Code Description

ICD-10 S31.635 is a billable code used to indicate a diagnosis of puncture wound without foreign body of abdominal wall, periumbilic region with penetration into peritoneal cavity.

Key Diagnostic Point:

S31.635 describes a puncture wound located in the periumbilical region of the abdominal wall that has penetrated into the peritoneal cavity without the presence of a foreign body. This type of injury is often the result of blunt or penetrating trauma, such as a stab wound or an accidental puncture from a sharp object. The peritoneal cavity houses vital organs, and penetration can lead to serious complications, including peritonitis, hemorrhage, and organ damage. Clinical evaluation typically involves a thorough physical examination, imaging studies such as ultrasound or CT scans, and possibly exploratory surgery to assess the extent of the injury. Management may require emergency surgical intervention to repair any damage and prevent infection. The absence of a foreign body is significant, as it influences the treatment approach and potential complications. Accurate coding is essential for proper billing and to reflect the severity of the injury in the patient's medical record.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Need for precise documentation of the injury's location and depth
  • Differentiation from similar codes for puncture wounds with foreign bodies
  • Potential for associated complications requiring additional codes
  • Variability in clinical presentation and management based on the mechanism of injury

Audit Risk Factors

  • Inadequate documentation of the mechanism of injury
  • Failure to specify the extent of peritoneal involvement
  • Incorrect coding of associated injuries or complications
  • Lack of clarity in operative reports if surgery is performed

Specialty Focus

Emergency Medicine

Documentation Requirements

Detailed documentation of the mechanism of injury, physical examination findings, and any imaging results.

Common Clinical Scenarios

Patients presenting with stab wounds, accidental punctures, or trauma from falls.

Billing Considerations

Ensure that all relevant details about the injury and treatment are captured to support the coding.

General Surgery

Documentation Requirements

Operative reports must clearly describe the findings during surgery, including any repairs made to the peritoneal cavity.

Common Clinical Scenarios

Exploratory laparotomy for suspected abdominal injuries following trauma.

Billing Considerations

Accurate coding of any additional procedures performed during surgery is crucial.
