Insect bite (nonvenomous) of scalp, subsequent encounter

This code signifies a nonvenomous insect bite affecting the scalp, specifically when the patient is receiving follow-up care for the initial injury. This includes conditions like localized irritation, itching, or minor inflammation resulting from the bite, after the initial treatment has been rendered.

Apply this code for patients presenting for subsequent evaluation or treatment of a nonvenomous insect bite to the scalp. Documentation should clearly indicate that this is not the initial encounter for the injury, and specify the scalp as the affected body region.

• Ensure documentation specifies "subsequent encounter" and the nonvenomous nature of the bite.
• Distinguish from initial encounters (use appropriate 7th character 'A') or sequelae (use 7th character 'S').
• Do not use for bites from venomous insects; refer to codes for toxic effects or specific venomous insect bites.
