OHIP error code EF4
Provider is not approved to bill ICHSC fee on date specified
What EF4 means
The Ministry of Health’s official wording for EF4 is: “Provider is not approved to bill ICHSC fee on date specified.”
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 EF4
You aren't approved to bill this ICHSC fee on the service date - confirm your approval with the Ministry, then resubmit.
Program-specific codes come from claims routed through special programs — Reciprocal Medical Billing for out-of-province patients, WSIB, telemedicine/virtual care, and Integrated Community Health Services Centres. The fix depends on that program's own submission rules.
