Insect bite (nonvenomous) of other part of head, sequela

This code signifies a nonvenomous insect bite affecting an unspecified or "other" part of the head, with the "S" indicating a sequela. This means the code is used for complications or conditions arising as a direct result of a previous insect bite, rather than the acute bite itself. Examples of sequelae might include scarring, chronic dermatitis, or persistent nerve damage.

Apply this code when documentation clearly indicates a long-term effect or complication stemming from a nonvenomous insect bite to a part of the head not specified by more granular codes (e.g., eyelid, nose, lip). The medical record must explicitly state the causal link between the prior bite and the current condition, and specify that the condition is a sequela.

• Always ensure the "S" (sequela) seventh character is appropriate; this code is not for acute bites.
• Confirm the insect bite was nonvenomous; differentiate from venomous bites (e.g., spider, scorpion).
• Prioritize more specific anatomical codes for the head if available (e.g., S00.16XS for eyelid, S00.36XS for nose).
