Poisoning by ecstasy, undetermined, sequela

This code indicates a long-term health condition or complication resulting from a past poisoning by ecstasy (MDMA). The original poisoning event's intent (e.g., accidental, intentional self-harm) could not be determined at the time. This code is used when the acute phase of the ecstasy poisoning has passed, and the patient is now experiencing residual effects.

Use this code when documenting conditions such as chronic neurological damage, persistent psychiatric disorders, or organ damage (e.g., liver, kidney) that are directly attributed to a previous ecstasy poisoning where the intent was unknown. This applies to follow-up encounters for these lasting effects, not the initial acute poisoning.

• Always assign a sequela code (ending in 'S') for conditions that are residual effects of a previous injury or poisoning.
• Do not use this code for the acute phase of ecstasy poisoning; use the appropriate acute poisoning code.
• Ensure documentation clearly links the current condition to a past ecstasy poisoning with undetermined intent.
