Poisoning by opium, undetermined, initial encounter

This code signifies an adverse health event resulting from exposure to opium, where the intent (e.g., accidental, intentional self-harm, assault) cannot be determined by the provider. The patient is in the acute phase of treatment for the poisoning.

Apply this code when a patient presents with symptoms of opium toxicity, and the medical record does not clearly specify whether the exposure was accidental, intentional, or due to assault. This is appropriate for the initial visit or encounter for this specific poisoning event.

• Always assign an additional code for the manifestation of the poisoning.
• Do not use this code if the intent of the poisoning is known (e.g., accidental, intentional self-harm).
• Ensure documentation supports "undetermined" intent for opium exposure.
