Myiasis of other sites

This code signifies an infestation of human or animal tissue by the larvae of dipterous flies (maggots) occurring in anatomical locations other than those specified by more specific myiasis codes. It represents a parasitic infection where fly larvae feed on the host's living or necrotic tissue, body fluids, or ingested food.

Apply this code when documentation confirms myiasis affecting sites such as the urinary tract, eyes, ears, or internal organs, and more specific myiasis codes (e.g., cutaneous, nasopharyngeal) are not applicable. Supporting documentation should clearly identify the presence of fly larvae and the affected "other" anatomical site.

• Ensure the documentation explicitly states the myiasis is not cutaneous, wound, ocular, nasopharyngeal, or genitourinary to justify "other sites."
• Always code the specific type of myiasis if a more precise ICD-10-CM code exists for the documented anatomical location.
• Consider an additional code for any associated symptoms or complications (e.g., infection, tissue necrosis) if documented.
