The Medicare for America Act of 2019 (H.R. 2452) was introduced into the House of Representatives on May 1, 2019. If enacted, this legislation automatically would enroll much of the U.S. population into a single federal comprehensive health insurance program. A study by KNG Health Consulting estimates that it would result in nearly one in four workers previously offered employer-sponsored insurance losing access to it by 2023 and one in three by 2032.
