Adolescent idiopathic scoliosis, lumbar region

This code signifies a lateral curvature of the spine in the lumbar region that develops during adolescence without an identifiable underlying cause. It is a structural deformity characterized by vertebral rotation and often presents with a visible asymmetry of the back.

Use this code for patients aged 10 to 18 years diagnosed with idiopathic scoliosis specifically affecting the lumbar spine. Documentation should clearly state "adolescent idiopathic scoliosis" and specify the "lumbar region" as the primary site of curvature.

• Ensure the patient's age falls within the adolescent range (typically 10-18 years) for "adolescent idiopathic" diagnoses.
• Verify documentation explicitly states "lumbar region" to differentiate from thoracic or thoracolumbar involvement.
• Do not use this code if a secondary cause for scoliosis (e.g., neuromuscular disease, congenital anomaly) is identified; instead, code the underlying condition.
