Medication assisted treatment (MAT)

Medication assisted treatment (MAT) is an approach to opioid use treatment that combines the use of FDA-approved drugs with counseling and behavioral therapies for people diagnosed with opioid use disorder (OUD).

What do I need to know as a provider?

MAT is used at opioid treatment program (OTP) facilities as a method for assisting patients in recovery. If you have a patient in need of these services, refer to our listing of opioid treatment programs (OTP) in Washington State.

In addition, the Washington State Targeted Response (STR): Hub and Spoke Project funds multiple, geographically-based, integrated networks of care — called hub and spoke networks — for OUD treatment.  

On October 1, 2018 new policies went into effect for how providers can bill for primary care services in a substance use disorder setting and how physicians can bill when offering MAT services.

To learn more about these policies, review:

What is a hub and spoke network?

Hub and spoke networks support collaborative, tiered levels of psychosocial and medical care to address OUD. They provide coordinated care within geographic regions led by a hub agency that is supported by five or more contracted behavioral health treatment, primary care, wraparound or referral agencies (spokes).

Where are these networks located?

There are currently six hub and spoke networks in western Washington.

  • Cascade Medical Advantage
  • Harborview Medical Center
  • Lifeline Connection
  • Northwest Integrated Health
  • Peninsula Community Health Services
  • Valley Cities

For full details on both hub and spoke facilities, view the hub and spoke directory.
