The Words Matter Act of 2025 directs targeted amendments across federal law to replace the terms “mental retardation” and “the mentally retarded” with contemporary phrases such as “intellectual disability” or “individuals with intellectual disabilities.” The bill applies by name to a long list of statutory provisions spanning criminal law, health programs (including Medicaid and Medicare‑related authorities), Indian Health Service provisions, nursing‑facility and long‑term care rules, grant programs, and other federal definitions.
Beyond word substitution, the bill requires federal agencies to treat existing regulatory references as if they already used the new phrasing and to annotate any amended regulations to show the former term and the new equivalent. It also includes a rule of construction stating that the Act is not intended to change eligibility, coverage, rights, or compel States to alter their own terminology, seeking to avoid unintended substantive legal effects while modernizing language.
At a Glance
What It Does
The bill systematically amends named federal statutory provisions to replace the phrases “mental retardation” and “the mentally retarded” with “intellectual disability” or similar person‑first language. It instructs agencies how to treat and amend existing regulations and requires an explicit note in any updated regulation that the prior term was replaced.
Who It Affects
Federal agencies that administer health, social‑service, housing, and criminal‑justice programs; state Medicaid and long‑term care administrators who use federal statutory terms; courts and defense counsel in capital‑punishment contexts where 18 U.S.C. 3596(c) appears; and disability advocates and service providers who rely on federal program definitions and materials.
Why It Matters
The change reduces stigma in the federal code and seeks consistency in disability terminology across major program statutes. Because the amendments touch core program statutes (Medicaid, Social Security Act titles, and criminal statutes), the bill raises operational questions for agencies about updating regulations, forms, guidance, and IT systems without altering substantive legal rights or eligibility.

What This Bill Actually Does
This bill is a focused language modernization: it goes through a long list of federal statutes and swaps outdated disability terms for contemporary, person‑centered language—primarily replacing “mental retardation” with “intellectual disability” and “the mentally retarded” with “individuals with intellectual disabilities.” The statutory changes are not free‑standing new programs or funding; they are amendment lines inserted into existing provisions of titles such as the Social Security Act, the National Housing Act, the Indian Health Care Improvement Act, the Public Health Service Act, the Omnibus Crime Control and Safe Streets Act, and others.
Mechanically, the bill uses a search‑and‑replace approach within specified statutory subsections and headings; some amendments are to section headings or program titles, while others alter eligibility language within benefit definitions, facility descriptions, and criminal‑law triggers. The bill expressly covers a variety of contexts—from definitions used for Medicaid intermediate care facilities and nursing home quality standards to the statutory phrase governing competency and intellectual disability at the federal death‑penalty stage—so the single bill updates terminology across programmatic, provider, and criminal‑justice settings.To manage regulatory follow‑through, Section 3 treats existing regulatory references as if they already used the new phrasing for purposes of interpretation and requires agencies, when they actually amend regulations to match the statute, to insert a clear note saying the term was formerly “mental retardation” and is now “intellectual disability.” Section 4 adds a rule of construction clarifying congressional intent that these are terminology changes only—not changes to coverage, eligibility, or definitions—and that States are not compelled to change their laws by this federal textual update.Implementation will therefore be administrative and cross‑agency: legal offices must track thousands of regulatory citations, program offices must update forms, manuals, and IT fields used for eligibility and reporting, and training materials will need revision.
The bill does not create a new federal definition of “intellectual disability”; it generally substitutes the term where “mental retardation” previously appeared, leaving substantive statutory criteria or program thresholds unchanged on their face.
The Five Things You Need to Know
Section 3 instructs agencies to treat existing regulations that use the old term as if they already referenced “intellectual disability” and requires a conspicuous explanatory note when regulations are amended to match the statute.
Section 4 explicitly says the Act is not intended to change program coverage, eligibility, rights, responsibilities, or definitions, and it does not force States to change their terminology in state law.
The bill amends specific federal provisions ranging from 18 U.S.C. 3596(c) (death‑penalty implementation) to numerous Social Security Act sections governing Medicaid and long‑term care facility rules.
Multiple statute headings and program titles are changed (for example, title headings in the Social Security Act and Developmental Disabilities Act), which will require updates to statutory references used in guidance, contracts, and interagency memoranda.
The amendment style is targeted and mechanical—striking and inserting language in dozens of discrete statutory subsections—rather than instituting a single cross‑cutting definitional section for “intellectual disability.”.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Substantive amendment list—statutory word replacements
Section 2 is the operative sweep: it lists the statutes and exact places where the replacement text must occur. Rather than adopting a new unified definition, the bill amends each statutory locale individually—changing program titles, subsection language, and headings. Practically, that means the legislative text itself will show the new phrasing in the United States Code where these fragments are codified, but it does not create one centralized definitional provision to govern all occurrences.
