AI in Insurance: Automated Claim Denials Spark Regulatory Battles and Consumer Anxiety

Published on 31 March, 2026

The integration of artificial intelligence into the insurance industry is accelerating, with major implications for consumers seeking coverage for medical procedures and property repairs. While industry leaders champion the technology for its speed and efficiency, critics argue that algorithmic decision-making is leading to unjust claim denials and a lack of accountability.


According to a 2024-25 survey by the National Association of Insurance Commissioners (NAIC), approximately 84 percent of health insurers in the United States are already utilizing AI for sensitive processes such as fraud detection and prior authorization. The use of this technology is also growing in the property and auto insurance sectors. However, the rapid adoption has outpaced regulation, leaving many consumers vulnerable to decisions made by machines rather than humans.


Lawsuits Highlight Dangers of Algorithmic Decision-Making


The potential dangers of AI in healthcare are currently under the spotlight due to a class-action lawsuit against UnitedHealth Group. Plaintiffs allege that the insurer used an algorithm to deny nursing home care to Medicare Advantage beneficiaries, a practice they claim resulted in premature discharges and, in some cases, patient deaths.


This case exemplifies the anxiety surrounding AI in insurance. For patients like Iris Smith, an 80-year-old Florida resident, the prospect of AI handling preauthorization is concerning. Smith chose traditional Medicare specifically to avoid the hurdles of commercial preauthorization, fearing that a corporation's algorithm cannot understand the nuances of individual pain and medical necessity.


The Regulatory Landscape and Legislative Struggles


Despite the high stakes, regulation remains fragmented. Florida, a state prone to natural disasters and known for high property insurance premiums, is one of 22 states without specific rules governing AI in insurance. A bipartisan bill recently introduced in the Florida House aimed to mandate human review for all claim denials. State Representative Hillary Cassel argued that no citizen should face a denial based solely on an automated output.


While the bill passed the House, it failed to advance in the Senate following opposition from industry representatives. Insurers contend that AI streamlines operations and reduces costs, which can be passed on to policyholders. They maintain that they remain liable for errors, regardless of whether a human or a machine processes the claim. However, disputes, such as a recent contract standoff between Tenet Healthcare and Cigna over alleged automated denials without human review, suggest that friction remains high.


The Future of Medicare and AI Oversight


The debate is now extending to traditional Medicare. A new pilot program known as the Wasteful and Inappropriate Service Reduction Model (WISeR) has launched in six states. This initiative aims to use enhanced technologies to review claims for specific services susceptible to fraud and waste.


Supporters, like Florida State University professor Evan Saltzman, view this as an inevitable shift toward the efficiencies seen in the private sector. However, critics, including U.S. Representative Lois Frankel, vow to fight the expansion of AI reviews in Medicare. They argue that the foundational promise of Medicare is to provide care when a doctor deems it necessary—not when an algorithm approves it.


As AI capabilities expand, the insurance industry faces a critical challenge: balancing the undeniable efficiency of automation with the ethical imperative to protect patients and policyholders from potentially harmful automated errors.
