Why does Medicaid say my claim is a duplicate?
A duplicate denial means Medicaid already has a claim for the same client, service and date. Georgia lists codes 5646, 5042 and 5048 for exact duplicates. No fix is needed. Search by client ID and date to find the paid claim, and call the state if you cannot find it.
Duplicate denials are usually good news in disguise. They often mean the first claim paid.
Georgia’s guidance says exact duplicates need no correction. You find the claim that was already paid and stop.
How to check:
- Search claim history by client ID, date of service and claim type.
- Find the paid claim and match it to your remittance.
- If you cannot find it, contact the state’s provider help desk.
Why duplicates happen:
- Someone resubmitted a claim before the first one finished.
- Two staff members each billed the same visit.
- A correction was sent as a new claim instead of an adjustment.
That last one matters. When a paid claim needs a change, use the adjustment route and watch its deadline: three months from the month of payment in Georgia’s guidance.
One person should own the billing calendar so that nothing goes out twice.
