Insect bite, nonvenomous of face, neck, and scalp except eye, without mention of infection

This code describes a non-venomous insect bite affecting the skin of the face, neck, or scalp, excluding the eye itself. It indicates a localized reaction to an insect bite without any signs or symptoms of secondary infection.

Use this code when documentation specifies a non-venomous insect bite (e.g., mosquito, flea, ant) on the face, neck, or scalp, and explicitly states or implies the absence of infection. This is appropriate for initial evaluations of simple bites presenting with localized erythema, pruritus, or swelling.

• Do not use if the bite is on or involves the eye; a more specific code for eye involvement would be necessary.
• If there is any mention of infection (e.g., cellulitis, impetigo), a secondary code for the infection should be added, or a different primary code may be more appropriate.
• Ensure the documentation clearly specifies the anatomical location (face, neck, or scalp) to differentiate from bites on other body regions.
