Medicaid Accountability Act This bill establishes and expands certain requirements relating to Medicaid asset verification programs and other eligibility determinations. Specifically, the bill requires state Medicaid programs to verify the assets of all Medicaid applicants and recipients for purposes of determining Medicaid eligibility, rather than only of applicants or recipients who are aged, blind, or disabled. The bill also requires U.S. territories to implement asset verification programs. Such requirements must be fully implemented by FY2024. The bill also requires state Medicaid programs to apply a resource eligibility test whenever an income eligibility determination is required, based on resource limitations under the Supplemental Security Income program (currently, states are prohibited from using resource tests).
