What MA62 means

MA62 is an alert, not a reason for nonpayment. It tells you that the decision reflected on this remittance line came out of a telephone review. With Medicare contractors this usually means a telephone reopening, where a biller calls the contractor to fix a minor error such as a wrong date, a missing modifier, or a keying mistake, and the contractor reprocesses the claim on the spot.

Because the review happened by phone, there may be no separate written decision letter. The remittance advice carrying MA62 becomes your record of what changed.

What to do

  1. Compare the new line to the original. Check the allowed amount, payment, and adjustment codes against the first remittance and your phone call notes.
  2. Post the difference. If the reprocessing produced additional payment, post it against the original claim rather than as a new charge.
  3. Record the call reference number with the claim so the history is easy to follow if questions come up later.
  4. Escalate in writing if needed. If the phone review did not resolve the issue, or the question involves medical judgment, request a written redetermination instead. Phone reviews are not a substitute for a formal appeal.

Keep an eye on which errors you keep fixing by phone. Recurring phone corrections point to a front-end issue that a pre-submission check could catch; see how to read CARC and RARC codes together.

Codes that may appear with MA62

  • CO-16 (Claim/service lacks information or has submission/billing error(s).): A claim previously adjusted for missing or invalid information may be corrected by phone and reprocessed with MA62.
  • CO-4 (The procedure code is inconsistent with the modifier used.): Modifier-related adjustments are a common subject of phone corrections, so the reprocessed line may show MA62.
  • MA67 (Alert: Correction to a prior claim.): A broader alert that the remittance reflects a correction to a prior claim, however it was requested.
  • N10 (Adjustment based on the findings of a review organization/professional consult/manual adjudication/medical advisor/dental advisor/peer review.): Points to a review organization or manual adjudication as the source of the decision, not a phone call.
  • MA01 (Alert: If you do not agree with what we approved for these services, you may appeal our decision.): Medicare's appeal-rights alert, which explains how to dispute a decision you still disagree with.

MA62 FAQ

Does MA62 mean my phone request was approved?

Not necessarily. MA62 only says a telephone review produced the decision. The CARC and payment amounts on the line show whether the outcome went your way.

What if I still disagree after a telephone review?

Phone reviews are generally limited to simple, clerical-type corrections. If you still disagree, use the payer's written redetermination or appeal process and its time limits.

Do I need to do anything when MA62 appears?

Only reconcile the payment. Match the reprocessed line to the original claim and your call notes, then post any change.
