Oregon Health Plan 1115 Demonstration Waiver


Section 1115 Medicaid Demonstrations give states flexibility to design and improve programs and to show how new policy approaches such as eligibility expansion, service expansion or using innovative service delivery systems can improve care, increase efficiency, and reduce costs.

Under 1115 authority, states may receive approval to waive some requirements of their Medicaid or CHIP state plans to test new approaches to paying for and delivering covered services and defining or limiting benefit packages.

Oregon's initial 1115 Medicaid Demonstration waiver established the original groundbreaking Oregon Health Plan (OHP) in 1994. Since then, the Demonstration has given Oregon numerous opportunities to expand and improve health care throughout the state.

Oregon's Current Demonstration

Oregon's current OHP 1115 Medicaid Demonstration runs from Oct. 1, 2022, through Sept. 30, 2027. It advances OHA's goal of eliminating health inequities by 2030, exploring different ways to affect health outcomes for communities and groups that have been disproportionately affected by health inequities in our state..

In February 2022, the Oregon Health Authority submitted the final application to CMS, whose approval is needed to implement policies reflected in the application. If approved, Oregon would make changes to OHP during the 2022 – 2027 demonstration period.

Oregon's Waiver History

1994: Established the Oregon Health Plan (OHP). This made most people living in poverty eligible for Medicaid, regardless of age, disability or family status. It also based coverage on the Prioritized List of Health Services​​. This list defines the health condition and treatment pairs that OHP covers in priority order.

1997: Gave Children’s Health Insurance Program (CHIP) members the same benefits and delivery system as Medicaid members.

2002: Established OHP Plus and OHP Standard benefits. Added the Family Health Insurance Assistance Program.

2007 and 2009: Expanded CHIP and established the Healthy Kids program.

2012: Established the coordinated care model and initiated Health System Transformation. Read the Evaluation of Oregon's 2012-2017 Medicaid Waiver​.

The 2017-2022 OHP 1115 Medicaid Demonstration ran from Jan. 12, 2017, through Sept. 30, 2022. It continued and expanded all elements of the 2012 waiver, particularly around integration of behavioral, physical and oral health integration, and include a focus on social determinants of health, population health, and health care quality. 

It promotes a performance-driven system to improve health outcomes and bend the cost curve. It includes:

  1. An expanded focus on the integration of physical, behavioral, and oral health care.
  2. A strong focus on social determinants of health and health equity to improve population health outcomes for all low-income Oregonians.
  3. A commitment to an ongoing sustainable rate of growth. The 2-percent test puts the federal investment at risk for not meeting that target. CCO payment and contracting protocols promote increased investments in health-related services and use of value-based payments.
  4. Expanding the coordinated care model with innovative strategies for ensuring better outcomes for members eligible for both Medicare and Medicaid.
