Poisoning by beta-adrenocpt antagonists, undet, sequela

This code signifies a long-term health problem or complication arising from a past poisoning event involving beta-adrenoreceptor antagonists (beta-blockers), where the intent of the poisoning (e.g., accidental, intentional self-harm, assault) could not be determined. The patient is no longer in the acute phase of the poisoning but is experiencing residual effects.

Use this code when documenting a chronic condition or persistent symptom directly attributable to a previous beta-blocker poisoning of undetermined intent. This applies when the acute poisoning event has resolved, but the patient continues to require care for its lasting consequences.

• This "S" seventh character indicates a sequela, meaning the patient is being treated for a residual effect of the poisoning, not the acute poisoning itself.
• Always sequence this code after the code(s) for the specific sequela being treated (e.g., cardiac arrhythmia, renal failure).
• Ensure documentation clearly links the current condition to the past beta-blocker poisoning and specifies the undetermined intent.
