A joint resolution providing for congressional disapproval under chapter 8 of title 5, United States Code, of the rule submitted by the Centers for Medicare & Medicaid Services of the Department of Health and Human Services relating to "Medicare Program; Implementation of Prior Authorization for Select Services for the Wasteful and Inappropriate Services Reduction (WISeR) Model".
Sponsor Ron Wyden (D). Original cosponsor. 21 cosponsors. S.J.Res. 198 on Congress.gov(opens in a new tab)
Introduced
This joint resolution prohibits the Centers for Medicare & Medicaid Services (CMS) from testing a new Medicare payment model in certain states that involves a prior authorization process and the use of enhanced technology by third-party contractors to determine whether certain claims should be paid.
Specifically, the joint resolution nullifies a notice issued by the CMS on July 1, 2025, titled Medicare Program; Implementation of Prior Authorization for Select Services for the Wasteful and Inappropriate Services Reduction (WISeR) Model. (On May 12, 2026, the Government Accountability Office issued a letter of opinion stating that this notice constituted an agency rule and is therefore subject to the Congressional Review Act.)
The CMS selected six states to participate in this model over a six-year period: New Jersey, Ohio, Oklahoma, Texas, Arizona, and Washington. Under the model, contracted companies must process prior authorization requests (i.e., requests for coverage determinations before a service is furnished) for certain services using enhanced technology (e.g., artificial intelligence). Contracted companies are paid based on the share of resulting savings. The CMS aims to test the model's ability to produce accurate results while streamlining the prior authorization process for Medicare claims. The model is based in part on similar processes used for Medicare Advantage claims.
CMS began implementing the model on January 1, 2026. This joint resolution prohibits the CMS from continuing to do so.

Green Ribbon Act of 2026
This bill provides statutory authority for and expands the Department of Education’s (ED’s) Green Ribbon Schools program. (This program was established in 2011 to recognize early learning centers, schools, districts, and postsecondary institutions for excellence in reducing environmental impact, increasing health and wellness, and providing sustainability education.)
In conducting the Green Ribbon Schools program, ED must (1) reserve funding for the Department of the Interior to carry out activities with respect to schools operated or funded by the Bureau of Indian Education; (2) award grants to state educational agencies for the purpose of supporting and engaging eligible entities as green schools; and (3) provide an honorarium to each award winner, subject to appropriations.
The bill directs the Institute of Museum and Library Services to establish an award program for nonformal learning institutions (e.g., libraries, museums, and zoos) that is modeled on ED’s program.
The bill also establishes within ED the Office of School Infrastructure and Sustainability.

Accelerating Access to Critical Therapies for ALS Reauthorization Act of 2026
This bill reauthorizes through FY2031 and revises programs that support research and development of drugs and other therapies to address amyotrophic lateral sclerosis (also known as ALS or Lou Gehrig's disease) and other neurodegenerative diseases.
The bill reauthorizes
• grants from the National Institutes of Health (NIH) for scientific research on investigational drugs to prevent or treat ALS for individuals not otherwise eligible for clinical trials,
• grants from the Food and Drug Administration (FDA) for research and development of therapies to prevent and treat ALS and other neurodegenerative diseases, and
• a Public-Private Partnership including the FDA and NIH that supports development and regulatory review of treatments for neurodegenerative diseases.
Also, the bill revises the NIH grants to require (1) the NIH, in considering grant renewal, to assess available information on the safety and efficacy of the investigational drugs; (2) grantees to promptly report available safety data from ongoing clinical trials; and (3) the NIH to determine the timeframe for enrollment in clinical trials for the investigational drugs.
Additionally, every five years, the FDA must publish a plan describing actions it will take over a five-year period to foster development of safe and effective drugs, and facilitate access to investigational drugs, for ALS and other rare neurodegenerative diseases. Each plan must include the FDA's previous actions and recommendations for improvements.
Finally, the Government Accountability Office and the Department of Health and Human Services must report on the impacts of these grants.

Latonya Reeves Freedom Act of 2026
This bill prohibits government entities and insurance providers from denying community-based services to individuals with disabilities that require long-term service or support that would enable such individuals to live in the community and lead an independent life.
Specifically, these entities may not discriminate against such individuals in the provision of community-based services by such actions as imposing prohibited eligibility criteria, cost caps, or waiting lists or failing to provide a specific community-based service. Additionally, community-based services must be offered to individuals with such disabilities prior to institutionalization. Institutionalized individuals must be notified regularly of community-based alternatives.
The bill requires the Department of Justice to issue regulations requiring government entities and insurance providers to offer community-based long-term services to individuals with such disabilities who would otherwise qualify for institutional placement. Government entities must ensure sufficient availability of affordable, accessible, and integrated housing that is not a disability-specific residential setting or a setting where services are tied to tenancy.
Regulations shall also (1) require government entities and insurance providers to perform self-evaluation on current services, policies, and practices and concerning compliance with requirements of this bill; and (2) require government entities to submit a transition plan.
The bill allows civil actions by individuals subjected to, or about to be subjected to, a violation of its requirements.
