How do I fix OHIP error code ME?

Count the e-assessments of the same type paid for the patient in the last 12 months. If the request was for a clearly different diagnosis, check the record shows it. A later e-assessment for the same diagnosis may be payable as a repeat, follow-up or minor e-assessment instead (Schedule GP37). If you believe the decision is wrong, send a Remittance Advice Inquiry (RAI) through eSubmit, or on form 0918-84, within 7 months of the RA date, with supporting details.

When shouldn't I resubmit a ME claim?

The limit for that type of e-assessment was reached. The line is already on your RA. Question it with an RAI, not a new claim.
