This legislation, titled the Sharing Essential Resources for Veterans Everywhere Act or SERVE Act, directs the Secretary of Defense and the Secretary of Veterans Affairs to develop and implement comprehensive action plans. These plans are designed to significantly improve the availability of healthcare for veterans by fostering greater collaboration and resource sharing between Department of Defense (DoD) and Department of Veterans Affairs (VA) facilities. The primary goals include strengthening existing sharing authorities, enhancing communication between the agencies, and increasing the utilization of military medical treatment facilities that have excess capacity or space. The required action plans must incorporate several key elements to facilitate seamless care. These include provisions for cross-credentialing and privileging of healthcare providers to allow them to work in both DoD and VA facilities, and expedited access to DoD installations for VA staff and enrolled veterans. Each covered facility will also designate a coordinator to serve as a liaison and lead the plan's implementation, alongside mechanisms for ongoing monitoring, performance goal setting, and data collection. Furthermore, the bill mandates the prioritized integration of relevant information technology and other systems to enable seamless information sharing, medical record referrals, and billing processes between the departments. Before implementation, action plans require approval from the co-chairs of the VA-DoD Joint Executive Committee, the local installation commander, and the relevant VA medical center director. The Secretaries must also maintain a publicly available list of all sharing agreements and ensure a lead coordinator is present at each facility with such an agreement. To safeguard patient well-being, the legislation establishes robust patient safety and accountability measures. This includes a secure complaint process for enrolled veterans, designed to protect confidentiality and prohibit retaliation, with all complaints transmitted to both departments. Records of all complaints, adverse events, and safety incidents must be maintained and jointly reviewed quarterly by designated officials from both the DoD and VA. Any allegations of abuse, neglect, or misconduct involving DoD personnel in veteran treatment must be promptly referred to the Offices of Inspector General for both departments. Pending investigation, the Secretary of Veterans Affairs may suspend referrals to the provider or facility concerned. The Secretaries are required to submit completed action plans to Congress within 30 days and provide annual joint briefings detailing implementation progress, patient numbers, costs, and the effectiveness of oversight mechanisms, with the provisions of this section set to terminate on September 30, 2028.
