Toxic effect of tobacco cigarettes, undetermined, init

This code signifies a harmful physiological response to tobacco cigarettes where the intent (e.g., accidental, intentional self-harm) is not yet determined. It indicates that the patient is experiencing adverse effects directly attributable to cigarette exposure.

Apply this code when a patient presents with symptoms of tobacco cigarette toxicity, such as acute nicotine poisoning or carbon monoxide poisoning from smoking, and the healthcare provider has not documented whether the exposure was accidental, intentional, or assault. It is appropriate for the initial visit for this specific toxic event.

• Ensure documentation clearly links the patient's symptoms to tobacco cigarette exposure.
• Only use the "A" (initial encounter) seventh character for the first time the patient is seen for this specific toxic event.
• If the intent of the exposure is later determined, a more specific T code (e.g., T65.211A for accidental) should be used for subsequent encounters.
