Poisoning by MAO inhib antidepressants, self-harm, init

This code signifies a patient presenting with an adverse physiological reaction due to an overdose of a monoamine-oxidase inhibitor (MAOI) antidepressant, where the ingestion was a deliberate act of self-harm. The patient is in the initial phase of treatment for this specific poisoning event.

Apply this code when documentation clearly indicates an MAOI antidepressant poisoning resulting from an intentional self-inflicted act. This is appropriate for the first encounter where the patient is receiving active treatment for the acute effects of the poisoning. Subsequent encounters for the same poisoning event would require a different seventh character.

• Always verify the specific class of antidepressant involved to ensure it is an MAOI.
• Confirm the intent was self-harm, not accidental or assault.
• Ensure this is the initial encounter for the poisoning; subsequent care for the same event requires a different seventh character (D or S).
