About F17.20

F17.20 is the ICD-10-CM diagnosis code for nicotine dependence, unspecified. 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, choose F17.20 (unspecified) only when documentation doesn't support a more specific option: cigarettes (F17.21), chewing tobacco (F17.22) and other tobacco product (F17.29).

To report this condition, pick the subcode that matches the documentation: F17.200 (uncomplicated), F17.201 (in remission), F17.203 (withdrawal), F17.208 (with other nicotine-induced disorders) and F17.209 (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.
