Trump's New Medicaid Waiver Test Threatens Arkansas Coverage and Hospital Funding

Why Arkansas's Medicaid Waiver Is Being Forced Into a Redesign

Roughly 200,000 low-income adults in Arkansas face a coverage redesign after the Centers for Medicare & Medicaid Services told state officials their 13-year Medicaid waiver cannot be renewed under new budget-neutrality rules taking effect in January. Arkansas is now seeking a two-year extension after CMS indicated it would not grant the five-year renewal the state had requested.

The waiver, first approved in 2013, allowed Arkansas to buy Affordable Care Act marketplace plans from private insurers for adults covered by Medicaid expansion instead of placing them in traditional Medicaid. That private option cut the state's uninsured rate by nearly half and offered enrollees broader access to doctors, but it also cost more than standard fee-for-service Medicaid. If the waiver lapses, Arkansas officials say they will continue expanded eligibility through regular Medicaid law, a change likely to reduce the number of providers available to enrollees.

The conflict extends beyond Arkansas. Nearly every state runs at least one Medicaid waiver, and about a third of the roughly $600 billion in federal Medicaid and CHIP spending in 2024 supported waiver-created programs, according to CMS. Arkansas is one of a dozen states with waivers expiring December 31 now facing the additional restrictions; Georgia and California are also in renewal talks with CMS.

Arkansas's timeline is further compressed by two January events: waiver enrollees must begin proving they work or qualify for an exemption under the One Big Beautiful Bill Act, and Centene will stop participating in the state's private option at the end of the year. Governor Sarah Huckabee Sanders's office says it is negotiating a temporary extension and preparing what it calls a sustainable model for conservative healthcare reform.

The New Waiver Test's Ripple Effects Across States and Hospitals

CMS frames the change as straightforward enforcement of a statutory requirement that waivers not increase federal spending; the agency said in June it would not approve or renew waivers unless certified to be budget-neutral in advance. Critics argue the real effect is a backdoor Medicaid reduction. Boston University health law professor Nicole Huberfeld said the administration is using arcane regulatory processes, which could leave enrollees unsure who is responsible if their coverage changes.

Why Arkansas's Private-Option Model Is the First Test Case

Arkansas is uniquely exposed because its waiver was explicitly built around a more expensive private-plan structure. A 2014 Government Accountability Office report found the approved three-year spending limit for the waiver was nearly $800 million above the state's projected traditional Medicaid costs. Under the new prospective budget test, that cost difference is no longer tolerated; CMS must certify before renewal that the waiver will not increase federal spending, not review after the fact.

The state has accepted that a lapse would not end expansion, but would force expanded coverage into standard Medicaid. That is a significant operational change because private plans generally pay providers more, attracting a wider network. The state's own officials have said the fallback would likely leave enrollees with fewer doctors and other providers.

Georgia, California and the End of Automatic Renewals

The new hurdle affects other waiver states immediately. Georgia's waiver, which added about 18,000 low-income residents, and California's waiver for food and housing services both expire at the same December 31 deadline. Both states told KFF Health News they are still trying to renew. Manatt managing director Alice Lam said states will have to clear more bureaucratic requirements, which could produce fewer benefits or reduce the number of people eligible for Medicaid.

The administration has also stopped renewing waivers for job training and continuous eligibility in 2025, signaling that long-standing waivers cannot assume they will be extended as they were under previous administrations. That shifts planning from routine renewal to a negotiation over what states must give up to keep federal flexibility.

Safety-Net Hospitals and the Financial Fallout

Robert Nelb, policy director at America's Essential Hospitals, said many long-standing waivers are now at risk. The money at stake is not abstract: hospitals rely on waiver-supported funding to cover uninsured patients and improve care in their communities. He warned that the new interpretation could add upfront burdens on states and slow innovation in Medicaid.

In Arkansas, that financial risk arrives just as Centene exits the private option and the state imposes work-reporting requirements. The remaining private plan and the traditional Medicaid system will have to absorb a transition with little time before coverage changes begin.

What Arkansas and Other States Should Prepare For

For state Medicaid directors, safety-net providers and health plans, the December 31 waiver deadline and January work requirements create a compressed operational window. The specific pressure points tied to this case are:

• Arkansas must secure or replace its waiver before the December 31 expiration. The state has already scaled back its request from five years to two, and CMS has not finalized approval. If denied, Arkansas will continue eligibility through traditional Medicaid rather than private marketplace plans.
• January combines work-reporting requirements with the loss of Centene. Arkansas expansion enrollees will need to prove work or an exemption just as one of the state's two private plans exits, increasing the risk of coverage disruptions and provider-network churn.
• Georgia and California should prepare for the same renewal test. Georgia's waiver covers about 18,000 low-income residents, and California's supports food and housing services; both are still negotiating with CMS.
• Safety-net hospitals need to model the loss of waiver-supported funding for uninsured care and community improvements. Nelb said those funds directly support hospital operations, so a non-renewal would affect budgets.
• The remaining Arkansas private plan and the traditional Medicaid network must absorb the transition. With Centene leaving, thousands of enrollees could shift into a narrower provider network if the waiver is not extended.
