WASHINGTON — On the eve of Veterans Day, the Veterans Affairs Department announced a reorganization Monday designed to make it easier for veterans to gain access to the department and its maze-like websites.

VA Secretary Robert McDonald called the restructuring the largest in the department’s history and said it will bring a singular focus on customer service to an agency that serves 22 million veterans.

The VA has been under intense scrutiny since a whistleblower reported last spring that dozens of veterans may have died while awaiting treatment at the Phoenix VA hospital, and that appointment records were manipulated to hide the delays.

A report by the department’s inspector general said workers falsified waitlists while their supervisors looked the other way or even directed it, resulting in chronic delays for veterans seeking care and bonuses for managers who appeared to meet on-time goals. The report identified 40 patients who died while awaiting appointments in Phoenix.

As part of the restructuring announced Monday, the VA will hire a chief customer service officer and simplify the way it is organized to deliver health care and other services, McDonald said.

For instance, the department will create a single customer service structure with a limited number of regional divisions that will apply to all aspects of the agency, from health care to benefits, loan centers and even cemetery plots. The VA now has nine separate regional structures of varying size and at least a dozen websites, many with their own user names and passwords.
