QuickTake:
Trillium, a Medicaid insurer, will absorb about 92,000 Lane County residents enrolled in the Oregon Health Plan who rely upon PacificSource for coverage.
Nearly 70% of Lane County residents on Medicaid will see their health care coverage shift from PacificSource Community Solutions to Trillium Community Health Plan.
Both insurers are coordinated care organizations, or CCOs, and contract with the state to deliver Oregon Health Plan services. About 92,000 people in Lane County currently use PacificSource; another 30,000 use Trillium.
In September, the Oregon Health Authority ended contract negotiations with PacificSource, which cited financial issues. The state plans to transition members from the Springfield-based insurer to Trillium over the next few months.
Here’s what we know so far — and what we don’t — about a major change in a complex system.
Can Trillium absorb more than 92,000 new members?
The health care community has raised concerns about Trillium’s capacity and its provider network, which has seen changes in recent years.
Dave Baden, the health authority’s deputy director for policy and programs, said Trillium’s network will expand as part of the transition.
A Trillium spokesperson, representing the Centene Corp.-owned insurer, told Lookout Eugene-Springfield the company has the capacity to absorb nearly 92,000 new members and is ready to meet their needs.
Should PacificSource members switch now?
No. Baden said PacificSource members should wait for instructions from the health authority and their CCO before making any changes.
Will physicians and services change?
PacificSource members will not see immediate changes. Any adjustments in 2026 remain to be seen.
Will coverage be disrupted?
The health authority says it’s working to minimize disruptions by prioritizing high-risk patients and extending PacificSource’s contract.
Members will be grouped by care level to ensure a smooth exchange of medical records. Those receiving dialysis, cancer treatment, or post-surgical care — as well as transplant patients and people on critical medications — will receive additional coordination.
A one-month contract extension with PacificSource will give providers time to continue services as Trillium expands its network.
How will members be notified?
PacificSource is working with the health authority to prepare and distribute notices. The notices will include websites and phone numbers for members seeking help or information.
Such notifications should happen once the health authority approves PacificSource’s transition plan. The authority approved the plan Oct. 24.
A spokesperson for the health authority said in an email Oct. 23 that members can expect communication in the “coming weeks” and that the agency is planning community forums. She did not clarify if the forums are in person, online, or both.
When will the transition be complete?
The state aims to complete the handover by Feb. 1. If some providers haven’t joined Trillium’s network by then, the health authority says time will be added for continuing care.
