Toxic effect of unsp pesticide, intentional self-harm, init

This code signifies a patient presenting with adverse effects from an unknown pesticide, where the exposure was deliberately self-inflicted. The "initial encounter" indicates the patient is receiving active treatment for the acute poisoning.

Apply this code when documentation clearly states a pesticide poisoning of unknown type, the intent was self-harm (e.g., suicide attempt), and the patient is in the initial phase of treatment. This is appropriate for emergency department visits or initial hospital admissions for such an event.

• Ensure documentation explicitly states "unspecified pesticide" and "intentional self-harm."
• Verify the encounter is the first for this specific poisoning event; subsequent care would use a different encounter character.
• Do not use if the pesticide type is known or if the intent was accidental or assault.
