Insect bite of other specified part of neck, sequela

This code signifies a lasting effect or complication resulting from an insect bite on a specific, but not otherwise classified, area of the neck. This could include chronic scarring, persistent dermatitis, or nerve damage that developed after the initial acute injury. The "sequela" indicates that the acute phase of the insect bite has passed, and the current encounter addresses the long-term consequences.

Apply this code when a patient presents for treatment of a residual condition directly attributable to an insect bite on an unspecified part of the neck that occurred in the past. Documentation should clearly state the causal link between the prior insect bite and the current chronic symptom or condition. This code is appropriate for follow-up care of complications, not the initial acute injury.

• Always use an external cause code (W57.XXXA) in conjunction with this code to identify the insect responsible for the bite.
• Ensure documentation specifies "sequela" or a chronic condition resulting from the bite; otherwise, an acute bite code may be more appropriate.
• Distinguish from acute insect bites (S10.86XA) or subsequent encounters for acute bites (S10.86XD).
