Poisoning by coronary vasodilators, undetermined, init

This code signifies an adverse event resulting from the intake of medications designed to widen coronary arteries, where the intent (e.g., accidental, intentional self-harm, assault) cannot be determined. The patient is presenting for the initial treatment of this poisoning.

Apply this code when a patient presents with symptoms of poisoning from coronary vasodilators, and the medical record does not specify whether the exposure was accidental, intentional, or due to assault. This is appropriate for the first encounter for this specific poisoning event.

• Always assign an additional code for the specific coronary vasodilator drug if known (from categories T36-T50).
• Do not use this code if the intent of the poisoning is clearly documented as accidental, intentional self-harm, or assault; instead, select the appropriate intent character.
• For subsequent encounters related to this poisoning, use the appropriate seventh character (D for subsequent, S for sequela).
