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

This code signifies a long-term consequence or complication arising from a previous act of intentional self-harm involving other tobacco products or nicotine. It indicates that the patient is experiencing a residual health problem directly attributable to a past self-inflicted toxic exposure to these substances. This is not for the acute poisoning event itself, but rather the lasting effects.

Apply this code when documenting conditions such as chronic respiratory issues, cardiovascular damage, or neurological deficits that are determined to be sequelae of a prior intentional overdose or poisoning with tobacco or nicotine. This would be used in follow-up encounters after the initial acute treatment for the self-harm event has concluded.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic bronchitis).
• Ensure documentation clearly links the current condition to a past intentional self-harm event involving tobacco or nicotine.
• Do not use this code for accidental exposures, therapeutic misadventures, or acute poisoning events.
