Toxic effect of venom of caterpillars, accidental, sequela

This code signifies a lasting health problem or complication resulting from an accidental exposure to caterpillar venom. The initial toxic reaction has resolved, but the patient continues to experience residual effects. These sequelae can range from chronic skin conditions to persistent neurological symptoms.

Apply this code when documenting a patient presenting with a long-term, residual condition directly attributable to a past, unintentional caterpillar envenomation. This would include scenarios where the acute phase of the toxic reaction has passed, but the patient is still managing a related chronic issue.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic dermatitis, peripheral neuropathy).
• Ensure documentation clearly links the current condition to a past accidental caterpillar venom exposure.
• The "S" in the seventh character indicates sequela, meaning the late effects of the initial toxic event.
