Lane County OHP: PacificSource to Trillium

Last updated: July 5, 2026.

If you see Oregon Health Plan (OHP) clients in Lane County, the coordinated care organization (CCO) landscape under you has already changed. PacificSource Community Solutions no longer operates as a CCO in Lane County. Effective February 1, 2026, Lane County OHP members moved to Trillium Community Health Plan. PacificSource was responsible for members through January 31, 2026; Trillium took over on February 1. This is not an upcoming change to plan for — it happened, and the practical question now is whether your billing has caught up with it.

This post is a "what to verify now" checklist for Lane County therapists and practice managers: confirm each client's current CCO, route claims and authorizations to the right plan, and make sure you are actually contracted with Trillium so those visits pay in-network. It sits under our Oregon Medicaid credentialing pillar guide, which maps how OHP, the MMIS Provider Portal, and CCOs fit together.

TL;DR: PacificSource stopped being a Lane County CCO. Former PacificSource OHP members in Lane County were automatically enrolled in Trillium Community Health Plan on February 1, 2026 (American Indian/Alaska Native members moved to OHP Open Card unless they chose Trillium). Re-verify eligibility and CCO assignment for every affected client, send new prior-authorization requests to Trillium, route claims to the member's current plan, and confirm your Trillium contract and credentialing status. Being enrolled with OHP does not make you in-network with Trillium — that is a separate contract.

What Changed in Lane County

Oregon Medicaid is delivered mostly through CCOs — regional managed-care plans that hold their own provider networks, contracts, prior-authorization rules, and claims systems. For years, Lane County OHP members could be enrolled with PacificSource Community Solutions. That ended.

Per the Oregon Health Authority (OHA), PacificSource Community Solutions ceased serving as a CCO in Lane County, and OHA, Trillium, and PacificSource coordinated a transition of affected OHP members to Trillium Community Health Plan. PacificSource remained responsible for covered services through January 31, 2026, and Trillium assumed responsibility beginning February 1, 2026. OHA's current coordinated care organization list now shows Trillium Community Health Plan – Southwest serving all of Lane County (along with western Linn and western Douglas counties), and PacificSource is no longer listed for Lane County — confirming the change is in effect.

One population moved differently. According to OHA, members who are American Indian/Alaska Native were automatically moved to OHP Open Card (fee-for-service) on February 1 unless they chose to enroll in Trillium. That distinction matters for billing: an Open Card member's claims and authorizations go through OHA's fee-for-service lane, not through Trillium. Do not assume every former PacificSource member is now a Trillium member.

Why This Matters for Therapists

A CCO change is not a cosmetic relabeling. When a client's plan changes, so does the plan that pays your claims, the network you have to be in, the portal you check eligibility on, and the entity that must approve authorized services. If your systems still point at PacificSource for a Lane County client, you can expect the predictable failure modes:

• Claims denied for wrong payer. A claim sent to PacificSource for a February-or-later date of service has no valid coverage to pay it.

• Out-of-network denials. The client is now a Trillium member, but you never contracted with Trillium, so the visit is out-of-network.

• Lapsed authorizations. A prior authorization PacificSource issued does not automatically become a Trillium authorization forever — continuity-of-care protections are time-limited.

• Eligibility surprises. You verify against the old plan, see nothing wrong, and only find out at denial time that the member is now Trillium or Open Card.

What Providers Should Verify Now

Because the transition is already effective, treat this as an operational cleanup rather than advance planning. Work through each item for every Lane County OHP client on your caseload:

1. Current CCO assignment for each client (Trillium, Open Card, or something else).

2. Your Trillium contract and credentialing status for the providers and locations rendering care.

3. Open prior authorizations that were issued by PacificSource and now need Trillium.

4. Claims routing in your EHR/clearinghouse so new dates of service go to the right payer.

5. Client-facing communication so members know their card and plan changed.

Eligibility and CCO Assignment Checks

The single most useful habit right now is re-verifying eligibility and CCO enrollment before you bill — ideally before each session. Oregon's MMIS Provider Portal shows free, real-time OHP member eligibility and CCO enrollment, so it will tell you the plan of record on the date you check. Confirm three things for every Lane County client:

• That the member still has active OHP coverage.

