Toxic effect of tobacco and nicotine, accidental, subs

This code signifies an adverse health effect resulting from unintentional exposure to tobacco or nicotine products other than pesticides, such as ingestion of e-liquid or nicotine patches. The patient is in the healing phase following the initial acute poisoning, requiring ongoing care or follow-up.

Apply this code for patients presenting for follow-up appointments, medication adjustments, or continued monitoring after an accidental tobacco or nicotine poisoning. This includes situations where the patient is recovering from the initial toxic effects and receiving subsequent treatment.

• Ensure the encounter is for follow-up care and not the initial acute treatment.
• Verify the exposure was accidental and not intentional self-harm or assault.
• Confirm the substance involved is tobacco or nicotine, excluding pesticides.
