What MA46 means

After a claim is processed, you might send additional records, an explanation, or corrected data to try to change the result. MA46 tells you the payer did look at it, but the outcome is the same and no more money is coming.

Unlike a denial for missing information, MA46 is not asking for anything. It closes the loop on your submission.

What to do

  1. Read the paired CARC to see which reason still applies.
  2. Review what you sent against the payer’s reason. Identify whether key evidence was missing.
  3. Decide on next steps. If you still disagree and have new support, pursue the next appeal level within its deadline.
  4. Close the balance if the decision is correct. Bill the patient only for PR amounts.
  5. Update your processes to prevent the original issue.

Keeping track of which types of submissions succeed helps you prioritise. See CARC and RARC denial analysis.

MA46 FAQ

Does MA46 mean my appeal was denied?

It means the new information did not produce more payment. Whether that was a reopening, a reconsideration, or an appeal depends on how you submitted it. Check any accompanying letter.

Can I go to the next appeal level?

Often yes, if you have not exhausted your appeal rights. Check the payer's process and deadlines for the next level.

Should I resubmit the same information?

No. Sending it again rarely changes the result. Consider what additional evidence would address the payer's reason.
