F12.1Cannabis abuse

F12.1 is the ICD-10-CM diagnosis code for cannabis abuse. It belongs to category F12 (cannabis related disorders), 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 7 subcodes must be used instead.

Within F12 (cannabis related disorders), F12.1 is specifically for cannabis abuse. Related codes cover dependence (F12.2) and use, unspecified (F12.9).

To report this condition, pick the subcode that matches the documentation: F12.10 (uncomplicated), F12.11 (in remission), F12.12 (with intoxication), F12.13 (with withdrawal), F12.15 (with psychotic disorder), F12.18 (with other cannabis-induced disorder) and F12.19 (with unspecified cannabis-induced disorder).

Don't report F12.1 together with the conditions in its Excludes1 note: cannabis dependence (F12.2-) and cannabis use, unspecified (F12.9-).

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