The Department of Veterans Affairs (VA) provides benefits to veterans who meet certain eligibility rules. Benefits to veterans range from disability compensation and pensions to hospital and medical care. VA provides these benefits to veterans through three major operating units: the Veterans Health Administration (VHA), the Veterans Benefits Administration (VBA) and the National Cemetery Administration (NCA). VHA is primarily a direct service provider of primary care, specialized care, and related medical and social support services to veterans through an integrated health care system.
