Remark code N21 indicates that an item on a claim has been split into multiple lines for faster processing.
Remark code N21 indicates that the submitted claim's line item has been divided into separate lines to facilitate faster processing and handling. This action may have been taken by the payer to address specific billing nuances or to conform to their internal claims processing procedures. Healthcare providers should review the claim details to ensure that the separation aligns with the services provided and that it does not affect the reimbursement process.
Common causes of code N21 are related to the billing process where a single service or item that was originally billed on one line has been divided into separate lines by the payer. This could be due to the payer's system requirements for processing certain services or items, or because different components of the service need to be adjudicated separately. It may also occur if the billing format did not match the payer's expectations, necessitating a breakdown of the service into more granular detail for claims processing purposes.
Ways to mitigate code N21 include ensuring that billing items are grouped correctly according to the payer's guidelines before submission. Review the payer's billing instructions for specific services to understand how they prefer items to be listed on the claim. Utilize billing software that can flag potential separations before the claim is sent, and train staff to recognize services that commonly require separation so they can address these preemptively. Regularly update your billing practices to align with any changes in payer requirements to minimize the need for line item separation after submission.
The steps to address code N21 involve reviewing the Explanation of Benefits (EOB) or Electronic Remittance Advice (ERA) to identify how the line item was divided. It's important to verify that the separation of the line item into multiple lines reflects the services provided accurately. If the separation is correct, adjust your billing records to match the EOB or ERA for proper tracking and reconciliation. Should there be discrepancies, prepare and submit a corrected claim with the appropriate documentation to support the billed services. Additionally, ensure that your billing system can accommodate such splits in the future to prevent delays in payment processing. Keep a record of the occurrence to identify any patterns that may require a review of your coding practices.