• Which plan they are in now — Trillium, OHP Open Card (fee-for-service), or another CCO if they relocated or changed.

• The effective date of the current assignment, so you route each date of service to whichever plan covered it that day.

Remember that the portal reports current and historical coverage (OHA allows up to 13 months of history) but does not verify future-dated eligibility, so re-check close to the service date. We walk through the mechanics in how to verify OHP eligibility across CCO and Open Card.

Claims After the Transition

Claims follow the member's plan on the date of service, and the split is clean at the transition line:

• Dates of service through January 31, 2026: PacificSource was the responsible CCO for members who were enrolled with it, so those claims belong in the PacificSource lane.

• Dates of service on or after February 1, 2026: Trillium is the responsible CCO for members who moved to Trillium — submit those claims to Trillium under your Trillium billing setup.

• American Indian/Alaska Native members on Open Card: their post-transition claims go through OHA fee-for-service (Open Card), not Trillium — unless they affirmatively chose Trillium.

If you have February-or-later claims that were sent to PacificSource and denied, rework them to the correct payer rather than resubmitting to the old plan. For the broader routing logic between the two lanes, see Oregon Medicaid claims: Open Card vs. CCO.

Authorizations and Continuity of Care

OHA built transition-of-care protections into the change so members did not lose access mid-treatment. Under OHA's guidance, approved services generally continued temporarily after the switch — for most OHP members roughly 60 days of continuity for physical, dental, and behavioral health care, and about 90 days for Medicare-eligible members, with longer protection for people in the middle of treatment for high-risk conditions.

The catch, several months in: those continuity windows were measured from the February 1, 2026 transition, so most of them have already closed. An authorization PacificSource issued should not be assumed to still cover an ongoing course of care under Trillium today. If a client is still receiving authorized services, confirm the authorization now exists on the Trillium side and submit a fresh request to Trillium if it does not.

OHA's direction to providers through the transition was consistent: keep serving members regardless of the CCO change, and send new authorization requests to the member's new CCO. Behavioral-health prior-authorization rules differ by plan, so treat Trillium's requirements as the source of truth for Trillium members and OHA's fee-for-service rules for Open Card members. For the general framework, see prior authorization for OHP therapists.

Trillium Provider Participation and Contracting Checklist

This is the step practices most often skip. Your OHP/Open Card enrollment with OHA is not the same as being in Trillium's network. To bill Trillium in-network and get paid, you need a Trillium contract and Trillium credentialing — a separate process from your state enrollment. Trillium credentials providers before adding them to the network, using NCQA- and OHA-aligned standards, and reports processing complete credentialing applications within about 30 days.

Work down this checklist:

• Confirm whether you are already contracted with Trillium. Many Lane County practices only held PacificSource CCO contracts and were never in Trillium's Southwest network.

• Verify each rendering provider is credentialed with Trillium, not just the group or billing NPI.

• Check behavioral-health provider-type rules. Trillium enrolls a range of BH provider types (it added Board-Registered Associates to BH group-practice credentialing in 2023), and MHACBO-certified practitioner types generally require the agency to hold a Certificate of Authority (COA) with OHA.

• Confirm your service locations and effective dates so claims match Trillium's records.

• Contact Trillium provider services / your Provider Engagement Account Manager for contracting, credentialing status, portal access, and billing procedures.

Do not assume you will be accepted or that a contract is instantaneous — network participation is Trillium's decision and its own timeline. If you are weighing which Oregon CCOs to join, the credentialing-vs-contracting distinction is covered in OHP enrollment vs. CCO credentialing, and a neighboring-plan example lives in CareOregon and Health Share credentialing for therapists.

Client Communication Script

Members received OHA notices about the change, but a short, plain-language check-in from your front desk prevents no-shows and coverage gaps. Something like:

"We want to make sure your Oregon Health Plan coverage is up to date. Lane County OHP members recently moved from PacificSource to a plan called Trillium Community Health Plan. Can you confirm which plan you're in now, and bring your current OHP or Trillium member ID card to your next visit? If you got a letter from the Oregon Health Plan about a plan change, that's what this is — your benefits stay the same, but we need your current plan on file so your visits are covered."

For a client who turns out to be on Open Card rather than Trillium, note it — their billing path is different, and knowing early avoids a denial later.

