Code Description

ICD-10 S21.01 is a billable code used to indicate a diagnosis of laceration without foreign body of breast.

Key Diagnostic Point:

S21.01 refers to a laceration of the breast that does not involve any foreign body. This type of injury can occur due to various mechanisms, including blunt trauma, sharp force trauma, or surgical interventions. The breast is a sensitive area that can be affected by trauma leading to lacerations, which may vary in severity from superficial cuts to deep wounds that could involve underlying structures such as muscle or connective tissue. In cases of chest trauma, it is crucial to assess for associated injuries, such as rib fractures, pneumothorax, or hemothorax, which can complicate the clinical picture. Proper evaluation and management are essential to prevent complications, including infection or significant blood loss. Documentation should include the mechanism of injury, depth of the laceration, and any associated injuries to ensure accurate coding and appropriate treatment planning.

Medium Complexity

Complexity Factors

  • Differentiating between superficial and deep lacerations
  • Assessing for associated injuries (e.g., rib fractures, pneumothorax)
  • Documenting the mechanism of injury accurately
  • Understanding the implications of surgical interventions

Audit Risk Factors

  • Inadequate documentation of the mechanism of injury
  • Failure to document associated injuries
  • Misclassification of the depth of the laceration
  • Lack of clarity on whether a foreign body is present
