Other secondary scoliosis, thoracolumbar region

This code signifies a curvature of the spine in the thoracolumbar region (mid to lower back) that is not idiopathic but rather a consequence of another underlying condition. This secondary scoliosis can arise from neuromuscular disorders, congenital anomalies, trauma, or tumors affecting spinal integrity.

Apply this code when documentation clearly indicates scoliosis in the thoracolumbar spine that is secondary to a known cause, such as cerebral palsy, muscular dystrophy, or a spinal tumor. Supporting documentation should specify both the region of the scoliosis and the primary condition responsible for its development.

• Always code the underlying primary condition first, followed by this code for the secondary scoliosis.
• Distinguish carefully from idiopathic scoliosis (M41.1-) or congenital scoliosis (Q67.5).
• Ensure the documentation specifies the thoracolumbar region; otherwise, a more general secondary scoliosis code might be appropriate.
