Poisoning by other narcotics, assault, initial encounter

This code signifies an intentional overdose or harmful exposure to a narcotic substance, other than heroin, opium, or other specified opioids, that was inflicted by another person. The patient is in the acute phase of treatment for the poisoning.

Apply this code when documentation clearly indicates a patient presenting with symptoms of narcotic poisoning (e.g., respiratory depression, altered mental status) due to an assault. This includes situations where a narcotic was administered against the patient's will or in a malicious manner by another individual.

• Always confirm the specific narcotic involved to ensure it falls under "other narcotics" and not a more specific category.
• Verify the intent of the poisoning is explicitly documented as an "assault" by another party.
• Ensure the encounter is the initial treatment for this specific poisoning event.
