Insect bite (nonvenomous) of lip, initial encounter

This code describes a non-toxic insect bite affecting the lip, indicating the patient is receiving initial treatment for this specific injury. It distinguishes bites that do not involve venom from those that do, and specifies the anatomical location.

Apply this code when a patient presents for the first time with a localized reaction on the lip due to a non-venomous insect bite, such as from a mosquito, fly, or ant. This is appropriate for initial evaluation and management of symptoms like swelling, redness, or itching.

• Ensure the documentation clearly states the bite is non-venomous and located on the lip.
• Verify this is the patient's first encounter for this specific injury; subsequent encounters will require a different seventh character.
• Consider additional codes for any associated allergic reactions or secondary infections.
