Toxic effect of unsp snake venom, assault, init encntr

This code signifies a patient presenting with adverse health effects resulting from exposure to an unknown type of snake venom, where the exposure was intentionally inflicted by another person. The "initial encounter" designation indicates that this is the first time the patient is receiving active treatment for this specific poisoning.

This code is appropriate for documenting the initial phase of care for a patient who has been deliberately bitten by an unidentified snake. It should be used when the intent of the bite is determined to be an assault and the specific snake species is not yet known or documented.

• Always sequence this code first when it represents the primary reason for the encounter.
• Requires an external cause code (e.g., X20.XXXA for contact with venomous snakes and lizards, initial encounter) to fully describe the circumstances of the assault.
• Do not use if the snake species is identified; instead, use a more specific T63.0XX code.
