Miliaria rubra
ICD-10 L74.0 is a billable code used to indicate a diagnosis of miliaria rubra.
Miliaria rubra, commonly known as heat rash or prickly heat, is a dermatological condition characterized by the obstruction of sweat ducts, leading to the accumulation of sweat beneath the skin. Clinically, it presents as small, red, itchy papules or vesicles, often accompanied by a burning sensation. The condition typically occurs in hot, humid environments, particularly in individuals who sweat excessively or wear tight clothing. The anatomy involved includes the epidermis and the sweat glands, particularly the eccrine glands, which are responsible for thermoregulation. Disease progression can vary; while mild cases may resolve spontaneously with cooling measures, more severe cases can lead to secondary infections if not managed properly. Diagnostic considerations include a thorough clinical examination and patient history to differentiate miliaria rubra from other skin conditions such as folliculitis or contact dermatitis. Treatment primarily focuses on alleviating symptoms through cooling the skin, wearing loose clothing, and avoiding excessive heat exposure.

L74.0 specifically covers miliaria rubra, which is characterized by red, itchy papules due to blocked sweat glands. It does not include other forms of miliaria, such as miliaria crystallina (L74.1) or miliaria profunda (L74.2).
L74.0 should be used when the clinical presentation is consistent with miliaria rubra, particularly when the rash is red and itchy, and there is a clear history of heat exposure. If the rash is clear and vesicular, L74.1 may be more appropriate.
Documentation should include a detailed patient history, physical examination findings, and any relevant environmental factors contributing to the condition. Notes on treatment provided and patient response can also support the use of this code.
