CM code depends on whether or not there is a co morbid substance use disorder present for
the same class of substance. If a mild substance use disorder is comorbid with the substance-
induced bipolar and related disorder, the 4th position character is “1,” and the clinician should
record “mild [substance] use disorder” before the substance-induced bipolar and related dis-
order (e.g., “mild cocaine use disorder with coca ine-induced bipolar and related disorder”). If a
moderate or severe substance use disorder is comorbid with the substance-induced bipolar
and related disorder, the 4th position character is “2,” and the clinician should record “moder-
ate [substance] use disorder” or “severe [subs tance] use disorder,” depending on the severity
of the comorbid substance use disorder. If there is no comorbid substance use disorder (e.g.,
after a one-time heavy use of the substance), then the 4th position character is “9,” and the
clinician should record only the substance-induced bipolar and related disorder.
