National Provider Identifier

Regence requires your NPI number be entered on all electronic claims. We will continue to accept your Regence provider number, in addition to the NPI, until further notice.  All electronic claims require both your NPI and tax identification number for accurate payment processing.

1. Obtain your National Provider Identifier (NPI)
If you have not applied for your NPI or if you are an Organizational provider and you need assistance, Centers for Medicare & Medicaid Services offers sub-part enumeration guidelines and many other NPI-related resources.

2. Submit your NPI to Regence

  • Use our online form:
    • Type 1 providers (physicians, dentists and all sole proprietors who are individuals eligible for only one NPI)
    • Type 2 providers (organizations such as physician groups, hospitals, nursing homes, and corporations which may have "subparts" that need their own NPIs).
  • Call your provider consultant to report your NPI
  • Send your NPI via standard mail to:
    Regence BlueShield                                        
    Provider Network Management      
    PO Box 21267 M/S 916
