F18.98Inhalant use, unspecified with other inhalant-induced disorders

F18.98 is the ICD-10-CM diagnosis code for Inhalant use, unspecified with other inhalant-induced disorders. It belongs to category F18 (Inhalant 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 2 subcodes must be used instead.

Within F18.9, choose F18.98 (with other inhalant-induced disorders) only when documentation doesn't support a more specific option: uncomplicated (F18.90), in remission (F18.91), with intoxication (F18.92), with inhalant-induced mood disorder (F18.94), with inhalant-induced psychotic disorder (F18.95), with inhalant-induced persisting dementia (F18.97) and with unspecified inhalant-induced disorder (F18.99).

To report this condition, pick the subcode that matches the documentation: F18.980 (disorder) and F18.988 (disorder).

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