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.

Competition Has Increased in the Individual Market But Fallen in Fully Insured Group Markets

Commercial health insurance markets remain highly concentrated across coverage types. However, the individual market, which consists mostly of the ACA Marketplaces, has attracted more insurers and witnessed greater insurer competition across a variety of measures since the implementation of the enhanced premium tax credits in 2021, according to a new Healthy System Tracker analysis.

  • Assessing Americans’ Familiarity With Health Insurance Terms and Concepts

    Poll Finding

    With the approaching launch of the second open enrollment period for the Affordable Care Act’s (ACA) health insurance marketplaces and at a time when open enrollment is also happening for many job-based plans, the Kaiser Family Foundation conducted a nationally representative survey of 1,292 U.S. adults to shed light on Americans’ understanding of basic health insurance terms and concepts, and to identify gaps in awareness that could lead to difficulties for some individuals as they choose new plans or use their health plans.

  • Estimating Federal Payments and Eligibility for Basic Health Programs: An Illustrative Example

    Report

    In some states, policymakers and stakeholders are considering adoption of the Basic Health Program (BHP) option permitted under the Patient Protection and Affordable Care Act (ACA). Federal regulations allow BHP implementation beginning in 2015. Through BHP, consumers with incomes at or below 200 percent of the federal poverty level (FPL) who would otherwise qualify for subsidized qualified health plans (QHPs) offered in health insurance marketplaces instead are offered state-contracting standard health plans that provide coverage no less generous and affordable than what have been provided in the marketplace. To operate BHPs, states receive federal funding equal to 95 percent of the premium tax credits (PTCs) and cost-sharing reductions (CSRs) that BHP enrollees would have received if they had been covered through QHPs. This paper seeks to inform state-level analysts about the characteristics of BHP-eligible people in their state and how to use that information to estimate the approximate federal BHP payment amount per average BHP-eligible resident.

    From Drew Altman
