The ACA MarketplaceS

Change in February effectuated enrollment, by state, 2025-2026

How Has ACA Marketplace Enrollment Changed Across States in 2026?

ACA Marketplace enrollment fell this year in every state except New Mexico, which was the only state to fully replace the enhanced premium tax credits that expired last year with a state-funded subsidy, according to a new KFF analysis of effectuated enrollment data. The Marketplace enrollment decline—the first in seven years—follows several years of rapid enrollment growth and coincides with the end of the enhanced federal subsidies.

How Much and Why ACA Marketplace Premiums Are Going Up in 2027

ACA Marketplaces insurers are proposing a median premium increase of 15% in 2027, according to KFF’s updated analysis of 276 insurers with publicly available filings across all 50 states and the District of Columbia. This is the second consecutive year of double-digit premium hikes. Last year’s median nationwide proposed rate change was 18%, and the median finalized rate change was 20%. While this proposed rate change is lower than last year, it represents the second-highest requested rate change since 2018, as premium growth had been relatively flat in this market for several years.

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?

  • Medicaid and Community Health Centers: The Relationship Between Coverage for Adults and Primary Care Capacity in Medically Underserved Communities

    Issue Brief

    Community health centers play an important role in providing care to uninsured and low-income individuals living in medically underserved communities. They rely on many different revenue sources and, over time, Medicaid has become a central source of funding for most health centers. To better understand how Medicaid influences health center practice, this paper compares the strength of health centers in states that have expanded Medicaid coverage for adults to health centers states with more limited…

    The Alliance for Health Reform and the Commonwealth Fund sponsor a July 27 briefing to discuss how states are facing implementation and evaluation deadlines in regards to health insurance exchanges.

  • Health Insurance Market Reforms: Pre-Existing Condition Exclusions

    Fact Sheet

    Insurers pursue multiple strategies to reduce the cost of covering enrollees with pre-existing conditions, or medical conditions and health problems that existed before the individual enrolled in a health plan. One strategy, the pre-existing condition exclusion, allows insurers to refuse to cover any costs associated with care for a pre-existing condition permanently or over a period of time. Beginning January 1, 2014, insurers in the individual and group markets will be prohibited from imposing pre-existing…

  • Quick Take: An Update on the ACA & HIV: Medicaid Health Homes

    Fact Sheet

    We recently wrote about the different ways in which the Affordable Care Act (ACA) changes pathways to health insurance coverage for people with HIV, and chronicled these specifics, as well as several outstanding questions, in a policy brief.  As we noted, among the many provisions of the ACA designed to improve care is a new option available to state Medicaid programs to provide “health homes” for Medicaid enrollees with chronic conditions, with a temporary enhanced…

  • Pulling It Together: Perspectives on State Health Reform

    Perspective

    This Pulling It Together column is the fourth in my new series. All four so far have dealt with different dimensions of health reform. This time I write about one of my favorite topics, the states. As a former head of an umbrella health and social services agency in a big state responsible for about a third of a state budget and workforce, I have a deep appreciation for state government. It's a level of…

  • Uninsured Young Adults: A Profile and Overview of Coverage Options

    Issue Brief

    Young adults, age 19-29, have the highest uninsured rate of any age group. Since 29% of the uninsured are young adults, efforts to decrease the overall number of uninsured must address this population. This brief examines health coverage for young adults, as well as their health status, access to care, and the financial burdens they encounter when paying for care. It also provides an overview of public and private approaches to expand health coverage for…

  • Pulling It Together: The “R” Word Is Back

    Perspective

    Longer ago than I care to admit, I got my start in health policy at M.I.T. when I wrote a book about health care regulation. The book was about a long forgotten attempt to rationalize the health care system through an elaborate health planning program set up in the seventies under the National Health Planning and Resources Development Act. It established a system of federal, state and regional planning bodies to control health care costs by limiting the supply of…

  • Pulling it Together: Implementation

    Perspective

    When I was a graduate student at MIT my adviser Jeffrey Pressman was a great political scientist who had just written the seminal book on program implementation.  It was called, simply enough, Implementation, with a subhead that read: "how great expectations in Washington are dashed" (OK, we political scientists study politics too much and are a little cynical at times).  The book literally created a new subfield in political science focusing on program implementation.  This…
