F16.2Hallucinogen dependence

F16.2 is the ICD-10-CM diagnosis code for hallucinogen dependence. It belongs to category F16 (hallucinogen 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 F16 (hallucinogen related disorders), F16.2 is specifically for hallucinogen dependence. Related codes cover abuse (F16.1) and use, unspecified (F16.9).

To report this condition, pick the subcode that matches the documentation: F16.20 (uncomplicated), F16.21 (in remission), F16.22 (with intoxication), F16.24 (with hallucinogen-induced mood disorder), F16.25 (with hallucinogen-induced psychotic disorder), F16.28 (with other hallucinogen-induced disorder) and F16.29 (with unspecified hallucinogen-induced disorder).

Don't report F16.2 together with the conditions in its Excludes1 note: hallucinogen abuse (F16.1-) and hallucinogen use, unspecified (F16.9-).

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