Anxiety ICD-10 code

The ICD-10-CM code for anxiety is F41.9 anxiety disorder, unspecified. It is billable and valid for submission on a claim. There are 16 related codes, and which one you use depends on what the documentation supports.

Also written as gad, generalized anxiety.

The mistake coders make here

F41.1 is generalised anxiety disorder specifically. F41.9 is unspecified anxiety. They are not the same, and a documented GAD diagnosis should not be coded as F41.9.
