About coding adjustment grief disorder

The ICD-10-CM code for adjustment grief disorder is F43.20 (Adjustment disorder, unspecified). The official index lists 7 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on F43.20.

Within F43.2, choose F43.20 (disorder, unspecified) only when documentation doesn't support a more specific option: disorder with depressed mood (F43.21), disorder with anxiety (F43.22), disorder with mixed anxiety and depressed mood (F43.23), disorder with disturbance of conduct (F43.24), disorder with mixed disturbance of emotions and conduct (F43.25) and disorder with other symptoms (F43.29).

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 882 (Neuroses Except Depressive, relative weight 0.9952), 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.
