F15.9Other stimulant use, unspecified

F15.9 is the ICD-10-CM diagnosis code for other stimulant use, unspecified. It belongs to category F15 (other stimulant 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 8 subcodes must be used instead.

Within F15, choose F15.9 (use, unspecified) only when documentation doesn't support a more specific option: abuse (F15.1) and dependence (F15.2).

To report this condition, pick the subcode that matches the documentation: F15.90 (uncomplicated), F15.91 (in remission), F15.92 (with intoxication), F15.93 (with withdrawal), F15.94 (with stimulant-induced mood disorder), F15.95 (with stimulant-induced psychotic disorder), F15.98 (with other stimulant-induced disorder) and F15.99 (with unspecified stimulant-induced disorder).

Don't report F15.9 together with the conditions in its Excludes1 note: other stimulant abuse (F15.1-) and other stimulant dependence (F15.2-).

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