The MassHealth Proposed Demonstration Extension 2022–2027: Building on Success, Focusing on Equity
Massachusetts administers much of MassHealth through an 1115 Demonstration waiver, approved by the Centers for Medicare and Medicaid Services (CMS), which it has extended several times since it was originally approved in 1995. In December 2021, Massachusetts submitted a request to CMS to extend its Demonstration for another five years.
