Schizophrenia, schizotypal, delusional, and other non-mood psychotic disorders (F20-F29)

The ICD-10 codes from F20 to F29 cover a range of serious psychiatric conditions known as schizophrenia, schizotypal, delusional, and other non-mood psychotic disorders. These codes specifically classify various forms of schizophrenia and related psychotic disorders, helping healthcare professionals accurately identify and treat these complex mental health conditions.

This code range includes detailed classifications for different types of schizophrenia such as paranoid (F20.0), disorganized (F20.1), and catatonic schizophrenia (F20.2), including their acute or chronic states and remission phases. The codes also cover schizotypal disorder (F21), which relates to personality and prodromal symptoms, and delusional disorders (F22) characterized by fixed false beliefs, sometimes including complex syndromes like erotomanic or persecutory delusions. Brief psychotic episodes (F23) and shared psychotic disorders, also known as folie à trois (F24), are included. Schizoaffective disorders (F25) combine mood and psychotic symptoms, with separate codes for bipolar and depressive types. Lastly, unspecified psychotic disorders (F28 and F29) cover cases not due to substances or physiological causes. These codes support precise diagnosis and treatment planning by distinguishing subtle differences among psychotic disorders and their progressions.
