Insect bite (nonvenomous) of unsp parts of thorax, sequela

This code signifies a lasting effect or complication resulting from a nonvenomous insect bite on an unspecified area of the thorax. It indicates that the acute phase of the bite has passed, and the patient is now experiencing a residual condition directly attributable to the original injury.

Use this code when documenting a chronic or late effect of a nonvenomous insect bite on the chest, back, or flank, where the specific location on the thorax is not documented. This would apply to conditions such as persistent scarring, chronic dermatitis, or nerve damage that developed as a direct consequence of the bite.

• Always assign an additional code to specify the nature of the sequela (e.g., L90.5 for scar conditions, L30.9 for unspecified dermatitis).
• Ensure documentation clearly links the current condition to a past nonvenomous insect bite on the thorax.
• Avoid using this code for acute insect bites; it is strictly for sequelae.
