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

This code signifies a patient presenting with adverse effects from an overdose of beta-blocker medication, where the overdose was deliberately self-inflicted. The patient is in the initial phase of treatment for this poisoning.

This code is appropriate for documenting cases of beta-blocker toxicity resulting from a suicide attempt or other intentional self-harm. It should be used when the patient is first seen for this specific poisoning event, such as in an emergency department or upon initial hospital admission.

• Always assign an additional code for the specific beta-blocker involved, if known (e.g., T44.71- for atenolol).
• Remember to use a seventh character of 'D' for subsequent encounters and 'S' for sequelae.
• Consider co-reporting with codes for underlying mental health conditions, if applicable, such as F20.- for schizophrenia or F32.- for major depressive disorder.
