How do I fix OHIP error code EA?

Check the amount paid on the line. Tell the patient that OHIP shows them as not eligible and ask them to contact ServiceOntario as soon as possible. Run a health card validation check before the patient's next visit. If the patient's eligibility is corrected for the service date and the line wasn't paid, send a Remittance Advice Inquiry (RAI) through eSubmit, or on form 0918-84, within 7 months of the RA date.

When shouldn't I resubmit a EA claim?

The claim is already on your RA. A new claim for the same service will be treated as a duplicate. Use an RAI instead.

EA warns the patient wasn't eligible on the service date. Services on or after the 20th of this month won't be paid unless that changes.

What it means

EA appears on the Remittance Advice (RA) when the service date is not within an eligible period for the patient. It also warns that services on or after the 20th of this month will not be paid unless the patient's eligibility status changes.

It is both an explanation for this line and a warning about future claims for the same patient.
