Infantile idiopathic scoliosis, thoracic region

This code identifies an abnormal lateral curvature of the spine, specifically in the thoracic region, that develops in children from birth up to three years of age, without an identifiable underlying cause. It represents a structural spinal deformity that can progress with growth.

Apply this code when documentation confirms a diagnosis of idiopathic scoliosis in an infant, with the primary curve located in the thoracic spine. This diagnosis is typically made after ruling out congenital, neuromuscular, or syndromic causes of scoliosis.

• Ensure the patient's age at diagnosis falls within the infantile range (0-3 years).
• Verify documentation explicitly states "idiopathic" and specifies the "thoracic region" of the scoliosis.
• Distinguish from congenital scoliosis (Q67.5) or juvenile idiopathic scoliosis (M41.05), which affects older children.
