICD-10 S31.629 is a billable code used to indicate a diagnosis of laceration with foreign body of abdominal wall, unspecified quadrant with penetration into peritoneal cavity.

Key Diagnostic Point:

S31.629 refers to a laceration of the abdominal wall that is accompanied by a foreign body and has penetrated into the peritoneal cavity. This condition typically arises from traumatic injuries, such as stab wounds, gunshot wounds, or accidents involving sharp objects. The presence of a foreign body complicates the injury, as it can lead to infection, internal bleeding, or damage to surrounding organs. The peritoneal cavity houses vital organs, and penetration can result in serious complications, including peritonitis or organ perforation. Emergency surgical intervention is often required to remove the foreign body, repair the laceration, and address any damage to internal structures. Accurate coding of this condition is crucial for appropriate treatment planning and reimbursement, as it reflects the severity and complexity of the injury.
