Funding for the evaluation of Washington State’s Medicaid Transformation Project (MTP) is from the U.S. Department of Health and Human Services, Centers for Medicare & Medicaid Services, Center for Medicare and Medicaid Innovation. The Center for Health Systems Effectiveness (CHSE) at Oregon Health & Science University (OHSU) was selected by the Washington State Health Care Authority (HCA) as the independent external evaluator for the MTP evaluation. CHSE will use a list of provider organizations generated from the WA-APCD to conduct surveys that are part of the evaluation.
