Congress blocks Medicare from using AI to deny care

What it does

This bill prohibits the Department of Health and Human Services from implementing the WISeR model—a Medicare pilot program that uses prior authorization (including AI) to identify and reduce wasteful or inappropriate services—and bars the Centers for Medicare & Medicaid Innovation from testing any similar prior-authorization models under traditional Medicare going forward. The bill protects Medicare beneficiaries from having their doctors' treatment decisions delayed or denied by automated systems.

Why we flagged it

The bill's operative mechanism is a straightforward prohibition on a specific payment model and a class of future models. It is a direct restriction on government authority to implement prior authorization in Medicare, framed as consumer protection against AI-driven service denials.

What the text implies

• Blocks not only the named WISeR model but any 'substantially similar' model, creating a broad statutory bar on prior-authorization testing in traditional Medicare—future administrations cannot easily revive such pilots without new legislation.
• Forecloses potential cost-containment strategies: if WISeR or similar models could identify genuinely wasteful services, this bill prevents that data from being collected, potentially raising Medicare spending over time.

Who it affects

Medicare beneficiaries gain protection against AI-driven service denials and delays; doctors retain clinical autonomy without algorithmic interference. The bill removes a mechanism that could restrict access to care, though it also forecloses potential cost savings from identifying genuinely wasteful services.
