Prickly heat

This code represents miliaria, a common dermatological condition characterized by an itchy rash of small, raised papules or vesicles, typically caused by blocked sweat ducts. It occurs when sweat is trapped beneath the skin, leading to inflammation and irritation.

Use this code when documentation indicates a diagnosis of prickly heat, heat rash, or miliaria. This condition is often seen in hot, humid environments or in individuals who are overdressed or have fever. The diagnosis is typically made clinically based on the characteristic rash and history of heat exposure.

• Differentiate from other forms of dermatitis; this code is specific to miliaria caused by heat and blocked sweat ducts.
• Do not use for general skin irritation or allergic reactions unless specifically diagnosed as miliaria.
• Consider additional codes for any underlying conditions contributing to excessive sweating, if applicable.
