ICD-10 Code F43.29 – Adjustment disorder with other symptoms (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F43.29 – Adjustment disorder with other symptoms
What it is
F43.29 identifies an adjustment disorder where the reaction to an identifiable stressor does not fit a more specific subtype. Use it when the record describes stress-related emotional or behavioral symptoms, but not mainly depressed mood, anxiety, or disturbance of conduct.
Clinical signs
Clinical features vary; refer to documentation. Common findings include distress that is out of proportion to the stressor, difficulty coping, and changes in functioning after a recent life event or stressor.
When to use this code
Use F43.29 when the clinician documents adjustment disorder with symptoms such as irritability, tearfulness, sleep problems, or mixed emotional response, and no more specific adjustment disorder code applies. It is appropriate when the stressor and symptom relationship is clearly documented. Check documentation if the presentation is vague.
Do not use for
Do not use this code for normal stress reactions without a diagnosed disorder, or when the record supports a more specific adjustment disorder subtype. Do not use it if another mental health diagnosis better explains the symptoms.
Coding tip
Confirm the stressor, symptom pattern, and provider’s exact wording before assigning F43.29.
