TALLAHASSEE, Fla.—Florida hospital officials are lobbying lawmakers to expand Medicaid coverage to roughly 1 million residents under the federal healthcare law. A rally last week in Tallahassee came a day after a Senate panel voted against traditional Medicaid expansion and instead proposed a voucher system where patients would obtain private insurance through Florida Healthy Kids. Patients may have to pay premiums and co-payments. State funds could be used to subsidize that. A House panel has also vetoed expansion. Hospital executives said they're less concerned about the details as long as Florida draws down an estimated $51 billion in federal funds and covers more uninsured residents. Hospitals will be hit doubly hard if the state declines to expand Medicaid because the federal funding streams that hospitals rely on to pay for uninsured patients will end. Gov. Rick Scott wants to expand Medicaid coverage to roughly 1 million of Florida's poorest residents by raising eligibility as envisioned under the Patient Protection and Affordable Care Act. Scott said he was in favor of expanding Medicaid for the three years that the federal government will fund 100% of the new coverage. State economists project Florida would receive more than $51 billion over the next decade, while spending about $5.2 billion.
