This bill mandates that the Secretary of Defense and the Secretary of Veterans Affairs develop and implement action plans to enhance the availability of care for enrolled veterans at Department of Defense (DoD) facilities. These plans are designed to strengthen resource sharing between the departments, improve communication, and increase the utilization of military medical treatment facilities with excess capacity or space. A key objective is to boost case volume for medical education programs and expand access to care for veterans in areas near such DoD facilities. The required action plans must include provisions for cross-credentialing healthcare providers, ensuring expedited access for VA staff and veterans to DoD installations, and designating a coordinator at each facility. They also mandate mechanisms for monitoring effectiveness, integrating information technology systems for seamless data sharing, and establishing an oversight plan for adverse medical events. These plans require approval from the VA-DoD Joint Executive Committee, local installation commanders, and relevant VA medical center directors before submission to Congress. To ensure patient safety and accountability, the bill establishes a secure complaint process for veterans, mandates documentation and quarterly review of complaints and adverse events, and requires referral of misconduct allegations to the Offices of Inspector General. The Secretaries must submit these plans to Congress and provide annual briefings detailing implementation progress, patient numbers, costs, and system effectiveness. This section is set to terminate on September 30, 2028, and clarifies that veterans are not compelled to seek care at DoD facilities.
