Code Description

ICD-10 S13.140 is a billable code used to indicate a diagnosis of subluxation of c3/c4 cervical vertebrae.

Key Diagnostic Point:

Subluxation of the cervical vertebrae, specifically at the C3 and C4 levels, refers to a partial dislocation of these vertebrae in the cervical spine. This condition can result from trauma, such as a fall, motor vehicle accident, or sports injury, leading to misalignment of the vertebrae. Patients may present with neck pain, restricted range of motion, and neurological symptoms depending on the severity of the subluxation. The cervical spine is crucial for protecting the spinal cord and supporting the head, and any misalignment can lead to significant complications, including nerve impingement or spinal cord injury. Diagnosis typically involves a thorough clinical examination, imaging studies such as X-rays or MRI to assess the alignment and any associated soft tissue injuries. Management may include conservative treatment like physical therapy, chiropractic adjustments, or in severe cases, surgical intervention to realign the vertebrae and relieve pressure on the spinal cord or nerves.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Need for precise documentation of the mechanism of injury
  • Differentiation from complete dislocations or other cervical injuries
  • Potential for associated neurological deficits requiring additional coding
  • Variability in clinical presentation and treatment approaches

Audit Risk Factors

  • Inadequate documentation of the mechanism of injury
  • Failure to document associated neurological symptoms
  • Incorrect coding of the level of subluxation
  • Lack of imaging results in the medical record

Specialty Focus

Medical Specialties

Emergency Medicine

Documentation Requirements

Documentation must include a detailed account of the mechanism of injury, initial assessment findings, and any imaging results.

Common Clinical Scenarios

Patients presenting after a fall or motor vehicle accident with neck pain and limited mobility.

Billing Considerations

Ensure that all neurological assessments are documented to support the diagnosis and any potential complications.

Surgery

Documentation Requirements

Operative reports must detail the surgical approach, findings, and any corrective measures taken to address the subluxation.

Common Clinical Scenarios

Surgical intervention for severe subluxation with neurological compromise.

Billing Considerations

Document any pre-operative imaging and post-operative outcomes to support the coding of the surgical procedure.

Coding Guidelines

Inclusion Criteria

Frequently Asked Questions

What is the difference between subluxation and dislocation?

Subluxation refers to a partial dislocation where the joint surfaces are misaligned but still in contact, while dislocation indicates a complete separation of the joint surfaces.
