Hospitals across the country are escalating their fight over Medicaid funding as federal regulators move to tighten payment rules after last year’s congressional cuts. The latest flashpoint is a Centers for Medicare & Medicaid Services proposal issued under Administrator Dr. Mehmet Oz that hospital groups say would drive losses far beyond what Congress enacted. At issue is how much Washington can restrict state Medicaid payment arrangements that many hospitals rely on to cover care for low-income patients.
CMS proposal puts a $681 billion figure at the center of the fight
The Centers for Medicare & Medicaid Services published the proposed rule on May 20, 2026, saying it would cap certain Medicaid state-directed payments for hospital services at Medicare-equivalent levels in expansion states and 110% of Medicare in non-expansion states, according to a CMS fact sheet. CMS said the proposal was meant to “rein in” what it described as misused Medicaid dollars and better align payments with Medicare standards, according to the agency’s May 20 press release.
Hospital groups responded by arguing the proposal goes well beyond the cuts Congress already approved in the 2025 reconciliation law. In comments dated July 21, 2026, the American Hospital Association said CMS’s own estimate projects a $510.1 billion reduction over 10 years from the proposed rule, compared with a $149.4 billion Congressional Budget Office estimate tied to the underlying statute. That gap is what hospital policy officials have described in recent reporting as roughly $681 billion more in losses than they expected once the broader law and rule are combined.
The broader financing shift is large even before the rule is finalized. KFF reported on June 15, 2026, that federal Medicaid spending through state-directed payments had reached an estimated $93 billion annually across 40 states and the District of Columbia, with hospitals accounting for 84% of that spending, or about $78 billion a year. KFF also said CMS estimated that SDP-related changes in the law and proposed rule together would reduce federal Medicaid spending by $510 billion from 2026 through 2035.
The effects would not fall evenly across the country. KFF said in an August 14, 2026, analysis that at least 37 states and the District of Columbia have Medicaid state-directed payments for hospital services that likely exceed the new federal limits once fully implemented. The largest potential reductions in federal Medicaid hospital funding were identified in California, Illinois, Kentucky, Texas, North Carolina, Louisiana, Arizona and Michigan, according to KFF.
That state-by-state variation matters because hospitals’ dependence on Medicaid supplemental payments differs widely. KFF said the eight states with the biggest potential reductions account for about half of the total estimated exposure, with California alone at $7.4 billion and Texas at $3.5 billion. The organization also said its estimates do not project actual annual hospital revenue losses, because those outcomes will depend on other coverage changes, provider tax restrictions and decisions by individual states.
What is not yet known is which hospitals within each state would absorb the largest losses if the rule is finalized as written. Neither CMS nor hospital groups have released a comprehensive national hospital-by-hospital list tied to the proposed changes. That leaves uncertainty for local providers, especially safety-net and rural hospitals, even as national trade groups warn that facilities with thin margins could face service reductions or other operating changes.
CMS has framed the proposal as part of a broader push against financing arrangements it says inflate federal costs without improving care. In its May 20 announcement, the agency said some state-directed payment structures rely heavily on intergovernmental transfers or provider taxes and argued that clearer limits are needed to protect taxpayers and reward value. CMS also pointed to a 2024 MACPAC report in explaining its concerns about how states finance a large share of these payments.
Hospital organizations say that rationale ignores how central Medicaid supplemental payments have become to keeping facilities open and offsetting low base reimbursement. The American Hospital Association said the proposed changes would make it harder for hospitals to sustain care for Medicaid patients, and KFF said financially vulnerable hospitals are more likely to be affected because they tend to serve larger Medicaid populations and operate with lower margins. KFF also noted that states have fewer tools to replace lost federal dollars because the reconciliation law imposed other financing restrictions, including on provider taxes.
For patients and communities, the practical effect is that the rule is still proposed, not final, and the precise local impact remains unsettled. Hospitals are continuing to press CMS to narrow or withdraw parts of the proposal, while federal officials have not yet issued final regulations. Until that happens, providers, state Medicaid agencies and residents are left planning around a policy fight that could reshape hospital funding well beyond the cuts Congress already enacted.
