MA07 Remark Code: Claim Forwarded to Medicaid

MA07 is an informational alert. It tells you the claim information has also been sent to Medicaid for review, usually through Medicare's crossover process, so Medicaid can consider any secondary payment it owes.

What MA07 means

For patients who have both Medicare and Medicaid, Medicare often sends the processed claim on to the state Medicaid program automatically. MA07 confirms this happened. It is an alert, so there is nothing wrong with the claim; it simply tells you where the remaining balance is headed.

The amounts on the line, usually deductible or coinsurance, are what Medicaid will consider. Hold off on billing the patient for them. Patients with both coverages are often protected from cost-sharing billing, depending on their eligibility category and your participation status.

What to do

  1. Post the Medicare payment and mark the remaining balance as pending with Medicaid.
  2. Wait for the Medicaid remittance before taking further action on the balance.
  3. Follow up if nothing arrives. Confirm with Medicaid that the crossover was received before submitting a claim directly.
  4. Check billing rules before sending any statement to a dual-eligible patient.

More on handling multiple payers is in eligibility and coordination of benefits denials.

Codes that may appear with MA07

  • PR-1 (Deductible Amount): A deductible amount that Medicaid may review for secondary payment.
  • PR-2 (Coinsurance Amount): Coinsurance that the crossover lets Medicaid consider.
  • MA18 (Alert: The claim information is also being forwarded to the patient's supplemental insurer.): The claim was forwarded to a supplemental insurer instead of Medicaid.
  • MA08 (Alert: Claim information was not forwarded because the supplemental coverage is not with a Medigap plan, or you do not participate in Medicare.): The claim was not forwarded because the supplemental coverage is not a Medigap plan or you do not participate.
  • MA19 (Alert: Information was not sent to the Medigap insurer due to incorrect/invalid information you submitted concerning that insurer.): The claim was not sent to the Medigap insurer because the insurer information was incorrect.

MA07 FAQ

Do I need to bill Medicaid myself?

Usually not right away. Allow time for Medicaid to process the crossover. If nothing arrives within your normal follow-up window, check with Medicaid before billing it directly to avoid a duplicate.

Does MA07 mean Medicaid will pay?

No. It only means Medicaid received the claim information. Medicaid applies its own rules and may pay part, all, or none of the remaining amount.

Is MA07 an error I need to correct?

No. It confirms a routing step. Act only on the reason codes on the claim, not on MA07 itself.
