Code Description

ICD-10 M43.05 is a billable code used to indicate a diagnosis of spondylolysis, thoracolumbar region.

Key Diagnostic Point:

Spondylolysis is a defect or fracture in the pars interarticularis of the vertebra, commonly occurring in the lumbar and thoracolumbar regions. This condition can lead to instability of the spine and is often associated with low back pain, particularly in adolescents and young adults involved in sports. The thoracolumbar region, which includes the junction between the thoracic and lumbar spine, is particularly susceptible due to the biomechanical stresses placed on it during activities such as lifting, twisting, and high-impact sports. Symptoms may include localized pain, muscle spasms, and, in some cases, neurological symptoms if nerve roots are affected. Diagnosis typically involves imaging studies such as X-rays, MRI, or CT scans to visualize the defect. Treatment options range from conservative management, including physical therapy and pain management, to surgical interventions such as spinal fusion, particularly in cases where conservative measures fail to alleviate symptoms or when there is significant spinal instability.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in presentation and symptoms among patients
  • Need for precise imaging documentation
  • Differentiation from other spinal conditions like spondylolisthesis
  • Potential for co-existing spinal deformities

Audit Risk Factors

  • Inadequate documentation of imaging results
  • Failure to document conservative treatment attempts
  • Misclassification with other spinal disorders
  • Lack of detailed symptom description

Frequently Asked Questions

What is the primary cause of spondylolysis?

Spondylolysis is often caused by repetitive stress or trauma to the spine, particularly in athletes involved in sports that require frequent bending and twisting.
