What changed

Cigna health insurer faces a class-action lawsuit for allegedly using the PXDX ("procedure-to-diagnosis") algorithm to automatically reject over 300,000 patient claims in violation of California law, prompting two members to file the lawsuit seeking damages and a jury trial. Cigna disputes the allegations, claiming the process expedites physician reimbursement and does not result in care denials.
