| The skinny In January 2026, CMS launched the Wasteful and Inappropriate Service Reduction (WISeR) model, introducing prior authorization into traditional Medicare for certain services in selected states. However, this controversial program could face a repeal following an effort led by Congressional Democrats this month. The background The WISeR model seeks to reduce unnecessary, duplicative and low-value care in traditional Medicare via prior authorization and the use of AI. It's currently being tested in Arizona, New Jersey, Ohio, Oklahoma, Texas and Washington, and in partnership with tech vendors Cohere Health, Genzeon Corporation, Humata Health, Innovaccer, Virtix Health and Zyter. The model is controversial for two main reasons, according to Neil Patil, senior fellow and the policy director at the Medicare Policy Initiative at Georgetown’s Center on Health Insurance Reform. While prior authorization can help reduce wasteful care, it can also lead to denials and delays of necessary care. Prior auth can also increase out-of-pocket expenses for beneficiaries. In addition, the fact that the WISeR model leverages AI is worrying as the technology can lead to more denials and worsen health disparities. Fight to repeal As a result, several Congressional Democrats are fighting the implementation of the WISeR model. On May 20, Democrats — including Sen. Ron Wyden (D-Oregon), Rep. Suzan Delbene (D-Washington) and Rep. Greg Landsman (D-Ohio) — introduced a resolution to repeal the WISER model through the Congressional Review Act (CRA). The CRA empowers Congress to review and overturn federal agency rules. The resolution came after the Government Accountability Office found on May 12 that WISeR imposes new prior authorization requirements on some Traditional Medicare providers, meaning it qualifies as a rule that may be subject to congressional review under the CRA. The CRA requires federal agencies to submit rules to Congress before they take effect, and if they fail to do so, Congress may take steps to repeal the rule. Could it be repealed? While repealing the WISeR model has the support of Congressional Democrats, it’s hard to say for sure if it will gain the support of Congressional Republicans and ultimately President Donald Trump, who will need to sign off on it, according to Patil. “Given that this is the Trump administration's own model that they introduced, I would imagine it's pretty unlikely that the president would go ahead and sign on and terminate this model,” he said. “I would imagine that even if this resolution does pass both chambers of Congress, it's likely it would be vetoed by the President. Now, granted, if it passes both chambers with a lot of support, I think it would be pretty difficult for the president to see that and go ahead and veto it.” — By Marissa Plescia |
