F25.8 — Other schizoaffective disorders
F25.8 is a billable, specific ICD-10-CM code for other schizoaffective disorders. It is valid for submission on a claim.
Excludes1 inherited from the categories above F25.8
These are not written on F25.8, but they bind it: a note on a category applies to every code beneath it. Billing F25.8 with anything listed here is a denial.
Other codes that can never be billed with F25.8
These codes carry an Excludes1 note pointing at F25.8. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading F25.8 alone.
- F20Schizophrenia
Risk adjustment
F25.8 risk-adjusts. Under the CMS-HCC V28 model it maps to these categories:
- HCC 151 Schizophrenia0.511 RAF
- HCC 151 Schizophrenia0.511 RAF
Coefficient shown for the Community Non-dual Aged segment. A higher HCC in the same hierarchy will suppress this one, so capturing it does not always add score.
Medicare coverage
F25.8 is named in 18 Medicare coverage policies — 17 listing it as supporting medical necessity, and 1 listing it as NOT covered. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.

How F25.8 is indexed
