Annotated Statutes for Medicaid and CHIP

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 30, 2023 versions of Titles XIX and XXI of the Act published by the Office of the House Legislative Counsel. To the best of our knowledge, these were the most up-to-date versions available when we developed this document. Annotations identify the specific provision referenced (e.g., a subsection or a paragraph) and, to the extent possible, are placed adjacent to it. We provide a list of acronyms and abbreviations used in the annotations and their definitions in Table 1, and a list of public laws we cite in the annotations in Table 2.

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.
