01 · The brief

The bill amends section 310(g) of the Congressional Budget Act of 1974 (2 U.S.C. 641(g)) to explicitly prohibit reconciliation legislation from making changes to the Medicare program (Title XVIII of the Social Security Act) or the Medicaid program (Title XIX of the Social Security Act).

It updates the statutory heading and inserts Medicare and Medicaid into the list of programs that reconciliation recommendations may not alter.

Passage30/100

Technically narrow but institutionally consequential; lack of compromise features and likely opposition to constraining reconciliation reduce chances.

CredibilityPartially aligned

Relative to its intended legislative type, this bill is a concise statutory amendment that clearly identifies and locates the procedural change it seeks to make (prohibiting reconciliation changes to Medicare and Medicaid). It integrates with existing statutory citations but omits detailed definitions, implementation guidance, enforcement mechanisms, and fiscal commentary.

Contention60/100

Progressive values beneficiary protections; conservatives emphasize lost reform tools.
