Poisoning by beta-adrenocpt antagonists, undetermined, subs

This code signifies a patient presenting for follow-up care related to an adverse event caused by beta-blocker medication, where the intent of the poisoning (e.g., accidental, intentional self-harm, assault) cannot be determined. The patient is no longer in the acute phase of treatment but is receiving ongoing management for the effects of the poisoning.

Apply this code when a patient is seen for continued monitoring, medication adjustments, or management of residual symptoms stemming from a beta-adrenoreceptor antagonist poisoning. This is appropriate for encounters occurring after the initial treatment of the acute poisoning, when the circumstances surrounding the poisoning remain unclear.

• Always assign an additional code for any associated manifestations or complications of the poisoning.
• Ensure documentation clearly supports a "subsequent encounter" and that the intent of the poisoning is explicitly noted as "undetermined."
• Do not use this code for initial acute care of the poisoning; instead, use the appropriate "initial encounter" code.
