Code Description

ICD-10 S21.311 is a billable code used to indicate a diagnosis of laceration without foreign body of right front wall of thorax with penetration into thoracic cavity.

Key Diagnostic Point:

S21.311 refers to a laceration of the right front wall of the thorax that penetrates into the thoracic cavity but does not involve a foreign body. This type of injury is often the result of blunt or penetrating trauma, such as from a knife or a gunshot wound. The thoracic cavity houses vital organs, including the lungs and heart, making such injuries potentially life-threatening. Complications may include pneumothorax (air in the pleural space), hemothorax (blood in the pleural space), rib fractures, and cardiac injuries. Immediate medical intervention is crucial to assess the extent of the injury, manage any associated complications, and determine the need for surgical intervention. Surgical procedures may involve thoracotomy or video-assisted thoracoscopic surgery (VATS) to repair the laceration and address any damage to the underlying structures. Proper documentation of the mechanism of injury, clinical findings, and treatment provided is essential for accurate coding and billing.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Need for detailed documentation of the mechanism of injury
  • Assessment of associated injuries (e.g., rib fractures, pneumothorax)
  • Potential for surgical intervention and its documentation
  • Differentiation from similar codes for thoracic injuries

Audit Risk Factors

  • Inadequate documentation of the injury mechanism
  • Failure to document associated injuries or complications
  • Incorrect coding of the injury site or type
  • Lack of clarity in surgical intervention documentation

Documentation Requirements

Detailed operative reports, imaging studies, and notes on the mechanism of injury.

Common Clinical Scenarios

Management of penetrating trauma, rib fractures, and thoracic cavity injuries.

Billing Considerations

Accurate documentation of surgical procedures and post-operative care is critical for coding.

Inclusion Criteria

Use S21.311 When
  • According to ICD
  • 10 guidelines, S21
  • 311 should be used when a laceration of the thoracic wall is documented without a foreign body and with penetration into the thoracic cavity
  • Coders must ensure that the documentation supports the diagnosis and that any associated injuries are also coded appropriately

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of thoracic injuries, improving the accuracy of data collection and reimbursement processes. S21.311 provides a clear distinction for lacerations without foreign bodies, which was less defined in ICD-9.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of thoracic injuries, improving the accuracy of data collection and reimbursement processes. S21.311 provides a clear distinction for lacerations without foreign bodies, which was less defined in ICD-9.

Reimbursement & Billing Impact

reimbursement processes. S21.311 provides a clear distinction for lacerations without foreign bodies, which was less defined in ICD-9.
