What N938 means

Normally a denied claim waits for you to act. N938 reverses that. The payer is telling you it has identified something to fix and will rerun the claim itself. Your job is to wait and track, not to resubmit.

What to do

Do not send a corrected or new claim. A resubmission may be denied as a duplicate. See duplicate claim denials.
Hold the balance open instead of writing it off or billing the patient.
Set a follow-up date based on the payer’s normal reprocessing timeframe.
Check claim status if nothing arrives by then, and ask the payer for an expected date.

N938 FAQ

Why would a payer reprocess automatically?

Common reasons include a payer-side system or pricing error, a fee schedule update, or a pending eligibility or provider record correction. The payer fixes the issue and reruns affected claims.

How long should I wait?

It depends on the payer. Note the remittance date, and check claim status if reprocessing has not appeared within the payer's usual cycle.

What if the reprocessed claim is still wrong?

Then treat the new remittance like any other decision, and correct, resubmit, or appeal based on its codes.