Action Steps for Providers

1. Pull your Lane County OHP client list. Anyone who was a PacificSource member is affected.

2. Re-verify eligibility and CCO assignment in the MMIS Provider Portal for each — Trillium, Open Card, or other.

3. Confirm your Trillium contract and per-provider credentialing before billing Trillium members in-network.

4. Audit February-or-later claims for wrong-payer denials and rework them to the correct plan.

5. Re-check open authorizations. Continuity windows from February 1 have largely closed — get active services authorized by Trillium.

6. Update your EHR/clearinghouse payer mapping so new Lane County claims route to Trillium (or Open Card) automatically.

7. Send clients a short plan-confirmation message and collect current member ID cards.

8. Keep verifying at each visit until your caseload is fully reconciled.

Where Bomi Fits

A CCO transition is exactly the kind of behind-the-scenes payer change that quietly erodes a practice's Medicaid revenue: the care keeps happening, but the claims start bouncing because the plan underneath the client moved. Bomi helps therapy practices stay on top of that operational work — eligibility and CCO checks, claims, denials and rework, credentialing and payer-enrollment tracking, prior-authorization follow-up, and EOB review — inside the EHR you already use. For a change like Lane County's, that means catching members who moved to Trillium (or Open Card), routing each date of service to the right plan, and flagging where a Trillium contract or authorization is missing.

You can see how we approach credentialing and billing operations, or start from the Oregon overview.

The honest version: Bomi cannot make Trillium contract with you or guarantee a claim pays — no billing partner can. What we can do is keep eligibility, CCO assignment, claims routing, authorizations, and contract status straight through a transition like this, so fewer Lane County OHP dollars fall into the gap between the old plan and the new one.

Bottom Line

PacificSource is no longer a Lane County CCO. As of February 1, 2026, Lane County OHP members are with Trillium Community Health Plan (or, for some American Indian/Alaska Native members, OHP Open Card). The work now is verification: confirm each client's current plan, make sure you are contracted and credentialed with Trillium, re-authorize ongoing services, and route claims to the plan that actually covered the date of service. Because CCO rules are plan-specific, always confirm the current details directly with OHA and Trillium.

FAQ

Did PacificSource leave Lane County OHP?

Yes. PacificSource Community Solutions stopped serving as a coordinated care organization (CCO) in Lane County. It remained responsible for members through January 31, 2026, and OHA transitioned affected Oregon Health Plan members to Trillium Community Health Plan effective February 1, 2026. PacificSource still operates as a CCO in other Oregon regions.

When did most members move to Trillium?

On February 1, 2026. Lane County OHP members enrolled with PacificSource were automatically moved to Trillium that day, with OHA transition-of-care protections continuing approved services temporarily (roughly 60 days for most members, about 90 days for Medicare-eligible members, and longer for high-risk treatment in progress).

Should providers re-check eligibility?

Yes — for every Lane County OHP client. Use the MMIS Provider Portal to confirm active coverage and the current plan (Trillium, Open Card, or other) before billing, ideally before each session. The portal shows real-time eligibility and CCO enrollment plus up to 13 months of history, but it cannot verify future-dated coverage, so check close to the date of service.

What happens to prior authorizations?

Authorizations do not transfer permanently. OHA's transition-of-care rules let approved services continue for a limited window after February 1, 2026, but those windows have largely closed by now. For any ongoing authorized service, confirm the authorization exists on Trillium's side and submit a new request to Trillium if it does not. Open Card members follow OHA fee-for-service authorization rules instead.

Do therapists need to contract with Trillium?

To bill Trillium in-network, yes. Being enrolled with OHP or holding an old PacificSource contract does not make you part of Trillium's network. You need a Trillium contract and Trillium credentialing (credentialing precedes network participation and is typically processed within about 30 days of a complete application). Contact Trillium provider services or your Provider Engagement Account Manager to confirm or start the process.

What about American Indian/Alaska Native members?

OHA moved American Indian/Alaska Native members who were enrolled with PacificSource in Lane County to OHP Open Card (fee-for-service) on February 1, 2026 — unless they chose to enroll in Trillium. For those Open Card members, verify eligibility through the MMIS Provider Portal and route claims and authorizations through OHA fee-for-service rather than Trillium.
