Exact Duplicate Claim/Service
The payer's system has already received and processed an identical claim for this patient, date of service, and procedure — this submission is being treated as a repeat, not a new claim.
Guided troubleshooter available for this denial
Answer a few questions to reach the correct disposition. No patient or claim identifiers requested.
In plain language
The payer's system has already received and processed an identical claim for this patient, date of service, and procedure — this submission is being treated as a repeat, not a new claim.
Start here
Check claim status in the payer portal before resubmitting anything.
Who resolves it
Billing/Follow-Up
Who prevents it
Information Systems/Billing — duplicate-claim detection logic in the claim-submission system; Denials/Follow-Up — workqueue discipline to check status before resubmitting.
How to resolve this denial, step by step
- 1
Check claim status in the payer portal before resubmitting anything.
- 2
Confirm whether the original claim was paid, denied, or still in process.
- 3
If a correction is needed, resubmit as a replacement claim (frequency code 7) referencing the original claim/ICN — not a new claim.
- 4
If this is a true system-generated duplicate with no intended change, no action is needed; document and close.
- 5
If a crossover duplicate, confirm crossover status in the payer/Medicaid system before resubmitting anything.
- 6
Document findings.
Then choose the correct disposition
Corrected claim (frequency code 7)
when a legitimate correction to a previously processed claim is intended.
Payer follow-up
when crossover status needs confirmation before any resubmission.
No action
when the "duplicate" denial is correctly identifying an actual duplicate with no data change needed.
Stop and escalate when
- Payer shows no record of the original claim despite confirmed submission (potential payer processing error, cross-reference D21); crossover status cannot be confirmed after reasonable follow-up.
What Needs to Be Corrected
- Claim correction: If this was meant to be a corrected claim, resubmit using claim frequency code 7 (replacement) with the original claim number referenced, not as a new original claim.
- Upstream correction: If a system or clearinghouse auto-resubmitted without a workflow flag, the claim-submission process/interface needs a duplicate-check control.
Do Not Do This
- Do not repeatedly resubmit the same claim while waiting for the payer to finish processing the original — this creates more duplicate denials and delays resolution.
- Do not submit a correction as a new original claim instead of a replacement (frequency code 7).
