About F11.98

F11.98 is the ICD-10-CM diagnosis code for opioid use, unspecified with other specified opioid-induced disorder. It belongs to category F11 (opioid 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 F11.9, choose F11.98 (with other specified opioid-induced disorder) only when documentation doesn't support a more specific option: uncomplicated (F11.90), in remission (F11.91), with intoxication (F11.92), with withdrawal (F11.93), with opioid-induced mood disorder (F11.94), with opioid-induced psychotic disorder (F11.95) and with unspecified opioid-induced disorder (F11.99).

To report this condition, pick the subcode that matches the documentation: F11.981 (dysfunction), F11.982 (disorder) and F11.988 (disorder).

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