What N622 means

For injury claims, the date of injury or accident determines which policy applies and whether coverage exists. N622 says this date is the reason for the denial. Common scenarios are an injury date that falls outside the policy period or a date that doesn’t match what the insurer has on file.

It is used mostly on workers’ compensation and auto claims and commonly appears with CARC P6, 26, or 27.

Common causes

  • Keying error in box 14 of the CMS-1500 or the equivalent field.
  • The first visit date was entered as the injury date.
  • A different accident’s date was used for a patient with more than one claim.
  • The policy wasn’t active on the injury date, for example it started later or had lapsed.

How to fix it

  1. Compare dates in your records, the accident or first report of injury, and the payer’s claim.
  2. If your date was wrong, submit a corrected claim with resubmission code 7 and the accurate injury date.
  3. If the payer’s date is wrong, send supporting documents and ask it to correct its file.
  4. If the policy truly didn’t cover that date, find the correct carrier or bill the patient’s health insurance.

How to prevent it

Take the injury date from the carrier’s claim acknowledgment rather than from memory, and store it on the case so every bill uses the same date. Claims Validator can check claims before submission to catch a missing or inconsistent injury date.

N622 FAQ

Where does the date of injury go on a CMS-1500?

Box 14 holds the date of current illness, injury, or pregnancy, with a qualifier. Box 10 flags whether the condition relates to employment or an accident.

What if the patient had two accidents?

Each accident is usually a separate claim with its own number and date. Make sure the bill uses the claim that matches the injury being treated.

Can the payer's date be wrong?

Yes. If the payer's record doesn't match the accident report or first treatment record, send those documents and ask for a correction.
