Poisoning by ecstasy, accidental (unintentional), sequela

This code signifies a long-term or residual effect resulting from an accidental overdose or exposure to ecstasy (MDMA). These sequelae are conditions that persist after the acute phase of the poisoning has resolved, such as chronic neurological deficits, psychiatric disorders, or organ damage.

Apply this code when documenting a patient presenting with a current health condition directly attributable to an unintentional ecstasy poisoning that occurred in the past. This is appropriate for follow-up visits addressing ongoing complications, rather than the initial acute poisoning event.

• Always sequence this code after the code(s) for the specific sequela being treated (e.g., chronic psychosis, liver damage).
• Ensure documentation clearly links the current condition to a past accidental ecstasy poisoning.
• Do not use for acute poisoning events; those require codes from the initial encounter or subsequent encounter categories.
