OHIP error code EPP
Incorrect Code for Eligibility (Ontario Works/Ontario Disability Support Program)
What EPP means
The Ministry of Health’s official wording for EPP is: “Incorrect Code for Eligibility (Ontario Works/Ontario Disability Support Program).”
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 EPP
Use the correct code for the patient's eligibility program (Ontario Works / ODSP) and resubmit.
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.
