Insect bite of middle front wall of thorax, sequela

This code signifies a lasting effect or complication resulting from a nonvenomous insect bite on the central anterior chest wall. This could include chronic skin changes, scarring, or persistent irritation that developed after the initial bite healed. The "sequela" aspect indicates that the acute injury has passed, but its residual effects are still present.

Use this code when documenting a patient presenting with a chronic condition directly attributable to a nonvenomous insect bite on the middle front wall of the thorax. This applies to follow-up visits where the primary concern is the long-term consequence of the bite, such as hyperpigmentation, keloid formation, or chronic dermatitis at the bite site.

• Always assign a secondary code to specify the exact nature of the sequela (e.g., L90.5 for scar conditions).
• Ensure documentation clearly links the current condition to a past nonvenomous insect bite on the specified anatomical location.
• Do not use this code for acute insect bites; those require codes from the initial encounter categories.
