Postradiation kyphosis

This code describes an abnormal, excessive outward curvature of the spine (kyphosis) that develops as a direct consequence of radiation therapy. This condition typically results from radiation-induced damage to vertebral bodies, growth plates, or surrounding soft tissues, leading to structural weakening and subsequent spinal deformity.

Assign this code when documentation clearly indicates kyphosis that is directly attributed to prior radiation treatment, often for malignancies. This diagnosis is supported by a history of radiation therapy to the spine or adjacent areas, coupled with clinical or radiological evidence of kyphosis.

• Always sequence this code after the underlying malignancy (if still active) or personal history of malignancy, as it represents a late effect.
• Ensure documentation explicitly links the kyphosis to radiation exposure; avoid using for kyphosis from other etiologies.
• Consider additional codes for specific symptoms or complications related to the kyphosis, such as pain (M54.X) or neurological deficits (G99.2).
