Brief psychotic disorder

This code represents a sudden onset of psychotic symptoms, such as delusions, hallucinations, disorganized speech, or grossly disorganized or catatonic behavior, lasting more than one day but less than one month. The individual typically returns to full premorbid functioning after the episode.

Assign this code when documentation indicates an acute, time-limited psychotic episode without a clear underlying mood disorder or substance use. This diagnosis is often made after ruling out other causes of psychosis.

• Carefully review documentation to ensure the duration of symptoms is less than one month.
• Differentiate from mood disorders with psychotic features; the "Excludes2" note is crucial here.
• Ensure there is no evidence of a substance-induced psychosis or another medical condition causing the symptoms.
