Poisoning by ecstasy, assault, subsequent encounter

This code signifies a patient presenting for follow-up care or treatment of complications arising from an intentional overdose or adverse reaction to ecstasy (MDMA), where the substance was administered by another person with intent to harm. The patient is no longer in the acute phase of the poisoning.

Use this code for patients returning to the clinic or hospital for ongoing management of organ damage, psychological sequelae, or other persistent issues directly attributable to an ecstasy poisoning that occurred as an assault. This applies to situations such as follow-up appointments for cardiac monitoring, mental health counseling, or rehabilitation services after the initial acute care.

• Always assign an external cause code (e.g., Y07.-) to fully describe the circumstances of the assault.
• Ensure documentation clearly states the encounter is for follow-up care and not the initial treatment of the poisoning.
• Verify that the poisoning was explicitly documented as an assault, not accidental or self-inflicted.
