States are paying contractors such as Deloitte, Accenture, and Optum millions of dollars to help them comply with the One Big Beautiful Bill Act — a law that will strip safety-net health and food benefits from millions. State governments rely on such companies to design and operate computer systems that assess whether low-income people qualify for Medicaid or food aid through the Supplemental Nutrition Assistance Program, commonly known as food stamps. Those state systems have a history of errors that can cut off benefits to eligible people, a KFF Health News investigation showed. States are now racing to update their eligibility systems to adhere to President Donald Trump’s sweeping tax-and-spending law. The changes will add red tape and restrictions. They are coming at a steep price ― both in the cost to taxpayers and coverage losses ― according to state documents obtained by KFF Health News and interviews. The documents show government agencies will spend millions to save considerably more by removing people from health benefits. While states sign eligibility system contracts with companies and work with them to manage updates, the federal government foots most of the bill. The law’s Medicaid policies will cause 7.5 million people to become uninsured by 2034, according to the nonpartisan Congressional Budget Office. Roughly 2.4 million people will lose access to monthly cash assistance for food, including those with children. In five states alone, company estimates developed for state officials and reviewed by KFF Health News show that changes will cost at least $45.6 million combined. The law requires most states to tie Medicaid coverage for some adults to having a job, and imposes other restrictions that will make it harder for people with low incomes to stay enrolled. SNAP restrictions began to take effect in 2025. Major Medicaid provisions begin later this year. Documents prepared by consulting company Deloitte estimate that a pair of computer system changes for Medicaid work requirements in Wisconsin will cost nearly $6 million. Two other changes related to the state’s SNAP program will cost an additional $4.2 million, according to the documents, which Deloitte drafted for the Wisconsin Department of Health Services. In Iowa, changes to its Medicaid system are expected to cost at least $20 million, according to an estimate prepared by Accenture, a consulting company that operates the state’s eligibility system. Optum — which operates the platform Vermont residents use for Medicaid and marketplace health plans under the Affordable Care Act — estimated that it could cost roughly $1.8 million to evaluate and incorporate new health coverage restrictions. Initial changes in Kentucky, which has had a contract with Deloitte since 2012, have cost the state $1.6 million. And in Illinois, Deloitte estimated modifications will cost at least $12 million.
