Insect bite of unsp eyelid and periocular area, sequela

This code signifies a lasting effect or complication resulting from a nonvenomous insect bite on an unspecified eyelid or the surrounding periocular region. This could include residual scarring, chronic inflammation, or persistent discoloration that occurred after the initial bite healed. It indicates that the acute phase of the insect bite has passed, and the patient is now experiencing a long-term consequence.

Use this code when documentation clearly indicates a sequela (e.g., scar, chronic dermatitis, pigmentary changes) directly attributable to a past nonvenomous insect bite affecting the eyelid or periocular area. This code is appropriate when the patient presents for treatment or evaluation of these long-term effects, not the initial bite itself. Supporting documentation should specify the nature of the sequela and its causal link to the prior insect bite.

• Always sequence the sequela code first, followed by a code describing the specific nature of the sequela (e.g., L90.5 for scar conditions).
• Ensure documentation explicitly states the condition is a "sequela" or "late effect" of a previous insect bite. Avoid using this code for acute or current insect bites.
• Differentiate from codes for current insect bites (e.g., T14.81XA) or other types of eyelid lesions not related to insect bites.
