Final answer:
The primary care provider within a health maintenance organization or a similar managed care system usually manages a beneficiary's health care, but for veterans, the Department of Veterans Affairs often takes on this coordination role.
Step-by-step explanation:
The individual responsible for coordinating and managing all of a beneficiary's health care, unless there is an emergency, is typically a primary care provider (PCP) within a health maintenance organization (HMO) or a similar managed care system. In situations where a beneficiary is a veteran, this coordination role can also be specifically managed by a governmental agency like the Department of Veterans Affairs (VA), which oversees the services provided to U.S. veterans, including health care services and benefits programs. Nonprofit health organizations and private hospitals may also participate in managed care systems, but the overarching coordination is generally under the purview of an HMO or a governmental agency tasked with the provision and management of health services for specific groups like veterans.
