2026 ICD-10-CM Diagnosis Code F12.951 – Cannabis use, unspecified with psychotic disorder with hallucinations
What it is
This code identifies cannabis use, unspecified, when the patient also has a psychotic disorder with hallucinations. It indicates a documented relationship between cannabis use and psychotic symptoms, but the specific pattern of use is not further described.
Clinical signs
Clinical features include hallucinations plus other psychotic symptoms such as disturbed thinking, altered perception, or impaired reality testing. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record states cannabis use, unspecified, and also documents psychotic disorder with hallucinations. It may apply when the clinician links the psychosis to cannabis use or records both conditions together. Check documentation for the exact wording and causal relationship.
Do not use for
Do not use this code if hallucinations are documented without a psychotic disorder, or if the cannabis use type is specified elsewhere in the record. Do not assume causation without provider documentation.
Coding tip
Confirm that both cannabis use and psychotic disorder with hallucinations are documented before assigning F12.951.
