Other psychotic disorder not due to a substance or known physiological condition
Chapter 5:Mental, Behavioral and Neurodevelopmental disorders
ICD-10 F28 is a billable code used to indicate a diagnosis of other psychotic disorder not due to a substance or known physiological condition.
F28 encompasses a range of psychotic disorders that do not fall under the categories of schizophrenia spectrum disorders or are not attributable to substance use or identifiable physiological conditions. Patients with F28 may experience delusions, hallucinations, disorganized thinking, and other symptoms that significantly impair their social and occupational functioning. Unlike schizophrenia, which has specific diagnostic criteria, F28 serves as a catch-all for atypical presentations of psychosis. The etiology of these disorders can be multifactorial, including genetic, environmental, and psychosocial factors. Treatment typically involves antipsychotic medications, psychotherapy, and supportive interventions aimed at improving the patient's quality of life. Clinicians must conduct thorough assessments to differentiate F28 from other psychotic disorders, ensuring accurate diagnosis and appropriate management.
Comprehensive psychiatric evaluation, including history of present illness, mental status examination, and treatment plan.
Patients presenting with acute psychosis without clear etiology, or those with chronic symptoms that do not fit other diagnoses.
Documenting the absence of substance use and physiological conditions is crucial for accurate coding.
Neurological examination findings, imaging results, and differential diagnosis considerations.
Patients with psychotic symptoms that may have a neurological basis but do not meet criteria for known conditions.
Collaboration with psychiatry may be necessary to rule out other causes of psychosis.
Used for initial assessment of patients suspected of having F28.
Detailed history, mental status exam, and treatment recommendations.
Psychiatrists should ensure comprehensive documentation to support the diagnosis.
Key symptoms include delusions, hallucinations, disorganized thinking, and significant impairment in social or occupational functioning. These symptoms must not be attributable to substance use or a known medical condition.
