Juvenile idiopathic scoliosis, lumbar region

This code signifies a lateral curvature of the spine in the lumbar region, originating before the age of 10, without a known underlying cause. It is a structural deformity that can progress during growth spurts.

Apply this code when documentation specifies idiopathic scoliosis diagnosed in a child or adolescent, with the primary curve located in the lumbar spine. Supporting documentation should include the patient's age at diagnosis (under 10 years old) and the absence of congenital, neuromuscular, or syndromic causes.

• Ensure the documentation explicitly states "idiopathic" and "juvenile" (onset before age 10) to differentiate from adolescent idiopathic scoliosis.
• Verify the specific spinal region (lumbar) is documented; do not use for thoracic or thoracolumbar curves.
• Code any associated pain or neurological symptoms separately, if documented.
