Patient presents with symptoms suggestive of unspecified psychosis.  The clinical presentation includes [specific symptoms observed, e.g., disorganized thought process, perceptual disturbances such as hallucinations or illusions, unusual or bizarre behavior, impaired reality testing].  Differential diagnoses considered include [list differential diagnoses, e.g., schizophrenia, schizophreniform disorder, brief psychotic disorder, schizoaffective disorder, substance-induced psychotic disorder, psychotic disorder due to another medical condition, other specified schizophrenia spectrum and other psychotic disorders].  However, the patient does not meet the full criteria for any of these specific diagnoses based on the duration, symptom profile, and current clinical picture.  Assessment includes a thorough mental status examination, review of medical history including substance use history, and consideration of any relevant psychosocial stressors.  Current symptoms cause clinically significant distress or impairment in social, occupational, or other important areas of functioning.  The patient's presentation warrants a diagnosis of unspecified psychosis (ICD-10 code F29) as the most accurate reflection of the current clinical picture.  Treatment plan includes [specific treatment recommendations, e.g., initiation of antipsychotic medication, referral for psychotherapy,  patient education regarding psychosis, family support and education].  Further assessment and diagnostic clarification will be pursued in subsequent visits to determine if the clinical picture evolves to meet the criteria for a more specific psychotic disorder diagnosis.  Prognosis and potential treatment response will be continually evaluated.  Patient understanding of the diagnosis and treatment plan was assessed and documented.
