Poisoning by other narcotics, undetermined, init encntr

This code signifies a patient presenting with adverse effects from an unspecified narcotic substance, where the intent (e.g., accidental, intentional self-harm, assault) cannot be determined at the time of encounter. The patient is experiencing the initial phase of treatment for this poisoning.

Apply this code when a patient is admitted or seen in the emergency department due to poisoning by a narcotic that is not specifically identified as opium, heroin, or another specific opioid, and the provider cannot ascertain whether the poisoning was accidental, intentional, or due to assault. This is appropriate for the first time the patient is receiving care for this particular poisoning event.

• Always sequence this code first, followed by codes for any associated manifestations of the poisoning.
• Do not use this code if the intent of the poisoning is known (e.g., accidental, intentional self-harm); instead, select the appropriate intent code.
• The "A" seventh character indicates an initial encounter, meaning the patient is actively receiving treatment for the condition.
