Other secondary scoliosis, lumbar region

This code signifies an abnormal lateral curvature of the spine in the lumbar region that is not congenital or idiopathic, but rather develops as a consequence of another underlying condition. This secondary curvature is typically compensatory or structural, arising from issues such as leg length discrepancy, neuromuscular disorders, or tumors.

Use this code when documentation clearly indicates scoliosis in the lumbar spine that is a direct result of an identifiable primary condition. This applies when the scoliosis is acquired and not present at birth or of unknown origin. Supporting documentation should specify the lumbar region and the secondary nature of the scoliosis.

• Always code the underlying primary condition causing the secondary scoliosis first, followed by this code.
• Distinguish carefully between idiopathic scoliosis (M41.1-) and secondary scoliosis; documentation must explicitly state the secondary nature.
• Ensure the documentation specifies "lumbar region" to use this specific code; other spinal regions have different codes.
