Insect bite (nonvenomous), left foot, subsequent encounter

This code indicates a nonvenomous insect bite located on the patient's left foot. It specifies that the patient is receiving follow-up care for this injury, meaning the initial treatment has already occurred.

Use this code when a patient presents for a follow-up visit related to a nonvenomous insect bite on their left foot. This could include wound checks, dressing changes, or evaluation of healing progress after the initial encounter.

• Always confirm the laterality (left foot) and the type of bite (nonvenomous insect).
• Ensure the encounter is indeed subsequent to the initial treatment for the bite.
• Pair with an external cause code (e.g., W57.XXXD) to fully describe the circumstances of the injury.
