Code Description

ICD-10 S12.11 is a billable code used to indicate a diagnosis of type ii dens fracture.

Key Diagnostic Point:

A Type II dens fracture, also known as an odontoid fracture, occurs at the second cervical vertebra (C2), specifically at the dens, which is a bony projection that extends upward from the body of the vertebra. This type of fracture is characterized by a fracture through the base of the dens, which can lead to instability of the cervical spine and potential neurological compromise. Mechanisms of injury typically include high-energy trauma such as motor vehicle accidents, falls from heights, or sports-related injuries. Clinical presentation may include neck pain, restricted range of motion, and neurological symptoms if the spinal cord is affected. Diagnosis is primarily through imaging studies, including X-rays and MRI, to assess the fracture's location and any associated spinal cord injury. Management often involves immobilization with a cervical collar or halo vest, and in some cases, surgical intervention may be necessary to stabilize the fracture and prevent further complications. Complications can include nonunion of the fracture, neurological deficits, and chronic pain.

  • Misclassification of fracture type
  • Lack of imaging results in the medical record

Specialty Focus

Medical Specialties

Emergency Medicine

Documentation Requirements

Documentation must include a thorough assessment of the patient's neurological status, mechanism of injury, and imaging results.

Common Clinical Scenarios

Patients presenting with acute neck pain after trauma, requiring immediate imaging and evaluation.

Billing Considerations

Ensure that all relevant imaging studies are documented and that the mechanism of injury is clearly described.

Surgery

Documentation Requirements

Operative reports must detail the surgical approach, fixation methods, and any intraoperative findings.

Common Clinical Scenarios

Surgical intervention for unstable Type II dens fractures requiring stabilization.

Billing Considerations

Document the rationale for surgical intervention and any pre-existing conditions that may affect healing.
