Aural myiasis

This code signifies the infestation of the human ear canal or middle ear by fly larvae (maggots). This parasitic condition, also known as ear myiasis, can cause symptoms such as pain, itching, discharge, and hearing loss. The larvae feed on living or necrotic tissue within the ear.

Apply this code when documentation confirms the presence of fly larvae within the patient's external auditory canal or middle ear. This diagnosis is typically made upon direct visualization of the maggots during otoscopic examination. Supporting documentation will include physician notes detailing the identification of larvae and the affected ear.

• Specify laterality (e.g., right ear, left ear, bilateral) using appropriate seventh characters.
• Do not confuse with other parasitic infestations of the ear, such as scabies, which would be coded differently.
• Consider co-coding with codes for any associated complications, such as otitis externa or perforation of the tympanic membrane.
