Imposing work requirements on Medicaid beneficiaries will likely disrupt health care for as many as 118,000 low-income Americans, leaving them exposed to potentially catastrophic medical costs, a Commonwealth Fund study by Sara Collins, Sherry Glied, and Adlan Jackson finds. That projection is double the number who would normally be expected to disenroll from Medicaid over a two-year period because of fluctuations in income, administrative barriers, or life changes.
