Toxic effect of tobacco and nicotine, self-harm, subs

This code signifies a toxic reaction resulting from the deliberate self-administration of tobacco or nicotine products, excluding those specifically categorized elsewhere (e.g., pesticides, solvents). It indicates that the patient is receiving follow-up care for this intentional poisoning event, rather than the initial treatment. The toxicity could manifest as various symptoms, from nausea and vomiting to cardiovascular effects, depending on the substance and dose.

Apply this code when documenting subsequent encounters for a patient who intentionally poisoned themselves with a tobacco or nicotine product not otherwise specified. This includes follow-up appointments, medication adjustments, or ongoing monitoring after the initial acute treatment. It is crucial to use this code for any encounter after the initial hospitalization or emergency department visit for the self-harm incident.

• Ensure the documentation clearly states "intentional self-harm" and specifies a tobacco or nicotine product.
• Verify that the encounter is for follow-up care, not the initial treatment of the acute poisoning.
• Always sequence this code after any codes for the specific manifestations of the toxicity.
