In many ways, the Veterans Health Administration (VHA), which provides health care to a great number of veterans, offers care that is as good as or better than that provided by private or non-VHA public practices. But the accessibility and quality of services vary across the system. Several studies have shown, for example, that a large number of veterans don’t receive any treatment following diagnoses of posttraumatic stress disorder, substance use disorder, or depression. Many veterans don’t know how to apply for veterans’ mental health care benefits, are unsure if they are eligible, or are unaware that mental health care benefits are available.
