Procedure Code Lookup Tool

CHPW’s Procedure Code Lookup Tool lets you search for services by procedure code and line of business to determine:

  • If a prior authorization (PA) is required (indicates “yes” or “no”)
  • If there are PA conditions
  • If the service is a covered benefit (indicates “covered” or “not covered”)
  • The benefit requirements (limits, frequency, etc.)
  • Whether clinical review is needed
  • Specific clinical criteria CHPW applies and documentation needed for prior authorization (PA) review

Please note:

  • The Procedure Code Lookup Tool is not intended to replace the use of the Prior Authorization list, nor is the tool necessarily complete. Providers should only use this tool as a supplement to and after first consulting the Prior Authorization lists.
  • If you select the Washington Apple Health Behavioral Health Services Only (BHSO) plan, the lookup tool provides PA and coverage information for behavioral health benefits only. Medical benefits for BHSO members are not administered by CHPW.
  • For Medicare Advantage, refer to local coverage determinations (LCD) and/or national coverage determinations (NCD) for full clinical criteria.
  • For additional benefit information, see the Member Benefit Grids:
