Jessica Kensky and Patrick Downes Act This bill amends the National Defense Authorization Act for Fiscal Year 2017 to include victims of acts of terror in the evaluation and treatment of veterans and civilians at military treatment facilities. The Department of Defense (DOD) shall establish implementing procedures: (1) for outreach and communication to local medical facilities after an act of terror in the United States; (2) to coordinate and provide medical expertise to local medical facilities that are treating victims of an act of terror that caused blast related injuries, mass shooting related injuries, burn related injuries, or other serious injuries; and (3) for medical evaluations of such victims. DOD may not release a victim of an act of terror who is receiving such care to a private health care provider until a comprehensive treatment plan is communicated to the individual or his or her health care provider.
