Prioritizing the Most Vulnerable Medicaid Patients This bill amend title XI (General Provisions) of the Social Security Act to require the Centers for Medicare & Medicaid Services, in approving Medicaid demonstration projects, to: prioritize projects that have been proven effective in improving care and outcomes with respect to uninsured, Medicaid-eligible, or low-income individuals; require participating states to make publicly available data regarding the health outcomes for individuals to be served; ensure that projects are not duplicative of any federal program or funding opportunity; and require participating states to make publicly available an analysis of the degree to which such projects preclude private and charitable sector efforts to improve care and outcomes with respect to uninsured, Medicaid-eligible, or low-income individuals.
