ICD-10 Code F19.95 – Other psychoactive substance use, unspecified with psychoactive substance-induced psychotic disorder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F19.95 – Other psychoactive substance use, unspecified with psychoactive substance-induced psychotic disorder
What it is
This code identifies psychosis caused by an unspecified psychoactive substance. Use it when the record links hallucinations, delusions, or similar symptoms to substance use, but the exact substance is not named.
Clinical signs
Clinical features vary; refer to documentation. Commonly documented findings include hallucinations, delusions, disorganized thinking, or marked behavioral disturbance occurring in the setting of substance use.
When to use this code
Use this code when the clinician documents a psychoactive substance-induced psychotic disorder and does not specify the substance. It may apply when the note states “other psychoactive substance” or leaves the agent unidentified. Check documentation for the causal relationship and whether the psychotic disorder is current.
Do not use for
Do not use this code for psychosis unrelated to substance use, or when a more specific substance is documented. If the record only shows intoxication, withdrawal, or dependence without psychosis, choose the appropriate different code.
Coding tip
Assign the most specific substance-related code available; if the substance is not named, document that the agent is unspecified.
