Proposed changes to who qualifies for Medicaid coverage could jeopardize more than half the 770 million federal dollars Ohio is to get from President Bush’s tax cut. An Ohio Department of Job and Family services official says the agency is studying language in the federal law that says that state must maintain eligibility as it exists. Spokesman Jon Allen says the state wants to know if changing eligibility within the state budget still would allow the state to get the 400,000,000 dollars earmarked for the poor. The budget takes effect July first. Governor Taft has proposed limiting which adults are eligible for Medicaid as part of his plan to stymie soaring Medicaid costs that threaten to bankrupt the state.
