Other specified infestations

This code signifies an infestation by an arthropod or other external parasite that is not specifically classified elsewhere in the ICD-10-CM system. It covers parasitic conditions that are clearly identified but do not have a more precise code available. This includes infestations by less common or unusual ectoparasites.

Apply this code when documentation specifies an infestation by an organism like chiggers (Trombiculidae), leeches (Hirudinea), or other non-specified external parasites. It is appropriate when the type of infestation is known but lacks a dedicated, more specific ICD-10-CM code. Ensure the medical record clearly identifies the infesting organism.

• Do not use this code if a more specific code for the identified infestation exists (e.g., lice, scabies, myiasis).
• Always review the medical record for the specific type of parasite to ensure the most precise code is selected.
• Consider an additional code for associated symptoms or complications (e.g., dermatitis, secondary infection) if documented.
