Poisn by oth agents aff the cardiovasc sys, self-harm, init

This code signifies a patient presenting with adverse effects from self-administering a substance primarily impacting the heart and blood vessels, where the intent was to cause self-harm. The poisoning is due to an agent not specifically classified elsewhere within the T46 category.

Apply this code when documentation clearly indicates an intentional overdose or self-poisoning attempt using a cardiovascular-acting drug or substance not otherwise specified. This is for the initial encounter for treatment of the acute poisoning event. Examples include intentional overdose of an unlisted antiarrhythmic, antihypertensive, or other cardiac medication.

• Ensure the documentation explicitly states "intentional self-harm" or similar language indicating suicidal intent.
• Verify that the substance involved primarily affects the cardiovascular system and is not more specifically coded elsewhere in T46.
• This "A" suffix indicates the initial encounter for care; subsequent encounters for the same poisoning would use a different seventh character.
