This bill directs the Department of Defense and Department of Veterans Affairs to work together to create a single, unified system for credentialing and privileging medical providers across both departments. Currently, the two agencies use separate systems, which can create inefficiencies when providers work across military and veteran healthcare settings. The Secretaries of Defense and Veterans Affairs must first submit a detailed report to Congress within 120 days describing their existing systems, including what data they hold, how portable that information is, and what gaps exist in how well the systems work together. By January 1, 2027, they must jointly select one existing system to serve as the uniform standard for both departments, ensuring it can import and share provider credentials. Finally, by January 1, 2028, they must certify to Congress that the chosen system is fully implemented and operational. The bill has no specific funding amount identified in the text and affects all medical providers working in the military and veterans healthcare systems.
