“(UnitedHealthcare's) parent group UnitedHealth has a market valuation of $560 billion and was the eighth largest corporation in the world last year as measured by revenue. This year, UnitedHealthcare—Thompson’s unit—is expected to bring in $280 billion in revenue." Richardson continues. "The lawsuit alleges that UnitedHealthcare uses artificial intelligence to deny claims from Medicare Advantage policyholders. The lawsuit claims that the company knowingly uses an algorithm that makes errors 90% of the time because it also knows that only about 0.2% of policy holders will appeal the decision to deny their claims. Last month the Senate Permanent Subcommittee on Investigations hammered UnitedHealth for dramatic increases in their denial rates for post-acute care between 2019 and 2022 as it switched to AI authorizations.”
