Remittance Advice · Payment-time (remittance)
OHIP explanatory code 51
Fee Schedule Code changed in accordance with Schedule of Benefits
What 51 means
The Ministry of Health’s official wording for 51 is: “Fee Schedule Code changed in accordance with Schedule of Benefits.”
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 51
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.
