Common RARC pairings

RARCs (Remittance Advice Remark Codes) provide the specific reason detail alongside CARC 234 on the 835 electronic remittance. These are the RARCs seen most often with this CARC.

RARCMeaning
M2 Not paid separately when the patient is an inpatient.
M14 No separate payment for an injection administered during an office visit, and no payment for a full office visit if the patient only received an injection.
M15 Separately billed services/tests have been bundled as they are considered components of the same procedure. Separate payment is not allowed.
M80 Not covered when performed during the same session/date as a previously processed service for the patient.
N20 Service not payable with other service rendered on the same date.
N67 Professional provider services not paid separately. Included in facility payment under a demonstration project. Apply to that facility for payment, or resubmit your claim if: the facility notifies you the patient was excluded from this demonstration; or if you furnished these services in another location on the date of the patient's admission or discharge from a demonstration hospital. If services were furnished in a facility not involved in the demonstration on the same date the patient was discharged from or admitted to a demonstration facility, you must report the provider ID number for the non-demonstration facility on the new claim.
N83 No appeal rights. Adjudicative decision based on the provisions of a demonstration project.
N122 Add-on code cannot be billed by itself.
