Insect bite, nonvenomous of face, neck, and scalp except eye, infected

This code signifies a localized inflammatory reaction on the face, neck, or scalp resulting from a non-venomous insect bite, where a secondary bacterial infection has developed. It indicates that the initial bite site has become infected, presenting with signs such as erythema, warmth, pain, or purulent discharge.

Use this code when documentation clearly states a non-venomous insect bite on the specified anatomical areas, and there is explicit mention of infection at the bite site. This typically applies to conditions like impetiginized insect bites or cellulitis secondary to an insect bite.

• Ensure the documentation specifies "nonvenomous" and the exact anatomical location (face, neck, or scalp, excluding the eye).
• Look for terms like "infected," "secondary infection," "cellulitis," or "impetigo" associated with the bite.
• Do not use for bites that are merely inflamed or irritated without evidence of bacterial infection.
