Anorexia Nervosa is rated by the U.S. Department of Veterans Affairs under DC 9520 of 38 CFR § 4.130, DC 9520 across 5 severity tiers (0% / 10% / 30% / 60% / 100%). 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.
Anorexia nervosa is a DSM-5 eating disorder marked by restriction of energy intake that drives a significantly low body weight, an intense fear of gaining weight or persistent behavior that interferes with weight gain, and a distorted perception of body weight or shape. DSM-5 recognizes a restricting type and a binge-eating/purging type, and severity is graded by current BMI. Medically it can produce serious complications including amenorrhea, bradycardia, electrolyte derangement, and bone-density loss, which is why the VA rates it on physical impact rather than the mental-impairment scale.
