F13.9Sedative, hypnotic or anxiolytic-related use, unspecified

F13.9 is the ICD-10-CM diagnosis code for sedative, hypnotic or anxiolytic-related use, unspecified. It belongs to category F13 (sedative, hypnotic, or anxiolytic 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 F13, choose F13.9 (use, unspecified) only when documentation doesn't support a more specific option: abuse (F13.1) and dependence (F13.2).

To report this condition, pick the subcode that matches the documentation: F13.90 (uncomplicated), F13.91 (remission), F13.92 (intoxication), F13.93 (withdrawal), F13.94 (disorder), F13.95 (disorder), F13.96 (disorder), F13.97 (dementia) and 2 more.

Don't report F13.9 together with the conditions in its Excludes1 note: sedative, hypnotic or anxiolytic-related abuse (F13.1-) and sedative, hypnotic or anxiolytic-related dependence (F13.2-).

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