Insect bite (nonvenomous), left lower leg, sequela

This code signifies a lasting effect or complication resulting from a nonvenomous insect bite on the patient's left lower leg. This could include chronic skin changes, persistent scarring, or ongoing localized symptoms directly attributable to the original bite, occurring after the acute phase of the injury has passed.

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 lower leg. Examples include chronic pruritus, hyperpigmentation, or a keloid scar at the bite site. This code is appropriate for follow-up visits addressing these long-term sequelae.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., L90.5 for scar conditions).
• Ensure documentation clearly links the current condition to a previous nonvenomous insect bite on the left lower leg.
• The "S" seventh character indicates sequela, meaning the residual effect of a past injury, not the acute injury itself.
