sire or urge to use the inhalant substance,” may be met).
In sustained remission: After full criteria for inhalant use disorder were previously
met, none of the criteria for inhalant 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 inhalant substance,” may be met).
Specify if:
In a controlled environment:  This additional specifier is used if the individual is in an
environment where access to inhalant substances is restricted. 
Coding based on current severity:  Note for ICD-10-CM codes: If an inhalant intoxication
or another inhalant-induced mental disorder is also present, do not use the codes below
for inhalant use disorder. Instead, the comorbid inhalant use disorder is indicated in the
4th character of the inhalant-induced disorder code (see the coding note for inhalant intox-
ication or a specific inhalant-induced mental di sorder). For example, if there is comorbid
inhalant-induced depressive disorder and i nhalant use disorder, only the inhalant-induced
depressive disorder code is given, with the 4th character indicating whether the comorbid
inhalant use disorder is mild, moderate, or severe: F18.14 for mild inhalant use disorder
with inhalant-induced depressive disorder or F 18.24 for a moderate or severe inhalant use
disorder with inhalant-induced depressive disorder.
Specify current severity:
305.90 (F18.10) Mild:  Presence of 2–3 symptoms.
304.60 (F18.20) Moderate: Presence of 4–5 symptoms.
304.60 (F18.20) Severe:  Presence of 6 or more symptoms.
