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.

Flood of AI-generated error-filled bills increases correction workload for U.S. lawmakers
米議員がAIで作成した「間違いだらけの法案」が殺到し、修正作業の負担が増大 ─ "便利"なはずのAIが抱える「隠れたコスト」 - The Liberty Web
Politico reported that U.S. House members are submitting bills created with generative AI that contain numerous errors. Staff at the Office of the Legislative Counsel say they are spending more time fixing AI-drafted bills than it would take to write them from scratch, as the tools lack the necessary legal nuance and often misrepresent policy intent.

IRS Audit Selection Algorithm Disproportionately Audits Black Taxpayers
A Stanford study found that the IRS's secret audit selection algorithm causes Black taxpayers to be audited at 2.9 to 4.7 times the rate of non-Black taxpayers. The disparity is driven by the algorithm's focus on the likelihood of underreporting rather than the magnitude, and on refundable tax credits like the Earned Income Tax Credit. Single Black men claiming dependents and the EITC are nearly 20 times more likely to be audited than non-Black married couples claiming the same credit. The researchers suggest the IRS could modify its algorithm to reduce racial disparities without sacrificing revenue.

Amazon hid rising injury rates at robotic warehouses
Internal records obtained by Reveal show Amazon misled the public about worker safety, with serious injury rates at its fulfilment centres rising 33% from 2016 to 2019. Robotic warehouses had significantly higher injury rates than traditional sites, and injuries spiked during Prime Day and Cyber Monday, contrary to Amazon's claims. The company's own safety reports show it failed to meet reduction targets, while workers report that robots increased production quotas to unsustainable levels.

USPS algorithm RRECS causes pay cuts for two-thirds of rural mail carriers
The United States Postal Service (USPS) implemented a new algorithm, RRECS, to evaluate rural carrier routes and determine pay. Due to flaws in how carriers scanned packages, the algorithm underestimated route times, resulting in pay cuts for 66 per cent of rural carriers, some losing thousands of dollars annually. Carriers report that they were not adequately trained on the system and that the cuts are scheduled to take effect, though they have been postponed multiple times. The USPS stated that the system is the result of a nationally negotiated agreement.

ScaleFactor reportedly failed to deliver promised automated bookkeeping software
ScaleFactor, an Austin-based startup, is reported to have failed to deliver the automated, real-time bookkeeping tools it promised customers, instead relying on human bookkeepers and a Filipino contract accounting firm. The company told Forbes in June that it was shutting down, initially blaming the pandemic, but Forbes later reported that its problems predated Covid-19. Investors reportedly came to see the company as more of a services business than a software platform, and pulled funding after a pivot to a marketplace model. No legal or regulatory action is reported.

The algorithm flagged the request for review, and EviCore's doctors determined it was not medically necessary. Cupp did not receive the procedure and his symptoms continued.
