Poisoning by caffeine, accidental (unintentional), init

This code signifies an accidental or unintentional poisoning specifically due to caffeine. It indicates that the patient's adverse reaction to caffeine was not intended and is the primary reason for their initial presentation for treatment. This diagnosis is used when the caffeine exposure leads to a toxic effect requiring medical intervention.

Apply this code for patients presenting with symptoms of caffeine toxicity (e.g., severe tachycardia, arrhythmias, seizures, psychosis) following an accidental overdose of caffeine-containing products. This includes scenarios such as unintentional ingestion of excessive energy drinks, caffeine pills, or other highly caffeinated substances. It is appropriate for the initial encounter where the poisoning is first evaluated and treated.

• Ensure documentation clearly states "accidental" or "unintentional" and specifies caffeine as the causative agent.
• Confirm this is the initial encounter for this specific poisoning event; subsequent encounters would use a different seventh character.
• Do not use for adverse effects of caffeine taken as prescribed or for intentional self-harm; those require different codes.
