F10.9Alcohol use, unspecified

F10.9 is the ICD-10-CM diagnosis code for alcohol use, unspecified. It belongs to category F10 (alcohol 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 10 subcodes must be used instead.

Within F10, choose F10.9 (use, unspecified) only when documentation doesn't support a more specific option: abuse (F10.1) and dependence (F10.2).

To report this condition, pick the subcode that matches the documentation: F10.90 (uncomplicated), F10.91 (in remission), F10.92 (with intoxication), F10.93 (with withdrawal), F10.94 (with alcohol-induced mood disorder), F10.95 (with alcohol-induced psychotic disorder), F10.96 (with alcohol-induced persisting amnestic disorder), F10.97 (with alcohol-induced persisting dementia) and 2 more.

Don't report F10.9 together with the conditions in its Excludes1 note: alcohol abuse (F10.1-) and alcohol dependence (F10.2-).

Use an additional code for blood alcohol level, if applicable (Y90.-).

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