Insect bite (nonvenomous), right foot, sequela

This code signifies a current health problem resulting from a past, nonvenomous insect bite on the patient's right foot. It indicates that the initial injury has resolved, but the patient is still experiencing a residual effect or complication directly attributable to that bite.

Use this code when documenting a patient presenting with a chronic condition, scar, deformity, or other long-term sequela on their right foot, and the medical record clearly links this condition to a previously sustained nonvenomous insect bite. Examples include chronic dermatitis, hyperpigmentation, or a persistent nodule at the bite site, occurring months or years after the initial bite.

• Always sequence this sequela code first, followed by a code for the specific nature of the sequela (e.g., L81.0 for postinflammatory hyperpigmentation).
• Ensure the documentation explicitly states the laterality (right foot) and the nonvenomous nature of the original insect bite.
• Confirm that the current condition is a direct consequence of the past bite and not an acute or new injury.
