Palantir's Hidden Role in Medicare AI Coverage Denials Exposed

The Electronic Frontier Foundation (EFF) uncovered records showing that Palantir’s software is embedded within the Wasteful and Inappropriate Service Reduction (WISeR) Model, a Medicare pilot currently active in six states. Application materials from Zyter, a participating technology vendor, confirm that Palantir serves as mission-critical infrastructure for the Centers for Medicare and Medicaid Services (CMS) and multiple private insurers.

A report from the Center for Health and Democracy Education Fund highlights that Palantir provides AI-driven decision-making solutions to industry giants, including Humana, Cigna, and Blue Shield of California. While these companies integrate sophisticated algorithms into their workflows, the specific purposes and data-sharing agreements remain shielded from public oversight. The report warns that because participating vendors receive a cut of the value of denied claims, the system creates a structural incentive to reject care.

Former Cigna executive turned whistleblower Wendell Potter expressed alarm, questioning why these relationships have remained obscured from patients. Critics argue that medical coverage, which determines access to essential care, should not be dictated by profit-driven software designed in secrecy. The Center for Health and Democracy is now calling for the immediate public disclosure of all vendor agreements to clarify the extent to which automated systems influence life-altering health determinations.
