Code Description

ICD-10 S02.402 is a billable code used to indicate a diagnosis of zygomatic fracture, unspecified side.

Key Diagnostic Point:

A zygomatic fracture, also known as a cheekbone fracture, occurs when there is a break in the zygomatic bone, which is a key component of the facial skeleton. This type of fracture can result from various mechanisms of injury, including blunt trauma from falls, sports injuries, or assaults. Symptoms typically include facial swelling, bruising, pain, and potential changes in facial symmetry. Patients may also experience difficulty with eye movement or vision if the fracture affects the orbit. Diagnosis is primarily through clinical examination and imaging studies such as X-rays or CT scans to assess the extent of the fracture and any associated injuries. Management may involve conservative treatment with pain control and ice application, or surgical intervention in cases of significant displacement or functional impairment. Complications can include malunion, infection, or persistent pain. Accurate coding is essential for proper reimbursement and tracking of injury patterns.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in clinical presentation and severity of fractures
  • Need for precise documentation of injury mechanism
  • Potential for associated injuries requiring additional codes
  • Differentiation from other facial fractures

Audit Risk Factors

  • Inadequate documentation of the mechanism of injury
  • Failure to specify laterality when applicable
  • Misclassification of fracture type or severity
  • Omission of associated injuries or conditions

Documentation Requirements

Documentation must include a detailed account of the mechanism of injury, clinical findings, and any imaging results.

Common Clinical Scenarios

Patients presenting with facial trauma after a fall or altercation.

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 made.

Frequently Asked Questions

What is the difference between S02.402 and S02.401?

S02.402 is used for unspecified zygomatic fractures, while S02.401 specifies a fracture on the right side. Accurate documentation of laterality is crucial for correct coding.
