Code Description

ICD-10 F43.22 is a billable code used to indicate a diagnosis of adjustment disorder with anxiety.

Key Diagnostic Point:

Adjustment disorder with anxiety is a psychological condition that arises in response to a significant life stressor or change, leading to emotional or behavioral symptoms that are disproportionate to the severity of the stressor. Patients may experience excessive worry, nervousness, and anxiety that can interfere with daily functioning. Symptoms typically manifest within three months of the identifiable stressor and can include restlessness, difficulty concentrating, and sleep disturbances. Unlike generalized anxiety disorder, the anxiety in adjustment disorder is directly linked to the stressor and tends to resolve once the individual adapts to the new situation or the stressor is removed. Treatment often involves psychotherapy, such as cognitive-behavioral therapy, and may include pharmacotherapy for symptom relief. It is crucial for healthcare providers to differentiate adjustment disorder from other anxiety disorders, such as PTSD or OCD, which have distinct diagnostic criteria and treatment approaches.
