HHS appeals decision vacating provisions of 2025 ACA marketplace rule

The Department of Health and Human Services (HHS) and the Centers for Medicare & Medicaid Services (CMS) have taken their case to a higher court after a Maryland federal court vacated parts of the 2025 "Marketplace Integrity and Affordability Rule." The plaintiffs, including city governments and various groups, argued against the rule's provisions. This appeal is crucial as it could impact how healthcare marketplaces operate and affect millions of Americans enrolled in ACA plans. The outcome will set a significant precedent for future regulations on healthcare affordability and market integrity.
