ICD-10 Code F11.159 – Opioid abuse with opioid-induced psychotic disorder, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F11.159 – Opioid abuse with opioid-induced psychotic disorder, unspecified
What it is
Use this code for opioid abuse when the patient also has a psychotic disorder caused by opioid use, but the psychosis type is not further specified. It indicates a substance-related mental disorder linked to opioids.
Clinical signs
Clinical features vary; refer to documentation. Typical psychotic findings may include hallucinations, delusions, or disorganized thinking that are attributed to opioid use rather than a primary psychotic disorder.
When to use this code
Use F11.159 when the record clearly documents opioid abuse and an opioid-induced psychotic disorder, unspecified. Choose it when the provider links the psychotic symptoms to opioid use and does not document a more specific psychotic subtype. Check documentation if the substance relationship is unclear.
Do not use for
Do not use this code for opioid dependence, remission states, or psychosis unrelated to opioid use. Do not assign it when the chart identifies a different substance or a primary psychotic disorder.
Coding tip
Verify that both opioid abuse and substance-induced psychosis are documented together before assigning this code.
