Unspecified kyphosis, thoracic region

This code signifies an abnormal, forward curvature of the spine in the thoracic region, where the specific cause or type of kyphosis has not been documented by the provider. It indicates a dorsal hump or roundback deformity without further diagnostic specificity.

Apply this code when the medical record clearly states "kyphosis of the thoracic spine" but lacks details regarding its etiology (e.g., postural, Scheuermann's, congenital, post-traumatic). This code is appropriate when the provider has not specified whether the kyphosis is primary, secondary, or due to a particular underlying condition.

• Avoid using this code if the documentation specifies the type of kyphosis (e.g., M40.0XX for postural kyphosis).
• Always query the provider for greater specificity if possible, as more specific codes exist for various types and causes of kyphosis.
• Do not use this code if the kyphosis is congenital; refer to codes in Chapter 17 (Congenital malformations, deformations and chromosomal abnormalities).
