OHIP error code EH2

Mismatched Version Code

What EH2 means

The Ministry of Health’s official wording for EH2 is: “Mismatched Version Code.”

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 EH2

Get the current version code from the card or via Health Card Validation and resubmit. A renewed card's old code will never clear.

Eligibility and health card codes relate to the patient's health number, version code, or OHIP eligibility on the date of service. Most are fixed by re-checking the card (or using Health Card Validation) and correcting the patient details before resubmitting.
