What MA67 means

MA67 is an alert. It tells you this claim is not new: the payer already processed it once and is now reporting a correction. The correction may come from your corrected claim, a reopening, the payer’s own audit, or a system fix. In the 835, this often shows up as a reversal of the original claim followed by a corrected claim record.

What to do

  1. Find the original payment in your system using the payer claim number.
  2. Net the reversal and the new line. The true change is the difference between the two, not the corrected amount alone.
  3. Update patient responsibility if deductible, coinsurance, or copay changed.
  4. Watch for offsets. If the correction lowered payment, the payer may recover the overpaid amount from a future remittance.
  5. Dispute only if needed. If the corrected result conflicts with your contract or documentation, contact the payer or use its appeal process.

Posting corrections as new payments inflates collections and hides recoupments. Reviewing reversals across remittances, for example with an ERA Analyzer, makes them easier to spot.

Codes that may appear with MA67

  • CO-129 (Prior processing information appears incorrect.): Prior processing information was incorrect, which is the typical reason a corrected claim appears.
  • CO-45 (Charge exceeds fee schedule/maximum allowable or contracted/legislated fee arrangement.): The corrected line often reprices the service, reporting a new fee schedule adjustment.
  • MA62 (Alert: This is a telephone review decision.): Identifies that the change was made through a telephone review specifically.
  • MA74 (Alert: This payment replaces an earlier payment for this claim that was either lost, damaged or returned.): A replacement payment for a lost or returned check, not a change to the claim itself.
  • N10 (Adjustment based on the findings of a review organization/professional consult/manual adjudication/medical advisor/dental advisor/peer review.): Explains that a review organization or manual adjudication drove the adjustment.

MA67 FAQ

Why does my ERA show a reversal and a new line?

Payers often correct a claim by reversing the original payment and reprocessing it. MA67 flags the corrected result so you can match the two.

Do I need to resubmit anything?

Usually not. The payer has already reprocessed the claim. Only act if the corrected amounts still look wrong.

Can a correction reduce my payment?

Yes. Corrections can go either way, and a lower result may create an offset against future payments.
