Schmorl's nodes, lumbar region

This code signifies the presence of Schmorl's nodes specifically located in the lumbar spine. Schmorl's nodes are protrusions of the intervertebral disc cartilage through the vertebral body endplate, often appearing as indentations on imaging. They are typically asymptomatic but can sometimes be associated with back pain.

Use this code when diagnostic imaging (e.g., X-ray, MRI) confirms the presence of Schmorl's nodes in the lumbar region. Documentation should clearly state the finding and its location. This code is appropriate whether the nodes are an incidental finding or are being investigated as a potential cause of lumbar back pain.

• Do not use this code if the Schmorl's nodes are located in other spinal regions (e.g., thoracic).
• Code any associated back pain separately, linking it to the Schmorl's nodes if causality is documented.
• Ensure the documentation specifies "lumbar region" to support the use of this specific code.
