Poisoning by alpha-adrenocpt antagonists, undetermined, init

This code signifies an adverse event resulting from the ingestion or exposure to alpha-adrenoreceptor antagonists, where the intent (e.g., accidental, intentional self-harm, assault) cannot be determined by the provider. The patient is in the initial phase of treatment for this poisoning. Alpha-adrenoreceptor antagonists are medications primarily used to treat hypertension, benign prostatic hyperplasia, and pheochromocytoma.

Use this code when documentation indicates a patient is experiencing symptoms of poisoning from an alpha-adrenoreceptor antagonist, and the provider cannot ascertain whether the exposure was accidental, intentional, or due to assault. This code is appropriate for the initial encounter where the patient is actively being treated for the acute effects of the poisoning.

• Ensure documentation clearly states "undetermined" intent for the poisoning.
• Always assign an additional code for the specific manifestation(s) of the poisoning.
• This "A" seventh character is only for the initial encounter; subsequent encounters will require different seventh characters.
