Poisoning by opium, intentional self-harm, initial encounter

This code signifies a patient presenting with adverse effects from opium, where the substance was deliberately taken with the intent to cause self-harm. This diagnosis indicates the initial phase of treatment for such an event.

Apply this code when documenting an overdose or toxic reaction to opium resulting from a suicide attempt or other intentional self-inflicted injury. It is appropriate for the initial hospital visit or encounter where the poisoning is first evaluated and treated.

• Always assign an additional code for the specific manifestation of the poisoning (e.g., coma, respiratory depression).
• Ensure documentation clearly supports intentional self-harm; differentiate from accidental or assault.
• This "A" suffix indicates an initial encounter; subsequent care for the same poisoning event will require different seventh characters.
