Insect bite (nonvenomous) of anus, sequela

This code signifies a nonvenomous insect bite affecting the anal region, presenting as a sequela. It indicates that the acute phase of the bite has passed, and the patient is experiencing a residual condition or complication directly attributable to the original injury.

Apply this code when documenting a patient presenting with a chronic or late-effect condition resulting from a past nonvenomous insect bite to the anus. Examples include persistent pruritus, scarring, or chronic dermatitis at the bite site that is no longer in the acute healing phase.

• Always sequence this code after the code for the specific sequela (e.g., L90.5 for scar conditions).
• Ensure documentation clearly links the current condition to a previous nonvenomous insect bite of the anus.
• Verify that the bite is explicitly documented as nonvenomous; otherwise, a different code category would apply.
