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

This code signifies a patient presenting with adverse health effects resulting from the deliberate self-administration of tobacco or nicotine products, excluding those specified elsewhere (e.g., cigarettes, cigars). This could involve ingesting or otherwise misusing nicotine liquids, patches, or other non-standard tobacco forms with the intent to cause harm. The "initial encounter" designation indicates the patient is receiving active treatment for the toxic effect.

Use this code when a patient is admitted or seen for emergency treatment due to a suicide attempt or intentional self-poisoning involving products like nicotine e-liquids, chewing tobacco, or other non-specified tobacco/nicotine substances. This applies to the first time the patient is seen for this specific episode of care.

• Always sequence this code first as the primary diagnosis when it represents the reason for the encounter.
• Requires an additional code for the specific manifestation of the toxic effect (e.g., nausea, vomiting, cardiac arrhythmias).
• Distinguish from accidental poisoning (T65.291-) or assault (T65.294-).
