Adolescent idiopathic scoliosis, thoracic region

This code identifies a structural lateral curvature of the spine, specifically in the thoracic region, that develops during adolescence without an identifiable underlying cause. It is characterized by a three-dimensional deformity involving vertebral rotation in addition to lateral deviation.

Assign this code for patients aged 10 to 18 years diagnosed with idiopathic scoliosis primarily affecting the thoracic spine. Documentation should clearly state "idiopathic scoliosis" and specify the thoracic region, often confirmed by radiographic imaging.

• Ensure the patient's age falls within the adolescent range (typically 10-18 years) for "adolescent idiopathic scoliosis."
• Verify the documentation specifies the thoracic region; avoid using this code for lumbar or thoracolumbar involvement.
• Do not use this code for congenital, neuromuscular, or other secondary forms of scoliosis.
