Acariasis, unspecified

This code represents an infestation of the skin by mites, commonly known as acariasis, when the specific type of mite or the precise clinical manifestation is not documented. It indicates a general diagnosis of a mite infestation without further specification.

Use this code when the medical record clearly states "acariasis" or "mite infestation" but provides no additional details regarding the causative mite species (e.g., Sarcoptes scabiei) or the specific clinical syndrome (e.g., scabies). This code is appropriate when the physician's documentation is limited to an unspecified mite infestation.

• Avoid using this code if a more specific diagnosis, such as scabies (133.0), is documented.
• Query the provider for more specific documentation if "acariasis" is noted without further detail, to allow for more precise coding.
• This code should be used as a last resort when no other specific acariasis code can be assigned based on the available documentation.
