ICD-10 Code F12.980 – Cannabis use, unspecified with anxiety disorder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F12.980 – Cannabis use, unspecified with anxiety disorder
What it is
This code identifies cannabis use, unspecified, when the patient also has an anxiety disorder linked to or occurring with that use. It tells you the record supports both cannabis involvement and anxiety, but not a more specific cannabis-related diagnosis.
Clinical signs
Clinical features vary; refer to documentation. You may see anxiety, excessive worry, panic-like symptoms, restlessness, or avoidance behaviors documented alongside cannabis use.
When to use this code
Use this code when the provider documents cannabis use, but does not specify abuse, dependence, or another more specific cannabis-related condition, and also documents an anxiety disorder. The anxiety must be part of the recorded clinical picture, not assumed from symptoms alone. Check documentation for the exact wording and relationship.
Do not use for
Do not use this code if the chart supports a more specific cannabis-related disorder, such as abuse or dependence. Do not assign it for anxiety alone, or when the anxiety diagnosis is not documented with cannabis use.
Coding tip
Match the code to the provider’s exact substance-use wording and confirm that anxiety is documented as a separate supported diagnosis.
