3. A great deal of time is spent in activities necessary to obtain the hallucinogen, use the hallucinogen, or recover from its effects.
4. Craving, or a strong desire or urge to use the hallucinogen.
5. Recurrent hallucinogen use resulting in a failure to fulfill major role obligations at work, school, or home (e.g., repeated absences from work or poor work perfor- mance related to hallucinogen use; hallucinogen-related absences. suspensions, or expulsions from school; neglect of children or household).
6. Continued hallucinogen use despite having persistent or recurrent social or inter- personal problems caused or exacerbated by the effects of the hallucinogen (e.g., arguments with a spouse about consequences of intoxication; physical tights).
7. Important social, occupational, or recreational activities are given up or reduced be- cause of hallucinogen use.
8. Recurrent hallucinogen use in situations in which it is physically hazardous (e.g., driving an automobile or operating a machine when impaired by the hallucinogen).
9. Hallucinogen use is continued despite knowledge of having a persistent or recur- rent physical or psychological problem that is likely to have been caused or exac- erbated by the hallucinogen.
10. Tolerance, as defined by either of the following: a. A need for markedly increased amounts of the hallucinogen to achieve intoxi- cation or desired effect.
b. A markedly diminished effect with continued use of the same amount of the hal- lucinogen.
Note: Withdrawal symptoms and signs are not established for hallucinogens, and so this criterion does not apply.
Specify the particular hallucinogen.
Specify ii:
In early remission: After full criteria for other hallucinogen use disorder were previ- ously met, none of the criteria for other hallucinogen use disorder have been met for at least 3 months but for less than 12 months (with the exception that Criterion A4, “Craving, or a strong desire or urge to use the hallucinogen,” may be met).
In sustained remission: After full criteria for other hallucinogen use disorder were previously met, none of the criteria for other hallucinogen use disorder have been met at any time during a period of 12 months or longer (with the exception that Criterion A4, “Craving. or a strong desire or urge to use the hallucinogen," may be met).
Specify if:
In a controlled environment: This additional specifier is used if the individual is in an environment where access to hallucinogens is restricted.
Coding based on current severity: Note for ICD-10-CM codes: It a hallucinogen intoxication or another hallucinogen-induced mental disorder is also present, do not use the codes below for hallucinogen use disorder. Instead, the comorbid hallucinogen use disorder is indicated in the 4th character of the hallucinogen-induced disorder code (see the coding note for halluci- nogen intoxication or specific hallucinogen-induced mental disorder). For example, if there is comorbid hallucinogen-induced psychotic disorder and hallucinogen use disorder, only the hallucinogen-induced psychotic disorder code is given, with the 4th character indicating wheth- er the comorbid hallucinogen use disorder is mild, moderate, or severe: F16.159 for mild hal- lucinogen use disorder with hallucinogen-induced psychotic disorder or F16.259 for a moderate or severe hallucinogen use disorder with hallucinogen-induced psychotic disorder.
Specify current severity: 305.30 (F16.10) Mild: Presence of 2—3 symptoms.
304.50 (F16.20) Moderate: Presence 014—5 symptoms.
304.50 (F16.20) Severe: Presence of 6 or more symptoms.
