Toxic effect of venom of tarantula, undetermined, sequela

This code signifies a long-term health problem or complication arising from a tarantula venom exposure where the intent (e.g., accidental, intentional self-harm, assault) of the exposure is not documented or cannot be determined. It indicates that the acute phase of the toxic effect has passed, and the patient is now experiencing residual symptoms or conditions directly attributable to the past envenomation.

Apply this code when a patient presents with a chronic condition, such as persistent neurological deficits, skin changes, or organ damage, that is definitively linked to a prior tarantula bite. This is appropriate when the initial toxic event occurred in the past, and the current encounter is for the management of these lasting effects, and the circumstances of the original bite are unknown.

• Only use this code for sequelae; do not use for acute toxic effects.
• Ensure documentation clearly links the current condition to a past tarantula envenomation.
• This "S" seventh character indicates sequela and should be used for complications or conditions arising as a direct result of the initial toxic effect.
