Illness Anxiety Disorder (Hypochondriasis) is rated by the U.S. Department of Veterans Affairs under DC 9425 of 38 CFR § 4.130, DC 9425 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.
Illness Anxiety Disorder is a DSM-5 condition marked by persistent preoccupation with having or acquiring a serious illness, where somatic symptoms are mild or absent yet anxiety about health remains high and disproportionate. Sufferers either repeatedly check the body, seek reassurance and excessive medical testing (care-seeking type) or rigidly avoid doctors and hospitals (care-avoidant type), with the health worry lasting at least six months even when prior workups are clean. The disorder, which absorbed most of the former diagnosis of hypochondriasis, drives real functional impairment through wasted time, strained relationships, and chronic distress rather than through an underlying physical disease.
