Oregon Medicaid Payer IDs: OHA, CareOregon, PacificSource and Trillium

As of October 9, 2026, the verified Oregon Medicaid payer IDs below cover OHA fee-for-service and three CCO billing destinations. Start with the member’s date-of-service eligibility and service coverage, then select the payer. This is a bounded medical and behavioral health reference, not a directory of every Oregon CCO.

The Trillium manual also shows a separate vision payer ID on the sample card. Use the medical/BH destination above for this guide’s scope; do not copy a vision field into your therapy payer record. Check the manual’s member-identification section.

Do not mix products or identifier types

PacificSource lists Medicaid 20416 separately from commercial 93029 and Medicare 20377. Its page also lists clearinghouse trading partner IDs. Those are different fields from the product’s payor ID. Compare PacificSource’s published identifiers.

In your EHR or clearinghouse, inspect the payer display name and product alongside the ID. If the search returns several similar names, open the details before saving. Ask the clearinghouse which entry supports your intended claim transaction rather than selecting the first name match.

Do not assign CareOregon’s ID to every plan that shares a county or umbrella CCO name. Use the member’s service-specific coverage and the plan’s billing instructions to establish responsibility. Our CCO directory by county helps find plans, but geography alone does not select the claim destination.

Lane County: use the service date

A Lane County client’s current plan should not automatically overwrite the payer for an older visit. The PacificSource-to-Trillium transition guide explains the February 2026 change and follow-up checks. Keep the coverage evidence for the original service date beside any historical claim you are correcting.

What if your CCO is not in this table?

Use OHA’s CCO provider contact directory to locate the plan, then check its current claims manual and your clearinghouse’s payer listing. Record the source and review date in your payer setup notes. We have left unconfirmed IDs out of this table rather than assigning a number from a similarly named plan.

• Confirm the responsible payer and product for the date and service.

• Compare the official ID with the exact claim destination available in your clearinghouse.

• Check provider enrollment, network participation and authorization requirements as separate tasks.

• After sending, review the clearinghouse/payer response before treating the claim as accepted.

For account problems that prevent checking the coverage record, start with MMIS login, lockout and PIN help. For an enrollment notice rather than a claim rejection, see Oregon provider revalidation.

Frequently Asked Questions

Is ORDHS the payer ID for every Oregon Medicaid claim?

OHA publishes ORDHS for its fee-for-service claims. Establish whether OHA or a CCO covers the service before choosing the destination.

Can I use a trading partner ID as the payer ID?

Do not substitute one identifier field for another. Match the claim destination and transaction setup using the payer’s and clearinghouse’s current instructions.
