Poisoning by opium, assault, initial encounter

This code signifies an intentional act of poisoning by opium, where the substance was administered to the patient by another individual with harmful intent. The "initial encounter" designation indicates that the patient is receiving active treatment for the acute effects of this poisoning.

This code is appropriate for documenting cases where a patient presents for treatment following an assault involving opium. This includes emergency department visits, inpatient admissions, or initial outpatient consultations for managing the immediate toxic effects of the opium.

• Always confirm the intent of the poisoning (assault vs. accidental, self-harm) through thorough documentation.
• Ensure documentation clearly states opium as the causative agent.
• Pair this code with external cause codes (e.g., Y09.-) to provide a complete picture of the circumstances.
