Code Description

ICD-10 S02.400 is a billable code used to indicate a diagnosis of malar fracture, unspecified side.

Key Diagnostic Point:

A malar fracture, also known as a zygomatic fracture, involves a break in the malar bone, which is a key component of the facial skeleton. This injury typically results from blunt trauma to the face, such as from falls, sports injuries, or physical altercations. Patients may present with facial swelling, bruising, and tenderness over the affected area, along with potential changes in facial symmetry. Diagnostic imaging, such as X-rays or CT scans, is essential for confirming the fracture and assessing its extent. Treatment may vary from conservative management with pain control and ice application to surgical intervention for more complex fractures. Complications can include malunion, nonunion, or aesthetic deformities, necessitating careful follow-up and management. Accurate coding is crucial for proper reimbursement and tracking of injury patterns in clinical settings.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in documentation of fracture specifics
  • Need for precise imaging interpretation
  • Potential for multiple facial fractures
  • Differentiation from other facial injuries

Audit Risk Factors

  • Inadequate documentation of injury mechanism
  • Failure to specify laterality when applicable
  • Misinterpretation of imaging results
  • Coding without supporting clinical evidence

Emergency Medicine

Documentation Requirements

Documentation must include mechanism of injury, clinical findings, and imaging results.

Common Clinical Scenarios

Patients presenting with facial trauma after a fall or sports injury.

Billing Considerations

Ensure that all relevant injuries are documented to avoid undercoding.

Surgery

Documentation Requirements

Operative reports must detail the surgical approach, findings, and any repairs performed.

Common Clinical Scenarios

Surgical intervention for complex malar fractures requiring fixation.

Billing Considerations

Document any complications or additional procedures performed during surgery.
