Oregon is facing resistance to its attempt to overhaul a 30-year-old program that controls costs for the state's Medicaid-funded Oregon Health Plan. The Health Evidence Review Commission, a panel of experts, currently oversees the 'Prioritized List' that determines which care and services are covered. State officials want to make the commission just another advisory board and make major changes to the Prioritized List, but former Gov. John Kitzhaber, who helped create the program, warns this would 'add huge administrative costs and confusion to the system'.

Why it matters

The Prioritized List program is central to Oregon's managed care system for the Oregon Health Plan, which provides coverage for lower-income residents. Supporters say the public, evidence-based process helps stretch limited funding, while critics argue it impedes needed care. As the state faces budget cuts, the debate centers on whether the cost-control program should be preserved or overhauled.

The details

The Oregon Health Authority is backing legislation, House Bill 4003, that would make the Health Evidence Review Commission just another advisory board and make major changes to the Prioritized List it oversees. The agency has been working on this for nearly two years after a previous attempt to scrap the list failed. Rep. Rob Nosse says the changes are relatively minor, but Kitzhaber calls it a 'huge decision' that would 'overturn a process we've had in place for 30 years.' The rushed pace of the bill is also concerning to Kitzhaber, who says it's being done with last-minute amendments in a short legislative session.

  • The Prioritized List program was created 30 years ago.
  • The Oregon Health Authority has been working on changes to the program for nearly two years.
  • House Bill 4003 is scheduled for a House Health Care Committee hearing on Tuesday.
