ICD-10: L59.0

Erythema ab igne, also known as dermatitis ab igne, is a skin condition characterized by a localized area of erythema (redness) and hyperpigmentation that results from prolonged exposure to heat, typically without direct contact with flames. This condition is often seen in individuals who are frequently exposed to heat sources, such as those who sit near fireplaces, heating pads, or other sources of intense heat.

Clinical Description

Etiology

Erythema ab igne occurs due to the thermal injury to the skin, which leads to a series of inflammatory responses. The heat exposure causes damage to the superficial layers of the skin, resulting in increased blood flow and the characteristic redness. Over time, the affected area may develop a brownish discoloration due to the deposition of melanin as a response to the injury.

Symptoms

The primary symptoms of erythema ab igne include:
- Redness: The affected area typically appears red and inflamed.
- Hyperpigmentation: Following the initial redness, the skin may develop a darker pigmentation, which can persist even after the heat exposure has ceased.
- Itching or Burning Sensation: Some individuals may experience mild itching or a burning sensation in the affected area.

Diagnosis

Diagnosis of erythema ab igne is primarily clinical, based on the history of heat exposure and the characteristic appearance of the skin. A thorough examination by a healthcare provider is essential to differentiate it from other dermatological conditions that may present similarly, such as contact dermatitis or other forms of dermatitis.

Treatment

Management of erythema ab igne involves:
- Avoidance of Heat Sources: The most effective treatment is to eliminate exposure to the heat source that caused the condition.
- Topical Treatments: In some cases, topical corticosteroids may be prescribed to reduce inflammation and discomfort.
- Monitoring: Regular follow-up may be necessary to monitor the condition, especially if hyperpigmentation persists.

ICD-10 Code

The ICD-10-CM code for erythema ab igne is L59.0. This code falls under the category of "Other disorders of skin and subcutaneous tissue" and is specifically designated for cases of dermatitis ab igne. It is important for healthcare providers to accurately document this condition using the appropriate ICD-10 code for billing and medical record purposes[1][2][3].

Conclusion

Erythema ab igne is a preventable skin condition resulting from thermal exposure, and understanding its clinical features, diagnosis, and management is crucial for effective treatment. By recognizing the signs and symptoms early, individuals can take steps to avoid further skin damage and seek appropriate care.
