Erythema ab igne [dermatitis ab igne]
ICD-10 L59.0 is a billable code used to indicate a diagnosis of erythema ab igne [dermatitis ab igne].
Erythema ab igne, also known as dermatitis ab igne, is a skin condition characterized by a localized erythematous rash that arises due to prolonged exposure to heat sources, such as hot water bottles, heating pads, or direct contact with hot surfaces. Clinically, it presents as a reticular or net-like pattern of erythema, often accompanied by a burning sensation or pruritus. The condition primarily affects the skin's superficial layers, particularly in areas where heat is applied repeatedly. Over time, chronic exposure can lead to skin atrophy, pigmentation changes, and in severe cases, the development of skin lesions resembling burns. Diagnosis is primarily clinical, based on the characteristic appearance and history of heat exposure. Differential diagnoses include other forms of dermatitis, such as contact dermatitis or psoriasis, which may require further investigation. It is essential for healthcare providers to recognize this condition to prevent unnecessary treatments and to educate patients on avoiding heat exposure to mitigate symptoms.

L59.0 specifically covers erythema ab igne, which is caused by prolonged exposure to heat sources. It does not include other forms of dermatitis or skin conditions that may have similar presentations.
L59.0 should be used when the erythema is specifically due to heat exposure. If the dermatitis is caused by allergens or irritants without heat exposure, other codes such as L30.9 or L23.9 should be considered.
Documentation should include a detailed patient history of heat exposure, clinical findings of the rash, and any symptoms experienced by the patient. Photographic evidence may also be beneficial.
