Poisoning by alpha-adrenocpt antagonists, self-harm, init

This diagnosis code signifies a deliberate act of self-poisoning involving medications that block alpha-adrenergic receptors. These drugs are commonly used to treat conditions such as hypertension, benign prostatic hyperplasia, or anxiety, and an overdose can lead to severe cardiovascular and neurological effects. The "initial encounter" designation indicates that the patient is receiving active treatment for the acute effects of the poisoning.

This code is appropriate for documenting cases where a patient has intentionally ingested an overdose of an alpha-blocker, such as prazosin, doxazosin, or tamsulosin, with the intent to harm themselves. It should be used during the initial phase of treatment, including emergency department visits, inpatient admissions for stabilization, or initial outpatient follow-up directly related to the acute poisoning event.

• Always sequence this code first if it is the primary reason for the encounter.
• Remember to also code any associated signs, symptoms, or complications resulting from the poisoning.
• Do not use this code for accidental poisonings or therapeutic underdosing; different codes apply for those scenarios.
