The purpose of this legislation is to change how the federal government provides financial support for Medicaid, particularly for low-income adults. It aims to phase out the enhanced federal funding that currently helps states cover medical assistance costs for these individuals. Key provisions of this legislation include a gradual reduction of the federal match rate for states that provide Medicaid to low-income adults. The bill specifies that starting in 2027, the federal funding percentage will decrease each year until it aligns with the standard federal medical assistance percentage.
