MultiPlan, which rebranded as Claritev in February 2025, processes payments for out-of-network healthcare services. On June 3, 2025, a US District judge in Chicago ruled that healthcare providers can pursue claims that MultiPlan and a group of insurers conspired to underpay them billions of dollars in reimbursements for out-of-network services. Major insurers, including defendants United Health, Aetna and Cigna have contracts with the company and use its software. MultiPlan processes more than 80% of out-of-network claims across the country, or about 370,000 daily claims according to the plaintiffs. In a statement, attorneys for the health providers said MultiPlan and the insurance defendants “orchestrated a cartel through the sharing of competitively sensitive confidential pricing information to illicitly coordinate on out-of-network reimbursements.”
