Code Description

ICD-10 S31.631 is a billable code used to indicate a diagnosis of puncture wound without foreign body of abdominal wall, left upper quadrant with penetration into peritoneal cavity.

Key Diagnostic Point:

A puncture wound of the abdominal wall in the left upper quadrant that penetrates the peritoneal cavity is a serious injury that can lead to significant complications. This type of wound typically occurs due to trauma, such as a stab wound or a gunshot wound, but can also result from accidental injuries. The peritoneal cavity houses vital organs, including the stomach, spleen, and parts of the pancreas and colon. Penetration into this cavity can result in peritonitis, hemorrhage, and damage to internal organs. Immediate medical evaluation is crucial, often requiring imaging studies to assess the extent of the injury. Surgical intervention may be necessary to repair any damaged organs and to prevent infection. The management of such injuries involves a multidisciplinary approach, including trauma surgeons, radiologists, and critical care specialists, to ensure optimal patient outcomes.

Code Complexity Analysis

Complexity Rating: High

High Complexity

Complexity Factors

  • Requires precise documentation of the injury mechanism and location.
  • Differentiation from similar codes for abdominal injuries.
  • Potential for multiple organ involvement complicating coding.
  • Need for accurate assessment of peritoneal cavity involvement.

Audit Risk Factors

  • Inadequate documentation of the mechanism of injury.
  • Failure to document surgical interventions performed.
  • Misclassification of the injury type (e.g., puncture vs. laceration).
  • Inconsistent coding of associated injuries or complications.
