Insect bite (nonvenomous), left ankle, sequela

This code signifies a long-term or late-effect condition resulting from a nonvenomous insect bite on the patient's left ankle. It indicates that the initial injury has resolved, but residual symptoms, complications, or sequelae persist.

Apply this code when documenting a patient presenting with a current condition directly attributable to a past nonvenomous insect bite on their left ankle. Examples include chronic pruritus, scarring, hyperpigmentation, or persistent localized dermatitis at the bite site, occurring after the acute phase of the bite has passed.

• Always sequence this sequela code after the code for the specific residual condition (e.g., L90.5 for scar conditions).
• Ensure documentation clearly links the current left ankle sequela to a prior nonvenomous insect bite.
• Do not use for acute insect bites; those require codes from the T14.8-T14.9 series.
