Other secondary kyphosis, thoracic region

This code identifies an abnormal, excessive posterior curvature of the thoracic spine that is acquired or develops secondary to another condition, rather than being congenital or idiopathic. It signifies a humpback deformity in the upper to mid-back region that is not primary in nature.

Assign this code when documentation specifies a kyphotic deformity of the thoracic spine that has developed as a consequence of underlying conditions such as osteoporosis, vertebral fractures, degenerative disc disease, or neuromuscular disorders. Ensure the medical record clearly distinguishes it from congenital or adolescent kyphosis.

• Differentiate from primary kyphosis (e.g., Scheuermann's kyphosis) which has its own specific codes.
• Always code the underlying cause of the secondary kyphosis first, if known and actively treated.
• Ensure the documentation specifies the thoracic region; kyphosis in other spinal regions would use different codes.
