Cigna uses algorithm to deny medical claims without doctor review
Cigna, one of the largest health insurers, used an algorithm called PXDX to automatically deny medical claims. The system flagged mismatches between diagnoses and procedures, and company doctors signed off on denials in batches without reviewing patient files. One patient, Nick van Terheyden, was denied coverage for a $350 vitamin D test that his doctor had ordered. Former employees said the system saved Cigna billions of dollars but left patients with unexpected bills.

The NAACP, represented by the Southern Environmental Law Center and Earthjustice, sued xAI and its subsidiary MZX Tech, alleging it ran dozens of methane gas turbines in Southaven, Mississippi, without a Clean Air Act permit to power its Colossus 2 AI data centre.
