Utah residents may have thought they were done fighting about Medicaid expansion last November. But when Utah lawmakers opened a new legislative session in late January, they began pushing through a bill to roll back the scope and impact of an expansion that voters approved in a ballot measure.

“We voted for this on Nov. 6. We were very clear about what we wanted,” said Andrew Roberts, a spokesman for Utah Decides, the group that organized the Medicaid expansion referendum, known as Proposition 3.

The voter-approved measure would extend coverage to 150,000 uninsured people in the state.

“We are frustrated, and I think Utahns are frustrated,” Roberts said.

That frustration led his group to hire a billboard truck to drive in circles around the Capitol building and through the snowy streets of Salt Lake City and its suburbs. Signs on the sides of the truck flash phrases in LED lights, including “Support democracy. Support Utah’s vote.” A looping video advertisement urges residents to call lawmakers “who don’t respect the will of the people.”

After six years of talking about Medicaid expansion, voters approved the ballot measure on Nov. 6, with 53 percent in favor. But the issue erupted again when the legislative session started Jan. 28.

Similar legislative efforts to curtail expansion are also happening in Idaho, where voters passed a Medicaid expansion initiative in November. Sixty-one percent of voters were in favor. Idaho lawmakers are considering ways to scale that program back.

In politically and fiscally conservative Utah, legislators argue the 0.15 percent non-food sales tax that voters approved won’t be enough to pay for Medicaid expansion. So they’ll pass an expansion, but only a very limited one.

Voters “wanted Medicaid expansion, and that’s what we’re doing,” said Republican state Sen. Allen Christensen. But, he added, the voters “didn’t fill in the proper blanks. We are filling in those blanks for them. They are not obligated to balance the budget. We are.”

Christensen is leading the rollback effort in Utah. His alternative proposal, SB 96, would cap the number of individuals who would qualify for Medicaid, add work requirements and lower the annual income limit. Proposition 3 supporters had wanted the coverage available for people who made up to 138 percent of the federal poverty level, or nearly $17,000 a year. But Christensen’s bill would offer Medicaid coverage only to people who made less than 100 percent of the federal poverty level, or about $12,000 for an individual.

Making those changes would require the state of Utah to get approval for two federal waivers from the federal Centers for Medicare & Medicaid Services. Proposition 3 supporters point out that similar requests from other states have been denied.

“From the perspective of voters, I think voters have a right to be furious right now,” said Matt Slonaker, executive director of the Utah Health Policy Project, another group that has supported Medicaid expansion.

Slonaker said changing the scope of Proposition 3 would mean fewer people getting health coverage, and the state would receive less money from the federal government. He also fears it could make voters feel disillusioned.

“Why would voters ever want to pursue ballot initiatives and direct democracy if the legislature’s just going to repeal it anyway?” Slonaker asked.

While some Utah lawmakers, such as Christensen, describe being “philosophically opposed” to Medicaid expansion, much of the political debate in Utah is about how much expansion will cost, and whether the new sales tax will pay for it. Supporters point to the fiscal experience of other states.

“You should think of Medicaid expansion as no different than if you said, ‘Oh, hey, somebody’s going to go open up a factory,’” said Bryce Ward, an economist at the University of Montana, in Missoula. “And that factory is going to bring, in the case of Montana, $600 million of outside money into the state that we’re going to pay to workers here.”

Ward recently published a report on the economic impacts of Medicaid expansion in Montana during the first two years of that program. He said it brought in about $600 million dollars in new funds to the state per year. That money supported about 6,000 jobs, he added, or about $350 million in additional income for residents.

Ward said states like his also can take advantage of savings, because Medicaid expansion makes providing health care to certain groups, like prisoners, more affordable. While states do have to pay 10 percent of the cost of expanded Medicaid (the federal government covers 90 percent — a more generous “match” than traditional Medicaid), the combination of savings and economic growth meant that, in the case of Montana, the program basically pays for itself, Ward said.

“The benefits that people in Utah have is that people like me in other states have done the work trying to figure this out,” he said. “Or at least get some ballpark estimates of it.”

So far, Utah lawmakers remain unconvinced by studies like Ward’s. The bill to restrict Medicaid expansion is moving fast, and could reach the governor’s desk as soon as next week.
