Summary
Oregon Health Authority removed the December 31, 2025 supplemental OHP dental codes list due to technical inconsistencies with Oregon Administrative Rules (OARs) effective January 1, 2026. Providers must rely solely on Division 123 OARs for dental benefit coverage and billing guidance until a corrected reference document is posted in the coming weeks.
Action Required
Immediately: Stop using the December 31, 2025 'Oregon Medicaid Covered Dental Services' list for billing decisions. Billing teams must reference Division 123 OARs in Chapter 410 and HERC guideline notes as the sole authoritative source for OHP dental benefit coverage, frequency, and limitations. Monitor for the corrected supplemental code list to be posted in coming weeks at oregon.gov/OHA.
