The statutes governing Medicaid and CHIP—Titles XIX and XXI of the Social Security Act (the Act)—have evolved in the years since their enactment and can be challenging to navigate. MACPAC has annotated the Medicaid and CHIP statutes to provide an informal resource that we hope will assist users in identifying and understanding selected provisions.
MACPAC’s annotations are overlaid on the March 1, 2018 compilations of Titles XIX and XXI of the Act published by the Office of the House Legislative Counsel, the most up-to-date versions available at the time. The annotations do not reflect statutory changes made after March 1, 2018, including changes by the SUPPORT for Patients and Communities Act (P.L. 115-271), which became law on October 24, 2018. Updated compilations of Title XIX and Title XXI are published by the Office of the House Legislative Counsel.
MACPAC’s annotations are neither a formal legal opinion nor an official interpretation of the law and should not be construed as such. For assistance in identifying specific Medicaid provisions in statute, regulations, and state plans, please refer to the MACPAC Reference Guide to Federal Medicaid Statute and Regulations.
