Chronic radiodermatitis

This code represents a persistent inflammatory skin reaction resulting from prolonged or repeated exposure to ionizing radiation. It signifies a long-term dermatological complication, distinct from acute radiation effects, characterized by skin changes like atrophy, fibrosis, telangiectasias, and pigmentary alterations.

Apply this code for patients presenting with documented chronic skin damage directly attributable to therapeutic or occupational radiation exposure. Documentation should clearly indicate the chronicity of the condition, often years after initial radiation, and describe the characteristic skin changes.

• Differentiate from acute radiodermatitis (L58.0) which is a short-term reaction.
• Always sequence this code after the underlying condition for which radiation therapy was administered, if still relevant.
• Ensure documentation specifies "chronic" or describes long-standing radiation-induced skin changes to support this diagnosis.
