N735 Remark Code (Deactivated): Adjusted Without Records

N735 meant the payer made an adjustment without reviewing the medical or dental record, because the records it requested were not received or not received timely. X12 deactivated it without naming a replacement.

X12 deactivated RARCN735 on January 1, 2016. Payers should no longer use it on new remittances, but it can still appear on older ERAs, corrected claims, and appeals.

What N735 meant

Remark N735 described a payer acting on a claim without the records it had asked for. Because the documents never arrived, or arrived after the deadline, the payer reduced or denied the claim without looking at the clinical record. The decision reflected missing paperwork, not a judgment about the care.

What replaced it

X12 did not name a successor, and the remark was active for only a short time. The same situation is typically reported now with CARC CO-226, and remark N366 tells providers the claim can be reopened if the requested information is sent in time. The earlier remark N102 covered denials of this kind.

If you still see N735

It appears only in older claims. Locate the original records request, send the complete records through the payer’s reopening or appeal process, and track confirmation of receipt.

CO-226 (Information requested from the Billing/Rendering Provider was not provided or not provided timely or was insufficient/incomplete.): Information requested from the billing or rendering provider was not provided, not provided timely, or was insufficient.
N366 (Requested information not provided.): Requested information not provided; the claim will be reopened if the information is submitted within the stated time.
N102Deactivated (This claim has been denied without reviewing the medical/dental record because the requested records were not received or were not received timely.): An earlier, also deactivated remark for claims denied without record review.

N735 FAQ

How is N735 different from N102?

N102 described a denial without record review. N735 used the broader word adjustment, covering reductions as well as full denials, for the same missing-records situation.

Is the adjustment final?

Usually not, if you act within the payer's reopening or appeal window and supply the records.
