Poisoning by angiotens-convert-enzyme inhibtr, undet, init

This code signifies an adverse event resulting from exposure to an ACE inhibitor, where the intent of the exposure (e.g., accidental, intentional self-harm, assault) cannot be determined by the provider. The patient is presenting for the initial treatment of the poisoning.

Apply this code when a patient presents with signs and symptoms of ACE inhibitor toxicity, and the medical record does not clearly indicate whether the poisoning was accidental, intentional, or due to an assault. This code is appropriate for the first visit or admission for this specific poisoning event.

• Always sequence this code first if it is the primary reason for the encounter.
• Do not use this code if the intent of the poisoning is known (e.g., accidental, intentional self-harm); instead, select the appropriate intent character.
• Ensure documentation supports the "undetermined" intent and the "initial encounter" for treatment.
