Nicotine dependence, cigarettes, w oth disorders

This code signifies a patient's physiological or psychological dependence on nicotine, specifically from cigarette use, accompanied by additional health problems directly attributable to nicotine. These "other nicotine-induced disorders" can include conditions like nicotine withdrawal, nicotine-induced sleep disorders, or other specified nicotine-induced mental or behavioral disorders.

Apply this code when documentation clearly indicates a patient's addiction to cigarettes and also specifies a co-occurring nicotine-induced condition. This is appropriate for patients presenting with withdrawal symptoms, mood disturbances, or other physical or mental health issues directly linked to their cigarette dependence. Supporting documentation should detail both the dependence and the specific nicotine-induced disorder.

• Ensure the documentation explicitly states "cigarettes" as the source of nicotine dependence, not other tobacco products.
• Do not use this code if the patient has nicotine dependence without any other specified nicotine-induced disorder; a different F17.21x code would be more appropriate.
• Always sequence this code as a primary diagnosis when the nicotine dependence and its associated disorder are the primary reason for the encounter, or as a secondary diagnosis when it impacts the patient's overall care.
