Integrated Co-occurring Disorders


Co-occurring disorders (COD, also known as dual diagnosis) means having more than one behavioral health disorder. 

  • These can be substance use, gambling, intellectual and developmental disability (I/DD) and mental health disorders.
  • Each disorder can cause symptoms of the other disorder, leading to slow recovery and reduced quality of life.

The high rate of co-occurrence among disorders argues for a comprehensive approach to intervention that identifies, evaluates, and treats each disorder concurrently. Concurrent COD treatment is the expectation for both addictions and mental health service providers. 

Integrated COD Program

For many years, research and best practices have indicated that an integrated approach to COD treatment is best; however, Oregon providers lacked the broader system supports and payment models needed to achieve this goal. To close this gap, House Bill 2086 (2021) directs the Oregon Health Authority (OHA) to:

  • Reimburse for COD treatment services at an enhanced rate based on clinical complexity and the education level of the treating provider.
  • Provide one-time start-up funding for programs that provide Integrated COD treatment.
  • Study reimbursement rates for COD treatment, including treatment of co-occuring I/DD and gambling disorder. 

To do this work, OHA worked with community partners to establish the Integrated COD program for Oregon Health Plan (Medicaid) members. The program will also:

  • Offer training, support and resources for provider agencies and staff to provide integrated COD treatment. 
  • Use a single payment model for integrated treatment services.
  • Develop a specialty clinical endorsement/credential for Integrated COD treatment and support providers.
  • Advance higher quality care to meet the needs of all Oregonians dealing with COD.
