Poisoning by other synthetic narcotics, assault, init

This code signifies an intentional act of harm where a patient has been poisoned by a synthetic narcotic other than fentanyl or tramadol. The poisoning is a result of an assault, meaning another party deliberately administered the substance with malicious intent. The "initial encounter" indicates this is the first time the patient is receiving care for this specific poisoning event.

Apply this code when documentation clearly states a patient has been poisoned by a synthetic narcotic (e.g., meperidine, methadone, propoxyphene, etc., but not fentanyl or tramadol) due to an assault. This would be used for the initial hospital visit, emergency department encounter, or first physician office visit related to the poisoning.

• Always sequence this code first if it is the primary reason for the encounter.
• Ensure the documentation specifies "assault" and identifies the substance as a "synthetic narcotic" (excluding fentanyl/tramadol).
• Do not use for accidental poisonings, self-harm, or adverse effects of properly administered drugs.
