OHIP error code PA4
PA Registration on Service Date Error
What PA4 means
The Ministry of Health’s official wording for PA4 is: “PA Registration on Service Date Error.”
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 PA4
Confirm the Physician Assistant was registered for the PA Pilot on the service date, correct the registration or date, 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.
