Medicare AI Prior Auth Experiment Exposed

Everyone called WISeR a Medicare efficiency win. The records say otherwise. 🚨

This week the Electronic Frontier Foundation dropped approximately 1,000 pages of internal CMS documents showing what is actually happening inside Medicare’s AI prior authorization experiment.

The findings are damning.

According to EFF, the documents show that WISeR, the Wasteful and Inappropriate Service Reduction model, has resulted in widespread delays and denials of care, operational chaos, and reports of patient harm.

Let that sink in. This is not advocacy spin. These are CMS’s own contracts, internal status reports, and provider complaints, obtained through federal litigation.

Here is what the fetched records reveal:

🔹 CMS launched WISeR in January 2026, subjecting seniors in six states to AI-driven prior authorization decisions
🔹 Private companies contracted by CMS evaluate the requests using AI
🔹 Medical providers must request permission before delivering certain treatments if they want assurance that Medicare will cover them
🔹 Providers reported improper denials, administrative friction, and lengthy delays that left patients waiting in pain

The structural problem here is not a bug. It is the design.

According to EFF, the WISeR program creates a financial incentive for vendors to deny care, because they are paid for averted expenditures. You get paid more when you say no. That is not a neutral algorithm. That is a business model baked into a federal healthcare program.

CMS says a qualified human clinician must review all denials. That sounds like a safeguard. But research cited in the EFF report shows that AI-generated recommendations often influence human decisions. A clinician rubber-stamping an AI denial is not independent review.

This is the part most people are missing.

The debate about AI in healthcare has focused on whether the technology works. The WISeR story shifts the question. It is not just about accuracy. It is about incentive design. Who built the model, who pays the vendor, and what behavior does the contract reward?

When the answer to that last question is denials, patients suffer.

I have spent years working on early detection for the patients who are hardest to reach. I know what it means when someone gets delayed at the point of care. It is not an administrative inconvenience. It is a window that closes.

The government running a six-state AI prior authorization experiment on Medicare beneficiaries, with vendors financially incentivized to deny care, while releasing almost no public information about it, should alarm everyone in this industry.

EFF had to sue to get these records. That alone tells you something about how this program was designed to operate.

Transparency is not optional when seniors are the test subjects. And accountability cannot wait until the six-year pilot concludes.
