Insect bite (nonvenomous), right knee, sequela

This diagnosis code indicates a lasting effect or complication resulting from a nonvenomous insect bite on the right knee. This is not for the initial acute injury, but rather for a condition that has developed as a direct consequence of the original bite, such as chronic dermatitis, scarring, or persistent pain.

Apply this code when documenting a patient presenting with a current condition that is a direct sequela of a past nonvenomous insect bite to their right knee. Examples include a patient with a keloid scar at the bite site or chronic pruritus localized to the right knee, clearly attributed to an old insect bite. Do not use for the initial treatment of an acute bite.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela (e.g., L90.5 for scar conditions).
• Ensure documentation clearly links the current condition to a previous nonvenomous insect bite on the right knee.
• Verify the laterality (right knee) is explicitly stated in the medical record.
