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.

Argentine Court Annuls Embargoes on Retiree After Identity Mix-Up in Child Support Case
Justicia argentina anula embargos a jubilada por cobro indebido de pensión de alimentos a raíz de error de identidad -…
A retiree had her pension wrongly garnished because her name matched that of the defendant in a child support lawsuit. The appeals court confirmed the immediate halt of the deductions and annulled the embargo, ruling it had no legal basis against a third party. The proceedings against the actual defendant were upheld, as the error was limited to the garnishment order sent with incorrect identification.
