OHIP explanatory code J1
Service Date is Before the Effective Date of OHIP Coverage
What J1 means
The Ministry of Health’s official wording for J1 is: “Service Date is Before the Effective Date of OHIP Coverage.”
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 J1
Check the patient eligibility and health card for the service date. If they were covered, file a Remittance Advice Inquiry; otherwise bill the correct payer.
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.
