How Did the One Big Beautiful Bill Act Change Healthcare Policy?

On July 4, 2025, the One Big Beautiful Bill Act (OBBBA) was signed into law. The legislation, which was passed through the reconciliation process, included sweeping changes to both taxes and spending across the federal budget. The Congressional Budget Office (CBO) projects the legislation will add $3.4 trillion to deficits from 2025 to 2034, making it the most costly reconciliation act in recent history. Including additional interest costs raises the total price tag for the OBBBA to $4.1 trillion.

This piece looks at the changes to healthcare provisions included in the OBBBA, while other entries in the series examine how the legislation affects other spending and taxes.

Healthcare Provisions in the OBBBA Lower Its Cost

Overall, the OBBBA adds significantly to the nation’s debt, but its healthcare provisions lessen that impact by $1.0 trillion from 2025 to 2034. The majority of savings come from net decreases in spending provisions ($819 billion), but there is also a reduction in premium tax credits for Affordable Care Act (ACA) exchange enrollees ($211 billion).

What Healthcare Provisions Generate the Largest Savings?

Below is a summary of the healthcare spending and tax provisions that generate the largest savings in the legislation.

Spending Provisions

On the spending side, Medicaid is the healthcare program impacted the most by the OBBBA. Medicaid spending is growing rapidly. Ten years ago, Medicaid spending totaled $350 billion annually and today it is 77 percent more ($618 billion). To temper those rising costs, lawmakers added multiple provisions in the OBBBA that reduce Medicaid spending. The provisions that will reduce Medicaid spending the most are related to eligibility requirements — the largest being a community engagement requirement ($317 billion), often referred to as a work requirement. The legislation requires states to implement community engagement requirements for adults who became eligible for Medicaid under the ACA or reside in a state with a Medicaid waiver to cover a similar population. Generally speaking, those changes mean that able-bodied adults ages 19–64 without dependents younger than age 14 must be working, studying, volunteering, or participating in job training for 80 hours per month in order to be eligible to receive Medicaid. There are exemptions for parents of dependent children age 13 or younger in addition to those who are medically frail.

Other provisions related to Medicaid eligibility include more frequent eligibility redeterminations (meaning Medicaid recipients will need to prove they are eligible to receive Medicaid more often) ($58 billion), in addition to delaying the implementation of Biden administration rules that would have made enrollment easier for dually eligible Medicare and Medicaid beneficiaries and the Children’s Health Insurance Program (CHIP) ($120 billion).

The OBBBA also generates meaningful savings by making changes to state provider taxes. Currently, states are allowed to use various sources of funding, including general state funds, local government funds, and taxes on healthcare providers (also known as “provider taxes”) to finance the non-federal share of Medicaid spending. States are allowed to tax providers up to 6 percent of their revenue and use that income stream to fund the state share of Medicaid. The reason this results in cost savings is because states have used provider taxes as a way to increase their federal Medicaid match funding, which in turn states can then use to pay providers more with those dollars transferred to the state. The OBBBA now closes that loophole and prohibits states from establishing any new provider taxes or increasing the rates of any existing taxes, except for nursing facilities and intermediate care facilities. This change is projected to reduce federal spending by $183 billion from 2025 to 2034 by limiting states’ ability to leverage provider taxes to access additional federal Medicaid “match” funding.

The OBBBA will reduce spending by another $149 billion over the decade by revising state directed payments, which are payments to providers facilitated by Medicaid managed care organizations. These types of payments are typically used to support providers with a large base of Medicaid patients to make up for the difference between Medicaid reimbursement rates and what those providers argue is their actual cost of care. The OBBBA will now cap state directed payments for inpatient hospital and nursing facility services at 100 percent of the total published Medicare payment rate for states that have adopted Medicaid expansion and 110 percent for states that have not adopted the expansion.

As the legislation was debated, many lawmakers and healthcare experts expressed concerns that the restrictions on Medicaid eligibility and financing changes would present challenges to rural healthcare systems. In an attempt to address those concerns, Congress added $47 billion for a Rural Health Transformation Program to help rural healthcare systems face challenges such as limited access to healthcare providers and financial instability as a result of the OBBBA.

Tax Provisions

In addition to spending cuts, the OBBBA pares back some healthcare-related tax expenditures, which are projected to reduce the deficit by $211 billion from 2025 to 2034. Most of the savings stem from changes to premium tax credits established in the ACA, which cost the federal government $122 billion in 2024. The premium tax credit is a subsidy that reduces a household’s premium for the purchase of an ACA exchange plan. Eligibility clauses in the OBBBA will reduce the deficit by $124 billion by restricting access of the ACA premium tax credits only to U.S. citizens and lawful residents. Before the OBBBA, lawfully present immigrants with incomes under 100 percent of the federal poverty level ($15,650 for a single-person household in 2025) were also eligible for the subsidized marketplace coverage. Now, the OBBBA only allows subsidized marketplace coverage for lawfully present immigrants who are lawful permanent residents, or “green card” holders, regardless of their income level. Certain Cuban and Haitian immigrants, as well as individuals under Compacts of Free Association, remain eligible. Additional eligibility provisions require that exchanges verify eligibility for the premium tax credits before enrollment ($37 billion) and eliminate the year-round enrollment opportunity for people with incomes up to 150 percent of the federal poverty level ($39 billion).

Though not a budgetary saver, the OBBBA also expands eligibility for Health Savings Accounts (HSA) by qualifying those enrolled in bronze and catastrophic health plans. It also permits HSA contributions while participating in direct primary care service arrangements and permanently allows high-deductible health plans to cover telehealth services and other remote care services before patients meet the deductible. In total, those HSA-related provisions will cost the federal government $11 billion from 2025 to 2034.

How Will the OBBBA Affect Insurance Enrollment?

Because many provisions in the OBBBA affect eligibility for health insurance programs, enrollment in the programs will likely be impacted according to the CBO. As of 2024, 8.0 percent of the population, or 27.1 million people, had no health insurance. The CBO estimates that 10.0 million additional people will become uninsured in 2034 because of provisions in the OBBBA. Most of the projected change in the uninsured population in 2034 will result from Medicaid policies (7.5 million people) and policies related to the health insurance marketplaces (2.1 million). The remaining estimate of 0.4 million uninsured people comes from the provision that would impact people dually eligible for Medicaid and Medicare in addition to interactions among policies.

Conclusion

In its totality, the OBBBA considerably worsened the country’s fiscal outlook as it will add $4.1 trillion to the debt over the next decade. The OBBBA attempts to address some fiscal damage through changes to healthcare provisions, largely in Medicaid, but the law’s costs still far outweigh its savings. Looking ahead, healthcare continues to be a significant driver of America’s unsustainable national debt, and there is much more to be done to advance overall system efficiency, find savings and improve clinical outcomes for patients.
