N675 Remark Code: Injured Party Must Send More Info

N675 means the carrier needs additional information from the injured party, the patient, before it can process the bill. The missing item is typically something only the claimant can provide, such as an application, statement, or authorization.

Code: N675 (RARC N675)
Status: Active In use since July 15, 2013.
Code set: Remittance Advice Remark Codes (RARC)
Group codes: CO (Contractual Obligation): Payment is held or denied pending the claimant's information. It is not yet a patient balance; the bill may be reconsidered once the information arrives.
PR (Patient Responsibility): Some carriers use PR here to show the claimant's non-response is the reason for non-payment. Check state rules before billing the patient.
Official description: Additional information is required from the injured party.

What N675 means

On auto, liability, and workers’ compensation claims, the injured person has obligations of their own: filing an application for benefits, giving a statement, signing authorizations to release records, or answering the carrier’s questions. Until they do, the carrier may not pay anyone, including the providers treating them.

N675 tells you your bill is stuck behind that. Your claim may be complete; the missing piece belongs to the claimant.

Common examples

The carrier sent the claimant an application or questionnaire that hasn’t been returned.
The carrier needs a recorded statement about how the accident happened.
A signed medical records authorization is missing.
Proof of identity, residence, or employment information is outstanding.
The claimant hasn’t responded to requests from the adjuster.

What to do

Call the adjuster to find out exactly what is missing and the deadline.
Contact the patient and explain what the carrier needs, how to send it, and why it affects their bills.
Document your outreach in the account notes, including dates and who you spoke to.
Follow up with the carrier after the patient says they’ve responded, and ask for the bill to be reprocessed.
Move to another payer if the claim is ultimately denied, such as the patient’s health plan with the carrier’s denial attached, as state law and your agreements allow.

How to prevent it

At the first visit for an injury case, ask the patient whether they’ve reported the claim and completed the carrier’s paperwork, and give them the adjuster’s contact. A short checklist for patients explaining their responsibilities in auto and work injury claims can prevent many N675 delays.

N675 FAQ

Can the provider send the information instead?

Usually not. The carrier needs the claimant's own statement, signature, or forms. The provider can help by telling the patient what's needed and whom to contact.

How long does the patient have to respond?

The carrier or state rules set the deadlines. Ask the adjuster so you can tell the patient and plan your follow-up.

What if the patient never responds?

The carrier may deny the claim. You may then bill the patient's health plan with the carrier's denial, or the patient, depending on state law and your financial policy.
