Senate Decision on AI in Medicare

The Senate has voted to reject a resolution aimed at overturning a Centers for Medicare & Medicaid Services (CMS) pilot program. This program utilizes artificial intelligence (AI) to review specific Medicare treatment requests. While there are concerns that AI might allow private contractors to delay or deny necessary medical care for seniors, the initiative is defended by the Trump administration and CMS as a way to reduce waste, fraud, and unnecessary treatments in Medicare.

CMS Administrator Dr. Mehmet Oz stated, “CMS is committed to crushing fraud, waste and abuse, and the WISeR Model will help root out waste in Original Medicare.” The program is said to combine technology with experienced clinicians to streamline the prior authorization process and protect beneficiaries from unnecessary procedures.

The Senate vote was divided along party lines. 46 Democrats supported repealing the CMS AI pilot, while 50 Republicans voted to maintain it. Four senators abstained: Republicans Bill Hagerty, Mitch McConnell, Roger Wicker, and Democrat Chris Murphy.

National Debate Over AI in Healthcare

There is growing concern about AI’s role in healthcare decisions. Critics suggest the WISeR model, a prior authorization system, might slow access to care for seniors who opted for original Medicare to avoid preapproval requirements common in Medicare Advantage and private insurance plans.

If the pilot expands nationally, millions could face additional approval layers before receiving treatments. Concerns highlight AI’s potential impact on care access.

Senators Who Opposed the Repeal

The senators who voted against the resolution to remove the WISeR program are:

• Alan Armstrong (Oklahoma)
• Jim Banks (Indiana)
• John Barrasso (Wyoming)
• Marsha Blackburn (Tennessee)
• John Boozman (Arkansas)
• And others from 44 more states.

The WISeR model, launched in January, operates in Arizona, New Jersey, Ohio, Oklahoma, Texas, and Washington. It subjects certain services prone to fraud or unnecessary spending to prior authorization before Medicare payment approval. CMS uses AI-assisted technology as part of its review process.

Michael Ryan, finance expert and founder of MichaelRyanMoney.com, argued, “AI isn’t the danger. But paying an outsider to say no to seniors’ care is.” He pointed out that contractors receive bonuses for denied claims categorized as ‘avoided waste.’

Democratic Leaders Advocate Repeal

Democrats, led by Ron Wyden, Maria Cantwell, Richard Blumenthal, Patty Murray, and Kirsten Gillibrand, expressed concerns that the pilot causes care delays.

Patty Murray stated, “The WISeR model effectively cuts Medicare by delaying and denying claims using AI—leading to serious consequences.” She emphasized that prior authorization via AI burdens patients and doctors, making seniors wait longer for care.

A report by Cantwell showed Washington hospitals facing longer authorization times, with procedures taking up to four times longer to receive approval. Wyden commented, “Americans are sick of abusive prior authorization tactics putting healthcare out of reach.”

Resolution’s Journey to the Senate

Momentum for the resolution increased after the Government Accountability Office confirmed WISeR as a rule under the Congressional Review Act (CRA), enabling Congress to overturn it through a disapproval resolution.

Drew Powers, Powers Financial Group founder, stated, “AI in healthcare and especially in preauthorization decisions is concerning. The WISeR Model aims to streamline Medicare and Medicaid claims, but given AI’s infancy, relying on it for critical decisions is perhaps premature.”

CMS argues the model does not alter Medicare coverage rules, requiring licensed clinicians’ input on non-payment decisions. It targets services vulnerable to improper billing or unnecessary use.

Kevin Thompson, CEO of 9i Capital Group, noted, “AI doesn’t eliminate bias; it amplifies existing biases in the data it’s trained on.” He warned that without safeguards, delays and denials might disproportionately impact vulnerable populations.

Outlook After Senate Vote

The Senate’s decision leaves the WISeR model unchanged, letting CMS continue its AI-assisted prior authorization pilot in six states.

Murray, voicing continued opposition, tweeted, “Democrats tried to stop AI in Medicare. Republicans blocked it—believing AI knows better for seniors’ healthcare decisions.”

The program persists in Arizona, New Jersey, Ohio, Oklahoma, Texas, and Washington, where Medicare services need prior authorization or pre-payment review.

Michael Ryan commented, “Medicare can fight waste without turning a sick senior into an AI appeal. This vote shapes Medicare’s future: traditional or an Advantage-like gatekeeping model?”
