Poisoning by MAO inhib antidepressants, accidental, init

This code signifies an accidental overdose or toxic exposure to monoamine oxidase inhibitor (MAOI) antidepressants. Patients may present with symptoms ranging from mild to severe, including hypertension, hyperthermia, seizures, and coma, resulting from an unintentional ingestion or misadministration of these medications.

This includes situations where a patient mistakenly takes another person's MAOI medication or misreads dosage instructions.

• Ensure documentation clearly states the poisoning was accidental or unintentional.
• Verify that the substance involved is specifically an MAOI antidepressant.
• This "A" suffix indicates the initial encounter for this poisoning episode.
