Health Care Market Oversight

Through the Health Care Market Oversight (HCMO) program, the Oregon Health Authority (OHA) reviews proposed business deals to make sure they will help – and not hurt – Oregon's shared goals of health equity, lower consumer costs, increased access, and better care. The program applies to mergers, acquisitions, and other business deals that involve health care entities and meet certain criteria.

About the Program

In 2021, the Oregon Legislature passed HB 2362 to oversee health care consolidation, creating the Health Care Market Oversight (HCMO) program. This law directs the Oregon Health Authority (OHA) to review business deals involving health care entities, such as hospitals, health insurance companies, and provider groups. The HCMO program launched March 1, 2022 and aims to: 

  • Promote transparency: Track and publicly post notices when health care transactions occur. Communities will know about planned transactions.
  • Support statewide priorities: Ensure that health care consolidation in Oregon supports statewide goals related to health equity, lower costs, increased access, and better quality.
  • Monitor impacts: Analyze the type, number, and frequency of transactions, and study how transactions impact people in Oregon. OHA will produce statewide reports on the impacts of health care consolidation.
