L58.9
ICD-10-CMThis code describes inflammation of the skin caused by exposure to ionizing radiation, without further specification of the type or severity. It encompasses a broad range of skin reactions, from mild erythema to more severe ulceration or necrosis, when the specific nature of the radiodermatitis is not documented.
This code is appropriate for documenting a diagnosis of radiodermatitis when the medical record does not provide sufficient detail to classify it as acute, chronic, or another specific type. It is used when the physician's documentation simply states "radiodermatitis" or "radiation dermatitis" without further elaboration.
