OHIP error code EF8
'I' service codes are exclusive to ICHSCs
What EF8 means
The Ministry of Health’s official wording for EF8 is: “'I' service codes are exclusive to ICHSCs.”
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 EF8
'I' service codes can only be billed by an ICHSC - use the appropriate non-'I' code, 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.
