OHIP error code V16
Unacceptable Diagnostic Code Not numeric
What V16 means
The Ministry of Health’s official wording for V16 is: “Unacceptable Diagnostic Code Not numeric.”
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 V16
The diagnostic code must be numeric - enter a valid 3-digit numeric OHIP diagnostic code 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.
