Senate Faces Vote to Halt AI-Driven Medicare Care Denials

The Senate is scheduled to vote Thursday on a resolution spearheaded by Sen. Ron Wyden (D-Ore.) and supported by a coalition including Sen. Bernie Sanders (I-Vt.). The measure targets the Centers for Medicare and Medicaid Services’ (CMS) Wasteful and Inappropriate Service Reduction (WISeR) model. While CMS maintains the program uses AI and machine learning alongside human oversight to ensure appropriate payments, opponents argue the technology functions primarily as a tool for cost-cutting and care obstruction.

Physicians and advocacy groups fear that even with a human sign-off requirement, AI recommendations will dictate outcomes, mirroring practices already observed in private Medicare Advantage plans. Alex Lawson, executive director of Social Security Works, labeled the project a dangerous experiment. According to recent reports, beneficiaries involved in the pilot program, which launched in January 2026, are already experiencing delays in accessing care that are two to four times longer than standard wait times. Critics contend this shift marks a significant expansion of automated denial systems into the bedrock of traditional Medicare, threatening the standard of care for millions of seniors.
