Frequently Asked Questions

Question

Response

Have you implemented the NPI?

Yes, you are now required to submit an NPI on all electronic claims, with or without your Regence provider number. We will notify you when the Regence identifier will no longer be accepted.

Note: Hospitals, other facilities and medical groups submitting professional claims either electronically or on a CMS-1500 should continue submitting their Regence identifier in addition to their NPI to facilitate proper payment assignment. We will notify you when this is no longer necessary.
Do I still need to include my tax identification (ID) number on my claims submissions? Yes, the NPI does not replace the tax ID number. Your tax ID number is a critical element that helps us correctly process your payments.
Are NPIs validated as part of the adjudication process or claims submission process? Yes, for electronic claims submissions, the NPI is validated to ensure formatting of the NPI is correct. For adjudication, the NPI on the claim is validated against the NPI information submitted to Regence by the provider.
How can I be sure you have my correct NPI?

The NPI on file is printed on your payment voucher.

  • Please verify the NPI on your voucher is correct.
  • If you think it is incorrect, please contact Provider Services immediately.
Are taxonomy codes required to adjudicate claims? Regence does not require the use of taxonomy codes.
How do you process same provider/multiple locations claims/remittance advices? Regence continues to process and distribute payments using processes currently in place.
Do you have subpart requirements? No. See CMS guidelines related to subparts (PDF) for more information.
Do you require new Trading Partner Agreements? No.
Do you require the NPI on paper-based transactions? While we are not requiring the NPI on paper-based transactions, we do recommend that the NPI be included on all transactions whether submitted electronically or on paper.
Do you require providers to update you in addition to the Enumerator? Yes, you must notify us of your NPI prior to submission of claims-based transactions.
