Doctors Sound Alarm as Medicare's New AI Reviews Begin
Physicians and hospital leaders say the rollout of Medicare's AI-assisted treatment reviews is already creating risk that medically necessary care will be delayed or denied. The program began on January 1, 2026 in six states and will run for six years, testing technology-assisted prior authorization for a set of outpatient services.
What the program does
Known as the WISeR model, the initiative uses enhanced technologies, including artificial intelligence, to screen prior authorization requests before Medicare pays. CMS says the tools will support reviewers and that final determinations will be made by licensed clinicians. The agency frames the effort as an attempt to curb fraud, waste, and low-value care while speeding decisions. The pilot runs from 2026 through 2031.
Why clinicians are worried
Frontline doctors say automation risks turning nuanced clinical judgment into a checklist. A recent American Medical Association survey found that 61 percent of physicians are concerned that unregulated use of AI is increasing prior authorization denials and harming patients. Many report that prior authorization already causes significant delays and administrative strain in clinics. Physicians warn that even short delays can be critical for vulnerable patients.
Pushback and legal challenges
Hospitals, advocacy groups, and some lawmakers have urged pauses or stricter guardrails, saying the program lacks transparency and clear appeal timelines. A tech policy nonprofit has filed suit seeking internal documents about design, vendor roles, and safeguards, reflecting wider concern about gatekeeping by algorithm-assisted systems. Critics say the program could steer care by mistake rather than improve it.
Early impact and the road ahead
Analysts expect the model's practical effect to be limited in year one because it targets a relatively small group of services, and other payment changes are already altering use of high-growth items like skin substitutes. Still, clinicians emphasize that even modest denial rates can cascade into missed surgeries, delayed diagnostics, and more complex downstream care. Physician groups are calling for faster appeals, transparent scoring, and independent audits before any expansion.
Across clinics the message is steady and plain: technology can help, but without ironclad human oversight and clear accountability, the new review system risks replacing timely care with bureaucratic blockage.
