Trump Administration Medicaid Rules Will Deepen Coverage Losses, Think Tank Warns

CBPP Flags Expansive CMS Policies That Threaten Medicaid Enrollees

The Center on Budget & Policy Priorities (CBPP) has issued a sharp warning that the Trump Administration is piling a second wave of Medicaid cuts on top of last year’s Republican reconciliation law. While the 2025 statute already slashed more than $900 billion from the program, taking coverage from millions, a series of recent CMS rulemakings will deepen the harm and place additional strain on state budgets, the think tank says.

Chief among its concerns is an interim final rule implementing the law’s work requirement. The statute carved out a “medical frailty” exemption for people with serious illnesses such as cancer, substance use disorders, and mental health conditions. But CBPP contends the rule made last-minute changes that will cause many with genuine medical needs to lose coverage. It also complicates states’ ability to meet a January 2027 deadline in a way that would protect eligible individuals.

Two separate proposed rules are attacked for exceeding the reconciliation law’s mandates. One would cap Medicaid managed care and fee-for-service payments far more aggressively than Congress intended. CMS itself estimates the rule will cut federal Medicaid funding by more than $510 billion over ten years—three times the $149 billion the Congressional Budget Office projected for the statutory provisions. The measure also extends limits to U.S. territories and eliminates a methodology states use to authorize rate increases under state directed payments.

A second rule targeting health-care related provider taxes would impose restrictions beyond those in the 2025 law. It extends new limits to taxes on entities such as health insurers, imperiling a key source of state Medicaid revenue. CMS projects $245 billion in federal cuts over a decade, above the law’s $191 billion CBO score. Additionally, the administration has released guidance on section 1115 demonstrations that CBPP warns will add significant administrative burdens and jeopardize funding for coverage expansions and delivery innovations.

Why the New Rules Go Far Beyond the 2025 Reconciliation Law

The Work Requirement Rule Narrows the Medical Frailty Safety Net

The reconciliation law intended to exempt people with acute medical conditions from having to prove work or face coverage termination. But the interim final rule’s late policy shifts—details of which CBPP does not specify but says will raise the number of denials—suggest the administration is using the regulatory process to maximize disenrollment. This matters because even with a functioning exemption, many enrollees struggle to navigate documentation requirements. A narrower definition of who qualifies as medically frail will disproportionately affect people with complex, chronic illnesses who rely on uninterrupted care.

Payment Caps Deliver a Shock to Providers and Plans

The proposed payment cap rule is arguably the most consequential. By going far beyond the statutory language, CMS is aiming for a $510 billion reduction, which would starve Medicaid managed care organizations and fee-for-service providers of federal dollars. The rule slashes state-directed payments that have been a lifeline for hospitals and clinics serving low-income communities. Its own analysis acknowledges that the cuts are deeper in expansion states, effectively punishing states that chose to extend coverage. The result, CBPP argues, will be narrower provider networks, longer wait times, and degraded access—outcomes at odds with the program’s purpose.

Provider Tax Limits Will Force Painful Trade-Offs

Nearly every state uses provider taxes to help finance its Medicaid share. The new proposed rule not only deepens the statutory cuts but extends the clampdown to taxes on health insurers and other health-care entities, eroding an even broader revenue base. CMS estimates a $245 billion hit, but because the agency excluded the effect of extending limits to newly covered taxes, the real drain on state coffers is likely larger. States will be forced to choose between cutting optional benefits, slashing provider reimbursement (possibly eliminating state-directed payments altogether), or both—choices that directly harm enrollees.

1115 Guidance Adds Bureaucratic Weight When States Are Already Strained

The administration’s new approach to budget neutrality for section 1115 demonstrations piles additional administrative hurdles on states that are already implementing the 2025 law’s onerous requirements. The guidance interprets the law in a more sweeping manner than required, putting at risk innovations in coverage, benefit design, and delivery. Because many states run large portions of their Medicaid programs through 1115 waivers, virtually every state will feel the pressure, potentially reversing years of progress on substance use treatment, housing supports, and other community-based services.

What States and Advocates Should Do Next

• Model the true fiscal impact: State Medicaid agencies should use CMS’s own $510 billion estimate to quantify how the proposed payment caps would shrink their federal funding, then compare that with the CBO’s $149 billion baseline to frame the gap for state lawmakers.
• Submit detailed comments: States and provider associations must file comments on the proposed rules before their respective deadlines, highlighting specific examples of how extended limits would erode access and destabilize safety-net providers.
• Plan for lost provider tax revenue: Budget offices should begin scenario planning for a scenario in which provider taxes on health insurers are restricted or eliminated. Identify which optional benefits or rate cuts would cause the least harm to enrollees if the revenue is not replaced.
• Prepare for the work requirement deadline: With January 2027 looming, states need to map which current enrollees might fall outside the narrowed medical frailty exclusion and design outreach programs to help individuals document their exemptions before coverage is terminated.
• Press for a legislative fix: CMS rulemaking cannot undo statutory cuts. Governors and legislators should urge Congress to revisit the Medicaid provisions in the 2025 reconciliation law, as only a legislative reversal can fully restore funding and flexibility.
