Encouraging the Prioritization of the Most Vulnerable Act This bill amend title XI (General Provisions) of the Social Security Act to require the Centers for Medicare & Medicaid Services (CMS), in approving Medicaid demonstration projects, to: post on its website information regarding how CMS prioritizes projects that have been proven effective in improving care and outcomes with respect to uninsured, Medicaid-eligible, or low-income individuals; collect, from a participating state, available data regarding the quality of care or health outcomes with respect to individuals served; post on its website information regarding how a project is not duplicative of any federal program or funding opportunity; and collect, from a participating state, an analysis of the degree to which such projects displace private and charitable sector efforts to improve care and outcomes with respect to uninsured, Medicaid-eligible, or low-income individuals.
