Stimulus Bill Expands Obamacare Tax Credits And Subsidizes COBRA Philadelphia Inquirer (PA) Mar. 9—The federal stimulus package could extend health insurance or reduce the cost of insurance to millions of Americans by expanding Affordable Care Act tax credits and subsidizing COBRA coverage. Despite unprecedented job losses during the coronavirus pandemic, the number of people who are uninsured has not increased dramatically — largely due to Affordable Care Act protections. Medicaid enrollment has soared, especially in states that expanded eligibility under the health-care law. People who earn too much to qualify for the publicly funded health program have turned to ACA-created marketplaces, where the vast majority qualify for a reduced-cost premium.
