How do I edit or cancel a submitted claim
If the claim is under Submitted status, unfortunately, the claim cannot be edited as it has been transmitted to MSP.
1) If you discover the incorrect submission before the MSP close off date, you can call MSP Teleplan (1-866-456-6950 ext 3 - 2) and ask them to "zap" (cancel) your claim. You will be asked for your Data Centre number (MDBilling.ca Data Centre No.: T1919) and the sequence number (see the bottom of the claim page).
You can then create a new claim with the correct information right after the request is made. The original claim will be processed in the next RA as refused for payment with the explanatory code FC:
This account has been paid or refused in accordance with previous correspondence, phone call or note record.
2) If the mistake is found after the MSP close off date, you will have to wait until the remittance arrives and see if the claim is paid. If it is, you will need to submit a Debit Request to withdraw the payment.
