Prioritized List of Health Services

Questions and Answers About the Prioritized List

For detailed information about the creation of the Prioritized List, see the Health Evidence Review Commission's (HERC) Brief History of Health Services Prioritization in Oregon or the biennial reports to the Oregon legislature on the HERC reports page.

The Oregon Health Evidence Review Commission (HERC) ranks health care condition and treatment pairs in order of clinical effectiveness and cost-effectiveness.

The Prioritized List emphasizes prevention and patient education. In general:

  • Treatments that help prevent illness are ranked higher than services that treat illness after it occurs.
  • OHP covers treatments that are ranked on a covered Prioritized List line for the client's reported medical condition.

Effective Jan. 1, 2022, OHP covers Prioritized List lines 1 through 472.

Use the following links on the HERC website. You can also subscribe to receive email notifications from HERC. HERC sends updates whenever Prioritized List information changes.

For OHA policies related to Prioritized List coverage or exclusions, see the General Rules, Oregon Health Plan rules, and the provider guidelines specific to your program.

To find out whether a specific procedure is potentially covered according to the Prioritized List, providers can use the HSC List inquiry on the Oregon Medicaid Provider Portal at www.or-medicaid.gov or call the OHP Code Pairing and Prioritized List Hotline at 800-336-6016.​
