About coding schizoaffective disorder
The ICD-10-CM code for schizoaffective disorder is F25.9 (Schizoaffective disorder, unspecified). The official index lists 5 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on F25.9.
Within F25, choose F25.9 (Schizoaffective disorder, unspecified) only when documentation doesn't support a more specific option: schizoaffective disorder, bipolar type (F25.0), schizoaffective disorder, depressive type (F25.1) and other schizoaffective disorders (F25.8).
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.
