Thoracogenic scoliosis, thoracic region

This code describes a lateral curvature of the spine in the thoracic region that is secondary to a thoracic condition or procedure. It signifies scoliosis that has developed as a consequence of issues originating within the chest cavity, rather than being idiopathic or congenital.

Apply this code when documentation clearly indicates scoliosis in the thoracic spine resulting from a prior thoracic surgery, trauma, infection, or other non-spinal thoracic pathology. This diagnosis is supported by imaging studies showing thoracic scoliosis and a documented history linking it to a thoracic etiology.

• Ensure the documentation explicitly states the thoracic region of the scoliosis.
• Always code the underlying thoracic condition or procedure that caused the scoliosis first, if still active or relevant.
• Differentiate from idiopathic scoliosis (M41.1-) or other specified types of scoliosis.
