There is No Drop-Dead Date for an ACA Tax Credit Extension, But Coverage Losses Will Mount as the Clock Ticks

A discharge petition in the House paves the way for a vote on a three-year extension of the tax credits, which would provide ACA enrollees premium relief whenever it comes. While there is still time to extend the enhanced tax credits, with each passing day, more and more ACA Marketplace enrollees are going to drop their health insurance when faced with eye-popping increases in their premium payments, writes KFF’s Larry Levitt.

  • Approved Changes in Indiana’s Section 1115 Medicaid Waiver Extension

    Issue Brief

    On February 1, 2018, the Centers for Medicare and Medicaid Services (CMS) approved an amended extension of Indiana’s Healthy Indiana Program 2.0 (HIP 2.0) Section 1115 demonstration waiver. Indiana’s waiver initially implemented the ACA’s Medicaid expansion from February, 2015 through January, 2018 by modifying Indiana’s pre-ACA limited coverage expansion waiver (HIP 1.0). Unlike other states that implemented the ACA’s Medicaid expansion through a waiver, Indiana’s demonstration also changes the terms of coverage for non-expansion adults (low-income parents and those eligible for Transitional Medical Assistance, TMA). The February, 2018 extension continues most components of HIP 2.0 and adds some new provisions.

  • Implications of the ACA Medicaid Expansion: A Look at the Data and Evidence

    Issue Brief

    More than four years after the implementation of the Medicaid expansion included in the Affordable Care Act, debate and controversy around the implications of the expansion continue. Despite a large body of research that shows that the Medicaid expansion results in gains in coverage, improvements in access and financial security, and economic benefits for states and providers, some argue that the Medicaid expansion has broadened the program beyond its original intent diverting spending from the “truly needy”, offers poor quality and limited access to providers, and has increased state costs. New proposals allow states to implement policies never approved before including conditioning Medicaid eligibility on work or community engagement. New complex requirements run counter to the post-ACA movement of Medicaid integration with other health programs and streamlined enrollment processes. This brief examines evidence of the effects of the Medicaid expansion and some changes being implemented through waivers. Many of the findings on the effects of expansion cited in this brief are drawn from the 202 studies included in our comprehensive literature review that includes additional citations on coverage, access, and economic effects of the Medicaid expansion.

  • Individual Insurance Market Performance in 2017

    Issue Brief

    This brief examines recently-released annual financial data from 2017 and finds insurers selling individual market plans had their best financially since 2014, when new ACA insurance market rules took effect that guaranteed access to coverage for people with pre-existing conditions. At the same time, recent political and policy changes, including the repeal of the individual mandate penalty as part of tax reform legislation and proposed regulations to expand loosely-regulated short-term insurance plans, cloud plans’ outlook going forward.

  • 2019 Premium Changes on ACA Exchanges

    Issue Brief

    This tracker monitors preliminary 2019 premiums in the Affordable Care Act’s marketplaces as insurers file rate information with state regulators. It shows preliminary premium information in a major city in each available state for the lowest-cost bronze plan and “benchmark” silver plan, which is used to determine the size of the premium tax credits available to low- and moderate-income enrollees. The tracker also shows how those premiums are changing from 2018 and what a 40-year-old enrollee making $30,000 annually would pay before and after available tax credits.
