Alert: claim forwarded to Medicaid

What MA07 means

An informational alert that the claim information was also sent on to Medicaid for its review.

This remark appears on Medicare remittances for patients who also have Medicaid. It tells you the claim was passed along automatically so Medicaid can consider its share.

It is an alert, not a denial. You usually do not need to send a separate claim to Medicaid unless it does not respond in a reasonable time.

Common causes

• The patient has both Medicare and Medicaid coverage on file.
• A crossover arrangement exists between Medicare and the state Medicaid program.
• Medicare left a balance that Medicaid may cover.

What to do next

1. Note the crossover on the account so staff do not bill Medicaid twice.
2. Watch for the Medicaid payment or remittance within its normal processing time.
3. If nothing arrives, check claim status with Medicaid before sending a separate claim.
