Insect bite (nonvenomous) of anus, initial encounter

This code signifies a non-poisonous insect bite affecting the perianal region or anus. It indicates the very first time this specific injury is being treated or evaluated by a healthcare provider.

Apply this code when a patient presents with symptoms such as itching, redness, or swelling localized to the anal area, and the history confirms a nonvenomous insect bite as the cause. This is appropriate for the initial visit for diagnosis and treatment of the bite.

• Ensure documentation clearly specifies a nonvenomous insect bite and the anal/perianal location.
• Confirm this is the patient's first encounter for this particular injury; subsequent encounters will require a different seventh character.
• Do not use for bites from venomous insects (e.g., spiders, scorpions) or for allergic reactions without a documented bite.
