About coding atypical depression
The ICD-10-CM code for atypical depression is F32.89 (Other specified depressive episodes). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on F32.89.
Within F32.8, choose F32.89 (Other specified depressive episodes) only when documentation doesn't support a more specific option: Premenstrual dysphoric disorder (F32.81).
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.
