F16.18Hallucinogen abuse with other hallucinogen-induced disorder

F16.18 is the ICD-10-CM diagnosis code for hallucinogen abuse with other hallucinogen-induced disorder. 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 F16.1, choose F16.18 (with other hallucinogen-induced disorder) only when documentation doesn't support a more specific option: uncomplicated (F16.10), in remission (F16.11), with intoxication (F16.12), with hallucinogen-induced mood disorder (F16.14), with hallucinogen-induced psychotic disorder (F16.15) and with unspecified hallucinogen-induced disorder (F16.19).

To report this condition, pick the subcode that matches the documentation: F16.180 (disorder), F16.183 ((flashbacks)) and F16.188 (disorder).

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