ICD-10 Code F43.22 – Adjustment disorder with anxiety (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F43.22 – Adjustment disorder with anxiety
What it is
F43.22 identifies an adjustment disorder in which anxiety is the main reaction to an identifiable stressor. The symptoms are out of proportion to the stressor and cause distress or impaired functioning.
Clinical signs
You may see excessive worry, nervousness, tension, or fear after a recent life event or change. Clinical features vary; refer to documentation for timing, severity, and functional impact.
When to use this code
Use this code when the record clearly links anxiety symptoms to a specific psychosocial stressor and the clinician diagnoses adjustment disorder with anxiety. It fits cases where the reaction is clinically significant but not better explained by another anxiety disorder. Document the stressor and the relationship to symptom onset.
Do not use for
Do not use F43.22 for generalized anxiety disorder, panic disorder, or anxiety symptoms without an identified stressor. Check documentation if the chart does not clearly support an adjustment disorder diagnosis.
Coding tip
Confirm both the stressor and the clinician’s exact diagnosis before assigning F43.22.
