Toxic effect of tobacco cigarettes, accidental, init

This diagnosis code signifies an adverse health effect resulting from unintentional exposure to the toxic substances found in tobacco cigarettes. This typically involves accidental ingestion, inhalation, or dermal contact with cigarette components, leading to a harmful physiological response. It specifically excludes intentional self-harm or assault.

Apply this code for patients presenting with symptoms of poisoning or toxicity due to accidental exposure to tobacco cigarettes, such as a toddler ingesting cigarette butts or a child accidentally inhaling smoke from a discarded cigarette. This code is appropriate for the initial visit where the patient is receiving active treatment for the toxic effect.

• Ensure documentation clearly states the exposure was accidental and not intentional.
• Confirm this is the patient's first encounter for this specific toxic effect. Subsequent encounters would use different seventh characters.
• Always code the specific symptoms or manifestations of the toxicity in addition to this external cause code.
