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.

Uber's Secretive 'Upfront Fares' Algorithm Cuts Driver Pay in Many Cities
Uber introduced an opaque algorithm called 'Upfront Fares' to calculate driver pay in 24 U.S. cities, replacing the previous time-and-distance-based rate. Drivers report lower and unpredictable earnings, with Uber taking a larger cut of fares. The company claims the change gives drivers more control, but critics say the secrecy makes it impossible to verify fair pay. The algorithm may learn the lowest rate drivers will accept, potentially driving down wages.

Dutch city uses black-box algorithm for home valuation
In 2016, the municipality of Castricum, Netherlands, used an algorithm to set the WOZ value of a resident's home at €320,000, affecting their property tax. The resident challenged the valuation, arguing earthquake damage reduced the value, but the municipality could not explain how the algorithm arrived at the figure. On appeal, an Amsterdam court upheld the valuation, finding it reasonable based on comparable sales, but ordered the municipality to pay court costs for failing to provide an explanation as required by GDPR.

DC attorney general sues 14 landlords over RealPage rent collusion
The Attorney General of Washington DC filed a lawsuit against 14 large landlords, alleging they used RealPage's YieldStar software to form “a District-wide housing cartel” that artificially inflated rents. The complaint claims RealPage's pricing algorithm used data supplied by the landlords and pressurised them to follow its rate recommendations, with one firm's internal presentation stating at least 95% compliance was expected. This alleged scheme caused residents to pay millions of dollars above fair market prices during a housing affordability crisis.

Uber and Lyft pricing algorithms charge more in non-white areas
A study of over 100 million rides in Chicago between November 2018 and December 2019 found that Uber and Lyft's pricing algorithms charged higher fares per mile for trips to or from neighbourhoods with higher proportions of non-white residents. The researchers analysed trip data against census demographics and found no statistical link to higher demand in those areas. Both companies acknowledged the study and said they would review the findings, but no changes have been reported.

Allstate's proposed retention model charged big spenders more in Maryland
Allstate proposed an auto insurance rate adjustment plan in Maryland using a retention model algorithm that varied premium changes based on existing premiums. The algorithm would have increased rates up to 20% for customers already paying the highest premiums while capping increases at 5% for others, and would have denied meaningful discounts to thousands owed reductions. The Maryland Insurance Administration rejected the plan as discriminatory, but Allstate claims it was withdrawn and has continued proposing similar models elsewhere. The proposal never took effect in Maryland.

Airbnb smart-pricing algorithm increased racial revenue gap, study finds
A study by Carnegie Mellon University found that Airbnb's smart-pricing algorithm increased the revenue gap between White and Black hosts, even though it narrowed the gap among hosts who adopted it. The algorithm, which sets daily prices automatically, was adopted by fewer Black hosts, so its suggested prices were closer to the optimum for White hosts. The researchers said the tool could reduce racial disparities only if more Black hosts adopted it.
