Radiodermatitis (L58)

ICD-10 code L58 covers radiodermatitis, a skin condition caused by exposure to radiation. It includes specific codes for acute radiodermatitis (L58.0), chronic radiodermatitis (L58.1), and unspecified cases (L58.9), helping healthcare providers accurately document skin reactions due to radiation therapy.

These codes are used to classify skin disorders resulting from radiation exposure, often seen as side effects of radiotherapy. Acute radiodermatitis (L58.0) refers to early-stage skin inflammation and damage, sometimes called early radiation dermatitis or disorder of skin due to radiotherapy. Chronic radiodermatitis (L58.1) relates to long-term skin changes like radiation alopecia and chronic phototoxic dermatitis, reflecting ongoing or late effects of ionizing radiation. The unspecified code (L58.9) is for cases where the exact timing or nature of the radiation-induced skin condition is unclear but still recognized as radiation dermatitis. Using these distinct codes helps in precise healthcare documentation and supports better patient management.

Instructional Notations

Use Additional Code

The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.