Criminal justice—intellectual disability language for death‑penalty implementation
The bill replaces “is mentally retarded” with “has an intellectual disability” in the statute governing implementation of a federal death sentence. This is a high‑visibility substitution because courtrooms, defense teams, and clemency processes often rely on statutory phrasing when assessing competency or eligibility for execution. Although the rule of construction seeks to avoid substantive change, litigants could still press whether the new term carries different clinical or legal meaning in capital cases.
Health and long‑term care programs—Medicaid, Medicare, and related definitions
The bill updates language across Title XIX and Title XVIII‑related provisions that define intermediate care facilities, nursing‑facility quality standards, and other Medicaid/Medicare references. These are operational amendments: state Medicaid plans, provider agreements, and certification processes reference the statutory text, so agencies and states will need to align manuals, surveys, and electronic fields with the new language while preserving the underlying programmatic criteria.
Tribal health and developmental‑disability programs
Statutory terms in the Indian Health Care Improvement Act and the Developmental Disabilities Assistance Act are changed to contemporary terminology. Because some tribal health programs rely on federal statutory phrasing for grant eligibility and program descriptions, the amendments can affect written grant terms and reporting requirements—requiring updates to grant notices, applications, and program literature used by tribes and tribal organizations.
Regulatory implementation and transitional interpretation
Section 3 provides transitional instructions for agency regulations: until an agency amends the text of a regulation, a regulatory reference to the old term will be treated as referencing the new one, and when agencies do amend regulations they must include explicit language documenting the terminology change. This creates a two‑step implementation path—an immediate interpretive rule to avoid gaps plus a requirement for agencies to produce clear annotations when they perform the actual regulatory edits.
Rule of construction—preserving substantive intent
Section 4 frames congressional intent: the exchanges are meant to be terminological only and not to alter program coverage, eligibility criteria, or compel states to change their own law. This provision is designed to reduce litigation risk and downstream disruption, but it is a statutory instruction rather than a regulatory mechanism—agencies and courts will still interpret how that intent operates in disputes.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Individuals with intellectual disabilities and their advocates — the statute uses contemporary, person‑first language which reduces stigmatizing terminology in federal law and program materials, improving dignity and public discourse.
- Federal program administrators and legal teams — modernized statutory language reduces inconsistencies between federal publications and contemporary clinical terminology, simplifying public communications and outreach.
- Healthcare and long‑term‑care providers — standardized federal phrasing over time will reduce confusion in consumer materials, intake forms, and training modules that reference federal statutes.
Who Bears the Cost
- Federal agencies (HHS, DOJ, HUD, VA, etc.) — must inventory affected regulations, update regulatory text, guidance, forms, IT systems, and public-facing materials, absorbing administrative workload and potential contract costs.
- State Medicaid agencies and providers — while not compelled to change state law, many states will need to update state statutes, plan language, manuals, and electronic eligibility fields to maintain consistent references to federal requirements and reimbursement rules.
- Small nonprofits and community service providers — will need to revise brochures, intake paperwork, and grant applications that replicate federal statutory phrasing; some will bear modest compliance costs and staff time to update documents.
Key Issues
The Core Tension
The bill pits the legitimate objective of removing stigmatizing, outdated terminology against the need for legal stability: modernizing language can improve dignity and clarity, but swapping words across foundational program statutes risks creating interpretive uncertainty about eligibility, procedural rights, and court decisions that hinged on the prior phrasing—forcing agencies and courts to balance humane language reform with preserving settled legal meanings.
The Act’s surface simplicity masks several implementation challenges. First, the bill does not supply a single technical definition of “intellectual disability”; it simply substitutes that phrase wherever the old wording appeared.
In many program contexts statutory eligibility or service thresholds reference clinical criteria (developmental onset, IQ ranges, functional limitations) that courts and agencies have interpreted based on the older language. Without a harmonized definitional crosswalk, litigation may arise over whether existing judicial or administrative interpretations tied to the former term transfer seamlessly to the new wording.
Second, Section 3’s transitional treatment reduces the risk of immediate gaps but forces agencies into a substantial rule‑making and administrative update exercise. Agencies will have to coordinate across legal, programmatic, IT, and public‑affairs offices to change regulations, update thousands of references in guidance and forms, and annotate each amended regulation to display both the former and current terms.
That work is time‑consuming and could create inconsistent interim practices across departments. Finally, although Section 4 says States are not compelled to change terminology, differences between federal statutory text and state statutes or case law may create coordination and compliance frictions—especially for programs like Medicaid where federal and state rules interlock and rely on consistent language for audits, eligibility determinations, and reimbursement.
