President Donald Trump’s One Big Beautiful Bill Act is forcing states to rapidly retool Medicaid eligibility systems, and advocates warn that could worsen existing errors that already deny or misclassify eligible patients with disabilities. The stakes are large: roughly 15.5 million Medicaid enrollees have a disability, and the law is projected to strip coverage from about 7.5 million people by 2034 as states and vendors such as Deloitte race to update systems.

The Move

• KFF Health News reports that Michigan wrongly denied Medicaid to Marie Noon, a patient with adult-onset Still’s disease, after the state’s eligibility system failed to register her disability and used the wrong income formula.

• Advocates say similar problems have surfaced in Tennessee, Texas, and Michigan, including cases in which disabled enrollees were routed into limited-benefit programs instead of full Medicaid coverage.

• Deloitte, which has held Michigan Medicaid system contracts since 2006 and works in at least 25 states, said it found no routine system anomaly causing denials and noted states own the systems and set specifications.

Why it Matters for Care

• For clinicians, eligibility glitches can quickly become medication-access crises: Noon said she paid hundreds out of pocket for prescriptions, cut back visits with her doctor, and risked losing drugs used to prevent stroke, control headaches, and manage fluid retention.

• When disabled patients are misclassified, they may lose comprehensive coverage for therapies, surgeries, follow-up, and chronic disease management even if they remain clinically eligible.

• Administrative denials can translate into delayed care, treatment interruptions, and more emergency or inpatient utilization for medically fragile patients.

Between the Lines

• The new federal law adds major operational pressure to already error-prone state systems, requiring fast programming changes on tight timelines while distinguishing who is exempt from new restrictions, including many disabled people.

• That creates a second-order risk: even when the statute does not directly target disabled enrollees, system overload or flawed logic may still push them into wrongful denials or skimpy plans.

• There is also a governance problem: states rely heavily on private contractors, but accountability can blur when vendors say states control policy and states say they see no systemic issue.

What to Watch

• Implementation deadlines: SNAP restrictions began taking effect in 2025, while major Medicaid provisions begin later this year, generally after the midterm elections.

• Litigation and oversight: a federal judge ruled in 2024 that Tennessee violated federal law and the Constitution in a disability-related eligibility case, signaling courts may remain a key check.

• State fixes and audits: watch whether Michigan and other states publish error rates, expand safeguards before limited-benefit enrollment, or seek more contractor changes as complaints mount.
