Toxic effect of venom of tarantula, self-harm, init

This code signifies a harmful physiological reaction resulting from exposure to tarantula venom, specifically when the exposure was deliberately self-inflicted. The "initial encounter" designation indicates that this is the first time the patient is receiving active treatment for this particular poisoning. Symptoms can range from localized pain and swelling to more systemic effects depending on the species and amount of venom.

Apply this code when documentation clearly states a patient intentionally exposed themselves to tarantula venom, such as in a suicide attempt or self-harm incident. This code is appropriate for the initial visit where the patient is being evaluated and treated for the acute toxic effects. Subsequent care for the same poisoning would require a different encounter character.

• Always verify the intent of the exposure; "intentional self-harm" must be explicitly documented.
• Ensure the venom source is specifically identified as a tarantula.
• Pair this code with an external cause code (e.g., X20.0XXA for contact with venomous spiders, intentional self-harm) to provide a complete picture of the incident.
