Common Ground Healthcare Cooperative plans to stop offering marketplace plans in Milwaukee, Kenosha, Racine, Outagamie, Winnebago, Fond du Lac, Sheboygan, Calumet, Dodge, Waushara and Waupaca counties beginning in January. Common Ground has been offering ACA marketplace coverage in eastern Wisconsin since 2014. Enhanced premium tax credits were signed into law during the Biden administration, allowing families previously ineligible for ACA tax credits to become eligible. But the enhanced subsidies are set to expire at the end of the year unless they’re renewed. Beyond plans to hike premiums, some insurance providers are leaving the ACA marketplace altogether.
