Insect bite (nonvenomous) of l bk wl of thorax, sequela

This code indicates a long-term or late-effect condition resulting from a nonvenomous insect bite located on the left posterior aspect of the chest wall. This could include persistent scarring, chronic dermatitis, or nerve damage that developed after the initial bite healed.

Use this code when documenting a patient presenting with a current condition that is a direct consequence of a past nonvenomous insect bite on the left back wall of the thorax. This applies when the acute phase of the bite has resolved, and the current issue is a residual effect.

• Always sequence this code after the code for the specific sequela (e.g., scar, dermatitis).
• Ensure documentation clearly links the current condition to a previous nonvenomous insect bite.
• Verify the laterality (left) and anatomical site (back wall of thorax) are precisely documented.
