Remark code N291 indicates an issue with a secondary identifier for the rendering provider; it's either missing, incomplete, or invalid.
Remark code N291 indicates that the claim submitted lacks a necessary secondary identifier for the rendering provider, or the information provided is either incomplete or invalid. This secondary identifier could be a taxonomy code, a unique provider identification number, or another type of identifier required by the payer. To resolve this issue, the healthcare provider must review the claim, correct the secondary identifier information for the rendering provider, and resubmit the claim for processing.
Common causes of code N291 are:
1. The secondary identifier field for the rendering provider is left blank on the claim form.
2. An incorrect secondary identifier, such as a taxonomy code or unique provider identification number (UPIN), is provided for the rendering provider.
3. The submitted secondary identifier does not match the information on file with the payer.
4. The claim form is missing required qualifiers that indicate the type of secondary identifier being used.
5. The secondary identifier is not applicable or not required for the specific payer, yet it was either included incorrectly or its absence was not properly justified.
6. The claim was submitted with outdated or expired information for the rendering provider's secondary identifier.
7. There is a mismatch between the rendering provider's primary identifier (such as NPI) and the secondary identifier on the claim.
8. The secondary identifier is not properly formatted according to the payer's specifications or industry standards.
Ways to mitigate code N291 include implementing a comprehensive verification process for all provider information before claim submission. This process should include double-checking the rendering provider's National Provider Identifier (NPI) and any other required secondary identifiers to ensure they are present and accurately recorded in the billing system. Regularly updating and validating provider databases, as well as training staff on the importance of complete and accurate data entry, can also help prevent this code. Additionally, using automated software that flags missing or invalid information can catch errors before claims are submitted.
The steps to address code N291 involve a thorough review of the claim to identify the missing or incorrect information. First, verify the rendering provider's information on the claim, ensuring that all required identifiers, such as the National Provider Identifier (NPI) or any applicable secondary identifiers, are present and accurately entered. If the secondary identifier is missing, obtain the correct information from the provider's records or credentialing documents. Once the correct information is gathered, update the claim with the accurate secondary identifier and resubmit it to the payer. It's also advisable to check if there have been any recent changes in the provider's credentials that may not have been updated in the billing system, and to ensure that all future claims include the complete and correct provider identifiers to prevent reoccurrence of this issue.
