OHIP explanatory code L7
Not allowed-referred specimen
What L7 means
The Ministry of Health’s official wording for L7 is: “Not allowed-referred specimen.”
This code appears as an explanatory code on your monthly Remittance Advice (RA). It means the claim was adjudicated — paid, reduced, or refused — for the reason below. A claim already on your RA generally shouldn't be blindly resubmitted; follow the suggested action.
How to fix L7
This explains a payment adjustment. If you believe the claim was billed correctly, file a Remittance Advice Inquiry within the deadline; otherwise no resubmission is needed.
Payment-time codes appear on the monthly Remittance Advice after adjudication. Some are informational, some explain a reduced or refused payment. Where you disagree with the outcome, the usual route is a Remittance Advice Inquiry or written inquiry — not resubmitting the same claim, which can create a duplicate.
