Code Description

ICD-10 S02.413 is a billable code used to indicate a diagnosis of lefort iii fracture.

Key Diagnostic Point:

A LeFort III fracture is a type of craniofacial fracture that involves the separation of the facial skeleton from the cranial base. This fracture typically results from high-energy trauma, such as motor vehicle accidents, falls from heights, or physical assaults. The fracture pattern includes involvement of the zygomatic arch, maxilla, and nasal bones, leading to significant displacement and potential airway compromise. Clinically, patients may present with facial deformity, swelling, and ecchymosis, as well as possible neurological deficits due to associated head injuries. Diagnosis is primarily made through imaging studies, including CT scans, which provide detailed visualization of the fracture lines and any associated injuries. Management often requires surgical intervention to realign the facial structures and stabilize the fracture, with careful monitoring for complications such as infection, malocclusion, or further neurological impairment. Accurate coding for LeFort III fractures is essential for appropriate treatment planning and reimbursement.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Requires understanding of craniofacial anatomy and injury mechanisms.
  • Differentiation from other types of facial fractures.
  • Potential for associated injuries complicating the clinical picture.
  • Need for precise documentation of fracture type and location.

Audit Risk Factors

  • Inadequate documentation of the mechanism of injury.
  • Failure to specify associated injuries or complications.
  • Misclassification of fracture type.
  • Lack of detailed operative reports for surgical cases.

Frequently Asked Questions

What is the primary mechanism of injury for a LeFort III fracture?

LeFort III fractures typically result from high-energy trauma, such as motor vehicle accidents or severe physical assaults.

How can I differentiate between LeFort fractures?

LeFort I fractures involve the maxilla, LeFort II fractures involve the maxilla and nasal bones, while LeFort III fractures involve complete separation of the facial skeleton from the cranial base.
