OHIP error code ADF
Corresponding Procedure Invalid, Omitted or Paid at zero
What ADF means
The Ministry of Health’s official wording for ADF is: “Corresponding Procedure Invalid, Omitted or Paid at zero.”
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 ADF
Add or correct the base procedure this code depends on - the corresponding procedure must be present, valid, and payable (not paid at zero) - then 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.
