Poisoning by unsp antidepressants, assault, init encntr

This code signifies a patient presenting with adverse effects from an antidepressant, where the specific type of antidepressant is unknown. The poisoning was intentionally inflicted by another person, and this is the first time the patient is receiving treatment for this specific incident.

Apply this code when documentation clearly indicates an antidepressant overdose or adverse reaction due to an assault, but the medical record does not specify the particular antidepressant involved. This is appropriate for the initial hospital visit or emergency department encounter for such an event.

• Ensure documentation explicitly states "assault" as the intent of the poisoning.
• Only use for the initial encounter; subsequent care for the same poisoning event will require a different seventh character.
• If the specific antidepressant is identified, a more precise code from the T43.2- subcategory should be used.
