Coding note: The |CD-9-CM and ICD-10-CM codes for the [specific substance] in- toxication delirium are indicated in the table below. Note that the lCD-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 substance intoxication delirium, the 4th position character is “1," and the clinician should record “mild [substance] use disorder‘ before the substance intoxication de- lirium (e.g., “mild cocaine use disorder with cocaine intoxication delirium"). If a mod- erate or severe substance use disorder is comorbid with the substance intoxication delirium, the 4th position character is “2,” and the clinician should record “moderate [substance] use disordei” or “severe [substance] 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 posi- tion character is “9," and the clinician should record only the substance intoxication delirium.

Substance withdrawal delirium: This diagnosis should be made instead of sub- stance withdrawal when the symptoms in Criteria A and C predominate in the clinical picture and when they are sufficiently severe to warrant clinical attention.
