Frequently asked questions — RARC N220
What does RARC N220 mean?
RARC N220 is an X12 Remittance Advice Remark Code. The official X12 definition is: "Alert: See the payer's web site or contact the payer's Customer Service department to obtain forms and instructions for filing a provider dispute." It is supplemental to a Claim Adjustment Reason Code (CARC) on the same 835 line.
How do I resolve a RARC N220 remark on a remit?
Start from the root cause: Informational pointer to dispute process. First step: Follow the payer's dispute instructions. Because RARCs are supplemental, the resolution is almost always to address the paired CARC rather than appeal the RARC alone.
Where does RARC N220 appear on the 835 ERA?
RARC N220 is carried on the 835 Loop 2110 LQ segment alongside the CARC in the CAS segment of the same service line. The code and its X12 description also print on the paper EOB in the "Remark Code" or "Remark" column next to the corresponding denial or adjustment reason.
Is RARC N220 the same as ICD-10 code N220?
No. RARC N220 is a remittance-advice remark code published by X12 and carried on the 835. Any ICD-10 code with the same letters and digits is a diagnosis code on the 837 HI segment — a completely different code set maintained by the WHO/CMS. Use the transaction context (835 = RARC; 837 = ICD-10) to disambiguate.
