No. 003/AI claim denial

Cigna

Codename · PXDX

A federal class action alleges Cigna used an algorithm called PXDX to deny claims in bulk, after ProPublica reported that its doctors denied around 300,000 claims in two months at an average of 1.2 seconds each, without reviewing the records. Cigna calls this a mischaracterisation of its process for speeding up payment of claims for routine, low-cost screenings.
