Code Description

ICD-10 S21.142 is a billable code used to indicate a diagnosis of puncture wound with foreign body of left front wall of thorax without penetration into thoracic cavity.

Key Diagnostic Point:

A puncture wound with a foreign body in the left front wall of the thorax indicates an injury where an object has penetrated the skin and underlying tissues but has not breached the thoracic cavity. This type of injury can occur due to various mechanisms, such as a stab wound, a gunshot wound, or an accident involving sharp objects. Clinically, it is essential to assess for associated injuries, including rib fractures, pneumothorax, hemothorax, or cardiac injuries, which may complicate the clinical picture. The absence of penetration into the thoracic cavity is crucial, as it significantly reduces the risk of life-threatening complications such as respiratory distress or cardiac tamponade. Management typically involves wound care, possible surgical intervention to remove the foreign body, and monitoring for any delayed complications. Accurate coding requires careful documentation of the injury mechanism, the presence of any foreign bodies, and the absence of thoracic cavity involvement.

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Need for precise documentation of the mechanism of injury
  • Differentiation between types of foreign bodies
  • Assessment of associated injuries (e.g., rib fractures, pneumothorax)
  • Potential for surgical intervention

Audit Risk Factors

  • Inadequate documentation of the mechanism of injury
  • Failure to note associated injuries
  • Incorrect coding of the type of foreign body
  • Lack of follow-up documentation for complications

Frequently Asked Questions

What is the difference between S21.142 and S21.141?

S21.142 refers to a puncture wound without penetration into the thoracic cavity, while S21.141 indicates that there is penetration into the thoracic cavity, which carries a higher risk of complications.
