Oregon CCO and Medicaid Transition for Young Adults with Disabilities

Oregon delivers its Medicaid benefits through coordinated care organizations — regional managed care networks that coordinate physical health, behavioral health, and dental services for OHP members. For families navigating the age-18 transition, the CCO layer adds complexity that most benefit guides ignore. Your young adult's CCO assignment, renewal cycle, and eligibility pathway all shift when they move from child to adult Medicaid.

How CCOs Work in Oregon

Oregon has 16 coordinated care organizations covering every county in the state. When someone enrolls in the Oregon Health Plan, they're assigned (or allowed to choose) a CCO based on their county of residence. The CCO is the entity that manages the member's care — choosing a primary care provider, authorizing specialist referrals, and coordinating behavioral health services.

For children with disabilities who grew up on their parent's OHP coverage, the transition to adult OHP means a new eligibility determination as an individual — and potentially a new CCO assignment if the young adult has moved or if their eligibility pathway changes.

The ONE System Application

All Oregon Health Plan applications now go through the Oregon Eligibility (ONE) system, which is the integrated online portal for OHP, SNAP, TANF, and ERDC. Families can apply online at ONE.Oregon.gov, by phone, in person at a local DHS office, or through a community partner organization.

For SSI recipients, SSI can establish the financial basis for OHP coverage through the OSIPM pathway, but a separate OHP application through ONE is still required. If a young adult applies for OHP before their SSI is approved (or if their SSI is denied at the age-18 redetermination), they'll need to apply through ONE as an individual.

The ONE system determines which OHP program the applicant qualifies for:

• MAGI Medicaid (OHP Plus): for adults under 138% of the Federal Poverty Level ($1,836/month for a single person in 2026), no asset test
• OSIPM: for individuals with a certified disability, SSI recipients, or those aged 65+, with a $2,982/month income cap and $2,000 resource limit

The pathway matters because it affects renewal frequency, work requirements, and which services are covered. MAGI adults may face 6-month renewals and work activity requirements under Oregon's approved 1115 waiver changes, while OSIPM enrollees remain on 12-month cycles and are exempt from any work mandate.

The 1115 Waiver and What's Changing

Oregon's Medicaid program operates under a Section 1115 demonstration waiver, which gives the state flexibility to design its OHP benefit structure differently from standard Medicaid rules. The current waiver has been periodically renewed and amended since Oregon first pioneered managed care Medicaid in the 1990s.

Beginning in late 2026 and extending into 2028, Oregon is implementing several changes to OHP enrollment and renewal policies under its updated 1115 waiver terms:

• Standard MAGI adults aged 19–64 will transition from 24-month continuous eligibility to 6-month renewal cycles
• New work or community engagement requirements may apply to certain adult populations
• Individuals enrolled through a disability-based pathway (OSIPM, Medicare dual-eligibles) are explicitly protected from these changes — they keep 12-month renewals and are exempt from any work requirements

For young adults with disabilities, the critical question is which pathway they're on. If your young adult qualifies through OSIPM (because they receive SSI or have a certified disability), the waiver changes don't apply. If they're enrolled through MAGI only — for example, because they're low-income but their SSI application is still pending — they could face the shorter renewal cycle. The disability-based OSIPM pathway retains the stronger protections described above.

Youth with Special Health Care Needs

Oregon's Title V Maternal and Child Health program includes services for Youth with Special Health Care Needs (YSHCN) through the Oregon Health Authority. These services — which include care coordination, transition planning support, and connections to specialty providers — are available during the pediatric years but phase out as the young person enters the adult system.

The practical gap this creates is in care coordination. During childhood, the pediatric CCO care coordinator and the YSHCN program staff help families navigate specialist referrals and prior authorizations. After 18, the adult CCO care coordination infrastructure is thinner, and families must advocate more actively for the same level of service management.

If your young adult has complex medical needs alongside their developmental disability, ask their CCO about care coordination or health home services for high-needs members. Oregon's CCO contracts require these programs, but enrollment is often not automatic — you have to request it.

Coordinating CCO Coverage with ODDS Services

The CCO covers medical services — physician visits, prescriptions, hospitalization, behavioral health therapy. ODDS waivers and the K Plan cover long-term services and supports — personal care, respite, residential services, employment support. These are separate funding streams managed by different entities, and they don't communicate well with each other by default.

The Individual Support Plan developed through the young adult's CDDP or Brokerage should include provisions for coordinating with the CCO on behavioral health services, psychiatric medications, and durable medical equipment. If your young adult's behavioral support needs are addressed by both an ODDS-funded behavior specialist and a CCO-funded therapist, make sure both providers have shared authorization and aren't duplicating or contradicting treatment approaches.
