ICD-10 Code F19.151 – Other Psychoactive Substance Abuse with Psychoactive Substance-Induced Psychotic Disorder with Hallucinations (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F19.151 – Other psychoactive substance abuse with psychoactive substance-induced psychotic disorder with hallucinations
What it is
This code identifies abuse of another psychoactive substance with a substance-induced psychotic disorder in which hallucinations are present. Use it when the psychosis is documented as caused by the substance and not by a primary mental disorder.
Clinical signs
Typical findings include hallucinations, impaired reality testing, and other psychotic symptoms that arise during or after substance use. Clinical features vary; refer to documentation for the specific substance, timing, and whether symptoms are attributed to intoxication or withdrawal.
When to use this code
Use this code when the record clearly links hallucinations and psychosis to abuse of a psychoactive substance other than alcohol, opioids, or cannabis, and the provider documents substance-induced psychosis. Apply it when the chart supports abuse rather than dependence or unspecified use. Check documentation if the substance type or causal relationship is unclear.
Do not use for
Do not use this code for primary psychotic disorders, hallucinations without a documented substance cause, or substance use that is not documented as abuse. If the condition is due to another drug class or a different substance-use pattern, check documentation.
Coding tip
Confirm both the substance category and the provider’s linkage between the substance and hallucinations before assigning F19.151.
