Description: 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.

Variants
A "variant" is an incident that shares the same causative factors, produces similar harms, and involves the same intelligent systems as a known AI incident. Rather than index variants as entirely separate incidents, we list variations of incidents under the first similar incident submitted to the database. Unlike other submission types to the incident database, variants are not required to have reporting in evidence external to the Incident Database. Learn more from the research paper.
