Unofficial reference. This is our own plain-English explanation, not the official code text. Payer rules differ. Verify with the payer and the official X12 code list. AlphaPrefix is not affiliated with X12, CMS or any payer. Data last updated Nov 11, 2026.

What N570 means

The payer is missing or cannot use credentialing information for the provider, so the claim could not be processed.

N570 points to the provider's file with the payer, not the claim itself. Credentialing or enrollment data such as license, specialty or effective date is missing, expired or does not match.

It typically supports a reason code about provider eligibility. Claims usually need to be reprocessed once credentialing is complete.

Common causes

• The provider began seeing patients before credentialing was approved.
• Re-credentialing was not completed by the payer's deadline.
• The service date is before the provider's effective date with the payer.

What to do next

1. Check the provider's credentialing status and effective date with the payer.
2. Send any missing credentialing documents to the payer's credentialing department.
3. Ask for reprocessing of held or denied claims once credentialing is approved.
4. Track re-credentialing dates for every provider.
