This bill establishes the Military-Civilian Medical Surge Program within the Department of Defense, in collaboration with the Department of Health and Human Services. Its primary purpose is to enhance the interoperability and medical surge capability and capacity of the National Disaster Medical System during national emergencies, public health emergencies, or contingency operations. The program will be managed by the Institute for Defense Health Cooperation and administered in coordination with various military entities and HHS. A key provision involves establishing partnerships with public, private, and nonprofit healthcare organizations at a minimum of eight strategically selected locations, such as aeromedical or transport hubs. These partnerships aim to mobilize civilian medical personnel to quickly support military medical treatment facilities and the broader military health system during crises. Partner organizations must be critical for civilian medical responses to wartime or catastrophic events and demonstrate proficiency in areas like high-consequence infectious disease preparedness. The bill mandates annual reporting to Congress on the program's status and capabilities, while clarifying that it does not grant the Secretary of Defense control over HHS authorities regarding the National Disaster Medical System.
