The U.S. Department of Veterans' Affairs (VA) currently provides disability benefits to 2.72 million veterans of U.S. military service through the Disability Compensation (DC) program. Until recently, the medical eligibility criteria for this program were the same across service eras, with the key condition being that the disability was caused or aggravated by military service. But in July of 2001, the VA relaxed the eligibility criteria for Vietnam veterans by including diabetes in the list of conditions covered by DC. This change was motivated by an Institute of Medicine report, which linked exposure to Agent Orange and other herbicides used by the U.S. military in Vietnam, to the onset of diabetes.
