ICD-10-CM F23: Brief Psychotic Disorder Overview

This group represents acute onset psychotic syndromes characterized by delusions, hallucinations, disorganized speech, or grossly disorganized or catatonic behavior that are short in duration. These diagnoses target psychiatric/behavioral health conditions affecting thought content and perception. Accurate coding supports clinical continuity and proper reimbursement for mental health services.

When to Use

Use a code from this group when a patient presents with an acute psychotic episode of short duration that meets diagnostic criteria for brief psychotic disorder or other transient psychoses. Select the specific code that reflects the documented symptom profile, presence or absence of stressors, and the temporal pattern of onset and resolution.

Typical Clinical Scenarios

A previously healthy 25-year-old presents to the emergency department after family report abrupt onset of disorganized behavior, visual hallucinations, and paranoid delusions lasting 3 days following an acute severe stressful event (bereavement). The patient has intact sensorium, no prior psychiatric history, and medical workup is unrevealing; symptoms are acute, nonbizarre, and expected to remit within a month, so a brief psychotic disorder diagnosis is assigned to capture the acute, time-limited psychotic episode. Typical codes: F23
A 45-year-old with no history of psychotic illness is admitted to inpatient psychiatry for sudden onset of perplexity, pressured speech, and persecutory delusions that began within 2 weeks and markedly impair occupational functioning; toxicology, metabolic, and neurologic evaluations are negative. Because the psychosis is of recent onset, not attributable to a medical condition or substance, and is suspected to resolve in a short period, a code from this group is used to document an acute nonmood psychotic disorder. Typical codes: F23
A 30-year-old postpartum woman develops brief florid psychotic symptoms including auditory hallucinations, disorganized behavior, and transient delusional beliefs within days of delivery, prompting urgent psychiatric assessment and short-term hospitalization. With onset closely linked to the peripartum period, rapid evaluation excludes delirium and substance causes, and the clinician assigns a brief psychotic disorder diagnosis to reflect the acute, time-limited psychosis requiring immediate but typically short-duration treatment. Typical codes: F23
