Miliaria profunda
ICD-10 L74.2 is a billable code used to indicate a diagnosis of miliaria profunda.
Miliaria profunda, commonly referred to as heat rash or prickly heat, is a skin condition that occurs when sweat glands become blocked, leading to the retention of sweat beneath the skin. This condition typically presents as small, red, itchy bumps or blisters, often in areas where sweat accumulates, such as the back, chest, and neck. The anatomy involved includes the eccrine sweat glands, which are responsible for thermoregulation through sweat production. Disease progression can vary; while it may resolve spontaneously with cooling and avoidance of heat, persistent cases can lead to secondary infections or chronic irritation. Diagnostic considerations include a thorough clinical examination and patient history, particularly regarding exposure to heat and humidity, as well as any prior episodes of miliaria. Differential diagnoses may include other dermatological conditions such as folliculitis or contact dermatitis, necessitating careful evaluation to ensure accurate diagnosis and management.

L74.2 specifically covers miliaria profunda, which is characterized by deep-seated vesicles and papules due to sweat retention. It is important to differentiate it from other types of miliaria, such as L74.0 and L74.1, which involve superficial sweat gland blockage.
L74.2 should be used when the clinical presentation indicates deeper sweat gland involvement, particularly when the patient exhibits symptoms of miliaria profunda. Accurate differentiation from other miliaria types is crucial for appropriate coding.
Documentation should include a detailed clinical examination, patient history regarding exposure to heat, and any previous episodes of miliaria. Photographic evidence may also support the diagnosis, along with treatment notes indicating the management approach.
