AI Medicare Pilot Fails as Vendors Profit from Denials, Delaying Senior Care

Key points

• WISeR, the Wasteful and Inappropriate Service Reduction model, launched in January 2026 in New Jersey, Ohio, Oklahoma, Texas, Arizona, and Washington.
• The program requires prior authorization for services like nerve stimulation, spinal fusions, and skin substitutes, which previously did not require such approval in traditional Medicare.
• Vendors are financially incentivized to deny care, receiving 25% of the regional benchmark cost for every denied request, creating a direct conflict of interest.
• Technical issues led to delays of up to 83 days for decisions, with one vendor, Innovaccer, initially auto-approving all requests to avoid backlogs.
• The Government Accountability Office found the program was set up without proper procedure, questioning its legality.
• The administration plans to expand WISeR to cover oncology, cardiac catheterization, and advanced imaging in the coming years.

Background

This development follows a broader push by the Trump administration to accelerate AI adoption, including the creation of an 'AI Force' and the appointment of an AI Czar in September 2026. While the administration has framed AI as an economic engine and dismissed safety concerns as a 'hoax,' the WISeR pilot represents a direct application of these policies to critical healthcare infrastructure. Previous archive coverage noted the administration's rejection of global AI oversight and its emphasis on US dominance in AI innovation, contrasting sharply with the current regulatory failures in the Medicare sector.

How outlets are covering it

Ars Technica and the Medicare Rights Center emphasize the human cost of the program, citing patient suffering and provider frustration. Ars highlights specific vendor failures, such as Virtix denying 53% of requests and Innovaccer's initial auto-approval strategy. The Medicare Rights Center argues the model's design is fundamentally flawed due to the financial incentive to deny care. POLITICO Pro notes that while Democrats are pushing for transparency, some Republicans are also concerned about the model's impact, though the party has generally avoided criticizing it due to its anti-fraud framing. Sen. Patty Murray (D-Wash.) and Rep. Suzan DelBene (D-Wash.) have led efforts to force document releases, which Republicans voted down. CMS nominee Chris Klomp defended the program, claiming penalties for inappropriate denials are significant, but Ars Technica points out that these penalties are minimal compared to the profits from denials.

Why it matters

The WISeR pilot sets a precedent for using AI in critical healthcare decisions, potentially affecting millions of seniors. The financial incentives built into the model create a systemic bias against patient care, which could lead to widespread harm if expanded. The lack of transparency and the failure of technical systems raise serious questions about the safety and efficacy of AI in government-managed healthcare programs. As the administration plans to expand the model to high-risk areas like oncology, the potential for patient harm increases significantly.

What to watch

The administration plans to expand WISeR to cover oncology, cardiac care, and advanced imaging in the coming years. Lawmakers are expected to continue pushing for transparency and potential legislative action to halt or modify the program. The Center for Medicare and Medicaid Innovation is set to release a report card on vendor performance, which may influence future policy decisions. The EFF litigation may result in further document releases, potentially revealing more details about the program's impact and the administration's response.
