Some Republican lawmakers — still reveling in Tuesday’s statewide election sweep — are proposing an unprecedented solution to the state’s estimated $25 billion budget shortfall: dropping out of the federal Medicaid program.

Far-right conservatives are offering that possibility in post-victory news conferences. Moderate Republicans are studying it behind closed doors. And the party’s advisers on health care policy say it's being discussed more seriously than ever, though they admit it may be as much a huge in-your-face to Washington as anything else.

“With Obamacare mandates coming down, we have a situation where we cannot reduce benefits or change eligibility” to cut costs, said State Rep. Warren Chisum, R-Pampa, the veteran conservative lawmaker who recently entered the race for speaker of the Texas House. “This system is bankrupting our state,” he said. “We need to get out of it. And with the budget shortfall we’re anticipating, we may have to act this year.”

The Heritage Foundation, a conservative think tank, estimates Texas could save $60 billion between 2013 and 2019 by opting out of Medicaid and the Children’s Health Insurance Program, dropping coverage for acute care but continuing to fund long-term care services. The Texas Health and Human Services Commission, which has 3.6 million children, people with disabilities and impoverished Texans enrolled in Medicaid and CHIP, will release its own study on the effect of ending the state’s participation in the federal match program at some point between now and January.

State Rep. John Zerwas, R-Simonton, an anesthesiologist who authored the bill commissioning the Medicaid study, said early indications are that dropping out of the program would have a tremendous ripple effect monetarily. He is not ready to discount the idea, he said, but he worries about who would carry the burden of care without Medicaid’s “financial mechanism.”

“Because of the substantial amount of matching money that comes from the federal government, there’s an economic impact that comes from that,” Zerwas said. “If we start to look at what that impact is, we have to consider whether it’s feasible to not participate.”

State Sen. Jane Nelson, R-Flower Mound, who chairs the Senate Public Health Committee, said dropping out of Medicaid is worth considering — but only if it makes fiscal sense without jeopardizing care. Currently, the Texas program costs $40 billion per biennium, with the federal government footing 60 percent of the bill. As a result of federal health care reform, she said, millions of additional Texans will be eligible for Medicaid.

“I want to know whether our current Medicaid enrollees, and there certainly could be millions more by 2014, could be served more cost efficiently and see better outcomes in a state-run program,” Nelson said.
