ICD-10 Code F12.950 – Cannabis use, unspecified with psychotic disorder with delusions (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F12.950 – Cannabis use, unspecified with psychotic disorder with delusions
What it is
Use this code for cannabis use, unspecified when the patient also has a psychotic disorder with delusions. It identifies a cannabis-related condition where delusional thinking is documented.
Clinical signs
Look for documented delusions, such as fixed false beliefs, occurring with psychotic symptoms in the setting of cannabis use. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly links cannabis use, unspecified, with psychotic disorder and delusions. It fits when the clinician documents cannabis-related psychosis and does not specify another cannabis use category. If the note is unclear, check documentation.
Do not use for
Do not use this code if psychosis is not documented or if a different substance is identified as the cause. Do not use it when the chart specifies another cannabis use code.
Coding tip
Code the documented substance and psychotic feature exactly as stated; do not infer delusions from behavior alone.
