What M54 means

The total charge on the claim is missing or does not add up to the sum of the line charges.

The payer checks that the claim total matches the line charges. This remark means the total was blank, zero, or did not equal the sum of the lines.

It usually comes with reason code 16. It is most often caused by a system or manual edit to the claim after the totals were calculated.

Common causes

• A line was added, removed or changed after the claim total was set.
• A rounding or formatting error in the claim file changed the total.
• The total charge field was left blank on a paper claim.

What to do next

1. Add up the line charges and compare them with the total on the claim.
2. Correct the total or the line charges in the billing system.
3. Resubmit the claim and check for clearinghouse edits that might catch this next time.
