Code Description

ICD-10 S02.31 is a billable code used to indicate a diagnosis of fracture of orbital floor, right side.

Key Diagnostic Point:

A fracture of the orbital floor, also known as a blowout fracture, occurs when there is a break in the bony structure of the orbital floor, typically due to blunt trauma. This injury often results from incidents such as falls, sports injuries, or physical altercations. The right side designation indicates that the fracture is localized to the right orbital floor. Clinically, patients may present with symptoms such as diplopia (double vision), enophthalmos (sunken eye), and periorbital edema. The mechanism of injury usually involves a sudden increase in intraorbital pressure, causing the thin bone of the orbital floor to fracture. Diagnosis is primarily through clinical examination and imaging studies, such as CT scans, which provide detailed visualization of the fracture and any associated injuries to the surrounding structures. Management may involve observation for minor fractures or surgical intervention for more severe cases, particularly if there is significant displacement or involvement of the ocular structures. Complications can include persistent diplopia, vision loss, and chronic pain if not properly addressed.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Need for precise documentation of laterality (right side)
  • Differentiation from other types of orbital fractures
  • Potential for associated injuries requiring additional coding
  • Variability in clinical presentation and management

Audit Risk Factors

  • Inadequate documentation of the mechanism of injury
  • Failure to specify laterality
  • Misclassification of the type of fracture
  • Lack of imaging documentation to support the diagnosis

Documentation Requirements

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

Common Clinical Scenarios

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

Billing Considerations

Ensure that all relevant symptoms and signs are documented to support the diagnosis.

Surgery

Documentation Requirements

Operative reports should detail the surgical approach, findings, and any repairs made to the orbital floor.
