Code Description

ICD-10 S13.180 is a billable code used to indicate a diagnosis of subluxation of c7/t1 cervical vertebrae.

Key Diagnostic Point:

Subluxation of the C7/T1 cervical vertebrae refers to a partial dislocation of the seventh cervical vertebra (C7) and the first thoracic vertebra (T1). This condition can occur due to trauma, such as a fall, motor vehicle accident, or sports injury, where excessive force is applied to the neck. The subluxation can lead to nerve compression, resulting in pain, weakness, or sensory changes in the upper extremities. Clinically, patients may present with neck pain, restricted range of motion, and neurological symptoms depending on the severity of the subluxation. Diagnosis typically involves a thorough physical examination and imaging studies, such as X-rays or MRI, to assess the alignment of the vertebrae and any associated soft tissue injuries. Management may include conservative treatment options like physical therapy, pain management, and in some cases, surgical intervention to realign the vertebrae and relieve nerve compression. 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

  • Variability in presentation and severity of symptoms
  • Need for precise imaging interpretation
  • Potential for associated injuries requiring additional coding
  • Differentiation from other cervical spine injuries

Audit Risk Factors

  • Inadequate documentation of the mechanism of injury
  • Failure to document neurological assessments
  • Misinterpretation of imaging results
  • Coding without confirming the specific vertebrae involved

Frequently Asked Questions

What is the difference between subluxation and dislocation?

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