Cannabis abuse with psychotic disorder with delusions

This code signifies a pattern of problematic cannabis use leading to clinically significant impairment or distress, specifically when accompanied by a psychotic disorder characterized by delusions. The delusions are directly attributable to the effects of cannabis use.

Apply this code when a patient presents with symptoms of cannabis abuse and a co-occurring psychotic disorder where delusions are a prominent feature and are judged to be substance-induced. Documentation should clearly link the onset or exacerbation of delusions to cannabis use and indicate a problematic pattern of use.

• Ensure documentation explicitly states "delusions" as the primary psychotic symptom, not just general psychosis.
• Distinguish from primary psychotic disorders where cannabis use is incidental or a comorbidity, rather than causative.
• Consider sequencing with codes for other substance use disorders if present, following official ICD-10-CM guidelines.
