Code Description

ICD-10 S31.639 is a billable code used to indicate a diagnosis of puncture wound without foreign body of abdominal wall, unspecified quadrant with penetration into peritoneal cavity.

Key Diagnostic Point:

A puncture wound of the abdominal wall occurs when a sharp object penetrates the skin and underlying tissues, resulting in an opening that may extend into the peritoneal cavity. This type of injury can arise from various incidents, including accidents, assaults, or surgical complications. The absence of a foreign body indicates that the wound is not caused by an object that remains lodged within the body. The peritoneal cavity is a potential space within the abdomen that houses various organs, and penetration into this area can lead to serious complications such as peritonitis, hemorrhage, or organ damage. Clinical evaluation typically involves a thorough physical examination, imaging studies, and possibly exploratory surgery to assess the extent of the injury and determine the appropriate intervention. Emergency surgical intervention may be necessary to repair any damage to internal organs, control bleeding, and prevent infection. The management of such wounds requires a multidisciplinary approach, often involving trauma surgeons, emergency medicine physicians, and critical care specialists.
