A pilot program testing the use of artificial intelligence to expand prior authorization decisions in Medicare has providers, politicians and researchers asking questions.

Taking a page from the private insurance industry’s playbook, the Trump administration will launch a program next year to find out how much money an artificial intelligence algorithm could save the federal government by denying care to Medicare patients.
The pilot program, designed to weed out wasteful, “low-value” services, amounts to a federal expansion of an unpopular process called prior authorization, which requires patients or someone on their medical team to seek insurance approval before proceeding with certain procedures, tests, and prescriptions. It will affect Medicare patients, and the doctors and hospitals who care for them, in Arizona, Ohio, Oklahoma, New Jersey, Texas, and Washington, starting Jan. 1 and running through 2031.
The move has raised eyebrows among politicians and policy experts. The traditional version of Medicare, which covers adults 65 and older and some people with disabilities, has mostly eschewed prior authorization. Still, it is widely used by private insurers, especially in the Medicare Advantage market.
And the timing was surprising: The pilot was announced in late June, just days after the Trump administration unveiled a voluntary effort by private health insurers to revamp and reduce their own use of prior authorization, which causes care to be “significantly delayed,” said Dr. Mehmet Oz, administrator of the Centers for Medicare & Medicaid Services.
“It erodes public trust in the health care system,” Oz told the media. “It’s something that we can’t tolerate in this administration.”
But some critics, like Dr. Vinay Rathi, an Ohio State University doctor and policy researcher, have accused the Trump administration of sending mixed messages.
On one hand, the federal government wants to borrow cost-cutting measures used by private insurance, he said. “On the other, it slaps them on the wrist.”
Administration officials are “talking out of both sides of their mouth,” said Rep. Suzan DelBene, a Washington Democrat. “It’s hugely concerning.”
Patients, doctors and other lawmakers have also been critical of what they see as delay-or-deny tactics, which can slow down or block access to care, causing irreparable harm and even death.
“Insurance companies have put it in their mantra that they will take patients’ money and then do their damnedest to deny giving it to the people who deliver care,” said Rep. Greg Murphy, a North Carolina Republican and a urologist. “That goes on in every insurance company boardroom.”
Insurers have long argued that prior authorization reduces fraud and wasteful spending, as well as prevents potential harm. Public displeasure with insurance denials dominated the news in December, when the shooting death of UnitedHealthcare’s CEO led many to anoint his alleged killer as a folk hero.
And the public broadly dislikes the practice: Nearly three-quarters of respondents thought prior authorization was a “major” problem in a July poll published by KFF, a health information nonprofit that includes KFF Health News.
Indeed, Oz said during his June press conference that “violence in the streets” prompted the Trump administration to take on the issue of prior authorization reform in the private insurance industry.
Still, the administration is expanding the use of prior authorization in Medicare. CMS spokesperson Alexx Pons said both initiatives “serve the same goal of protecting patients and Medicare dollars.”
Unanswered questions
The pilot program, WISeR — short for “Wasteful and Inappropriate Service Reduction” — will test the use of an AI algorithm in making prior authorization decisions for some Medicare services, including skin and tissue substitutes, electrical nerve stimulator implants, and knee arthroscopy.
The federal government says such procedures are particularly vulnerable to “fraud, waste, and abuse” and could be held in check by prior authorization.
Other procedures may be added to the list. But services that are inpatient-only, emergency or “would pose a substantial risk to patients if significantly delayed” would not be subject to the AI model’s assessment, according to the federal announcement.
While the use of AI in health insurance isn’t new, Medicare has been slow to adopt the private-sector tools. Medicare has historically used prior authorization in a limited way, with contractors who aren’t incentivized to deny services. But experts who have studied the plan believe the federal pilot could change that.
Pons told KFF Health News that no Medicare request will be denied before being reviewed by a “qualified human clinician,” and that vendors “are prohibited from compensation arrangements tied to denial rates.” While the government says vendors will be rewarded for savings, Pons said multiple safeguards will “remove any incentive to deny medically appropriate care.”
“Shared savings arrangements mean that vendors financially benefit when less care is delivered,” a structure that can create a powerful incentive for companies to deny medically necessary care, said Jennifer Brackeen, senior director of government affairs for the Washington State Hospital Association.
And doctors and policy experts say that’s only one concern.
Rathi said the plan “is not fully fleshed out” and relies on “messy and subjective” measures. The model, he said, ultimately depends on contractors to assess their own results, a choice that makes the results potentially suspect.
“I’m not sure they know, even, how they’re going to figure out whether this is helping or hurting patients,” he said.
Pons said the use of AI in the Medicare pilot will be “subject to strict oversight to ensure transparency, accountability, and alignment with Medicare rules and patient protection.”
