Other acariasis

This code represents infestations by mites other than those causing scabies (Sarcoptes scabiei) or demodicosis (Demodex species). These acariases can manifest with various dermatological symptoms, including pruritus, papules, vesicles, or secondary infections, depending on the specific mite involved.

This code is appropriate for documenting mite infestations of the skin that are not specified as scabies or demodicosis. It should be used when the physician's documentation clearly identifies an acariasis caused by a mite other than Sarcoptes scabiei or Demodex. Examples include infestations by chiggers (Trombiculidae), bird mites, or straw itch mites.

• Ensure documentation specifies "other acariasis" or identifies a specific mite species not covered by 133.0 (scabies) or 133.1 (demodicosis).
• Avoid using this code if the documentation simply states "mite infestation" without further specificity; query the provider for clarification.
• Consider sequencing this code as the primary diagnosis if the acariasis is the reason for the encounter, or as a secondary diagnosis if it's a co-existing condition.
