H.R. 6595 directs the Defense Department and Veterans Affairs to develop action plans that improve veteran access to care at military medical treatment facilities. The bill requires these two departments to work together to share resources, increase utilization of military hospitals with available capacity, streamline communication, and allow doctors from each department to work across both systems. Each facility with a sharing agreement must designate a coordinator, establish performance goals, integrate computer systems for seamless records sharing, and create a secure process for veterans to report complaints about their care. The departments must submit the completed action plans to Congress within 30 days and provide annual progress briefings that include patient safety data, the number of providers cross-trained, costs, and information technology integration efforts. The bill includes strong oversight provisions to track adverse events and misconduct allegations, with authority to temporarily suspend veteran referrals to problematic facilities during investigations. The legislation is set to expire on September 30, 2028.
