Toxic effect of arsenic and its compounds, self-harm, init

This code signifies a patient presenting with adverse health effects resulting from the deliberate ingestion or exposure to arsenic or its compounds, with the explicit intent of self-harm. The patient is in the initial phase of receiving active treatment for this poisoning.

Apply this code when documenting the initial presentation and treatment of a patient who has intentionally poisoned themselves with arsenic, such as in a suicide attempt. This includes cases where the patient is admitted for detoxification, supportive care, or psychiatric evaluation following the self-inflicted exposure.

• Ensure documentation clearly states the intentional nature of the arsenic exposure (e.g., "suicide attempt," "self-poisoning").
• Confirm this is the first encounter for this specific poisoning episode; subsequent encounters would use a different seventh character.
• Always code additional symptoms or manifestations of arsenic toxicity (e.g., acute kidney injury, cardiac arrhythmias) separately.
