A new study says that expanding Medicaid in Ohio under the federal Affordable Care Act could net the state $1.4 billion over the next decade. The findings say most of that money would come to Ohio in the early years of the Medicaid expansion. But the study released Tuesday by a nonpartisan health policy organization also notes that the savings would dwindle and even out by 2022. That's when Ohio's share of the Medicaid price tag increases. Ohio Gov. John Kasich is to decide soon whether to expand Medicaid and its health care services for poor and disabled people. The report says that about 456,000 uninsured Ohioans would gain health care coverage by 2022 if the state expands Medicaid to cover more people just above and below the poverty line.
