About F20.8
F20.8 is the ICD-10-CM diagnosis code for other schizophrenia. It belongs to category F20 (schizophrenia), block F20-F29 (schizophrenia, schizotypal, delusional, and other non-mood psychotic disorders) and chapter 5 (mental, Behavioral and Neurodevelopmental disorders). It is a header code, so it can't be reported by itself; one of its 2 subcodes must be used instead.
Within F20, choose F20.8 (Other schizophrenia) only when documentation doesn't support a more specific option: paranoid schizophrenia (F20.0), Disorganized schizophrenia (F20.1), Catatonic schizophrenia (F20.2), Undifferentiated schizophrenia (F20.3), residual schizophrenia (F20.5) and unspecified (F20.9).
To report this condition, pick the subcode that matches the documentation: F20.81 (disorder) and F20.89 (schizophrenia).
Use an additional code, if applicable, to identify: other specified cognitive deficit (R41.84-).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
