Insect bite (nonvenomous) of nose, initial encounter

This diagnosis code signifies a skin lesion on the nose resulting from a non-venomous insect bite. It indicates an inflammatory reaction or localized skin irritation caused by the insect, without the introduction of toxins. This code is specifically for the initial presentation and treatment of the bite.

Apply this code when a patient presents with a documented insect bite on the nose, and the bite is explicitly stated as non-venomous. Supporting documentation would include physician notes detailing the location of the bite, the non-venomous nature of the insect (or lack of venomous symptoms), and that this is the first time the patient is being seen for this specific injury.

• Ensure documentation specifies "nonvenomous" to differentiate from venomous bites (e.g., spider, scorpion).
• Verify the bite location is specifically the nose; other facial areas would require different codes.
• The "X A" seventh character indicates an initial encounter, meaning the patient is receiving active treatment for the bite.
