Poisoning by beta-adrenocpt antag, accidental, sequela

This code indicates a long-term effect or complication arising from an accidental overdose or exposure to beta-adrenoreceptor antagonists (beta-blockers). These sequelae are persistent conditions that occur after the acute phase of the poisoning has resolved. Examples include chronic cardiac dysfunction, persistent bradycardia, or other lasting organ damage attributed to the initial beta-blocker toxicity.

Apply this code when documenting a patient presenting with a current condition or symptom that is a direct, lasting consequence of a past, unintentional beta-blocker poisoning. This is appropriate for follow-up visits where the acute poisoning event is no longer active, but its residual effects are being managed. Do not use this code for the initial acute poisoning event itself.

• Always sequence this sequela code after the code(s) for the specific condition(s) resulting from the poisoning.
• Ensure documentation clearly links the current condition to a past accidental beta-blocker poisoning.
• Distinguish between acute poisoning (which would use an acute poisoning code) and the long-term effects (sequela).
