Adjustment Disorder is rated by the U.S. Department of Veterans Affairs under DC 9440 of 38 CFR § 4.130, DC 9440 across 6 severity tiers (0% / 10% / 30% / 50% / 70%…). Service connection requires (1) a current diagnosis, (2) an in-service event, injury, or exposure, and (3) a medical nexus opinion linking the two under 38 C.F.R. § 3.303.
Adjustment disorder is a DSM-5 trauma- and stressor-related diagnosis defined by emotional or behavioral symptoms (depressed mood, anxiety, conduct disturbance) that develop within three months of an identifiable stressor and are out of proportion to the severity of that stressor or cause clinically significant occupational or social impairment. The symptoms do not meet the full criteria for another mental disorder such as major depression or PTSD, and by definition resolve within six months after the stressor or its consequences end. When the stressor is chronic or its effects persist, the disturbance can become protracted and produce sustained impairment.
