N21Remark Code (RARC)ActiveInformational Alert
N21 Remark Code - Alert for Line Item Separation
The N21 remark code indicates that your line item has been separated into multiple lines on the remittance advice to facilitate quicker processing. This alert does not indicate any denial or adjustment; rather, it serves to inform you about the handling of your claim.
What This Alert Tells You
The N21 remark is an informational alert that appears independently and is not associated with any specific adjustment or denial reason code. It is meant to clarify the format of the remittance advice for the provider.
Common Scenarios
1You receive an 835 remittance for a complex procedure that was billed as a single line item, but it appears as multiple line items in the payment details.
→ In this case, the N21 remark explains that the separation into multiple lines is intentional to improve processing efficiency, not a reflection of any issues with the claim.
2An ERA shows a claim with several services billed together, but they are listed separately on the remittance advice with the N21 remark code.
→ The N21 alert is simply indicating that the services have been broken out into individual line items for clarity, allowing for easier review and reconciliation.
3While reviewing a remittance advice, you notice the N21 code next to a line item that was expected to be paid as one lump sum.
→ The presence of the N21 remark clarifies that the payer has chosen to list the payment in a segmented manner for expedited handling, which does not affect the payment amount.
