Poisoning by other narcotics, undetermined, subs encntr

This code signifies a patient presenting for follow-up care or treatment of complications arising from an overdose or adverse reaction to a narcotic substance other than heroin, opium, or synthetic/other specified narcotics. The intent of the poisoning (e.g., accidental, intentional self-harm, assault) could not be determined at the time of encounter.

Apply this code when documenting subsequent care for a patient previously diagnosed with poisoning by an unspecified narcotic, where the intent of the poisoning remains unknown. This includes encounters for ongoing management of organ damage, psychological sequelae, or withdrawal symptoms related to the initial poisoning event.

• Ensure the encounter is for follow-up care related to the initial poisoning, not the initial acute treatment.
• Confirm documentation explicitly states the narcotic involved is not heroin, opium, or a synthetic/other specified narcotic.
• Verify that the intent of the poisoning is clearly documented as "undetermined" or "unspecified."
