States Step In to Make Obamacare Plans More Affordable After Subsidy Expiration

In the wake of the federal tax credits for Obamacare plans expiring at the end of 2024, monthly premiums have spiked for millions, potentially doubling or tripling in cost. However, ten Democratic-leaning states—California, Colorado, Connecticut, Maryland, Massachusetts, New Jersey, New Mexico, New York, Vermont, and Washington—are using state funds to help residents afford coverage through their marketplaces. This assistance, some predating the federal cutoff, is saving enrollees hundreds of dollars monthly and stabilizing enrollment in key areas.

The Impact of Expired Federal Subsidies on Obamacare Enrollment

The enhanced federal subsidies, introduced via the American Rescue Plan Act in 2021 and extended through 2025 by the Inflation Reduction Act, were a temporary pandemic measure. They boosted Affordable Care Act (ACA) marketplace enrollment from 11.4 million in 2020 to 24.3 million last year, available to all regardless of income, with extra aid zeroing out premiums for some low-income households.

Congress allowed these subsidies to lapse on December 31, 2024. Federal data shows marketplace enrollment dropped by about 1.2 million by the end of last month compared to the prior year. The Congressional Budget Office projected 4.2 million more uninsured by 2034 without intervention.

Compounding the issue are broader cost drivers, including labor shortages and soaring prescription drug prices. Notably, demand for GLP-1 drugs like Ozempic and Wegovy—used for diabetes and weight management—has driven up overall health care expenses, indirectly inflating Obamacare premiums as insurers adjust for pharmacy benefit costs.

Understanding GLP-1 Drugs' Role in Rising Premiums

GLP-1 receptor agonists such as semaglutide (Ozempic, Wegovy) mimic gut hormones to regulate blood sugar, slow gastric emptying, and promote satiety, aiding metabolic health. Their popularity for weight loss has exploded, with U.S. prescriptions surpassing 15 million monthly in recent peaks. This surge strains insurance formularies, as high list prices (often $1,000+ monthly before rebates) contribute to medical loss ratio pressures, leading to premium hikes across plans, including Obamacare marketplaces.

Patients on these therapies should discuss formulary coverage with providers, as state-based subsidies can help offset out-of-pocket jumps post-subsidy expiration.

State-Run Marketplaces: The Key to Local Subsidies

Under the ACA, states can use HealthCare.gov or run their own exchanges. Only the 21 states plus D.C. with state-run marketplaces can offer state-funded credits. At least ten are doing so to cushion the federal gap.

"Many of the people who buy Obamacare plans have fallen between the cracks of the health care system," said Matt McGough, policy analyst at KFF. "They might not work a job or work enough hours to be eligible for health benefits. They are too young for Medicare. They make too much for Medicaid, and they really have no other option but to go to the marketplace."

McGough warns that without aid, healthier individuals may drop coverage, leaving sicker enrollees and spiraling premiums—a "death spiral" states aim to prevent.

New Mexico: A Full Replacement Model

New Mexico stands out, fully replacing federal subsidies for all 82,400 marketplace enrollees through June 30 via its Health Care Affordability Fund. Gov. Michelle Lujan Grisham allocated an extra $17.3 million this year. Funded by a 3.75% surtax on insurers (expected to yield $165 million annually), the fund currently directs 55% to affordability, with plans to rise to 100% by 2028.

Result: Enrollment up 18% this year, bucking national trends. "We feel really great about having come together to really focus on these affordability challenges for New Mexicans," said Kari Armijo, cabinet secretary for the New Mexico Health Care Authority.

Critics like Paul Gessing of the Rio Grande Foundation argue it's unsustainable, urging provider recruitment and malpractice reform instead. Armijo concedes long-term strains as costs rise.

California's Targeted Approach

California's 1.9 million enrollees saw a 32% enrollment drop. The state spends $190 million to fully replace subsidies for those up to 150% federal poverty level (FPL; $23,940 individual) and partially up to 165% FPL, aiding 390,000. Funded by its Health Care Affordability Reserve Fund via general revenue and tax penalties.

"Any amount of money that you can put into affordability is meaningful," said Jessica Altman, executive director of California's marketplace.

Colorado's New Premium Assistance

Colorado approved $110 million in an August 2025 special session for its Colorado Premium Assistance program, targeting 133%-400% FPL ($43,890-$132,000 for family of four). Enrollment cancellations doubled during open enrollment.

"It is clear that this is a value for Coloradans," said Nina Schwartz, chief policy officer for Colorado's marketplace.

Other States' Efforts

• Connecticut: $115 million in 2026 for up to 200% FPL.
• Massachusetts: $250 million enhances subsidies for under 400% FPL, stabilizing 270,000 enrollees; 25,000 cancellations by early January.
• Maryland: Full aid under 200% FPL, partial to 400% FPL.
• New Jersey, New York, Vermont, Washington: Varied aid; New York up to 400% FPL since last year; Washington under 250% FPL since 2023.

What This Means for Patients and Enrollees

Only New Mexico fully fills the gap for all incomes; others prioritize low-to-moderate earners. Savings can reach hundreds monthly, but budget pressures loom with health costs rising—partly from GLP-1 demand.

Practical Guidance: Checking Eligibility and Next Steps

1. Visit your state's marketplace site (e.g., New Mexico's BeWellnm, California's Covered California).
2. Enter income details during open enrollment or special periods.
3. Discuss with advisors: Compare plans covering needed meds like Ozempic.
4. Track costs: Tools like symptom and medication trackers can help monitor GLP-1 adherence amid affordability shifts.

Residents in federal marketplace states lack this option, facing full premium hikes.

Challenges and Future Outlook

States face deficits (e.g., California's potential $22 billion by 2027) and sustainability questions. D.C., Maryland, and Texas saw gains, but most report drops. Broader reforms—like addressing GLP-1 costs via negotiation or generics—could ease pressures.

Key Takeaways

• Ten states are partially or fully replacing expired federal Obamacare subsidies, aiding hundreds of thousands.
• New Mexico leads with universal replacement, boosting enrollment 18%.
• Rising GLP-1 drug costs like Ozempic contribute to premium pressures.
• Check your state's marketplace for eligibility to avoid coverage gaps.
• Enrollment nationally down 1.2 million; states aim to prevent worse uninsured spikes.

Conclusion

State initiatives demonstrate commitment to ACA accessibility post-federal aid lapse, but long-term viability hinges on cost controls—including for high-demand therapies like GLP-1s. Patients should explore state aid promptly, consult providers on plan choices, and stay informed on enrollment windows for uninterrupted care.
