The Depаrtment оf Heаlth аnd Human Services (HHS) is a federal agency that оversees federal health prоgrams like Medicare and Medicaid. The Secretary of HHS decides that decisions to expand Medicaid made by states pursuant to the Patient Protection and Affordable Care Act (PPACA, aka Obamacare) should be invalidated as a waste of federal funds. Rather than notify Congress, the Secretary decides to propose a new regulation to revoke Medicaid expansions and place state programs in the same position as they were pre-Obamacare. If the regulation, once it goes through the processes mandated by the Administrative Procedures Act, is adopted by HHS, will it be effective in changing the federal statute?
