Code Description

ICD-10 S12.120 is a billable code used to indicate a diagnosis of other displaced dens fracture.

Key Diagnostic Point:

A displaced dens fracture refers to a fracture of the odontoid process (dens) of the second cervical vertebra (C2) that has resulted in a misalignment of the bone fragments. This type of fracture is often caused by high-energy trauma, such as motor vehicle accidents, falls from heights, or sports injuries. The dens is critical for the stability and rotation of the cervical spine, and its displacement can lead to significant neurological complications if not properly managed. Clinical presentation may include neck pain, limited range of motion, and neurological deficits depending on the severity of the injury. Diagnosis typically involves imaging studies such as X-rays, CT scans, or MRI to assess the fracture's displacement and any associated spinal cord injury. Management may range from conservative treatment with immobilization to surgical intervention, depending on the fracture's stability and the patient's overall condition. Complications can include nonunion, malunion, or neurological impairment, necessitating careful monitoring and follow-up.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in fracture presentation and severity
  • Need for precise imaging interpretation
  • Potential for associated neurological injuries
  • Differentiation from other cervical spine injuries

Audit Risk Factors

  • Inadequate documentation of the mechanism of injury
  • Failure to specify the type of fracture (displaced vs. non-displaced)
  • Lack of imaging reports to support the diagnosis
  • Misclassification of fracture type

Frequently Asked Questions

What is the primary cause of a displaced dens fracture?

Displaced dens fractures are primarily caused by high-energy trauma, such as motor vehicle accidents, falls, or sports injuries.

How is a displaced dens fracture diagnosed?

Diagnosis typically involves imaging studies like X-rays, CT scans, or MRIs to assess the fracture's displacement and any associated injuries.

What are the treatment options for a displaced dens fracture?

Treatment options may include conservative management with immobilization or surgical intervention, depending on the fracture's stability and the patient's neurological status.
