Anxiety ICD-10 codes

There is no single ICD-10 code for anxiety. The code depends on the diagnosis. Generalized anxiety disorder is F41.1, panic disorder is F41.0 and social anxiety disorder codes to F40.10. Anxiety with no more specific diagnosis is F41.9, Anxiety disorder, unspecified, which is where the ICD-10-CM index sends the term anxiety on its own.

Which code do I use?

F41.1 vs F41.9
F41.1 is generalized anxiety disorder, a specific diagnosis. F41.9, Anxiety disorder, unspecified, is for anxiety the record doesn't specify further. The tabular list puts anxiety NOS under F41.9, and DSM-5-TR uses F41.9 for unspecified anxiety disorder.
F41.0 vs F40.01
Panic disorder is F41.0. Panic disorder with agoraphobia is F40.01, and F41.0 has an Excludes1 note for it, so a claim reports one or the other.
F41.8 vs F43.23
Mixed anxiety and depressive disorder is F41.8. When anxiety and depressed mood are a reaction to a stressor and the clinician diagnoses adjustment disorder, the code is F43.23.
F40.10 vs F40.11
Social anxiety disorder is an inclusion term under F40.1. F40.10 is social phobia, unspecified, which DSM-5-TR uses for social anxiety disorder. F40.11 is social phobia, generalized.
