Poisoning by ecstasy, undetermined, subsequent encounter

This code indicates a patient presenting for follow-up care or treatment of adverse effects resulting from ecstasy (MDMA) poisoning, where the intent of the poisoning (e.g., accidental, intentional self-harm, assault) cannot be determined. It signifies that the initial acute phase of the poisoning has passed, and the patient is now receiving ongoing management.

Apply this code when a patient is seen for a subsequent visit related to ecstasy poisoning, and documentation does not specify whether the poisoning was accidental, intentional, or due to assault. This includes appointments for monitoring organ damage, managing withdrawal symptoms, or addressing long-term psychological effects after the initial emergency treatment.

• Always ensure documentation clearly states "undetermined" intent for the poisoning.
• This code is for subsequent encounters; use the appropriate initial encounter code for the first visit.
• Code any associated physical or psychological manifestations of the poisoning separately.
