What N570 means

Before paying, most payers confirm that the provider on a claim has been credentialed: licenses, certifications, and other qualifications reviewed and approved. N570 says something in that credentialing data is missing, incomplete, or invalid. The problem is typically in the payer’s provider file, not in a claim field you can simply correct.

It usually appears with CARC B7 (provider not certified or eligible on the date of service), CARC 16, or CARC 185.

Common causes

  • Credentialing is still in process or was never completed for this provider.
  • A license or certification expired and the updated copy was not sent to the payer.
  • The provider was credentialed individually but not linked to the billing group or location.
  • Recredentialing lapsed because the payer’s request went unanswered.
  • A provider on the claim, such as the rendering provider, is not the one who was credentialed, for example a new clinician billing under a colleague’s setup.

How to fix it

  1. Call the payer’s provider services and ask exactly which credentialing element is missing or invalid.
  2. Submit the missing items and confirm the effective date once approved.
  3. Resubmit held or denied claims for dates on or after the effective date. Use resubmission code 7 for claims that were already processed, unless the payer asks for new claims.
  4. Appeal if credentialing was active on the date of service and the payer’s file was wrong.

How to prevent it

Track license and certification expiration dates and payer recredentialing cycles in one place, and confirm every new provider’s credentialing and group linkage before scheduling them for that payer. See provider enrollment denials.

N570 FAQ

Is N570 about the claim or the payer's file?

Usually the payer's file. The credentialing record may be incomplete, pending, or not linked to the group, even if the claim itself is filled out correctly.

Can I bill for services while credentialing is pending?

Some payers allow retroactive effective dates and others do not. Ask the payer what date credentialing will be effective before holding or submitting claims.

Who fixes credentialing data?

Whoever manages enrollment for the practice, working with the payer's credentialing or provider data team.
