What V10 means
The Ministry of Health’s official wording for V10 is: “Patient's last name is missing/not alphabetic (A-Z) First field position is blank.”
This code appears on your Claims Error Report (downloaded through MCEDT). It means the claim was rejected at submission and was never adjudicated for payment — fix the issue below and resubmit the claim.
How to fix V10
Enter the patient's last name (letters A-Z, with the first position filled) and resubmit.
These codes relate to the fee schedule code, diagnosis code, fee amount, or service limits in the Schedule of Benefits. The fix usually starts with re-reading the code's payment rules — effective dates, age/sex limits, maximums, and combinations — for the date of service.
