Myiasis

Myiasis is a parasitic infestation of the body of a living mammal by fly larvae (maggots) that feed on the host's necrotic or living tissue. This condition can affect various parts of the body, including skin, wounds, and body cavities, leading to tissue destruction and potential secondary infections.

This code is used when documentation explicitly states a diagnosis of myiasis, indicating an infestation by fly larvae. It applies to cases where the larvae are found in or on the patient's tissues, regardless of the specific fly species or anatomical location, as long as it's not specified as a particular type of myiasis.

• Ensure documentation clearly identifies the condition as myiasis; avoid using this code for other parasitic infestations.
• If the type of myiasis (e.g., cutaneous, wound, ocular) is specified, review other codes within the 134 category for a more specific option.
• Code any associated infections or complications (e.g., cellulitis, abscess) separately, following sequencing guidelines.
