Schmorl's nodes, thoracolumbar region

This code identifies Schmorl's nodes affecting the thoracolumbar spine. Schmorl's nodes are herniations of the intervertebral disc's nucleus pulposus through the cartilaginous endplate into the adjacent vertebral body. While often asymptomatic, they can be associated with back pain, particularly if acute or if they contribute to vertebral body edema.

Assign this code when diagnostic imaging (e.g., X-ray, MRI) confirms the presence of Schmorl's nodes specifically within the thoracolumbar spinal region. Documentation should clearly state the location of these nodes. This code is appropriate whether the nodes are an incidental finding or are considered a contributing factor to the patient's symptoms.

• Ensure the documentation specifies "thoracolumbar region" to accurately assign this code, as other spinal regions have distinct codes.
• Do not confuse Schmorl's nodes with other types of disc herniations or vertebral body abnormalities.
• Consider sequencing this code after a pain diagnosis (e.g., M54.5) if the Schmorl's nodes are documented as contributing to the patient's back pain.
