Generalized anxiety disorder

F41.1 is valid for submission on a claim — CMS flags it as a billable, specific code.

Generalized anxiety disorder. In ICD-10-CM it sits in the F40–F48 block of anxiety, dissociative, stress-related, somatoform and other nonpsychotic mental disorders, alongside panic disorder (F41.0) and unspecified anxiety disorder (F41.9).

Written by Krasyn as a general orientation to the code. It is not from CMS and is not clinical or coding advice.
