About F25.8

F25.8 is the ICD-10-CM diagnosis code for other schizoaffective disorders. It belongs to category F25 (schizoaffective disorders), block F20-F29 (schizophrenia, schizotypal, delusional, and other non-mood psychotic disorders) and chapter 5 (mental, Behavioral and Neurodevelopmental disorders). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within F25, choose F25.8 (Other schizoaffective disorders) only when documentation doesn't support a more specific option: schizoaffective disorder, bipolar type (F25.0), schizoaffective disorder, depressive type (F25.1) and schizoaffective disorder, unspecified (F25.9).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 885 (Psychoses, relative weight 1.3901), in MDC 19 (Mental Diseases and Disorders), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 295.70 (schizoaffective disorder, unspecified).
