About F16.22

F16.22 is the ICD-10-CM diagnosis code for hallucinogen dependence with intoxication. 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 3 subcodes must be used instead.

Within F16.2 (hallucinogen dependence), F16.22 is specifically for hallucinogen dependence with intoxication. Related codes cover uncomplicated (F16.20), in remission (F16.21), with hallucinogen-induced mood disorder (F16.24), with hallucinogen-induced psychotic disorder (F16.25), with other hallucinogen-induced disorder (F16.28) and with unspecified hallucinogen-induced disorder (F16.29).

To report this condition, pick the subcode that matches the documentation: F16.220 (uncomplicated), F16.221 (with delirium) and F16.229 (unspecified).

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