OHIP error code EF1

ICHSC number not approved for billing on the date specified

What EF1 means

The Ministry of Health’s official wording for EF1 is: “ICHSC number not approved for billing on the 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 EF1

The ICHSC number isn't approved to bill on that date - confirm the centre's approval for the service date 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.
