What EQK means
The Ministry of Health’s official wording for EQK is: “Master Number (MNI) Does not Meet Criteria - A100 billed with a specialty code other than 00..”
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 EQK
A100 can only be billed under specialty 00 - bill the appropriate code for your specialty instead, then resubmit.
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.
