About coding anxiety depression
The ICD-10-CM code for anxiety depression is F41.8 (Other specified anxiety disorders). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on F41.8.
Within F41, choose F41.8 (Other specified anxiety disorders) only when documentation doesn't support a more specific option: panic disorder [episodic paroxysmal anxiety] (F41.0), generalized anxiety disorder (F41.1), other mixed anxiety disorders (F41.3) and anxiety disorder, unspecified (F41.9).
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 880 (Acute Adjustment Reaction and Psychosocial Dysfunction, relative weight 0.9306), 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.
