Cannabis use, unspecified with anxiety disorder

This code signifies a patient's problematic pattern of cannabis use that has not been specified as mild, moderate, or severe, and is concurrently experiencing an anxiety disorder. The cannabis use is characterized by clinically significant impairment or distress, and the anxiety disorder is a distinct, co-occurring mental health condition.

Apply this code when documentation indicates a patient has an unspecified cannabis use disorder and a co-occurring anxiety disorder, but the severity of the cannabis use is not specified (e.g., "cannabis use disorder with anxiety"). This code is appropriate when the provider has diagnosed both conditions, and the anxiety is not explicitly stated as substance-induced.

• Ensure documentation clearly links the anxiety disorder to the cannabis use, or at least indicates their co-occurrence.
• Do not use this code if the anxiety is explicitly documented as cannabis-induced; instead, refer to codes in the F12.18x or F12.28x series.
• If the severity of the cannabis use is specified (e.g., mild, moderate, severe), select a more specific code from the F12.18x or F12.28x series.
