2026 ICD-10-CM Diagnosis Code F19.951 – Other psychoactive substance use, unspecified with psychoactive substance-induced psychotic disorder with hallucinations
What it is
This code identifies psychosis with hallucinations caused by an unspecified psychoactive substance. Use it when the record links substance use to the hallucinations and psychotic symptoms, but the exact substance is not named.
Clinical signs
Typical findings include hallucinations, delusions, disorganized thinking, or abnormal behavior occurring in the setting of substance use. Clinical features vary; refer to documentation.
When to use this code
Use this code when the clinician documents psychoactive substance use and a substance-induced psychotic disorder with hallucinations, but does not identify the substance. It can support coding from emergency, inpatient, or consultation notes when the relationship is clearly stated. Check documentation for the specific substance if available.
Do not use for
Do not use this code for primary psychotic disorders, such as schizophrenia, when substance causation is not documented. Do not use it if the record names a specific psychoactive substance and a more precise code is available.
Coding tip
Confirm that both the substance use and hallucinations are documented as substance-induced before assigning F19.951.
