Poisoning by MAO inhib antidepressants, self-harm, subs

This code signifies a patient presenting for follow-up care after intentionally self-poisoning with an antidepressant belonging to the monoamine oxidase inhibitor (MAOI) class. This indicates a prior acute event of deliberate overdose with this specific type of medication, and the current encounter is for ongoing management or monitoring related to that incident.

Use this code for encounters where a patient is being seen for complications, follow-up, or ongoing treatment directly related to a prior intentional MAOI antidepressant overdose. This includes visits for monitoring organ function, managing residual symptoms, or addressing psychiatric sequelae following the acute poisoning event.

• Ensure the encounter is for a subsequent visit, not the initial acute poisoning presentation.
• Verify the antidepressant involved was specifically an MAOI; other antidepressant classes have different codes.
• Confirm the intent was self-harm; accidental poisonings or adverse effects have different coding pathways.
