Poisoning by alpha-adrenoreceptor antagonists, assault, init

This code signifies an adverse health event resulting from the intentional administration of an alpha-adrenoreceptor antagonist (e.g., prazosin, tamsulosin) with the intent to harm. The patient is experiencing the initial effects or complications of this poisoning.

Apply this code when documentation clearly indicates a patient has been poisoned by an alpha-blocker due to an assault. This would include scenarios where the substance was forcibly given or administered without consent with malicious intent, and the patient is presenting for initial evaluation and treatment.

• Always verify the intent of the poisoning; "assault" must be explicitly documented or clearly inferred.
• Ensure the substance is specifically an alpha-adrenoreceptor antagonist.
• Confirm this is the patient's first encounter for this specific poisoning event.
