NASHVILLE, Tenn. (AP) — The federal Medicaid leader has declined to say whether imposing work requirements on certain beneficiaries is better suited for states that expanded Medicaid than those that didn't, saying her agency is assessing state proposals case-by-case. Centers for Medicare & Medicaid Services Administrator Seema Verma told reporters Thursday the program is about helping people rise out of poverty. President Donald Trump's administration has approved Kentucky, Indiana and Arkansas plans.
