About coding anxiety state neurosis
The ICD-10-CM code for anxiety state neurosis is F41.1 (Generalized anxiety disorder). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on F41.1.
Within F41 (other anxiety disorders), F41.1 is specifically for generalized anxiety disorder. Related codes cover panic disorder [episodic paroxysmal anxiety] (F41.0), other mixed anxiety disorders (F41.3), other specified anxiety disorders (F41.8) and anxiety disorder, unspecified (F41.9).
The conditions in its Excludes2 note aren't part of F41.1, but may be coded alongside it if the patient has both: neurasthenia (F48.8).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
