Other kyphosis, thoracic region

This code signifies an abnormal, exaggerated posterior curvature of the thoracic spine, not otherwise specified as postural or due to tuberculosis, congenital anomalies, or other specific causes. It represents a dorsal hump or rounding of the upper back that is more pronounced than normal physiological curvature.

Use this code when documentation indicates kyphosis of the thoracic region that is not further specified by type (e.g., postural, Scheuermann's) and is not congenital or post-traumatic. This code is appropriate when the physician's diagnosis explicitly states "other kyphosis, thoracic region" or similar non-specific terminology.

• Ensure the documentation clearly specifies the thoracic region; kyphosis in other spinal regions requires a different code.
• Distinguish this from M40.0- (postural kyphosis) or M40.1- (other secondary kyphosis) if the cause is known and documented.
• Always review for laterality or specific causes (e.g., congenital, post-traumatic) that would lead to a more specific code.
