Wound myiasis

This code represents the infestation of a wound by fly larvae (maggots), a condition known as wound myiasis. The larvae feed on necrotic or living tissue within the wound, leading to tissue destruction and potential secondary infections. This is distinct from other forms of myiasis affecting different body sites.

Use this code when documentation clearly indicates the presence of maggot infestation specifically within an open wound, ulcer, or lesion. This typically occurs in patients with poor hygiene, neglected wounds, or those in endemic areas. Supporting documentation would include physician notes describing the visual identification of larvae in a wound.

• Differentiate from other forms of myiasis (e.g., cutaneous, ophthalmic) which have distinct codes.
• Always code the underlying wound or skin condition first, if applicable, as the primary diagnosis, followed by this code for the myiasis.
• Ensure documentation specifies "wound" myiasis; generalized or unspecified myiasis would use a different code.
