Cigna Healthcare

A class action alleges that over a two-month stretch in 2022, Cigna medical directors used a system called PXDX to deny more than 300,000 claims at an average of 1.2 seconds of review each - and a former Cigna physician told ProPublica the process amounted to clicking submit on batches of fifty at a time, taking about ten seconds. The legal theory is precise rather than rhetorical: California law requires a medical-necessity denial to be reviewed by a licensed physician competent to evaluate the specific clinical issue, and the plaintiffs argue a 1.2-second rubber stamp is not a review, which would also breach the plan's own terms requiring a medical director to make the call. Cigna's defense is that PXDX is not AI at all but simple sorting technology that matches procedure codes to diagnosis codes, similar to systems CMS itself uses, and that the vast majority of claims routed through it were paid automatically. A judge let the case proceed in March 2025.
