The corporate owner of Trillium Community Health Plan, the organization that provides Oregon Health Plan benefits in Lane County, has told Wall Street its Medicaid business is deteriorating, and its 2025 financial results would be worse than previously expected.
Centene Corp., a publicly traded Medicaid and Medicare health insurance provider headquartered in St. Louis, acquired Trillium in 2015. Trillium started as the Lane Individual Physicians Association.
Trillium serves parts of six counties (Clackamas, Douglas, Lane, Linn, Multnomah and Washington). It is one of the 16 coordinated care organizations that provide Oregon Health Plan benefits to 1.4 million Oregonians, including 57% of the state’s children.
On July 1, Centene issued a statement saying it was withdrawing the previous guidance it had provided to Wall Street analysts about its 2025 financial results after reviewing data from the first half of the year. In effect, the company said, conditions — particularly in its Medicaid businesses — had deteriorated.
The company’s stock plummeted 40% the next day, from $56.65 to $33.78. On July 7, Bloomberg reported that Standard & Poor’s Global, a bond ratings agency, was considering lowering its rating on Centene to junk status. That would significantly increase Centene’s borrowing costs.
It is unclear what impact Centene’s issues might have in Oregon. A Trillium spokesperson declined to comment.
The larger context is President Donald Trump’s “big beautiful bill” and its impact on the Oregon Health Plan. Nationally, cuts to Medicaid over the next decade are forecast to total more than $1 trillion and cost 10.8 million people their health insurance, according to the nonpartisan Congressional Budget Office.
Few states have been more aggressive than Oregon at seeking creative and expansive ways to use federal Medicaid dollars.
