About F17.21

F17.21 is the ICD-10-CM diagnosis code for nicotine dependence, cigarettes. It belongs to category F17 (nicotine dependence), block F10-F19 (mental and behavioral disorders due to psychoactive substance use) and chapter 5 (mental, Behavioral and Neurodevelopmental disorders). It is a header code, so it can't be reported by itself; one of its 5 subcodes must be used instead.

Within F17.2 (nicotine dependence), F17.21 is specifically for nicotine dependence, cigarettes. Related codes cover unspecified (F17.20), chewing tobacco (F17.22) and other tobacco product (F17.29).

To report this condition, pick the subcode that matches the documentation: F17.210 (uncomplicated), F17.211 (in remission), F17.213 (with withdrawal), F17.218 (with other nicotine-induced disorders) and F17.219 (with unspecified nicotine-induced disorders).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
