ICD-10 Code F19.150 – Other psychoactive substance abuse with psychoactive substance-induced psychotic disorder with delusions (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F19.150 – Other psychoactive substance abuse with psychoactive substance-induced psychotic disorder with delusions
What it is
This code identifies abuse of another psychoactive substance with a substance-induced psychotic disorder marked by delusions. Use it when the psychosis is directly linked to the substance and the record supports both abuse and delusional symptoms.
Clinical signs
Typical findings include fixed false beliefs, impaired reality testing, and behavior influenced by those beliefs. Clinical features vary; refer to documentation for whether the psychosis is attributed to the substance rather than a primary psychotic disorder.
When to use this code
Use this code when the provider documents psychoactive substance abuse and a psychotic disorder with delusions caused by that substance. It is appropriate when the chart clearly ties the delusions to substance use and does not describe a separate primary psychotic condition.
Apply it in encounters where the substance is identified as the cause of the psychotic episode, even if the specific substance is not named in the code title. Check documentation for the exact substance, pattern of use, and whether abuse is the documented diagnosis.
Do not use for
Do not use this code for psychosis without delusions, for intoxication alone, or for a primary psychotic disorder unrelated to substance use. Check documentation if the record does not clearly support abuse.
Coding tip
Confirm that both substance abuse and substance-induced delusions are documented before assigning F19.150.
