Code Description

ICD-10 S31.655 is a billable code used to indicate a diagnosis of open bite of abdominal wall, periumbilic region with penetration into peritoneal cavity.

Key Diagnostic Point:

An open bite of the abdominal wall in the periumbilical region with penetration into the peritoneal cavity is a serious injury that typically results from a penetrating trauma, such as an animal bite or a sharp object. This type of injury can lead to significant complications, including peritonitis, hemorrhage, and damage to internal organs. The periumbilical area is particularly vulnerable due to its anatomical location, which houses various vital structures. The clinical presentation may include abdominal pain, swelling, and signs of infection. Immediate medical evaluation is crucial, as surgical intervention is often required to repair the abdominal wall and address any internal injuries. The management of such injuries involves a multidisciplinary approach, including trauma surgery, infectious disease specialists, and critical care teams, to ensure comprehensive care and optimal outcomes.

Complexity Rating: High

High Complexity

Complexity Factors

  • Requires detailed documentation of the mechanism of injury.
  • Involves understanding of anatomical structures affected.
  • Potential for multiple associated injuries complicating coding.
  • Need for precise coding to reflect the severity and specifics of the injury.

Audit Risk Factors

  • Inadequate documentation of the mechanism of injury.
  • Failure to document associated injuries or complications.
  • Incorrect coding of the severity of the injury.
  • Lack of surgical documentation to support the diagnosis.
