Toxic effect of oth tobacco and nicotine, undetermined, init

This code signifies a harmful physiological reaction resulting from exposure to tobacco products or nicotine, excluding those specified elsewhere, where the intent of the exposure (e.g., accidental, intentional self-harm, assault) cannot be determined. The patient is presenting for the initial treatment of this adverse effect.

Apply this code when a patient experiences an acute toxic effect from an unspecified tobacco or nicotine product, and the medical record does not clarify whether the exposure was accidental, intentional, or due to assault. This is appropriate for the first encounter for this specific toxic event.

• Ensure the documentation explicitly states "undetermined intent" for the tobacco/nicotine exposure.
• Only use the "A" seventh character for the initial encounter for this specific toxic event.
• Do not use this code if the type of tobacco/nicotine product is specified (e.g., smokeless tobacco, e-liquids) or if the intent is clearly documented.
