About the L55–L59 Code Range
Radiation-related conditions can affect the skin and the tissue beneath it. They include sunburn, other changes from ultraviolet radiation, and reactions to ionizing radiation.
The categories separate these conditions by type and exposure. L55 divides sunburn by degree. L56 groups other acute ultraviolet-related changes by the type of skin response. L57 identifies skin changes from chronic exposure to nonionizing radiation. L58 divides radiodermatitis, skin inflammation caused by ionizing radiation, into acute and chronic forms. L59 holds other radiation-related disorders of the skin and tissue beneath it.
