OB3 Impact - Rising Health Costs and Budget Pressures Ahead for Arizona

As Arizona approaches its next budget cycle, the state is facing a serious shift. The One Big Beautiful Bill (OB3) included major federal cuts to programs that Arizona relies on, particularly in health care. For example, under the law, Arizona’s Medicaid program (Arizona Health Care Cost Containment System, or AHCCCS) stands to lose roughly $1.2 billion over 10 years in rural hospital funding alone. At the same time, national-level estimates show the uninsured rate in Arizona could increase by five or more percentage points because of changes to Medicaid and the expiration of enhanced premium tax credits.
From a budgeting perspective, Arizona may be forced to absorb costs that were previously shared or covered by federal funding, whether in Medicaid eligibility, provider reimbursements, or uncompensated care for the uninsured. If more people lose coverage or delay care because of cost, the state may see higher utilization of emergency services or safety-net care, which often falls back on state or local budgets. The result will be a tighter budget envelope, harder decisions on health-care spending, or trade-offs in other areas (education, infrastructure) to offset the increased burden.
The sticker shock for individuals is already beginning to build as we move toward the November open-enrollment period. Roughly 400,000 Arizonans who use the marketplace rely on premium tax credits, and unless those credits are extended, many will face steep premium increases. Some analysts estimate premium hikes of 80 percent or more in certain cases when subsidies end. That means many Arizonans will walk into open enrollment expecting modest changes, and instead face shockingly higher costs. For a state already dealing with inflation, housing cost pressures, and workforce shortages in health care, such premium increases will complicate affordability, may drive people to drop coverage, and could tilt the risk pool toward higher costs for everyone.
The combination of federal cutbacks and premium increases means that legislative decisions in Arizona will be even more important. How the state chooses to respond, whether through adjustments in eligibility, supplemental state support, outreach to keep coverage, or budget reallocations, will shape how severely these impacts are felt on the ground. The November open-enrollment period will be a critical moment, leaving many Arizonans with difficult decisions (Do I keep my coverage even if the premium jumps? Do I switch plans? Do I drop coverage altogether?) As for the Arizona Legislature, the choice will be whether to mitigate the downstream consequences or risk larger budget and health-system disruptions.
