Poisoning by beta-adrenocpt antagonists, accidental, subs

This code signifies an accidental overdose or adverse reaction to a beta-blocker during a subsequent encounter for treatment. The patient is experiencing ongoing effects or complications from an unintentional ingestion or administration of a beta-adrenoreceptor antagonist.

Apply this code when a patient presents for follow-up care, monitoring, or management of persistent symptoms or complications stemming from an accidental beta-blocker poisoning. This includes situations where the initial acute event has passed, but the patient requires continued medical attention for the poisoning's effects.

• Ensure the documentation clearly states the poisoning was accidental and that this is not the initial encounter for the event.
• Always code with an external cause code (e.g., X44.-) to specify the circumstances of the poisoning.
• Consider additional codes for specific manifestations or complications of the beta-blocker poisoning.
