Insect bite (nonvenomous), right ankle, sequela

This code signifies a lasting effect or complication stemming from a nonvenomous insect bite on the patient's right ankle. It indicates that the initial injury has resolved, but a residual condition, such as scarring, chronic itching, or discoloration, persists.

Apply this code when documenting a current condition that is a direct consequence of a past nonvenomous insect bite to the right ankle. This is appropriate for follow-up visits addressing chronic issues related to the bite, rather than the acute bite itself.

• Always use an external cause code (e.g., W57.XXXA) in conjunction with this sequela code to identify the cause of the original injury.
• Ensure documentation clearly links the current ankle condition to a previous nonvenomous insect bite.
• Do not use this code for the initial encounter of an acute insect bite; use the appropriate acute injury code instead.
