Poisoning by beta-adrenocpt antagonists, assault, sequela

This code signifies a long-term health condition or complication resulting from an intentional overdose or exposure to beta-blocker medications, where the poisoning was inflicted by another person. It indicates that the acute phase of the poisoning has passed, and the patient is now experiencing residual effects.

Apply this code when documenting a patient presenting with chronic symptoms or sequelae directly attributable to a past assault involving beta-adrenoreceptor antagonists. This would include conditions like persistent bradycardia, heart block, or other organ damage that developed as a consequence of the poisoning. It should be used after the initial acute poisoning has been treated and the patient is in a follow-up or long-term care setting.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela (e.g., I44.2 for atrioventricular block).
• Ensure documentation clearly links the current condition to the past assaultive beta-blocker poisoning.
• Verify that the encounter is for the management of the residual effects, not the acute poisoning event.
