Code Description

ICD-10 S12.390 is a billable code used to indicate a diagnosis of other displaced fracture of fourth cervical vertebra.

Key Diagnostic Point:

A displaced fracture of the fourth cervical vertebra (C4) is a serious injury that can result from various mechanisms, including trauma from motor vehicle accidents, falls, or sports injuries. The cervical vertebrae are critical for supporting the skull and protecting the spinal cord. A displaced fracture indicates that the bone fragments have moved out of their normal alignment, which can lead to spinal cord injury, nerve damage, and significant neurological deficits. Clinical presentation may include neck pain, limited range of motion, and neurological symptoms such as weakness, numbness, or paralysis in the upper or lower extremities. Diagnosis typically involves imaging studies such as X-rays, CT scans, or MRIs to assess the fracture's extent and any associated spinal cord injury. Management may include conservative treatment with immobilization or surgical intervention to stabilize the spine and decompress the spinal cord if necessary. Complications can include chronic pain, neurological deficits, and the potential for further injury if not properly managed.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Need for precise documentation of fracture type and displacement
  • Differentiation from similar codes for other cervical vertebra fractures
  • Potential for associated neurological injuries requiring additional coding
  • Variability in treatment approaches affecting coding for follow-up care

Audit Risk Factors

  • Inadequate documentation of the mechanism of injury
  • Failure to specify the type of fracture (displaced vs. non-displaced)
  • Misalignment with surgical or treatment codes
  • Inconsistent documentation of neurological assessments

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 following trauma, requiring immediate imaging and assessment.

Billing Considerations

Ensure that all relevant details about the injury mechanism and neurological findings are documented to support coding.

Surgery

Documentation Requirements

Operative reports must detail the surgical approach, findings, and any complications encountered during the procedure.

Common Clinical Scenarios

Surgical intervention for stabilization of the C4 vertebra following a traumatic injury.

Billing Considerations

Accurate coding requires clear documentation of the surgical procedure and any associated diagnoses.

Frequently Asked Questions

What is the difference between S12.390 and S12.391?

S12.390 refers to a displaced fracture of the fourth cervical vertebra, while S12.391 refers to a non-displaced fracture. Accurate documentation of the fracture type is essential for correct coding.
