However, Reuben also said that the fact that the funding expires next summer, after the legislature meets to set the budget in March, introduces uncertainty into those budget calculations because legislators won't know whether that $2 billion will be replaced by CMS next year.
"Leaving that hole in the budget is a problem," Reuben said.
Even with that funding, there is another $3 billion in uncompensated care provided by hospitals that could be offset by expanding Medicaid, he said.
Josh Archambault, a senior fellow at the Foundation for Government Accountability, was highly skeptical that Florida would join the ranks of 27 states and the District of Columbia that have expanded Medicaid.
"Florida would not be in my top third of states that I would expect to expand next year," Archambault said. "In Florida, everything has to go through the legislature."
In the recent fall elections, Gov. Rick Scott won re-election and Republicans retained control of both houses in the legislature, which in the past has refused to adopt Medicaid expansion.
Scott, who originally opposed expansion, later nominally supported it, but hasn't lobbied the legislature to adopt it. When asked for his current position on Medicaid expansion, a Scott spokeswoman, Jeri Bustamante, said only, "We are proud that we already have historic Medicaid reforms in Florida. We received a waiver from the federal government to make our systems more accessible and affordable to low-income people who most need access to high-quality medical care."
Archambault, whose foundation is based in Florida, said legislators there have told him they want to protect beneficiaries already covered by Medicaid, and oppose expanding the program to able-bodied, working age adults.
He also said legislators are "closely watching" the actions of the Republicans in Congress to see if they move to reduce the federal government's funding for the newly eligible under Medicaid, which would reduce the incentive to adopt expansion.
Archambault said, "I don't think that all of a sudden a wild swing is going to happen" in Florida.
