Unspecified psychosis not due to a substance or known physiological condition
Chapter 5:Mental, Behavioral and Neurodevelopmental disorders
ICD-10 F29 is a billable code used to indicate a diagnosis of unspecified psychosis not due to a substance or known physiological condition.
F29 refers to a category of psychotic disorders characterized by the presence of psychotic symptoms such as delusions, hallucinations, disorganized thinking, and impaired functioning, without a clear etiology linked to substance use or identifiable physiological conditions. This diagnosis is often used when the clinician cannot specify the type of psychosis, which may include elements from schizophrenia spectrum disorders or other psychotic disorders. Patients may exhibit significant distress and impairment in social, occupational, or other important areas of functioning. The diagnosis requires careful clinical assessment to rule out other causes, including substance-induced psychosis or medical conditions that could explain the symptoms. Treatment typically involves antipsychotic medications, psychotherapy, and supportive services, with the goal of managing symptoms and improving the patient's quality of life.
