Insect bite (nonvenomous) of oral cavity, sequela

This code signifies a lasting effect or complication resulting from a nonvenomous insect bite to the oral cavity. It indicates that the acute injury has resolved, but the patient continues to experience a residual condition directly attributable to the original bite. Examples include chronic inflammation, scarring, or altered sensation within the mouth.

Use this code when documenting a patient presenting with a persistent issue in the oral cavity that is a direct consequence of a past nonvenomous insect bite. This applies after the initial bite has healed, but a sequela, such as a permanent lesion or functional impairment, remains. It should not be used for the acute phase of the bite.

• Always sequence this code after the code describing the specific sequela (e.g., a code for scarring or chronic inflammation).
• Ensure documentation clearly links the current condition to a previous nonvenomous insect bite of the oral cavity.
• Do not use for venomous bites; those have distinct coding pathways.
