Providing for congressional disapproval under chapter 8 of title 5, United States Code, of the rule submitted by the Centers for Medicare & Medicaid Services relating to "Patient Protection and Affordable Care Act; Marketplace Integrity and Affordability".

HJRES 123 is a congressional disapproval resolution targeting a specific rule by the Centers for Medicare & Medicaid Services (CMS). It seeks to nullify CMS's June 2025 rule titled "Patient Protection and Affordable Care Act; Marketplace Integrity and Affordability," which was published in the Federal Register (90 Fed. Reg. 27074). If passed, the resolution would block this rule from taking effect under procedures outlined in Title 5, U.S. Code. The bill directly affects the CMS regulation governing the Affordable Care Act's health insurance marketplace, not the broader law itself.
