National Provider Identifier (NPI)

Per the federal regulation, all standard transactions (such as electronic claims, benefits and eligibility inquiries, etc.) you conduct with BCBSIL and other payers must include your NPI as your primary provider identification number

If you are a participating provider with BCBSIL, you should already have a Type 1 Individual and/or a Type 2 Organizational NPI on file with us.

  • To check your details on file with the National Plan & Provider Enumeration System (NPPES), view the NPI Registry.
  • Compare your NPPES information to your information on the BCBSIL Provider Finder to ensure all data matches and is accurate and up-to-date.
  • If you need to update your existing NPI information, or make any other changes to your provider file, use our online Information Change Request form.

Claim filing reminders:

  • BCBSIL requires use of the NPI on paper and electronic claims.
  • The NPI does not replace your Federal Taxpayer Identification Number (TIN). Your TIN will continue to be required on all claims for tax reporting purposes.
  • You should also include your taxonomy code on claims, as reported to NPPES when you applied for your NPI.

If you have questions or need additional information regarding the NPI Standard, visit the Centers for Medicare and Medicaid Services (CMS) website.
