What N704 means

An alert that this decision is not appealable, though the claim can be resubmitted if corrected information applies.

N704 is an informational alert that comes with a decision such as a rejection for incomplete data. An appeal will not be accepted, but a corrected or new claim with better information may be.

The reason code on the line shows what was wrong, and that tells you what to fix.

Common causes

• The claim was denied for data that a corrected claim can supply.
• The payer routes this type of decision to resubmission instead of appeal.
• A billing error, not a medical judgment, caused the denial.

What to do next

1. Read the reason code and other remark codes to find what needs correcting.
2. Fix the claim data and resubmit using the payer's corrected claim rules.
3. Do not send an appeal, as it will usually be returned.
4. Watch the filing deadline for the corrected submission.
