ICD-10-CM 2027
ICD-10 code for depression
Confirmed by the official ICD-10-CM index entry “depression (acute) (mental)”. Page updated September 29, 2026.
About coding depression
The ICD-10-CM code for depression is F32.A (Depression, unspecified). The official index lists 18 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on F32.A.
It is also searched as major depressive disorder, MDD.
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.
