About F32.A
F32.A is the ICD-10-CM diagnosis code for depression, unspecified. It belongs to category F32 (depressive episode), block F30-F39 (mood [affective] 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 F32, choose F32.A (Depression, unspecified) only when documentation doesn't support a more specific option: major depressive disorder, single episode, mild (F32.0), major depressive disorder, single episode, moderate (F32.1), major depressive disorder, single episode, severe without psychotic features (F32.2), major depressive disorder, single episode, severe with psychotic features (F32.3), major depressive disorder, single episode, in partial remission (F32.4), major depressive disorder, single episode, in full remission (F32.5), other depressive episodes (F32.8) and major depressive disorder, single episode, unspecified (F32.9).
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 881 (Depressive Neuroses, relative weight 0.895), 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 was added in FY2022, effective October 1, 2021.
