Quick reference
- When to use
- Use F23 when the client presents with psychotic symptoms consistent with Brief Psychotic Disorder. Ensure adequate duration criteria are met. Rule out substance-induced and medical causes before assigning a primary psychotic disorder code.
- Duration
- Schizophrenia: 6+ months continuous signs (1+ month active). Brief Psychotic Disorder: 1 day to 1 month. Schizoaffective: longitudinal course assessment needed. Document course specifiers.
- Session codes
- Pair with CPT 90834/90837 for therapy. Medication management: 99214/99215. 90853 for group skills training. 90785 for interactive complexity. Case management and ACT services may be warranted.
- Key indicators
- Delusions • Hallucinations • Disorganized speech • Grossly disorganized or catatonic behavior • Negative symptoms (flat affect, avolition) • Functional decline • Duration requirements vary by diagnosis
What F23 represents
Brief psychotic disorder involves sudden onset of at least one psychotic symptom (delusions, hallucinations, disorganized speech, or grossly disorganized/catatonic behavior) lasting between 1 day and 1 month, with eventual full return to premorbid functioning.
Key diagnostic criteria
- 1+ of: delusions, hallucinations, disorganized speech, grossly disorganized/catatonic behavior
- Duration: 1 day to 1 month
- Full return to premorbid functioning
- Not better explained by MDD/bipolar with psychotic features, schizophrenia, or substance effects
Specify: with/without marked stressor, with peripartum onset
Documentation essentials

Treatment planning
Short-term antipsychotic medication. Supportive therapy. Crisis management. Monitor for progression to other psychotic disorders.
