Infantile idiopathic scoliosis, lumbosacral region

This code signifies an abnormal lateral curvature of the spine, specifically in the lumbosacral region, that develops before the age of three years without an identifiable cause. It represents a structural spinal deformity presenting in infancy, affecting the lower back and sacrum.

Apply this code when documentation clearly indicates a diagnosis of idiopathic scoliosis in a child under three years old, with the curvature localized to the lumbar and/or sacral spine. Supporting documentation should include the patient's age at diagnosis and the specific spinal region affected.

• Ensure the patient's age at diagnosis is explicitly documented as under three years to differentiate from juvenile or adolescent idiopathic scoliosis.
• Confirm the scoliosis is idiopathic; exclude secondary causes such as congenital anomalies, neuromuscular conditions, or trauma.
• Verify the lumbosacral region is specifically identified as the primary site of the curvature.
