An internal analysis by the Trump administration concludes that 31 states would lose federal money for health coverage under Senate Republicans’ latest effort to abolish much of the Affordable Care Act, with the politically critical state of Alaska facing a 38 percent cut in 2026.

The report, produced by the Office of the Actuary within the federal Centers for Medicare and Medicaid Services, focuses on the final year of a block grant that states would receive under the Cassidy-Graham legislation. It shows that government funding for such health insurance would be 9 percent lower overall in 2026 under the plan than under current law.

The predicted loss is less than that forecast by three independent analyses of the bill’s impact in recent days, but the internal numbers show a similar checkerboard of states that would be big winners and equally big losers. The states that expanded their Medicaid programs under the ACA would be hit with the greatest reversals of federal aid.

According to the CMS data, first reported Thursday night by Axios, the greatest winners in 2026 would be Mississippi and Kansas, where federal health-care funding would more than triple and double, respectively. On the other hand, Connecticut’s aid would be cut by just over half.

The method used by federal officials to predict the bill’s effects on spending to states differs from that of another major analysis released earlier on Thursday by the Kaiser Family Foundation. The latter concluded that 35 states would lose $160 billion under the bill. The Kaiser study, like two earlier this week, looked at the cumulative effect from 2020 to 2026, while the administration’s looked only at the first and last years in that time frame.

The administration's figures also show that the fortunes would differ sharply in the home states of the legislation's two primary sponsors, Sens. Bill Cassidy (R-La.) and Lindsey O. Graham (R-S.C.). Federal funding for coverage would plunge by 41 percent in Louisiana, whose health secretary has publicly criticized the bill, while it would grow by 126 percent in South Carolina.

A Health and Human Services Department spokesman did not respond Thursday night to a request for comment.

A few sentences embedded in the 140-page Cassidy-Graham legislation would allow Alaska to avoid a reduction in government funding. A potential Republican holdout on the measure, Sen. Lisa Murkowski, has been negotiating privately this week with Senate GOP leaders.

Neither Murkowski nor the state’s junior senator, Dan Sullivan (R), have disclosed how they would vote if the bill is brought before the Senate next week, as Majority Leader Mitch McConnell (R-Ky.) maintains he will do.

It remained unclear late Thursday whether McConnell can amass the 50 votes needed under special budget procedures expiring Sept. 30 that would allow the measure to pass with a simple majority (aided by a tiebreaking vote by Vice President Pence). Given a previous bill's dramatic last-minute failure in July, with crucial opposition by Murkowski, some Republicans say they do not believe leaders will move it forward unless its passage is certain.

The courting of Alaska’s senior senator comes as intense efforts by advocates and critics to sway opinion shift to outside Washington.

At home in South Carolina, Graham is doing television and radio interviews and planning to call fellow senators and others to try to build support. “Phone firmly planted to his cheek,” his spokesman said.

Who’s for and against the Cassidy-Graham bill

Only one Republican senator is holding sessions with constituents on the measure. At a town hall meeting Thursday in Charles City, Iowa, Sen. Joni Ernst said she was "leaning yes." She characterized the plan as the only viable alternative to what she called the ACA's failures.

When audience members asked about the bill’s cuts to Medicaid spending, Ernst emphasized that spending would increase, just at a slower pace than under the current law.

The pending bill would kill central features of the ACA, including its insurance subsidies, coverage requirements for individual Americans and large businesses, and benefits and other rules for health plans sold in marketplaces created under the law. Instead, in a devolution of unprecedented scale, a smaller amount of health-care money would be reshuffled around the country as block grants for much of the coming decade, with states having great freedom on how to spend it.

“By cutting and dramatically redistributing federal funds and asking each state to come up with their own health system, this bill runs the risk of a free-for-all with confusion and potentially chaos for many years to come,” Kaiser President Drew Altman said.

Kaiser calculates an overall reduction of $160 billion between 2020, when most of the legislation’s changes would begin, and 2026, when it would stop funding the block grants.

It estimates that non-Medicaid expansion states — all but one led by Republicans — would gain an average of 12 percent during that period.

The nation’s Medicaid directors came out against the legislation on Thursday, issuing a statement that said the plan poses “significant challenges,” would “undermine” many states’ efforts to improve their programs and “fail to deliver on our collective goal of an improved health care system.”

The statement from the board of the National Association of State Medicaid Directors noted that the bill would “completely restructure” Medicaid, which accounts for 25 percent of the average state budget, and would require every state to develop policies and infrastructure by 2020 to use the block grant it would receive under the plan. “The vast majority of states will not be able to do so within the two-year time frame envisioned,” the statement said.

Each of the analyses show that, regardless of whether Congress renewed spending for the block grants after 2026, federal aid for Medicaid would plummet nationwide, because the program’s entitlement funding would be replaced with a per-person cap. And over time, annual increases under that new method would tighten.

The specific provision in the bill that would help Alaska would exempt “low-density” states from the per-person cap if their block grants would drop or stay level.

Alaska is one of the few states in which officials are doing their own assessment of the legislation’s effects. Gov. Bill Walker (I) joined nine other governors this week in sending a letter to Senate leaders to express their opposition to the Cassidy-Graham bill in its current form.

In an interview Thursday, Walker said, “I’m concerned about protecting Alaskans, and my comfort level is just not there yet.”

Murkowski’s office did not respond to a request for comment. A spokesman for Sullivan said he will comment “when the final draft is released.”

Asked about a report about a new draft of the bill with Alaska-specific tweaks, Cassidy spokesman Ty Bofferding responded, “No changes of any kind have been finalized.”
