This Kaiser Family Foundation analysis finds that for workers covered by their employer's health plans, out-of-pocket costs including deductibles and coinsurance have been increasing significantly faster than costs paid by insurers, reflecting a decade-long trend toward slightly less generous coverage.
As the 115th U.S. Congress deliberates the future of the Affordable Care Act, also known as Obamacare, an interactive map from the Kaiser Family Foundation provides estimates of the number of people in each congressional district who enrolled in a 2017 ACA marketplace health plan and the political party of each district’s representative as of October 2017. The analysis also includes maps charting the total number of people enrolled under the ACA Medicaid expansion in 2016 in states that implemented the ACA Medicaid expansion, along with the political parties of their governors and U.S. senators.
A new health care bill recently introduced by a number of senators led by Senators Lindsey Graham and Bill Cassidy would repeal major elements of the Affordable Care Act (ACA), make changes to other ACA provisions, and fundamentally alter federal Medicaid financing. In this brief, we estimate changes in federal funding due to the new block grant program and the Medicaid per enrollee cap on a state-by-state basis under the Graham-Cassidy bill relative to current law. We estimate that the Graham-Cassidy proposal would reduce federal funding for health coverage by $161 billion nationally from 2020-2026, with substantial variation across states.
This map shows the counties at risk of having no insurer on the marketplace (exchange), created by the Affordable Care Act, in 2018, based on a Kaiser Family Foundation analysis of insurer rate filings and news reports.
Note: Congress eliminated the federal tax penalty for not having health insurance, effective January 1, 2019. Along with changes to the health insurance system that guarantee access to coverage to everyone regardless of pre-existing health conditions, the Affordable Care Act includes a requirement that many people be insured or pay a penalty.
This map compares county-level projections of premiums and tax credits for marketplace enrollees under the Affordable Care Act (ACA) in 2020 with estimates for the Better Care Reconciliation Act (BCRA) as unveiled July 20 by Senate Republicans.
This analysis examines a draft amendment to the Senate bill to repeal and replace the Affordable Care Act that would exempt some health plans from market rules, leaving 1.5 million people with pre-existing conditions at risk for higher premiums.
This slideshow compares premiums and tax credits under proposed replacement plans for the Affordable Care Act, including the Senate's Better Care Reconciliation Act and the House-passed American Health Care Act.
This analysis provides estimates of how premiums, after taking into account tax credits, would differ in 2020 under the Senate's Better Care Reconciliation Act (BCRA) vs. the Affordable Care Act (ACA) for people currently enrolled in the federal and state insurance marketplaces.
This interactive includes a map and tables that highlight the increases in health insurance coverage through Medicaid and the Marketplaces as well as the increased federal funding that resulted from the implementation of the ACA.
