Code Description

ICD-10 S21.211 is a billable code used to indicate a diagnosis of laceration without foreign body of right back wall of thorax without penetration into thoracic cavity.

Key Diagnostic Point:

S21.211 refers to a laceration located on the right back wall of the thorax that does not involve any foreign body and does not penetrate the thoracic cavity. This type of injury typically results from blunt or sharp trauma, such as falls, accidents, or assaults. Clinically, it is important to assess the extent of the laceration, as well as to rule out associated injuries such as rib fractures, pneumothorax, or hemothorax. The absence of penetration into the thoracic cavity is crucial, as it indicates that vital structures such as the lungs and major blood vessels remain intact. Management may include wound care, suturing, and monitoring for complications. In cases where there is concern for underlying injuries, imaging studies such as chest X-rays or CT scans may be warranted. Proper documentation of the injury's location, depth, and any associated injuries is essential for accurate coding and billing.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Need for precise anatomical location documentation
  • Differentiation from similar codes (e.g., penetrating injuries)
  • Assessment of associated injuries (e.g., rib fractures)
  • Potential for complications requiring additional coding

Audit Risk Factors

  • Inadequate documentation of injury specifics
  • Failure to document associated injuries
  • Misclassification of the type of laceration
  • Inconsistent coding practices among providers
