N629 Remark Code: Unrequested Reports Not Payable

N629 means the payer did not request the reviews, documentation, notes, summaries, reports, or charts you billed for, so it will not pay for them. Report charges are typically payable only when the payer asked for the document.

What N629 means

Some injury payers pay separately for narrative reports, record reviews, and similar work, but only when they ask for it. N629 says the payer has no request on file for the document or review you billed, so it won’t pay the charge.

This remark is common on workers’ compensation and auto claims. It may appear with CARC P13, 96, or 234.

Common causes

  • A narrative report was prepared and billed without a request.
  • Record review time was billed on the provider’s own initiative.
  • An attorney or other party requested the report, but the bill went to the insurer.
  • The request was verbal and not documented.

What to do

  1. Look for the written request. If you have one from the payer, appeal with a copy.
  2. Bill the right party if someone else, such as an attorney, requested the report, according to your agreement with them and applicable rules.
  3. Write off the charge if no one requested it.

How to prevent it

Bill report and review codes only when you hold a written request from the party being billed. Ask adjusters to put requests in writing, and store them with the claim so they can be attached to the bill.

N629 FAQ

How is N629 different from N621?

N621 covers documents the jurisdiction requires. N629 covers documents the payer didn't ask for. In both cases the document charge isn't paid.

What proof shows a report was requested?

A written request from the adjuster or payer, such as a letter, email, or portal message, that identifies the report and the patient.

Does this include record review time?

The code covers reviews as well as reports. Reviewing outside records on your own initiative isn't paid separately by payers applying this rule.
