Code Description

ICD-10 S31.643 is a billable code used to indicate a diagnosis of puncture wound with foreign body of abdominal wall, right lower quadrant with penetration into peritoneal cavity.

Key Diagnostic Point:

A puncture wound with a foreign body in the right lower quadrant of the abdominal wall indicates a significant injury that may involve the peritoneal cavity. This type of injury often results from penetrating trauma, such as stab wounds or gunshot wounds, and can lead to serious complications, including peritonitis, hemorrhage, and organ damage. The presence of a foreign body complicates the clinical picture, as it may necessitate surgical intervention to remove the object and repair any damage to the abdominal organs. Patients may present with abdominal pain, tenderness, and signs of internal bleeding. Immediate assessment through imaging studies, such as ultrasound or CT scans, is crucial to evaluate the extent of the injury and guide treatment. Emergency surgical intervention is often required to address any perforation of the bowel or other intra-abdominal structures, and to prevent further complications.
