What MA67 means

An informational alert that this remittance line corrects a claim processed earlier, so posting must reflect both.

This remark tells you the payer is adjusting a claim it already processed. You will often see a reversal of the original payment and a new payment on the same or a later remittance.

It is an alert, not a denial. Match the correction to the original claim so the account balance is posted correctly.

Common causes

• You sent a corrected or replacement claim.
• The payer reopened the claim on its own to fix a pricing or processing error.
• A coverage update changed how the original claim should have been paid.

What to do next

1. Find the original claim and its posting on the account.
2. Post the reversal and the new payment together so the balance is accurate.
3. Check whether the correction created a credit or a new balance to follow up.
