Poisoning by caffeine, intentional self-harm, subs encntr

This code signifies a patient presenting for follow-up care or treatment of complications arising from an intentional overdose of caffeine. The self-harm act has already occurred, and the current encounter addresses ongoing issues related to the initial poisoning event.

Apply this code when a patient returns for a clinic visit after being discharged from an emergency department for a caffeine overdose, or when they are admitted for ongoing management of cardiac arrhythmias or other organ damage resulting from a deliberate caffeine ingestion. It is appropriate for subsequent hospitalizations or outpatient visits directly related to the initial self-harm attempt.

• Always sequence this code after the primary diagnosis for the specific condition being treated during the subsequent encounter (e.g., cardiac arrhythmia).
• Ensure documentation clearly indicates "intentional self-harm" and that the encounter is not for the initial acute poisoning.
• Verify that the substance involved is explicitly documented as caffeine.
