Pediculosis, acariasis and other infestations (B85-B89)

ICD-10 codes B85 to B89 cover a wide range of parasitic infestations including lice (pediculosis), scabies, myiasis (fly larvae infestation), acariasis (mite infestations), and other specified or unspecified parasitic diseases. These codes help precisely identify infestations caused by various parasites affecting skin and other body parts.

This code range is used to classify conditions such as pediculosis capitis (head lice, also called infestation by Pediculus humanus capitis), pediculosis corporis (body lice or parasitic melanoderma), and phthiriasis (infestation by pubic lice or Phthirus pubis). The chapter also includes scabies (caused by Sarcoptes scabiei mite), which presents with intense itching and skin rash. Myiasis codes specify fly larvae causing cutaneous, wound, ocular, nasopharyngeal, aural, and other localized infestations. Moreover, the range covers acariasis, addressing various mite infestations such as grocer's itch and allergic reactions caused by house dust mites. Other arthropod infestations like ticks, bed bugs, and fleas also fall under this chapter, including tungiasis (sandflea infestation). Finally, it includes codes for unspecified infestations and parasitic diseases that may affect multiple organs or systems, providing comprehensive coding options for diverse parasitic infections.
