What N594 means

In no-fault auto systems and some other injury programs, the injured person must formally apply for benefits before the insurer will pay anyone. N594 says the insurer has no completed application from the injured party for this loss. Until one is filed, your bills cannot be paid, even if everything on them is correct.

It is typically paired with CARC 227, P21, or P6.

Common causes

  • The patient assumed the provider or another driver would handle the claim.
  • The application was started but incomplete or unsigned.
  • The patient filed with a different insurer than the one you billed.
  • The application was filed under a different claim number or name.

What to do

  1. Confirm with the adjuster what is missing and the deadline.
  2. Give the patient the application or the insurer’s contact information, and explain why it matters.
  3. Hold bills to that carrier until the application is on file, then ask whether prior bills will be reprocessed or need to be resubmitted.
  4. Watch deadlines. If the application deadline passes, discuss other coverage options with the patient.

How to prevent it

Add a simple check to accident intake: “Have you filed an application for benefits with your auto insurer?” If not, give the patient the form or the carrier’s phone number on the spot, and record the claim number once it is issued.

N594 FAQ

What is an Application for Benefits?

A form the injured person files with the insurer to open a claim, often called a no-fault application in some states. It gives the insurer basic facts about the accident and injuries.

Can the provider fill it out?

It must come from the injured person, though providers often help by giving patients the form and the insurer's contact information.

Is there a deadline for the application?

Many states and policies set one. Missing it can jeopardize benefits, so the patient should file as soon as possible.
