This code signifies a harmful reaction resulting from direct contact with an unknown venomous animal. The nature of the exposure (intentional, accidental, or assault) is not specified or documented. This code is used for the initial phase of treatment for such an event.

Apply this code when a patient presents with symptoms of envenomation, but the specific type of venomous animal responsible for the contact cannot be identified. This is appropriate for the initial visit where the patient is being evaluated and treated for the acute effects of the toxic exposure.

• Only use this code when the venomous animal is truly unspecified in the medical record.
• Ensure the "A" for initial encounter is appended for the first time the patient is seen for this condition.
• Do not use if the type of venomous animal is known or suspected; instead, use a more specific T63.x code.
