Other secondary scoliosis, site unspecified

This code signifies a curvature of the spine that develops as a consequence of another underlying condition, rather than being a primary, idiopathic scoliosis. The specific location of the spinal curvature is not documented or is unknown. This diagnosis indicates a secondary form of scoliosis without a specified anatomical site.

This code is appropriate when documentation clearly states "secondary scoliosis" but lacks information regarding the specific spinal region affected (e.g., thoracic, lumbar). It is used when the etiology is known to be secondary (e.g., neuromuscular disease, congenital anomaly, trauma) but the precise spinal segment involved in the curvature is not specified.

• Avoid using this code if a more specific site of secondary scoliosis (e.g., thoracic, lumbar) is documented.
• Always code the underlying primary condition causing the secondary scoliosis first, if known.
• Do not confuse with idiopathic scoliosis codes (M41.1-).
