  • 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.

  • How the Elections Could Put the Brakes on Anti-ACA Plans

    From Drew Altman

    In this Axios column, Drew Altman examines the role of health care in Virginia's elections and the referendum on Medicaid expansion in Maine.

  • 2018 Renewal Notices – What Marketplace Consumers Need to Know

    Issue Brief

    As Open Enrollment for 2018 coverage gets underway, consumers who have health coverage through the Affordable Care Act (ACA) Marketplace are again receiving renewal notices from their health insurers. Though the insurer renewal notices this year are based on the same model notice required in the past, this year for many consumers, it may be causing significant – and misleading – sticker shock. That is because renewal notices sent by insurers are required to inform consumers what their 2018 monthly premium will be, assuming they receive the same amount of advanced premium tax credit (APTC) next year that they did in 2017. Insurer renewal notices have been required to present information this way since 2014.

  • Kaiser Health Tracking Poll – November 2017: The Role of Health Care in the Republican Tax Plan

    Feature

    As Republicans in Congress continue efforts to pass tax reform, the November Kaiser Health Tracking Poll examines views of the plans and how they relate to health care issues. Overall, reforming the tax code is seen as a “top priority” for President Trump and Congress by about three in ten (28 percent), falling well-behind several health care issues such as reauthorizing funding for the State Children’s Health Insurance Program (CHIP) (62 percent) and stabilizing the ACA marketplaces (48 percent). In addition, the majority of the public (55 percent) support the idea of eliminating the requirement for all Americans to have health insurance or else pay a fine as part of the Republican tax plan, however views vary party. In contrast, the majority of the public (68 percent), including majorities across parties, oppose eliminating the tax deduction for individuals who have high health care costs. The poll also takes an early look at the public’s views of the potential consequence of Congress not passing tax reform or repealing the ACA before the 2018 midterms.
