Nashville Tennessean In the waning days of the Trump administration, federal officials approved a plan to convert TennCare funding to a block grant, potentially overhauling the Medicaid program providing health coverage to about one in five Tennesseans. But a TennCare block grant does not align with the health care proposal of President-elect Joe Biden, who instead campaigned on plans to improve and expand Obamacare. Biden may reverse the Tennessee block grant decision before it has any effect. For now, Tennessee is the first and only state approved to transform Medicaid in this way. Federal officials said the proposal could be a "model" for other states. Gov. Bill Lee touted the approval as a "legacy accomplishment" and a "historic day for Tennessee."
