Did the Affordable Care Act Make Health Care More Affordable?

The expiration of the ACA’s enhanced premium tax credits at the start of 2026, combined with rising insurer premiums, put a spotlight on health care affordability that extends beyond Marketplace enrollees. KFF’s Cynthia Cox examines the ACA’s record and the broader underlying question it raises: what’s a fair price for Americans people to pay for health care?

The ACA MarketplaceS

In Preliminary Rate Filings, ACA Marketplace Insurers Largely Propose Double-Digit Premium Increase For 2027, Following a Steep Climb This Year 

ACA Marketplace insurers are proposing a median premium increase of 14% for 2027— indicating a likely second consecutive year of double-digit increases, according to a new analysis of preliminary rate filings in 16 states and DC. If these increases hold, typical premiums for insurers participating in the ACA Marketplaces would jump by more than one-third between 2025 and 2027.

The Average Marketplace Deductible Grew by About $1,000 Per Person in 2026, With More Enrollees Shifting to Higher-Deductible Plans as Enhanced Tax Credits Expired

The average Affordable Care Act (ACA) Marketplace deductible experienced the steepest increase in history—growing by 37% or over $1,000, from $2,759 in 2025 to $3,786 in 2026 as enhanced premium tax credits expired, according to a new KFF analysis. After the enhanced tax credits ended, many Marketplace shoppers shifted toward lower-premium, higher-deductible plans.

  • ¿Cubren los planes del mercado la atención médica de reasignación de género? ¿Qué cambios han habido en los requisitos de cobertura?

    FAQs

    No necesariamente. La cobertura varía según el estado y el plan. Algunos estados, pero no todos, prohíben que los planes médicos excluyan la cobertura de la atención de afirmación de género. Pero incluso en los estados donde la cobertura es obligatoria, es posible que no todos los servicios de afirmación de género estén cubiertos. Por ejemplo, un plan podría cubrir la terapia hormonal, pero no la depilación láser. En los estados donde no se exige…

  • I am about to turn 65 and go on Medicare, and my income is $125,000. I am not married. I know that people with higher incomes are required to pay higher premiums for Medicare Part B and Part D. To avoid...

    FAQs

    If you are not yet enrolled in Medicare, you can buy health insurance coverage through the Marketplace before you turn 65, and if you have a Marketplace plan, you can choose to renew it after you turn 65. But once you turn 65 and become entitled to Medicare coverage, you cannot buy a new Marketplace plan. This is because insurers are prohibited from selling health insurance coverage that duplicates what you have under Medicare, if…

  • I heard that plans have to cover preventive services without cost sharing. Does this include every preventive service and are there any limitations or exceptions?

    FAQs

    Most health plans, including Marketplace plans, are required to cover a wide range of preventive services and may not impose cost-sharing (such as deductibles, copayments, or co-insurance). The ACA requires private plans to cover services under four broad categories: Evidence-based screenings and counseling Routine immunizations Childhood preventive services Preventive services for women So long as the preventive service is performed by an in-network provider, is not billed separately from the office visit, and is the main…

  • My income is low enough that I qualify for advanced premium tax credits (APTCs), but I have never filed a federal tax return before. Can I still receive APTCs?

    FAQs

    If this is your first time applying for premium tax credits, then yes. There is no requirement to have filed a tax return for any prior year to qualify for premium tax credits. However, because you have never filed a federal tax return, you will likely have to provide additional documentation (such as pay stubs or a work contract) to the Marketplace within 90 days to verify your projected household income for premium tax credits. …

  • What are premium tax credits and how do they work?

    FAQs

    Premium tax credits reduce your premium for most Marketplace plans. The amount of the tax credit you may receive depends on your income and the cost of Marketplace health plans in your area. The Marketplace will determine the expected contribution you are required to pay toward the premium for a mid-range (Silver) benchmark plan. The expected contribution will increase on a sliding scale based on your 2026 income, with more financial assistance for enrollees with…
