Insect bite of left eyelid and periocular area, sequela

This code signifies a lasting effect or complication resulting from a nonvenomous insect bite on the left eyelid or the surrounding periocular tissues. It indicates that the acute phase of the bite has passed, and the patient is now experiencing a residual condition directly attributable to that past injury. Examples include scarring, chronic inflammation, or persistent disfigurement.

Apply this code when documentation clearly states a sequela (e.g., scar, chronic dermatitis, ectropion) of a previous nonvenomous insect bite affecting the left eyelid or periocular area. This code is appropriate for follow-up encounters addressing these long-term effects, not the initial acute bite. The patient's medical record should specify the causal link between the insect bite and the current condition.

• Always sequence the sequela code first, followed by a code describing the specific nature of the sequela (e.g., L90.5 for scar).
• Ensure the documentation explicitly states "sequela" or describes a chronic condition resulting from a past insect bite.
• Do not use this code for acute insect bites; refer to codes in the T14.8-T14.9 range for current injuries.
