The main purpose of this legislation is to improve the scheduling process for veterans seeking medical care through the Department of Veterans Affairs (VA). It aims to establish a clear and comprehensive standard for the time it takes between when a veteran is referred for care and when they actually receive that care. This is intended to enhance the efficiency and accessibility of healthcare services for veterans. Key provisions of the legislation include the requirement for the Secretary of Veterans Affairs to create a standard for the timing of referrals and appointments.
