Other specified anxiety disorders

This code represents anxiety disorders that do not meet the full diagnostic criteria for more specific anxiety disorders (e.g., panic disorder, generalized anxiety disorder, social anxiety disorder) but still present with significant anxiety symptoms. It encompasses conditions where the primary feature is anxiety, but the presentation is atypical or falls outside established categories.

Use this code when documentation clearly indicates an anxiety disorder that is specified by the clinician but does not fit into other defined ICD-10-CM anxiety categories. This often includes presentations like mixed anxiety-depressive disorder (when anxiety is predominant and depression is subthreshold), or anxiety symptoms related to a specific situation not covered by phobias. The medical record should specify the nature of the anxiety.

• Avoid using this code as a default for unspecified anxiety; ensure the documentation specifies why it's "other specified."
• Differentiate from F41.9 (Anxiety disorder, unspecified) which is used when no further detail is provided.
• Consider sequencing if anxiety is secondary to another mental health condition; the primary diagnosis should be listed first.
