CN describes an amendment to the existing contract. The tradeline continues; it does not close and reopen.
CN is the key distinction against AS: a modification amends the loan in place, while a refinance replaces it with a new obligation and a new tradeline.
CN does NOT mean the debt was reduced, although a modification may change what the borrower pays each month.
CN does NOT cure a prior delinquency by itself. A modification changes future obligations; the history before it stays as reported.
A modification usually changes something measurable. If Scheduled Monthly Payment, Terms Duration, and Terms Frequency all stayed identical, check whether a modification actually occurred.

1A mortgage servicer completes a permanent loan modification that lowers the rate and extends the term after a trial period.
2A lender permanently re-amortizes a consumer loan following a hardship, changing the monthly payment and maturity.
3A credit union restructures a member's auto loan with a new maturity rather than writing a new contract.
4A servicer converts a temporary interest-only workout into a permanent modified payment schedule.

Report CN from the cycle the modification takes effect, and update the terms fields in the same record.
Do not use CN for a temporary arrangement. A pause is B or C, a deferral is AI, an interest-only workout is AC, and a catch-up plan is AU.
Do not use CN for a refinance. AS marks the closing tradeline and the replacement loan reports separately.
Do not restart the tradeline. Date Opened, the payment history, and any Date of First Delinquency carry forward.
Keep the modified terms and the reported terms in sync every cycle afterward.

A file can be structurally valid and still be wrong. These are the cross-field conditions Special Comment Code CN has to satisfy.

Scheduled Monthly Payment, Terms Duration, and Terms Frequency should be updated in the same record to the modified values.
Date Opened must NOT change. A modification is not a new account.
Date of First Delinquency stays anchored to the original delinquency if one occurred before the modification.
Current Balance may change if arrears were capitalized into the principal; that increase should be traceable to the modification.
Account Status reports the account's real condition after modification, which is commonly current once the borrower is performing under the new terms.
