RARCs (Remittance Advice Remark Codes) provide the specific reason detail alongside CARC 151 on the 835 electronic remittance. These are the RARCs seen most often with this CARC.

RARCMeaning
M3 Equipment is the same or similar to equipment already being used.
M25 The information furnished does not substantiate the need for this level of service. If you believe the service should have been fully covered as billed, or if you did not know and could not reasonably have been expected to know that we would not pay for this level of service, or if you notified the patient in writing in advance that we would not pay for this level of service and he/she agreed in writing to pay, ask us to review your claim within 120 days of the date of this notice. If you do not request an appeal, we will, upon application from the patient, reimburse him/her for the amount you have collected from him/her in excess of any deductible and coinsurance amounts. We will recover the reimbursement from you as an overpayment.
M69 Paid at the regular rate as you did not submit documentation to justify the modified procedure code.
M86 Service denied because payment already made for same/similar procedure within set time frame.
N10 Adjustment based on the findings of a review organization/professional consult/manual adjudication/medical advisor/dental advisor/peer review.
N115 This decision was based on a Local Coverage Determination (LCD). An LCD provides a guide to assist in determining whether a particular item or service is covered. A copy of this policy is available at www.cms.gov/mcd, or if you do not have web access, you may contact the contractor to request a copy of the LCD.
N130 Consult plan benefit documents/guidelines for information about restrictions for this service.
N206 The supporting documentation does not match the information sent on the claim.
