Kaiser Foundation Health Plan Settles Medicare Advantage Allegations for $556 Million

In a significant legal settlement announced today, Kaiser Foundation Health Plan and its affiliated entities have agreed to pay $556 million to resolve allegations related to Medicare Advantage billing practices. The settlement concludes a lengthy Department of Justice investigation into claims that Kaiser violated the False Claims Act by submitting invalid diagnosis codes to increase government payments.

Federal investigators alleged that Kaiser affiliates systematically submitted inaccurate diagnostic information to the Centers for Medicare & Medicaid Services (CMS), artificially inflating risk scores for Medicare Advantage beneficiaries. The risk adjustment payment model, designed to provide higher reimbursements for patients with more complex medical needs, was allegedly manipulated to secure unwarranted government funds.

“This settlement underscores our commitment to protecting the integrity of federal healthcare programs,” said a Justice Department spokesperson. “Medicare Advantage plans must adhere to the same standards of accuracy and truthfulness as all government contractors.”

The investigation focused on Kaiser’s practices between 2015 and 2022, during which time Medicare Advantage enrollment grew substantially nationwide. The program, also known as Medicare Part C, allows beneficiaries to receive their benefits through private health insurers that contract with the federal government.

Kaiser, which operates one of the nation’s largest integrated healthcare delivery systems serving approximately 12.6 million members across eight states and Washington, D.C., has not admitted wrongdoing as part of the settlement. In a statement, the organization emphasized its commitment to compliance but noted that the settlement was the most prudent path forward.

“While we firmly believe our Medicare Advantage coding practices have been compliant with regulations, continuing this dispute would have required years of costly litigation,” a Kaiser representative stated. “This resolution allows us to focus our resources on what matters most—providing high-quality care to our members.”

The $556 million settlement ranks among the largest involving Medicare Advantage billing practices, highlighting the federal government’s intensified scrutiny of the program. As enrollment in Medicare Advantage plans continues to grow—now covering more than 30 million beneficiaries or roughly half of all Medicare-eligible individuals—regulators have increasingly targeted perceived abuses in the risk adjustment system.

Healthcare compliance experts note that this settlement reflects a broader trend in federal enforcement. “The government has clearly signaled that Medicare Advantage billing practices are a priority enforcement area,” said Sarah Johnson, a healthcare attorney with Hamilton & Partners. “This settlement sends a powerful message to the entire industry about the consequences of improper coding practices.”

The case against Kaiser emerged amid growing concerns about Medicare Advantage’s cost to taxpayers. A series of reports from the HHS Office of Inspector General has suggested that some Medicare Advantage organizations have received billions in improper payments through questionable diagnostic coding practices.

For Kaiser, the settlement comes at a challenging time for the healthcare sector, which continues to face financial pressures from inflation, workforce shortages, and the lingering effects of the pandemic. The organization will likely implement enhanced compliance measures as part of the settlement agreement.

Industry analysts suggest the resolution may trigger similar investigations across the Medicare Advantage landscape. “This settlement establishes a benchmark for future enforcement actions,” noted Michael Thompson, senior healthcare analyst at Brookfield Research. “Other insurers with significant Medicare Advantage portfolios should expect heightened scrutiny of their risk adjustment practices.”

The settlement funds will be returned to the Medicare Trust Fund, which finances benefits for approximately 65 million Americans who rely on Medicare for their healthcare coverage.

The Justice Department has indicated that whistleblowers were instrumental in bringing the alleged violations to light, though specific details about their involvement remain confidential. Under the False Claims Act’s qui tam provisions, whistleblowers may receive a portion of recovered funds as a reward for reporting fraud against government programs.
