Insurance coverage denials have increased in the U.S. in recent years, driven in part by automated algorithms powered by AI, and recently launched artificial intelligence tools could fight back by generating automated appeals. There is a gender.
But to see more lasting change, health experts say health insurance systems need bigger reforms to control high prices and ensure coverage.
UnitedHealth, Humana and Cigna are facing class action lawsuit Insurers claim they relied on algorithms to deny life-saving care.
One of the lawsuits alleges that Cigna denied more than 300,000 claims over a two-month period. 1.2 seconds For each claim referred to by a physician. Such practices are aided by algorithms, the lawsuit said.
In 2020, UnitedHealth Group acquired Navihealth and its algorithm to predict care called NH Predical. (A UnitedHealth Group spokesperson denied that algorithms are used to make coverage decisions. Huemer did not respond to a request for comment.)
The lawsuit against them alleges that NH's predictions have a 90% error rate and that 9 out of 10 denials are reversed on appeal, but they are unable to appeal denied claims and pocket bills. The patients (approximately 0.2%) who were led to pay from the Withholding necessary treatment.

Two of her three sons have severe food allergies, so Deirdre O'Reilly was worried about sending one of them to college out of state. When he reacted, he went to the emergency room as usual.
But this time, the insurance company refused to cover the entire visit – nearly $5,000, according to a rejection letter reviewed by the Guardian. O'Reilly tried to appeal four times, and each time, she said, her Vermont insurance company, Bluecross BlueShield, gave her another reason.
“My son had no choice. If he didn't go to the nearest emergency room, he would die,” O'Reilly said.
She should know. She is an intensive care physician at the University of Vermont. She has seen this kind of denial happen to her patients, including premature babies who are refusing oxygen machines.
“It's gotten out of control. In the 20 years I've been a doctor, it's changed a tremendous amount,” she said. “I can't believe people have to go through this just to have health care covered. It's something that is a basic need.”
And many people don't have the same medical expertise and the time or resources for a lengthy appeals process.
“I'm persistent,” she said. “But at one point, I was able to fight that much.”
A BlueShield Vermont spokesperson said in a statement that the company cannot comment on individuals' health records but rejects the use of algorithms in managing care. “Most” previous authorization decisions were made by the insurer's team of doctors and nurses based on national guidelines, she said.
Vermont is one of several states that recently passed legislation to reduce preclearance tensions.
Automated denials in particular are facing increased scrutiny from federal and state legislators.

UnitedHealthCare, CVS, and Humana – the three largest providers of Medicare Advantage and provide nearly 60% of all Medicare Advantage coverage – use technology and automation to preauthorize at higher rates, according to the U.S. Senate refuse the claim report Released in October.

ai can help Make sure your forms are coded and formatted according to each insurance company's specifications, she said. It can also be used by insurance companies approve Insurance is requested more quickly.
UnitedHealth Group CEO Andrew Whitty said in a profit call last week that most denials occur because of errors in filling out or submitting this form, executives said UnitedHealthcare's revenue in 2024 will be 300 million yen. dollar, and said he expected that number to rise. 340 billion dollars in 2025.
Witty estimated that 85% of denied claims could be avoided “through a more standardized approach to technology across the industry.”
The resourcefulness is to change to industry standards, instead of each company having a different form and process.
But having human oversight of automated processes is a necessary change, experts said.
“These algorithms don't always get it right, so I think there's a fear that a lot of the human side is being pulled out of the system” of public health.
California recently enacted legislation to prohibit AI from making compensation decisions and require physician oversight.
But just addressing AI doesn't fix some of the problems underlying automation decisions, Hamer said, including empty prices for health care and drugs.
“One in every five dollars of U.S. GDP is spent on health care,” Hamer says. “It's absolutely a massive system. It needs a major overhaul.”
