For years, disputes over how health insurers handle money for self-funded employer health plans have played out in the federal courts as ERISA cases. A new lawsuit from Kansas shows how the same conduct can take on a different legal shape when the plan is funded by taxpayers.
On June 24, 2026, Kansas Attorney General Kris Kobach filed suit against Aetna in Shawnee County District Court, alleging that the insurer used money from the state employee health plan to benefit itself. The state is pursuing relief under the Kansas False Claims Act and seeks restitution, penalties, and disgorgement. Aetna denies the allegations.
What Kansas Alleges Aetna Did
Aetna is one of two third-party administrators (TPAs) for the Kansas State Employee Health Plan, which is self-funded. The state pays for its employees’ claims, and Aetna processes them, deciding how claims are priced, how much providers are paid, and whether payments are later reversed or recouped. The lawsuit focuses on two practices.
The first is known as cross-plan offsetting. According to the state, when Aetna overpaid a provider under a separate, fully insured plan, it recovered that money the next time the same provider treated a state employee. Aetna allegedly drew the full claim amount from the state plan, paid the provider only part of it, and kept the difference to cover its own loss on the other plan. The state alleges that neither it, the provider, nor the employee was told this was happening.
The second involves out-of-network claims. Kansas alleges that Aetna sent these claims through its National Advantage Program, which relied on outside repricing vendors to reduce what providers received, while charging the state fees that were not properly disclosed.
Why These Claims Are Being Brought Under the False Claims Act
Cross-plan offsetting is not a new allegation. In 2021, a federal court in New Jersey ruled in Lutz Surgical Partners v. Aetna that Aetna’s use of the practice violated ERISA because it breached the duty of loyalty owed to plan members and amounted to prohibited self-dealing. The U.S. Department of Labor has taken the same position, and in 2023, it reached a settlement with EmblemHealth that required the insurer to stop cross-plan offsetting and reimburse affected workers and families.
However, ERISA does not apply to health plans sponsored by state and local governments. Governmental plans are exempt from the statute, so a state cannot rely on ERISA’s fiduciary rules to recover money taken from its own employee health plan. State false claims laws fill that gap. When a TPA draws funds from a state-funded plan, each request is a claim on public money.
If the TPA knows the amount it is drawing does not match what it paid providers, or it charges fees the contract does not allow, that claim may be false. Conduct that would be framed as a breach of fiduciary duty in a private employer’s plan can support False Claims Act liability when the government is the one paying.
New Jersey Has Already Recovered $100 Million on a Similar Theory
Kansas is not the first state to pursue a health plan administrator this way. In November 2025, New Jersey announced that Horizon Blue Cross Blue Shield of New Jersey agreed to pay $100 million to settle allegations under the New Jersey False Claims Act. The state alleged that Horizon won a 2020 contract to administer the state’s employee health benefit programs, knowing that it could not comply with a contract term requiring it to charge the state the lower of the provider’s billed amount or the negotiated rate.
The state further alleged that Horizon then overcharged it throughout the contract. Horizon characterized the matter as a contract dispute and denied any intentional wrongdoing.
The Horizon case began as a qui tam lawsuit filed by private whistleblowers in 2021. The federal government declined to intervene, but New Jersey investigated and pursued the case on its own. The whistleblowers received a portion of the state’s recovery, and the settlement is the largest non-Medicaid false claims resolution in New Jersey’s history.
Whistleblower Rights Depend on the State
Whether a whistleblower can file a qui tam lawsuit on behalf of a state depends on that state’s false claims law. Many states, including California and New Jersey, allow private individuals to file a complaint on the state’s behalf and receive a portion of what the state recovers. The Kansas False Claims Act does not include a qui tam provision, although it does protect employees from retaliation for reporting fraud. That is why the Kansas case was filed directly by the attorney general.
The California False Claims Act covers claims for payment from the state as well as from counties, cities, school districts, and other local government entities. Insurers and TPAs that administer health benefits for California public employers can face liability under the statute when they bill public funds improperly.
Who Is Positioned to Report This Conduct
The people most likely to see these practices work inside the claims payment process, including claims processors, payment integrity and overpayment recovery staff, finance and reconciliation employees, account managers who handle public employer clients, and employees of repricing vendors. Provider billing staff who see unexplained reductions or claw-backs on payments for public employee patients, and government benefits staff who review TPA invoices, may also be able to spot the problem.
Speak to a Whistleblower Attorney About Coming Forward
If you have knowledge of an insurer or TPA using a government-funded health plan’s money to cover its own losses, charging undisclosed fees, or billing a public employer in ways its contract does not permit, you may be able to file a qui tam lawsuit on the government’s behalf.
