Frequently asked questions — RARC N620
What does RARC N620 mean?
RARC N620 is an X12 Remittance Advice Remark Code. The official X12 definition is: "This payer does not cover items and services furnished to an individual while they are in custody under a penal authority, unless under State or local law, the individual is personally liable for the cost of his or her health care while incarcerated and the State or local government pursues such debt in the same way and with the same vigor as any other debt." It is supplemental to a Claim Adjustment Reason Code (CARC) on the same 835 line.
Which CARC is paired with RARC N620?
RARC N620 is most commonly paired with CARC 258. The CARC is the financial adjustment reason; the RARC is the informational remark. Fix the paired CARC first — the RARC usually clears with the corrected claim.
How do I resolve a RARC N620 remark on a remit?
Start from the root cause: Patient incarcerated; plan excludes unless state-debt exception applies. First step: Route to correctional payer or state debt program. Because RARCs are supplemental, the resolution is almost always to address the paired CARC rather than appeal the RARC alone.
Where does RARC N620 appear on the 835 ERA?
RARC N620 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 N620 the same as ICD-10 code N620?
No. RARC N620 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.
