This legislation mandates the Secretary of Veterans Affairs to establish a pilot program by October 1, 2027, enabling specific members of the Armed Forces to pre-enroll in the Department of Veterans Affairs' annual patient enrollment system. This program targets active duty service members who would be eligible for VA enrollment upon separation and are described in section 1710(e)(1)(D) of title 38, United States Code, typically encompassing combat veterans or those with certain service-connected conditions. The Secretary, in collaboration with the Secretaries of Defense and Homeland Security, must create a mechanism for these members to elect pre-enrollment during the 180-day period preceding their separation from active service. The Department of Veterans Affairs-Department of Defense Joint Executive Committee will provide annual briefings to Congress on the implementation of this mechanism. Furthermore, the Secretary of Veterans Affairs is required to submit annual reports detailing the number of participants, enrollment outcomes, and aggregated demographic information. The pilot program is authorized for three years from its enactment date. Following its termination, the Comptroller General of the United States will conduct an independent analysis of the program's effectiveness and provide recommendations to Congress.
