Cannabis use, unsp with psychotic disorder with delusions

This code signifies a diagnosis of cannabis use disorder where the specific pattern of use (e.g., abuse, dependence) is not documented, and the patient is experiencing a psychotic disorder characterized by delusions. The psychotic symptoms are directly attributable to the cannabis use.

Apply this code when documentation clearly indicates a patient's cannabis use is unspecified, and they present with a psychotic disorder featuring delusions that are determined to be substance-induced. This is appropriate when the clinician explicitly links the delusions to the cannabis use and does not specify the severity or pattern of cannabis use.

• Ensure documentation explicitly states "unspecified" cannabis use and the presence of delusions as part of the psychotic disorder.
• Do not use if the psychotic disorder is pre-existing or not directly linked to cannabis use; consider other F20-F29 codes.
• Sequence this code first if the cannabis-induced psychotic disorder is the primary reason for the encounter.
