Insect bite (nonvenomous) of left hand, sequela

This code signifies a lasting effect or complication resulting from a nonvenomous insect bite on the left hand. It indicates that the acute phase of the bite has passed, but the patient is still experiencing a residual condition directly attributable to the original injury. Examples include chronic scarring, persistent dermatitis, or nerve damage.

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 left hand. This is appropriate for follow-up visits addressing long-term issues, not for the initial bite or its immediate acute treatment.

• Always sequence this code after the code for the specific sequela being treated (e.g., L90.5 for scar conditions).
• Ensure documentation clearly links the current condition to the previous insect bite on the left hand.
• Do not use for acute insect bites; those require codes from the initial encounter categories.
