OHIP error code EQ4
Claim submitted as Pay Provider - Health care provider is registered as OPTED-OUT for date of service
What EQ4 means
The Ministry of Health’s official wording for EQ4 is: “Claim submitted as Pay Provider - Health care provider is registered as OPTED-OUT for date of service.”
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 EQ4
You're opted-out for this date - resubmit the claim as Pay Patient rather than Pay Provider.
Referral and provider codes relate to the referring or rendering provider number, specialty restrictions, or referral requirements attached to the fee code. Verify the provider numbers on the claim and whether the code requires a valid referral.
