Toxic effect of rattlesnake venom, self-harm, init

This code signifies a patient presenting with symptoms resulting from rattlesnake venom, where the exposure was deliberately self-inflicted with the intent to cause harm. The "initial encounter" designation indicates that this is the first time the patient is receiving active treatment for this specific poisoning episode.

Apply this code when documentation clearly states a patient intentionally sought out and allowed a rattlesnake to bite them, or otherwise self-administered rattlesnake venom, as a form of self-harm. This is appropriate for the initial hospital visit or first encounter with a healthcare provider for the acute management of the venom's effects.

• Always sequence this code as the primary diagnosis when the self-harm is the reason for the encounter.
• Requires an additional code for the specific type of rattlesnake venom (e.g., from category T63.01-).
• Remember to add external cause codes (X71.-) to fully describe the intent and circumstances of the self-harm.
