ICD-10 Code F06.0 – Psychotic disorder with hallucinations due to known physiological condition (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F06.0 – Psychotic disorder with hallucinations due to known physiological condition
What it is
This code identifies a psychotic disorder caused by a known physiological condition, with hallucinations as a key feature. You use it when the hallucinations are attributable to an underlying medical cause rather than a primary psychiatric disorder.
Clinical signs
Clinical features vary; refer to documentation. Hallucinations may be auditory, visual, or other sensory types, and the record should support a physiological cause linked to the psychotic symptoms.
When to use this code
Use this code when the provider documents hallucinations due to a known physiological condition, such as a neurologic or other medical disorder. It fits cases where the psychotic symptoms are secondary to the underlying condition and not better classified elsewhere. Check documentation for the stated cause and symptom relationship.
Do not use for
Do not use this code for primary psychotic disorders without a physiological cause. Also avoid it when the chart does not clearly link hallucinations to a known medical condition.
Coding tip
Code the underlying physiological condition first when documented, and verify that hallucinations are explicitly attributed to it.
