Substance/Medication-Induced Psychotic Disorder 111
Coding note: The ICD-9-CM and ICD-10-CM codes for the [specific substance/medica-
tion]-induced psychotic disorders are indicated in the table below. Note that the ICD-10-
CM code depends on whether or not there is a comorbid substance use disorder present
for the same class of substance. If a mild substance use disorder is comorbid with the sub-
stance-induced psychotic disorder, the 4th position character is “1,” and the clinician should
record “mild [substance] use disorder” before the substance-induced psychotic disorder
(e.g., “mild cocaine use diso rder with cocaine-induced ps ychotic disorder”). If a m oderate or
severe substance use disorder is comorbid with the substance-induced psychotic disor-
der, the 4th position character is “2,” and the clinician should record “moderate [substance]
use disorder” or “severe [substance] use disorder,” depending on the severity of the co-
morbid 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 cli-
nician should record only the substance-induced psychotic disorder.

stance and the symptoms develop during intoxication.
With onset during withdrawal:  If the criteria are met for withdrawal from the sub-
stance and the symptoms develop during, or shortly after, withdrawal.
