Adolescent idiopathic scoliosis, cervicothoracic region

This code signifies a lateral curvature of the spine, of unknown origin, that manifests during adolescence and primarily affects the cervical and thoracic spinal segments. It is characterized by a three-dimensional deformity involving vertebral rotation in addition to lateral deviation.

Apply this code when documentation specifies adolescent idiopathic scoliosis with the apex of the curve located within the cervicothoracic region (C7-T1 or T1-T2). This diagnosis is typically made after ruling out congenital, neuromuscular, or other secondary causes of scoliosis.

• Ensure the documentation explicitly states "idiopathic" and "adolescent" to differentiate from other types of scoliosis.
• Verify the specific spinal region involved; this code is only for cervicothoracic involvement.
• Do not use this code if the scoliosis is congenital, neuromuscular, or due to a known underlying condition; use the appropriate secondary scoliosis code instead.
