Other disorders of skin and subcutaneous tissue related to radiation (L59)

ICD-10 code L59 covers various skin and subcutaneous tissue disorders caused by radiation exposure. These codes help identify specific conditions resulting from different types of radiation injury to the skin, including heat and ionizing radiation effects.

This section includes L59.0, which codes for erythema ab igne (also known as dermatitis ab igne or heat-induced dermatosis), a skin condition caused by prolonged heat exposure. L59.8 encompasses other specified radiation-related skin disorders like poikiloderma, telangiectasia, scars from radiotherapy, and contact dermatitis caused by X-rays, sometimes linked to rare syndromes such as RIDDLE syndrome. L59.9 is used when the skin disorder related to radiation is unspecified and may include conditions like sun-damaged facial skin or ultraviolet sensitivity. These codes enable precise documentation for cases where radiation, including medical treatments or environmental exposure, leads to distinct skin complications, supporting accurate diagnosis and treatment planning.

Clinical Terms

The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.

Erythema Ab Igne

A cutaneous finding caused by prolonged heat exposure (e.g., space heater) and local heat injury (e.g., caused by LASER THERAPY). It is characterized by epidermal atrophy, reticular hyperpigmentation, and telangiectatic dermatosis.

Laser Therapy

The use of photothermal effects of LASERS to coagulate, incise, vaporize, resect, dissect, or resurface tissue.
