Navigating the state-specific Medicaid portal requirements for credentialing services in Oregon is critical to avoiding claim denials.

Back to All Resources

Oregon’s Medicaid program operates through 16 Coordinated Care Organizations (CCOs) that function as regionally-based managed care entities — a model unique to Oregon where your geographic location determines which CCOs you must credential with.

Oregon’s CCO Model: Regional Managed Care

Oregon uses Coordinated Care Organizations instead of traditional MCOs. CCOs are regionally assigned — each service area has 1–3 CCOs.

Key CCOs by region:

RegionCCOs
Portland MetroHealth Share of Oregon, CareOregon
Salem/Mid-ValleyPacificSource, Willamette Valley Community Health
EugeneTrillium Community Health Plan
Southern ORJackson Care Connect, AllCare Health
Central ORPacificSource Central Oregon
Eastern OREastern Oregon CCO

Regional Lock: Unlike statewide MCO states, Oregon CCOs are geographically assigned. Credentialing with Portland CCOs is useless for Eugene practices. Research which CCOs serve YOUR specific service area.

Portland Strategy: Health Share of Oregon is the largest CCO in the state. For Portland metro, credential with Health Share first, then CareOregon.
