Differences – Schizophrenia

ICD-11 coding for courses:

• 6A20.0: Schizophrenia, first episode
• 6A20.1: Schizophrenia, multiple episodes
• 6A20.2: Schizophrenia, continuous
• 6A20.Y: Other specified schizophrenia
• 6A20.Z: schizophrenia, unspecified

Course specifiers are organized to characterize both the longitudinal course (first episode, multiple episodes, continuous) and the cross-sectional status in the past month (currently symptomatic, in partial remission, in full remission). Course qualifiers can also become automatically coded together with the symptom qualifiers (see Slide 29), e.g., schizophrenia – first episode – currently symptomatic (6A20.00), positive symptoms (6A25.0), severe (XS25): 6A20.00/6A25.0&XS25.
