Miliaria, unspecified

This code represents miliaria, commonly known as heat rash or prickly heat, where the specific type of miliaria (e.g., crystallina, rubra, profunda) is not documented or determined. It involves an inflammatory skin condition resulting from blocked sweat ducts, leading to trapped sweat within the epidermis or dermis.

Assign this code when the medical record clearly indicates a diagnosis of miliaria, but the provider has not specified the clinical subtype. This is appropriate when documentation simply states "heat rash" or "prickly heat" without further detail regarding the depth of obstruction.

• Avoid using this code if a more specific type of miliaria (e.g., L74.0, L74.1, L74.2) is documented.
• Query the provider for clarification if the documentation suggests a specific type but doesn't explicitly state it.
• This code typically represents a benign, self-limiting condition; consider associated symptoms or complications if present.
