OHIP explanatory code RD
Duplicate, paid in Reciprocal Medical Billing System (RMBS)
What RD means
The Ministry of Health’s official wording for RD is: “Duplicate, paid in Reciprocal Medical Billing System (RMBS).”
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 RD
OHIP shows this was already paid - confirm it is not a true duplicate; file a Remittance Advice Inquiry with detail if the service was genuinely separate.
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.
