📋What Does N60 Mean? A Full Explanation

Denial code N60 is a Claim Adjustment Reason Code (CARC) used on the 835 electronic remittance advice and Explanation of Benefits (EOB) to communicate why a claim or service line was adjusted from the billed amount. This code is standardized by X12 and used consistently by Medicare, Medicaid, and commercial payers across all HIPAA-compliant transactions.

When this code appears on your remittance, it signals a specific issue that caused the payer to pay a different amount than billed. Identifying the root cause tied to this code is the first step toward correcting the claim, resubmitting, or filing an appeal to recover lost reimbursement.

⚠️Common Reasons You Received Denial Code N60

→Missing, invalid, or incomplete information on the claim
→Billing code mismatch or modifier inconsistency
→Service not covered under the patient's plan on the date of service
→Authorization or referral not obtained prior to treatment
→Duplicate claim submission or previously adjudicated service

📨How to Appeal a N60 Claim Denial Effectively

Appealing a N60 denial requires a timely, well-documented response. Most payers require appeals within 30 to 180 days of the remittance date — missing this window typically results in a final denial. Start by reviewing the payer's provider manual for the specific appeal process and required forms.

Your appeal package should include a clear cover letter referencing the original claim number and denial date, corrected claim information if applicable, relevant medical records or clinical notes supporting medical necessity, and copies of the original claim and remittance advice. Submit via certified mail or the payer portal and retain confirmation of receipt.
