F20.8 — Other schizophrenia
F20.8 is a non-billable header ICD-10-CM code for other schizophrenia. It cannot be billed on its own: choose one of the more specific child codes below.
Excludes1 inherited from the categories above F20.8
These are not written on F20.8, but they bind it: a note on a category applies to every code beneath it. Billing F20.8 with anything listed here is a denial.
Excludes2 inherited from the categories above F20.8
Also inherited, and the opposite of Excludes1: these conditions are not part of F20.8, but a patient can have both, so you may code both.
Other codes that can never be billed with F20.8
These codes carry an Excludes1 note pointing at F20.8. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading F20.8 alone.

Risk adjustment
F20.8 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
Code history
F20.8 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
