Insect bite (nonvenomous) of unspecified upper arm, sequela

This code signifies a lasting effect or complication resulting from a nonvenomous insect bite on an unspecified part of the upper arm. This could include chronic skin changes, scarring, persistent itching, or other long-term issues that developed after the initial bite healed.

Apply this code when documenting a patient presenting with a current condition that is a direct consequence of a past nonvenomous insect bite to the upper arm. This is appropriate for follow-up visits where the primary concern is the residual effect, rather than the acute bite itself.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., scar, dermatitis).
• Ensure documentation clearly links the current condition to a previous insect bite on the upper arm.
• Verify the bite was nonvenomous; if venomous, a different code series would be appropriate.
