Poisoning by ecstasy, undetermined, initial encounter

This code signifies a case of poisoning due to ecstasy (MDMA) where the intent (e.g., accidental, intentional self-harm, assault) cannot be determined from the available documentation. The patient is in the active phase of treatment for the acute effects of the poisoning.

Apply this code when a patient presents with symptoms of ecstasy toxicity, and the medical record explicitly states or strongly implies that the circumstances surrounding the exposure are unknown or unclear. This is for the initial visit or encounter for this specific poisoning event.

• Ensure documentation clearly indicates "undetermined" intent for ecstasy poisoning.
• Always assign a secondary code for any associated manifestations of the poisoning (e.g., tachycardia, hyperthermia).
• Do not use this code for subsequent encounters related to the same poisoning; instead, use the appropriate subsequent encounter or sequela code.
